Tried and True: Reducing Greenhouse Gas Emissions in New Zealand Through Conventional Environmental Legislative Modalities

Alon Tal^*

I. Introduction

The potentially catastrophic dimensions of climate change are particularly salient in the Pacific region, where island countries’ ability to adopt adaptation measures may be limited.¹ The gap between New Zealand’s image as an environmentally conscientious world leader from this region² and its actual performance in meeting international obligations to reduce greenhouse gas (hereinafter: GHG) emissions is therefore particularly striking.³ January 1, 2008 opened the so-called “commitment period” under the Kyoto Protocol, giving the 37 developed countries who have adopted “carbon equivalent ceilings” five years to meet specific GHG emission limitations or face sanctions.⁴ Some countries, such as Denmark and Romania are doing remarkably well – with respective emissions of 13 and 18 percent below where they were in 1990 – the baseline or reference point for GHG emissions.⁵ Unfortunately, New Zealand’s emissions since 1990 have increased by some 25 percent even as under the Kyoto Protocol, they were to remain stabilized at 1990 levels.⁶ Should GHG emissions produced by air travel associated with international tourism

in New Zealand⁷ be counted as part of the country’s GHG allowances, it would amount to 7893 kilotons of CO2 equivalents – or an additional 10 percent exceedance.⁸ While the relative contribution of New Zealand to the world’s overall greenhouse gas concentrations is small (less than half a percent of global discharges) per capita emissions are not.⁹ From the perspective of public policy, the associated activities will have to change, or New Zealand’s tax-payers will have to make a considerable outlay in purchasing “carbon credits” on international markets for reductions made in other countries.¹⁰

There are many reasons to which this lacklustre performance can be attributed. To begin with, as is often the case with “cap and trade” regimes,¹¹ New Zealand is paying a price for its generally strong environmental performance in 1990. Unlike Eastern European countries, which at that juncture were still home to heavy, polluting industries, (that soon thereafter collapsed but left generous carbon credits in their midst) New Zealand in 1990 received the vast majority of its energy from clean hydroelectric facilities and had a relatively modest fleet of cars. Economic development and the associated steep energy demands have changed that profile considerably.¹² Also, New Zealand’s idiosyncratic livestock intensity – which accounts for about a third of emissions – makes its circumstances unique. Given present trends, the Ministry of the Environment anticipates the growing dairy herd and continued energy demands to push New Zealand’s net emissions up further still, so that by 2012 levels could be more than 70 percent above those of 1990.¹³

⁷ International tourism is a growing part of the country’s economy, accounting for 19.2% of annual exports.

Lack of clear government consistency in formulating policy and an overestimation of the impact of forest sinks (that absorb CO2 and thereby improve the national GHG balance sheet) are also responsible for the present quandary. Twice, the government embraced taxes (once for “sheep burps” and the other a general “carbon tax”) only to change its mind. Recently, Parliament adopted a carbon emissions “cap and trade” program as the centre piece of national climate change policy.¹⁴

In this sense, New Zealand has happily joined the general international fixation with market mechanisms and “cap and trade” systems,¹⁵ as a “cost-effective” and politically palatable, way to meet the challenge of mitigation of greenhouse gases. In the past, most environmental problems were addressed through “command and control” legislation, where an acceptable level of environmental performance was identified, or a technology recognized as cost-effective and prescribed accordingly. Due to the anticipated breadth of necessary carbon emission reductions, trading systems are expected to be more politically acceptable than conventional controls or even taxes and indeed have been adopted by the European Union,¹⁶ the UK and other jurisdictions.

And yet it would appear that the country, in its zeal to take its place at the table of creative public policy innovators, may have passed up some of the easier and more promising regulatory solutions which could close the present gap between international commitments and the domestic emissions profile. Indeed, it is argued, that sole reliance on a cap-and- trade system, will both lead to missed opportunities for cost-effective reductions in GHG emissions, as well as missed Kyoto deadlines. In this article we will consider the potential of greenhouse gas emission reductions in a variety of sectors which can be facilitated through legislation parallel to the broader cap and trade regulatory scheme that will be phased in over the next five years.

The article will begin with a brief review of the international legal history surrounding present legislative activity, and the expectations that New Zealand must meet under the United Nations Framework Convention on Climate Change (UNFCCC) and its subsequent Kyoto Protocol. A brief description of existing legislation that has emerged in response will follow, with an emphasis on its limitations. A brief

presentation of the “Socolow” carbon wedge paradigm will be presented as a general context for several proposed legislative initiatives to reduce GHG emissions. Then the article will consider four areas in which potential interventions exist for reducing New Zealand’s greenhouse gas emissions and legislative mechanisms for facilitating them. Examples of regulatory schemes already in place in other jurisdictions will be mentioned as possible models for future legislation. These measures may not be part of the fashionable “cutting edge” economic instruments, but in many cases, they may be more effective. And as it is already clear after the 2007 Conference of the Parties to the UNFCCC held at Bali¹⁷ that the Kyoto emission targets will become more stringent over time, they may provide some of the solution for what is certain to be a growing challenge for environmental law.

II. The International Framework for Addressing Climate Change

The UNFCCC

By the late 1980s a sufficient number of scientists were convinced that the planet was warming and that the ecological consequences could be severe to bring the issue of climate change into the centre stage of international discourse. Even such an unlikely advocate as UK Prime Minister Margaret Thatcher dedicated her final speech to the UN General Assembly in 1989 to the topic, calling on the family of nations to urgently adopt a framework convention to address the issue.¹⁸ Soon thereafter, the General Assembly established an Intergovernmental Negotiating Committee to begin the complex drafting process.¹⁹

¹⁷ For a review of the most recent conclusions of the UNFCC’s Conference of the Parties in Bali (COP13) see: United Nation Framework Convention on Climate Change, COP13, Bali, 2007 (http://unfccc.int/meetings/ cop_13/items/4049.php).

¹⁸ “The most pressing task which faces us at the international level is to negotiate a framework convention on climate change – a sort of good conduct guide for all nations. Fortunately we have a model in the action already taken to protect the ozone layer...that aims to prevent rather than just cure a global environmental problem. But a framework

is not enough. It will need to be filled out with specific undertakings, or protocols in diplomatic language, on the different aspects of climate change. These protocols must be binding and there must be effective regimes to supervise and monitor their application. Otherwise those nations which accept and abide by environmental agreements, thus adding to their industrial costs, will lose out competitively to those who do not. The negotiation of some of these protocols will undoubtedly be difficult. And no issue will be more contentious than the need to control emissions of carbon dioxide, the major contributor – apart from water vapour – to the greenhouse effect. We can’t just do nothing.” Margaret Thatcher, speech to the United Nations General Assembly, November, 8,

^{Law 76.}

By then an Intergovernmental Panel on Climate Change (IPCC) was already actively considering the scientific controversies that the issue evoked. Established by the World Meteorological Organization and the United Nations Environmental Program, the IPCC was designed to be a broad international scientific body that would review the scientific evidence about climate change and prepare reports that reflect the prevailing viewpoints within the scientific community.²⁰ Their periodic reports expressed growing consensus among scientists that the world was growing warmer and that anthropogenic emissions of greenhouse gases were the proximate cause for the steady increase in temperature.²¹

After several rounds of stormy negotiations,²² a draft of a general framework agreement had sufficiently coalesced to be part of the documents which were reviewed, and ultimately approved at the United Nations Conference on Environment and Development in Rio de Janeiro in 1992.²³ The framework convention was far less ambitious in its scope and expectations than advocates of a global initiative to address climate change had hoped for. The convention paid lip service to a number of principles that were by then popular in international environmental law, including “common but differentiated responsibilities”²⁴ which put

²⁰ The IPCC defines its mission as to “assess on a comprehensive, objective, open and transparent basis the latest scientific, technical and socio- economic literature produced worldwide relevant to the understanding of the risk of human-induced climate change, its observed and projected impacts and options for adaptation and mitigation.“ See generally “About the IPCC” on the organization’s web-site: http://www.ipcc.ch/about/ index.htm. The work of the IPCC was sufficiently exemplary in shaping the international discourse and forging a consensus that the body and its thousands of members were awarded a Nobel Peace Prize along with Al Gore in 2007.

²¹ “We are certain of the following: there is a natural greenhouse effect...; emissions resulting from human activities are substantially increasing the atmospheric concentrations of the greenhouse gases: CO2, methane, CFCs and nitrous oxide. These increases will enhance the greenhouse effect, resulting on average in an additional warming of the Earth’s surface. The main greenhouse gas, water vapour, will increase in response to global

In a relatively strong environmental response to the ongoing scientific debate about the magnitude of human contribution to global warming, it also contains a strong adoption of the “Precautionary Principle”.²⁶ But the resistance of the United States to the designation of quantifiable emission targets and implementation timetables left it devoid of operational expectations.²⁷

The convention did expect parties to maintain inventories and reports about anthropogenic emissions by sources and removals by sinks of all greenhouse gases²⁸ as well as establish financial mechanisms to assist developing countries.²⁹ All countries were expected to prepare programs and policies that would spell out those measures that were to be employed to mitigate climate change.³⁰ Yet, there were no prescriptive specifications with regards to the magnitude of emissions reductions or the form such mitigation measures might take. Perhaps most important, in retrospect, the convention established the necessary infrastructure for future initiatives and interventions to address climate change. These included the establishment of a Secretariat based in Bonn, a Global Environmental Facility that would be able to fund the necessary activities among developing countries and of course a governance system that would allow the parties to the convention to expand its mandate through Protocols³¹ and expectations over time.

and the agreement came into force on March 21, 1994, less than two years after it was adopted in New York.

The Kyoto Protocol

It was soon evident that the “framework” convention had provided little but the proverbial normative skeleton, and that the “meat” would have to be added in subsequent agreements by the parties. No sooner had the convention come into force than a coalition of environmentalists and developing countries began lobbying for meaningful commitments in the form of targets and timetables for reducing GHG emissions.³² The first conference of the parties in 1995 produced the so-called “Berlin Mandate” that set a process in motion that culminated in a Protocol’s approval on December 11, 1997 at COP3 in Kyoto.³³ When US Vice-President Al Gore agreed to attend the Kyoto meeting and directed his American delegation to show flexibility in setting emission targets, conditions were ripe for a substantive agreement that went far beyond the framework convention in its objectives and level of specificity. ³⁴

The Kyoto Protocol maintains the UNFCCC’s dichotomy between developed and developing nations, with the bulk of the commitments made by the former “Annex 1” countries that now included several Eastern European nations defined as having “economies in transition”.³⁵

Article 3 sets out the collective objective of reducing the overall GHG emissions of this group by “at least 5 percent below 1990 levels in the commitment period 2008-2012”.³⁶ Greenhouse gases, descriptively described in the original convention were now listed in Annex A of the Protocol as:

• Carbon dioxide (C02)

• Methane (CH4)

• Nitrous oxide (N20)

• Hydrofluorocarbons (HFCs)

• Perfluorocarbons (PFCs)

• Sulphur hexafluoride (SF6)

From this group, carbon dioxide, is by far the least efficient at absorbing infrared rays and contributing to a global warming. Yet, because its concentrations are so much higher than the other greenhouse gases, its role in global warming is “predominant”, contributing 80 percent of the “greenhouse effect” from current GHG emissions.³⁷ As a result it serves

as the “benchmark” for evaluating the potency of all GHG emissions, with other gases being assigned “CO2 equivalents”.

The Kyoto Protocol was considered a “path-breaking” international agreement for many reasons, chief among these was its embracing of “trading” or flexible mechanisms. These four modalities allow Annex I countries to meet their emission targets, by paying sources in other countries to reduce emissions in their stead (or to expand their absorption) of greenhouse gases. For instance the Clean Development Mechanism (CDM) allows Annex I parties to pay for implementation of projects that reduce emissions that otherwise would not be taking place in non- Annex 1 countries and receive credit for the associated CO2 equivalent reduction.³⁸ Alternatively, Joint Implementation projects allow an Annex I country to implement an emission-reducing project (or undertake one that removes carbon) in another Annex 1 country, and count the resulting reduction in emissions in meeting its own Kyoto target.³⁹

In essence, the Kyoto Protocol adopted a global “cap and trade” system, largely based on the environmental and economic success of a conceptually similar pioneering programme that reduced emissions of sulfur dioxide (and the resulting acid rain) in the United States during the 1990s.⁴⁰ The global atmosphere is presumably indifferent to the specific origins of where greenhouse gases arise. So the Kyoto Protocol sought to create a framework in which emission sources would be abated and sinks that sequestered carbon would be expanded in places where

it would be cheapest to do so.⁴¹ Many countries were uncertain about their ability to reduce their emissions cost-effectively and consequently were wary of making commitments to that end. Accordingly, their concerns were assuaged and they were induced to accept quantifiable emission reduction targets with the knowledge that if they needed to, such emission reductions could be purchased in other countries, where presumably they could be attained less expensively.

The cap and trade system is not without its challenges, and ensuring compliance is not necessarily easier than overseeing conventional “command and control” environmental regulation.⁴² But the Protocol’s emission trading orientation meant that the international community could make a meaningful commitment to begin the process of reducing GHG emissions, and rely on a global market to minimize the costs of a most daunting venture.

The Kyoto Protocol, by definition was a flawed instrument, limited by the complex political dynamics of global politics. The absence of any real commitment by developing countries to reduce GHG emissions⁴³ meant that a growing fraction of global emissions would not be regulated and that industries in Annex 1 countries might be disadvantaged when competing with firms operating in developing countries where GHG emissions were not regulated.⁴⁴ The United States continues to base its refusal to ratify the convention on this omission.⁴⁵ Indeed, it would take a full eight years, until February 16, 2005, for the Protocol to enter into force, almost a decade after it was negotiated. Yet, the ability of the UNFCCC COP13 gathering at Bali to hammer out a “road map” for negotiating further reductions by Annex 1 countries and the expeditious adoption of mitigation strategies by non-Annex 1 countries⁴⁶ suggests that the framework is durable and will serve as the basis for most countries of

the world. Certainly, for the foreseeable future, its demands, targets and timetables will drive New Zealand’s greenhouse gas emission policies and legislation.

III. New Zealand’s Response to Global Climate Change

One of the ironies about the effect of global warming is the diversity of its impacts. Climate change will undoubtedly produce “winners” and “losers”. Based on government reports, it would seem that New Zealand may derive more benefits than damage from the anticipated raise in global temperatures.⁴⁷ Among the negative effects projected are greater floods, landslides, droughts and storm surges. Higher temperatures might compromise the profitability of some fruit crops in northern areas and extended dry periods are likely to reduce soil moisture (although western New Zealand is likely to receive more rain). The potential for an expanded range of some undesirable insects and pests has been raised but remains largely in the realm of conjecture.⁴⁸

At the same time, the Ministry of Environment reports suggest that there is likely to be an increase in agricultural productivity in New Zealand due to elevated carbon dioxide concentrations and improved growth rates and water-use efficiency. The new, warmer conditions and lengthened growing seasons could shift a variety of climate-limited activities, including profitable crops and industries into southern areas. Some effects may balance out: conservation biologists do not believe that a shift in temperature gradients will have a meaningful effect on biodiversity and will not exacerbate any threatened species. Heat consumption and associated costs may drop during the winter (although air conditioning usage would surely go up in the summer).⁴⁹ Tourists may appreciate the warmer temperatures, but temperature increase will surely not help New Zealand’s ski industry.⁵⁰ The IPCC projections for New Zealand are somewhat less sanguine particularly with regards to the impact of rising sea levels on coastal erosion.⁵¹ While there are

Regardless of the local impacts, New Zealand’s policies have not been driven by local interests per se, but rather a sense of international environmental responsibility. Cognizant of the potentially catastrophic impacts of global warming across the planet, New Zealand showed considerable alacrity in ratifying the UNFCCC (September 1993) although hesitated somewhat before expediting ratification of the Kyoto Protocol, only doing so on December

Climate Change Response Act 2002

The Climate Change Response Act 2002⁵³ constitutes the first major legislative ratification tool for meeting New Zealand’s obligations under the UNFCCC and the Kyoto Protocol. In fact, it prints out the full text of the two agreements as Schedule 1 and Schedule 2 of the Act. In practice, the legislation creates a comprehensive mechanism for monitoring the sources of greenhouse gases which contribute to climate change. The Act specifically defines its legislative raison d’etre as two-fold: facilitating compliance with the national 1990 GHG emission targets stipulated under the Kyoto Protocol and meeting the reporting requirements of the UNFCCC.⁵⁴ The former it does quite poorly and the latter it does quite well.

The Act’s major contribution ultimately might be deemed as institutional. The Minister of Finance is authorized to trade national emissions allowances and acquire certified emission reduction (or removal) units should this be necessary.⁵⁵ The Act instructs the Minister to appoint a registrar to record transaction details in its international dealings and act on the Minister ’s behalf to that end.⁵⁶ The registrar does

not engage in the actual calculation of domestic emissions. This task falls to the Inventory Agency that is established by the law⁵⁷ to estimate annually New Zealand’s human-induced GHG emissions by sources and removals by sinks of greenhouse gases and to prepare the necessary reports for the purpose of discharging New Zealand’s obligations under Article 7.1 of the Kyoto Protocol.⁵⁸ The Inventory Agency operates out of the Ministry for the Environment.⁵⁹ The precise methodology for characterizing emissions is of course based on the IPCC-approved accounting system.

For example, an individual can open a holding account for removal units and transfer the rights to these units (according to the specified fees), including bequeathing them to one’s heirs.⁶¹ Moreover, New Zealand has regularly met its reporting obligations under the UNFCCC.⁶² Yet, much like a competent accounting department in a business that is failing, it would appear that the best that the Inventory Agency has been able to do is to count the growing deficit in certified emissions reduction units, due to the steady climb in local GHG emissions.

The Resource Management (Energy and Climate Change) Amendment

^{Act 2004}

The Resource Management (Energy and Climate Change) Amendment Act 2004 is one of the more curious pieces of legislation on climate change that has been introduced internationally. The bill was introduced to the House of Representatives in July 2003 on the basis of conclusions made by the Ministerial Group on Climate Change that the current Resource Management Act (RMA) did not adequately consider the effects of climate change.⁶³ Yet, the apparent ambivalence of legislators not only

projects a mixed message – but a mixed mandate.

Ostensibly the amendment corrected this situation: The RMA Interpretations in s 2 now include a definition of “climate change”⁶⁴ and s 7 of the Purposes and Principles Part now require that:

all persons exercising functions and powers...in relation to managing the use, development and protection of natural and physical resources, shall have particular regard to:

(b) the efficiency of the end use of energy

(i) the effects of climate change

(j) the benefits to be derived from the use and development of renewable

^energy.65

Yet, at the same time Parliament expressed concern that local resource management decisions could be excessively influenced by climate change considerations. Accordingly, the purpose of the Act at once calls for local authorities to plan for the effects of climate change; but “not to consider the effects on climate change of discharges into air of greenhouse gases.” A series of operational provisions explicitly prohibit climate change considerations when local planning decisions are made – presumably in order to preserve harmonization in national policy on the subject. Accordingly, the RMA’s s 70 now reads: “when making a rule to control the discharge into air of greenhouse gases under its functions under s 30(1)(d)(iv) or (f), a regional council must not have regard to the effects of such a discharge on climate change.”⁶⁶ At the same time, the Act allows consideration of: “the use and development of renewable energy” if it enables a reduction in the discharge into air of greenhouse gases, either – in absolute terms or relative to the use and development of non-renewable energy. Identical limitations were placed on local discretion in the areas of discharge or coastal permits.⁶⁷

It should not have been surprising that this flagrant incongruence would be the focus of litigation, the most significant of which reached the Court of Appeal in December, 2007. In Genesis Power Ltd v Greenpeace New Zealand, Inc⁶⁸ the Court of Appeal was asked to offer declarative relief. As a major electricity utility, Genesis Power felt uncomfortable with an

earlier High Court decision regarding the establishment of a power plant proposed by the Mighty River Power Ltd company. In their arguments to the High Court, environmental advocates at Greenpeace based their objections on the impact of the facility on climate considerations in the context of s 104E of the RMA.⁶⁹

In the previous High Court ruling, Williams J had favoured an environmentally ambitious interpretation of this section. He held that the RMA enabled the consent authority to balance the power station activity alongside any proposal by the applicant which would effect “reduction in the discharge into air of greenhouse gases”.⁷⁰ Greenpeace argued that the operation of the coal-fired station would in effect subsidise the New Zealand coal industry (by enabling it to avoid internalising the cost to the country and the environment of GHG emissions). The result of a narrow interpretation would allow for coal generated electricity to be produced far more cheaply, essentially creating additional obstacles for renewable energy in New Zealand.⁷¹

But the Court of Appeal opted to agree with the Genesis position which argued that the exception which allows for consideration of the benefits of renewable energy should only be employed where a concrete proposal actually envisages the use of renewable energy. William Young P ruled that,

“A requirement to have particular regard to...the benefits of renewable energy” does not necessarily entail a requirement to have particular regard to the “disbenefits” in terms of climate change of non-renewable energy generation. In the particular statutory context, and for the reasons already given, we do not equate the absence of a positive factor as amounting to a negative factor. To allow proposals to provide energy from non-renewable sources to be evaluated against a general baseline that renewable energy production is better would necessarily cut right across the prohibition in s 104E.⁷²

While the decision is a logical one in light of the fairly clear statutory language and even clearer legislative intent, it does confirm the fairly feeble commitment in New Zealand’s laws and regulations to promote economic activity and guarantee that power sources address the country’s problematic GHG emissions portfolio. To be sure there are other statutes which although not necessarily designed specifically as “climate change” laws, do contribute to public policy to reduce GHG emissions. For instance the Energy Efficiency and Conservation Act 2000, and the Energy Efficiency and Conservation Authority (EECA) created under it presumably contribute to the promotion of energy efficiency

and conservation across all sectors of the economy. Indeed, the Energy Efficiency (Energy using Products) Regulations promulgated in 2002 formalize efficiency standards on common energy intensive items. Strategies have been formulated in areas as diverse as transportation, energy conservation and wastes to galvanize thinking and increase awareness about available alternatives to GHG intensive activities. Yet, the results have not been sufficient.

The Rise and Fall of Climate-driven Tax Legislation

Two notable efforts to introduce taxes on GHG emissions are important in the context of a historical survey of New Zealand’s climate change legislation and policy. One involved the failed attempt to respond to New Zealand’s idiosyncratic GHG emissions profile and the inordinate contribution of agriculture (48.5 percent) most of which is a result of methane emissions from livestock.⁷³ In June 2003, the New Zealand government introduced a plan to impose a tax on livestock (amounting to $8.4 million a year) as an incipient step to combat global warming. The tax was to be paid by farmers and the associated revenues would fund a new Agriculture Emissions Research Body to meet commitments to the Kyoto Protocol, namely reducing the production of greenhouse gases from livestock.

The virulence of the resulting “hue and cry” was unanticipated. Some 1000 farmers stormed New Zealand’s Parliament in protest of the proposed tax, which they claimed was “unnecessary, unfair and potentially damaging to the economy”.⁷⁴ The position of the agricultural sector held that as the benefit of the reduction in emissions from such a tax would be enjoyed by the general public, the general public should participate in any associated costs.

One reason for their strong aversion to the proposal was that with farmers already facing hard times due to a sharp downturn in returns for their produce, the levy would further disadvantage farmers struggling to compete against less conscientious nations. As reducing GHG emissions would benefit everyone, farmers argued that the tax should be absorbed by all taxpayers and not be sector-specific. Opponents also

⁷³ Farm products may constitute over half of New Zealand exports, but they are also responsible for much of its greenhouse gas emissions. Agricultural emissions are dominated by livestock; methane emissions from livestock currently account for 32% of NZ’s (NZ) Greenhouse Gas (GHG) emissions. Agricultural methane comprises 87% of total methane emissions and alongside nitrous oxide produced from agriculture comprises 49.5% of NZ total emissions. www.maf.govt.nz/mafnet/ rural-nz/sustainable-resource-use/climate/abatement-.

^{74 The New Zealand Herald, June 20, 2003.}

argued that the contribution of GHG emissions from sheep and cattle, relative to factories in other industrialised countries, was ultimately trivial. The government quickly capitulated to the high profile protest and in lieu of the tax instituted a research programme to consider animal emission reduction alternatives that was funded out of the general state coffers.⁷⁵

The second and more recent foray into the realm of taxes to attain GHG emissions reduction was a government proposal for a comprehensive carbon tax. Set to come into effect in April 2007, it was cancelled in December 2005 long before it got off the ground. While many economists have advocated such measures for some time,⁷⁶ this would have been the first comprehensive carbon tax in the world. Although most energy related activities would be taxed, based on the experience of 2003 the proposed carbon tax specifically excluded methane and nitrous oxide gases from the agriculture sector, notwithstanding their prodigious contribution to over all emission levels.⁷⁷ Government estimates held that the tax, initially proposed to be NZ$11/ton would have added 6 percent to household energy prices – the equivalent of NZ$4/month. Many businesses were projected to have to pay an extra 9 percent. Revenues would initially produce NZ$360 million a year. Until the completion of the Kyoto first Commitment Period, the tax was not to exceed $25/ton.

There are several reasons that have been given for the cancellation of the proposed tax. Officially the government cited the high costs to the economy.⁷⁸ The rise in oil prices had already produced much of the behavioral change anticipated by the tax on petrol.⁷⁹ But in practice, it appears then it was a classic case of sliding down a “slippery slope”. With the best of pragmatic intentions, the government signaled its willingness to consider exemptions for particular energy intensive industries (eg, Comalco Aluminium which uses 15 percent of the country’s power or Carter Holt Harvey, the country’s biggest sawmill) if they adopted the world’s-best-practice standards of emissions. It did not take long for a deluge of requests for such waivers to appear from a range of producers, all of whom could claim special circumstances. The subsequent

negotiations dramatically reduced the potential environmental benefits that the tax was intended to achieve.⁸⁰ Ultimately, the government had the good sense to abandon the initiative before it reached legislative fruition in Parliament as it clearly would no longer “deliver the goods” nor bring New Zealand close to its Kyoto emissions commitment.

Climate Change Response (Emissions Trading) Amendment Act 2008

After many years of discussion and preparation by an interdisciplinary team of economists, attorneys and environmental scientists,⁸¹ the Climate Change (Emissions Trading and Renewable Preference) Bill (hereinafter: “CCB”) was tabled in Parliament on 4 December 2007. The CCB’s stated purpose was to allow New Zealand to meet its Kyoto obligations⁸² by adopting what constitutes the world’s most comprehensive “cap and trade” regulatory scheme ever applied on a national level.⁸³ Under “cap and trade” programs, emission rights are defined according to a particular unit (eg, tons of SO2, CO2, etc) and then a regulatory “cap” of maximal total emissions is set that presumably reduces or is an acceptable level of pollution. The total carbon equivalent emissions are then allocated to all potential sources of emissions⁸⁴ and monitored via a registry. A market is then created where the rights to emit are bought and sold.⁸⁵

Presumably, the system facilitates the most efficient reduction of emissions possible. When a firm finds that it can reduce its emissions at a price below the going market rate for the same number of carbon units, it will choose to do so and sell its units accordingly. For many years environmentalists were wary of such economic instruments for promotion of environmental ends on ethical⁸⁶ and practical grounds.

With the success of the American sulfur dioxide program, this opposition has largely dissipated.

On September 7, 2008, the extensive trading provisions of the CCB were separated from the original proposed legislation,⁸⁷ and on September 25, Parliament enacted the Climate Change Response (Emissions Trading) Amendment Act 2008 (hereinafter: the CCRETA).⁸⁸ The CCRETA itself is an expansive piece of proposed legislation, (the explanatory notes of the bill came to over 100 pages) making a thorough description of the Bill and its many substantive nuances and sectoral directives beyond the scope of the present article.⁸⁹ The following is a simplified description of ground-breaking legislation whose implementation will undoubtedly be the focus of considerable international attention.

The law is formatted as a series of amendments to the CCRA that establishes the groundwork and timetable for phasing in a comprehensive GHG emissions trading program.⁹⁰ This is based on an expansion of the CCRA’s existing New Zealand Emission Units Register which will now process New Zealand Units (NZUs) of emission credits. These can be transferred between account holders once they are allocated or purchased. The CCRETA seeks to integrate these into the international, Kyoto affiliated market allowing for trading with overseas parties.⁹¹

A second part of the initial bill that created a ten-year moratorium on fossil-fuelled thermal electricity generation in New Zealand (except in special circumstances, in particular the need to ensure the security of New Zealand’s supply) is not part of the new statute.⁹²

The proposed New Zealand emission trading system is to be phased into different economic sectors over time.⁹³ Significantly, forestry

and agriculture which have typically been excluded from other “cap and trade” initiatives internationally are integrated into the program, albeit the agricultural trading system will only come into force in 2013. Allocations of carbon credits are to be made by the Minister after having considered requests by individuals claiming that they are eligible for free allocations, and subject to public comments.⁹⁴

Participants in the system are individuals who carry out activities that produce (or absorb) GHGs as set forward in the schedules at the end of the CCRETA.⁹⁵ Once their scheduled obligations begin, they are expected to register and maintain holding accounts,⁹⁶ calculate their emissions and surrender an emission unit for every ton of greenhouse gas that they produce. Participants whose activities remove GHGs from the atmosphere are able to earn a unit for every ton of CO2 equivalents removed.⁹⁷ If participants’ actual emissions exceed their allowance they will have to buy extra units.

The trading system relies on the monitoring conducted by the participants in the system who are expected to calculate their emissions and report them between January 1st and March 31th on an annual basis.⁹⁸ All emission trading programs have to ensure the reliability of the information provided. To ensure effective oversight, a “chief executive” will administer the program, and is empowered to request relevant information from participants about their emissions (or removals) as

As described, the regulatory prescriptions will be phased in slowly and the law will undergo a lengthy, gradual period of implementation. It will take many years for the GHG reductions to be felt. It is not clear that the problem of climate change can wait that long. Besides, by adopting a cap and trade system as its sole strategy it appears that New Zealand will pay an economic price in the purchasing of carbon credits on an international market that may be extremely expensive. Experience from around the world suggests that may not be necessary. The following section considers a variety of initiatives, providing immediate cost- effective interventions and policies for reduction of local emissions.

IV. Carbon Wedges – and the Logic of GHG Emissions Regulation Physics Professor Robert Socolow and colleagues from Princeton University have proposed a widely accepted paradigm for addressing

^{the seemingly impossible task of reducing global emissions of greenhouse}

^{gases by the amount deemed necessary by the IPCC.101 In order to}

^{avoid the anticipated doubling of CO2 emissions over the next 50 years,}

^{Socolow proposes a menu of “no-carbon” or “low-carbon” strategies}

^{which would stabilize emissions at present levels. As no single strategy}

^{can provide the full requisite reduction, he proposes that the total amount}

^{be divided into fractions that are called “wedges”. The concept is}

^{featured at the end of Al Gore’s Academy Award–winning documentary}

^{An Inconvenient Truth. A long laundry list of wedges is proposed – from}

^{wind power to improving lighting efficacy. All are based on existing}

^{technologies, but require regulatory and legislative intervention for}

^{wide-spread adoption:}

To assess the potential of various carbon mitigation strategies, the concept of “stabilization wedges” is useful. The difference between the currently predicted path and the flat path from the present to 2054 gives a triangle of emissions to be avoided (see Figure 1a), a total of nearly 200 billion tons of carbon. This “stabilization triangle” can be divided into seven triangles – or “wedges” – of equal area (see Figure 1b on page 11). Each wedge results in a reduction in the rate of carbon emission of 1 billion tons of carbon per year by 2054, or 25 billion tons over 50 years.¹⁰²

The following list specifies the wedges which Socolow recommends as

All of the technologies that are suggested by Socolow have been shown to be cost-effective in sundry contexts and many might produce meaningful reductions in New Zealand’s GHG portfolio. If, however, local climate change strategy is based on the emissions trading system set forward under the CCRETA, it may take many years until meaningful economic incentives emerge to produce them. Since the measures proposed by Socolow make economic sense at both the micro and macro levels, there is considerable logic for promulgating rules that would expedite these measures, without waiting for the phase-in of a given economic sector into the evolving trading system. Empirical evidence

has shown that cap and trade systems are given to political pressures which can mean that reductions by key sectors, which could reduce emissions at relatively little expense, are not pursued.¹⁰⁴ Indeed, one of the key criticisms of cap and trade systems is that once allowances are allocated under a cap and trade system, GHG emission sources with sufficient allowances may not have sufficient reason to reduce emissions and critical opportunities will be foregone.¹⁰⁵ Indeed, Suzi Kerr, one of the key architects of the proposed New Zealand cap-and-trade model and an articulate advocate internationally for emissions trading systems acknowledges:

In some cases, the information required to make efficient decisions, even when a carbon price exists, is too complex for the actors involved, or the transaction costs of making efficient decisions is too high. In these cases (for example energy efficient light bulbs or home insulation) performance standards can be effective.¹⁰⁶

These reservations become especially compelling when the actual profile of New Zealand emissions emerges. The Ministry for the Environment reports the following profile of GHG emissions:

Energy 33,481.7 Gg, (43.4%) Industrial Processes 4,336.7 Gg, (5.6%) Solvents 48.4 Gg, (0.1%) Waste 1,847.1 Gg, (2.4%) Agriculture 37,445 Gg, (48.5%)

Despite being the major source of GHG emissions, agricultural emissions are not scheduled to be integrated into the emission trading system for many more years. Moreover, as substantial reduction potential exists among GHG producers that will not be targeted as “points of obligation” (the actual entity that is required to report GHG emissions for a given sector)¹⁰⁷ other players in the sectors’ chain of production may not end up shifting technologies or internalizing GHG emission reduction costs.

¹⁰⁴ This, along with the inherent turbulence of carbon markets under cap and trade systems is among the major reservations of economists and the basis for advocacy for carbon taxes. See Nordhaus, supra.

Yet another reason why the country should not limit its greenhouse gas efforts to “cap and trade” regimes is the plausible expectation that the present “cap” that is to be set, based on the Kyoto Protocol’s 1990 base-line target for New Zealand, will be substantially lower than that negotiated in the future rounds of talks at the UNFCCC. There exists a consensus that Kyoto constituted an interim agreement, but that considerably more ambitious measures will have to be taken to truly address GHG emissions if the international community is going to seriously mitigate the threat caused by climate change. There seemed little doubt at the recent Conference of the Parties in Bali that the national ceilings will need to drop even further¹⁰⁸ with the 2009 conference in Copenhagen likely to realise such an expectation.¹⁰⁹

Finally, New Zealand has a number of successful experiences in addressing environmental challenges through conventional “command and control” legislation.¹¹⁰ Among the more conspicuous are waste water treatment systems as well as controls on air pollution and noise. Such achievements could well be replicated under regulatory programs in a variety of areas to produce meaningful GHG emission reductions that also offer so-called “no regrets” generic benefits, beyond those associated with reduction in greenhouse gas emissions.

V. Translating “Wedges” Into Public Policy: A Brief Review of

^{Recent Legislation}

In the next section we will consider four potential greenhouse gas reductions – or efforts to identify “carbon wedges” in a variety of sectors in New Zealand, based on the magnitude of present GHG emissions and the legislative experience in other jurisdictions. These include interventions to promote greater:

• Appliance Efficiency;

• Building Standards;

• Sustainable Energy; and

• Transportation Management.

It is argued that many of these opportunities should be further explored and pursued as part of a comprehensive national climate change policy for New Zealand.

These areas of public policy were selected not only because the technologies existed, but because legislation and regulation internationally had already begun to take hold. By contrast, such technologies as hydrogen power, clean coal or coal capture storage may not yet be commercially viable. Legislation to reduce methane reductions from livestock would go a long way to addressing the predominant component of New Zealand’s GHG profile, especially given the delayed integration of the agricultural sector into the local trading system. Because livestock are a relatively small percentage of most country’s emissions sources,¹¹¹ research to address the sector is only now beginning to emerge.¹¹² To date, no meaningful models of legislation exist internationally for inducing reductions from livestock that might provide a sound basis for emulation.

One of the most unnecessary and unfortunate wastes of energy involves “standby power” in electrical appliances. Studies have shown that electrical appliances often use as much energy when they are turned “off” or in a “standby mode” as when they were “on”. The magnitude of the phenomenon emerged in a 1993 local report which could not identify meaningful difference is electricity costs in vacation homes during periods of use and vacancy.¹¹³ “Phantom loads” or “leaking electricity” was soon recognized as a major source of inefficiency which could readily be amended through engineering and technology diffusion via legislation. The phenomenon is common in a plethora of standard household appliances (televisions, stereos, VCRs, DVD player/recorders, microwave ovens and computers) which remain inactive most hours of the day. Most households would be delighted to purchase appliances which continue to perform their key functions while consuming less electricity.

Internationally, some two percent of total electricity (which translates into one percent of total carbon emissions) is associated with “standby” power. A shift in OECD countries to appliances that are designed

¹¹¹ The agriculture sector in Ireland is responsible for 28% of total GHG emissions, and while there are general targets for reduction, this has not translated into regulatory measures.

The project enlists other stakeholders such as meat companies and major private land owners.

to reduce standby demands could already provide these developed countries on average with three percent of the reductions they need to make under the Kyoto Protocol.¹¹⁴ In New Zealand, the phenomenon appears to be extremely acute, with as much as five percent total household electricity use attributed to these “phantom loads”. The potential savings from switching appliances “off” rather than into a standby mode reaches 100 million dollars every year.¹¹⁵

The United States, which typically is not thought of as a “climate change policy” innovator has begun to take advantage of the extraordinary energy conservation potential associated with home appliances. An internal Executive Order promulgated by the President in 2001 placed restrictions on electrical products which did not meet efficiency standards that included minimum “stand by” levels.¹¹⁶ California has emerged as one of the more conscientious US jurisdictions in the area of climate change legislation and standby power is no exception. Its Energy Commission adopted a comprehensive three watt standard for standby for electrical appliances which came into force on January 1, 2006.¹¹⁷

Australia began its “standby program” with a voluntary initiative where funding for promotional policies was made available on a product- specific basis. It established a National Appliance and Equipment Energy Efficiency Committee that soon set a goal of having all electrical appliances meet a one watt standard no later than 2012. The Committee was authorized to facilitate state-wide initiatives in the field. The EU has begun to address the energy savings potential in its general 2005 directive regarding eco-design requirements for energy using products.¹¹⁸

Technology advancement is only one part of the policy challenge. Ensuring appropriate individual behavior and expediting energy efficient product diffusion is necessary to achieve the potential reduction. Studies show that “replacement” rather than energy considerations motivate most appliance purchases.¹¹⁹ Providing rebates to consumers who

replace old, inefficient appliances with newer, energy conserving ones may be an effective way to move consumers in the right direction. This is much like the air quality programmes that became popular in the US and particularly in Italy which paid owners to take old, polluting vehicles off the roads so that they might buy newer, cleaner cars.¹²⁰ Accordingly, the American state of Delaware initiated a program that paid as much as five hundred dollars per household for retiring old models of appliances and buying new, “approved” ones. The program included the purchase of qualified refrigerators, freezers and washing machines while retiring the older models.¹²¹ European appliance producers argue that if such incentive programs were adopted by the EU, it could lead to the replacement of 188 million appliances, with a carbon reduction equivalent of 18 million tons by 2020.¹²²

Such subsidies need not be limited to government. BC Hydro, a major Canadian electricity utility offered its consumers 30 dollars apiece along with convenience of collection for replacing old refrigerators. Research illustrated that many of these old models are utilized solely as storage containers yet oddly remain plugged in and largely unused in holiday cribs.¹²³

There are many reasons why such legislative provisions are promising for New Zealand. To begin with, the country already has a strong statutory and institutional base for upgrading its present standards.¹²⁴ The Energy Efficiency and Conservation Act 2000 created an Authority (the EECA) to promote energy efficiency programmes. Beyond advising the minister, the EECA is authorized to promulgate regulations that promote energy efficiency, conservation and the use of renewable sources of energy in New Zealand.¹²⁵ In 2005, the EECA

established a local “Energy Star programme”. The programme endorses products with low energy demands – including “standby” and “sleep” functions.¹²⁶ This voluntary labelling scheme is currently being phased in, starting with home electronics, domestic refrigeration appliances and office equipment.¹²⁷ In addition, Energy Efficiency (Energy Using Products) Regulations 2002 require products to meet Minimum Energy Performance Standards and Mandatory Energy Performance Labelling which are harmonised with Australian standards.¹²⁸ By the end of 2008, fourteen product classes will require mandatory labels enabling consumers to include energy efficiency in their consumer decisions.¹²⁹ Dishwashers and washing machines must show information regarding standby power,¹³⁰ but clearly these demands could easily be expanded.¹³¹

A new legislative initiative in the area of reducing standby power and diffusion of energy saving appliances appears to be promising. Implementation costs are modest and the requisite technologies are available. Even as this policy technically is applied at the “household” level, the associated burden is trivial. Individuals stand to save money from adopting standby electricity standards in the mid to long term. Hence, political barriers to “command and control” regulation should be minimal. Industries do not stand to lose competitive advantages. Indeed, subsidies for encouraging the replacement of old appliances would surely be popular. Most importantly for the present context, it would appear that appliances would not be immediately influenced if at all by New Zealand’s proposed greenhouse gas trading scheme. Alternative regulatory measures would be important.

^{Building Standards and Energy Efficiency}

It is estimated that the operation of residential and commercial buildings accounts for roughly 40 percent of all energy consumed in industrial societies.¹³² This remarkable proportion does not even include the energy consumed in the production of buildings and their materials, or the transportation energy required for material transport and urban travel – both of which are influenced critically by architectural decisions.

Improving energy-efficiency of buildings is an area where direct regulation could reduce energy use and GHG emissions significantly.¹³³

In New Zealand, conservative estimates suggest that 12.6 percent of total energy use is associated with residential buildings.¹³⁴ Yet, this is another area which largely falls outside the present emissions trading programme and where impressive energy savings might be missed. It is therefore clear that increasing the overall energy-efficiency of buildings could have a significant impact on energy consumption and greenhouse gas emissions world wide.

Improving the energy efficiency of buildings is not only technically attainable, it is also generally cost-effective. Numerous aspects of a building’s design and environmental systems affect its ultimate energy consumption, and in each of these areas there is a vast potential for savings in most countries. The recent report by the United Nations’ International Panel on Climate Change¹³⁵ confirms eariler estimates that energy use in the building sector could be reduced by 30-50 percent.¹³⁶

The potential for energy reductions in buildings in New Zealand is enormous. For example, some 61 percent of the country’s 1.5 million homes were built prior to the promulgation of present building standards when insulation became mandatory.¹³⁷ While building standards

worldwide were initially focused on protecting public health and safety, they are becoming more energy conscious.¹³⁸ Existing New Zealand building codes could be far more rigorous about energy efficiency and offer far more incentive or assistance to existing homes to improve energy performance. Beyond installation of ceiling and wall insulation, they should include such measures as utilization of double glazed windows, heat pumps/ceiling fans, lowering ceiling heights, etc.

Internationally, “Green Buildings” have been promoted world-wide though voluntary standards. The most famous of these – the LEED (Leadership in Energy and Environmental Design) labelling scheme was designed by the US Green Building Council, an interdisciplinary non- profit body of architects, engineers, academics, product manufacturers and public institutions. The first pilot version was published in 1998, and two additional versions have been introduced since. LEED is essentially an environmental performance rating system, which may be applied to new or existing commercial, institutional and residential buildings.¹³⁹

LEED was envisioned as a non-governmental program which could be implemented on a voluntary basis. Through the program projects are submitted for LEED certification as “green buildings”, usually by large companies seeking to incorporate green practices as part of their corporate agenda or concern for their public image.¹⁴⁰

The LEED program ranks building projects according to four certification levels which purport to rate the overall environmental performance of a building according to a “point system”. A building at the most basic level can be classified as Certified (26-32 points) with Silver (33-38 points), Gold (39-51 points) and Platinum (52-69 points) incrementally improving performance. Among the areas for which points are awarded are: Sustainable Sites (including questions of transportation access), Water Efficiency, Energy and Atmosphere, Materials and Resources, and Indoor Environmental Quality. Four additional points can be attained if design is particularly innovative. Prerequisites for each area exist for which buildings do not receive points, but without which, certification will not be granted.

In the present context, the category “Energy and Atmosphere” offers the greater benefits for greenhouse gas reduction. It contains three “prerequisites”: 1) fundamental commissioning of the building energy systems, 2) minimum energy performance and 3) fundamental

refrigerant management.¹⁴¹ Specifications relating to the energy efficiency of the building envelope, heating, ventilation, air-conditioning and refrigeration (HVAC&R), lighting and other systems are all based on American engineering standards.¹⁴² While it has done an excellent job of public relations, in practice the actual impact of the LEED program is smaller than would be expected given its reputation as the world’s leading building rating scheme.¹⁴³

One of the first statutory efforts to reduce GHG emissions through construction standards was undertaken by the European Union. In an effort to mobilize a community strategy to meet the Kyoto Protocol’s emission goals, the European Commission enacted the European Climate Change Program in 2000. Among the key “cost-effective” components of the strategy that it identified was the potential improvement in the energy performance of buildings, considered to be among the more cost effective measures for reducing GHG emissions.¹⁴⁴ Consequently, a Energy Performance of Buildings Directive (EPBD) was enacted in order to expedite energy efficiency in buildings within the 27 EU member states. While great effort was invested in emphasizing the cost-effective nature of the modifications,¹⁴⁵ stalled implementation has belied the ease of the transition.¹⁴⁶

The EPBD relies on the calculation of a broad range of building characteristics.¹⁴⁷ These include a structure’s thermal qualities, building position and orientation, heat recovery systems, hot water supply, and lighting. The Directive also allows for consideration of renewable

energy applications and the bioclimatic design if these exist.¹⁴⁸ The EPBD contains specific expectations with regards to minimal energy performance requirements in new buildings while existing structures are expected to undertake substantial renovations. Buildings are to undergo energy certification that includes the periodic inspection of air conditioners and boilers. Heating installations are to be replaced when bolilers are older than 15 years.¹⁴⁹

The Directive also includes considerable reporting requirements. Real estate owners are expected to report a variety of building parameters and calculation of energy values. These include the type of dwelling, efficiency rating, date of construction, floor area, and energy consumption per square metre, including the kinds of fuels consumed.¹⁵⁰ As is generally the case with EU Directives, the EPBD constitutes a generic framework, with the expectation that member countries will develop their own, site-specified methodology. To improve consistency, the European Commission has recently launched an initiative to establish a single EU building standard.

Other examples of energy driven building codes include the German energy performance certificate and a voluntary standard in Israel (SI 5281) designed by a local NGO.¹⁵¹ Yet, these programs, while more ambitious than the present New Zealand standards do not ensure the long-term maintenance of the building and its energy conservation systems nor address the predominant energy demands of older buildings.

As mentioned, New Zealand has a long-standing framework for construction standards¹⁵² and more recently has introduced a building code promulgated pursuant to the 1992 Building Regulations¹⁵³ that

contains provisions that promote energy conservation. The code wisely relies on a performance standard rather than a design standard which mandates a given construction technique or technology. As of November 2007 new homes are to meet geographically specific energy performance standards under sH1.3.2A of the Building Regulations.¹⁵⁴

The Department of Building and Housing has been preparing a more comprehensive code for three years, which would significantly upgrade requirements for building energy efficiency. Although their promulgation has been delayed, certain components, such as the mandatory adoption of double-glazed windows and expanded wall and roof insulation became mandatory as of October 2008. Yet, these provisions do not address the energy inefficiency of the existing older buildings that so dominate the country’s urban and rural landscapes.

This dynamic has surely not been ignored by the legislature. For instance, the Energy Efficiency and Conservation Act 2000 has a defined purpose of promoting energy efficiency, energy conservation and renewable energy.¹⁵⁵ The law indeed moved the government to propose a national energy efficiency and conservation strategy which states that by

2016 all homes built before 1977 be retrofitted with cost-effective energy measures. In order to implement the strategy, however, it would be well to consider successful initiatives from other countries.

A variety of legislation has begun to emerge throughout the world to create incentives to improve energy conservation in existing structures. For example, the Danish Act to Promote Energy Savings in Buildings

2005 seeks to promote energy efficiency in all buildings by putting the issue on the table during sales.¹⁵⁶ Even small structures are required to attain an energy rating and draft an energy plan.¹⁵⁷ When houses are sold, house owners must make these plans available to buyers, allowing energy performance to become a meaningful consideration in purchasing decisions. Accordingly, when selling a building, the seller must make sure that buyers have access to and are aware of the energy rating and conservation plan prior to finalizing the terms of sale.¹⁵⁸ (A similar approach has successfully raised public awareness of radon in buildings in the US by requiring radon measurements as a standard element in the disclosure required of house sellers.¹⁵⁹)

¹⁵⁴ Building Regulations 2007 H1.3.2A (a-b). The Regulations recognize that New Zealand is divided into different regions according to climate conditions. The building performance index is set according to the specific conditions with a maximum allowable grade of 1.55 set for climate zone

3 with a 0.13 ceiling set in climate zones 1 and 2.

The US state of Alaska has linked its energy conservation requirements to house purchases through finances and mortgages. Favorable financing terms are offered to vendors if they purchase homes with a “five star rating or better”. More importantly, financing is specifically offered to low-income families who upgrade energy performance in existing homes.¹⁶⁰

The building code in Australia ultimately, is not unlike that of New Zealand’s but statutorily it has begun to address the problem of poor energy performance in existing structures more aggressively. After the enactment of the Act to Promote Energy Savings in Buildings 2005,¹⁶¹ the Australian building code now mandates energy efficiency in housing

– including roof, walls and floor resistance to heat transfer. States are required to comply with a National Home Energy Rating Scheme with a general goal of having all homes achieve a “five star” ranking pursuant to it. But the Act also offers homeowners a rebate for undertaking measures to improve energy performance.¹⁶²

New Zealand already has most of the critical regulatory infrastructure in place for upgrading the energy efficiency of its buildings. It should consider integrating measures like those highlighted above into existing building codes. Moreover, by using financing of homes as a point of leverage for improving the energy performance of existing buildings, it can significantly improve awareness and implementation of energy conservation measures in old structures with attendant reductions in GHG emissions. It would seem that energy-efficient construction and retrofitting is another example of a “no regrets” – “win-win” initiative that a market driven policy cannot guarantee.

Renewable Energy

The ban on new coal-fired electricity plants will of course help freeze GHG emissions from the energy sector. Meanwhile electricity utilities are likely to take full advantage of cap and trade systems to offset their emissions as well as improve their own energy efficiency. At the same time, the present legislative signals in New Zealand do not take advantage of the potential public support to develop alternative energy sources. Unlike several countries, New Zealand has wisely resisted pursuing a path of emission free energy from nuclear sources.¹⁶³ Ultimately, if alternative clean energy sources do not become available during the 10-year ban period, the aforementioned “security” exemption for coal-fired plants will surely be triggered as the political pressures to provide reliable

electricity to consumers will become intolerable.

The aforementioned Energy Efficiency and Conservation Act 2000 has encouragement of renewable energy as one of its primary objectives. The Act even establishes an Energy Efficiency and Conservation Authority (EECA) as a crown entity.¹⁶⁴ This offers a critical institutional basis for more aggressive initiatives. The EECA enjoys a mandate “the main body responsible for helping to deliver the government’s extensive energy efficiency agenda”.¹⁶⁵ And undoubtedly the 10-year ban on fossil-fuelled thermal electricity generation under the Climate Change (Emissions Trading and Renewable Preference) Bill will trigger expanded renewable energy initiatives in New Zealand at the macro-level.¹⁶⁶ It is not clear, however, whether the present normative framework is free from institutional complications and competing interests. Nor will present legislation necessarily expedite the progress which is so important to maintaining economic growth without compromising GHG emissions reduction goals.

For example, the Electricity Commission, established under the Electricity Act 1992 is motivated by a different and potentially conflicting mandate than the EECA.¹⁶⁷ Solar and wind energies are far more modular and decentralized than conventional energy sources. In several countries, electrical utilities and their government allies have squelched meaningful development of such alternative energy sources which were perceived as strategic threats. In order to avoid such a potential institutional clash, a Memorandum of Understanding was drafted between the Electricity Commission and the EECA.¹⁶⁸

It is not clear that solar powered electricity is the best strategic decision for New Zealand. Even now, photovoltaics are not considered to be cost-effective relative to other options. Moreover, New Zealand lacks natural conditions for optimal solar electrical generation. While there is considerable geographic variation, table 1 reflects the relatively modest sunshine in some areas of New Zealand compared to that available in other climates.¹⁶⁹

Aggressive efforts to promote photovoltaic roofs, such as the government programs and subsidies in Germany and Japan (see below) may have symbolic value, but these are expensive and produce a trivial percentage of national electricity.¹⁷⁰ And yet, the technology available for passive solar water heating, offers one example of solar energy that is clearly cost-effective. Unfortunately, progress in this area remains slow, belying legislative inadequacies. On the one hand, ostensibly the government has made solar water heating a priority including it as part of its second five-year Energy Efficiency and Conservation Strategy for New Zealand. The strategy envisions an additional 15,000 to 20,000 solar water heating systems installed by 2010, and calls for subsidies to expedite the transition to solar power systems.¹⁷¹ These can contribute

as much as 500 dollars towards the costs of installation.¹⁷² Participation in solar water heater installation courses are also subsidized, at half the cost.

In practice, the New Zealand Solar Industries Association (SIA) is the dominant stakeholder in the area. The Association offers a rare and encouraging case of cooperation between the sundry players in a diverse industry (manufacturers, importers and installers of solar water heating systems) who managed to organize themselves in a single agency.¹⁷³

The EECA works with the SIA to help develop the solar water heating industry. To ensure the technical integrity of local installations, the SIA drafted the Solar Water Heating Manufacturing and Installation Code

of Practice for New Zealand. In addition, an accreditation system was established to ensure that customers receive water heaters that meet industry standards.¹⁷⁴

Yet, these standards do not enjoy formal legal status and do not prevent unauthorized dealers from entering the market. Moreover, the New Zealand Building Code requires that prior to installation, all solar water heaters must receive a local government building consent. It is estimated that this bureaucratic hurdle adds an extra 10 percent to the actual cost of a solar heater, despite the fact that most solar water heaters utilize existing hot water cylinders within the building envelope. ¹⁷⁵

Other countries have been far more aggressive in ensuring the diffusion of solar water heating technologies. For example, almost 40 years ago, Israel decided to make the solar water heaters a standard part of residential and commercial buildings. The regulations preceded the “energy crisis” of 1973-74 but were adopted as an important step towards economic self-reliance. Regulations under the country’s Planning Building Law required that any building of eight stories or less contain a solar water heater system.¹⁷⁶ The regulations recognize the potential aesthetic problems associated with these facilities on roofs, and specify that they be concentrated together on the roofs and blend into the structure to the extent possible. Water tanks are to be white unless a planning commission specifies otherwise. It is important to note that the default assumption is that installation of the systems is standard procedure; intervention is required for exemptions or permission to change basic specifications.¹⁷⁷

As a result of the regulations, Israel came to lead the world in per

capita hot water heating from the sun. By 1995, solar-water heaters saved some 620 kilowatt hours nationally a year – approximately 3.2 percent of country’s total usage.¹⁷⁸

Promotion of wind-generated electricity may prove to be a far more logical strategy for New Zealand. While wind mills have been a source of energy for centuries, present technologies with two or three blade horizontal-axis systems show operational efficiency above 45 percent

– far greater than that of present coal technologies.¹⁷⁹ The costs associated with generation have also plummeted to 10 percent of what wind power cost a decade ago – making wind energy competitive with conventional sources of energy today.¹⁸⁰

It is important to stress that wind power has emerged as a major source of electricity in Europe due to the setting of clear, quantitative objectives and enabling legislation. More and more countries are setting ambitious statutory goals for wind-powered infrastructure. For instance in the United Kingdom, a goal was set for 10 percent wind power by the year 2010¹⁸¹ with legislation and tax incentives enacted to expedite the technological transition.¹⁸² While delays in the planning process will probably prevent its realization,¹⁸³ progress remains impressive. The US national energy strategy calls for 20 percent wind power (even as present levels hover around one percent).¹⁸⁴ For some countries, implementation is running ahead of schedule, with nine percent of power in Spain and seven percent in Germany coming from wind power. Indeed, industry reports a new wind turbine installation taking place every four hours world-wide.

The high German rates were achieved through the provision of 25 percent subsidies for investment in wind farms. As early as 1991, its Electricity Feed Law required suppliers to purchase electricity from small generators at 90 percent of the full domestic rate. The price was later raised as part of Renewable Energy Law of 2000, regardless of market price for conventionally generated electricity. The market was quick to

respond.¹⁸⁵ Aesthetics are generally considered to be one of the main obstacles in the planning process which delays implementation and discourages investment. By giving wind farms “preferred development status” under its planning law, Germany avoided some of the traditional delays.

Denmark has distinguished itself as the unquestioned world leader in producing electricity from wind, and so it is well to consider what legislation led to this unexpected result. Today more than 20 percent of Danish energy is generated by wind and the country has deemed

50 percent as its next step on the road to energy independence.¹⁸⁶ Like many countries, the process began with a law defining clear quantifiable medium-range objectives: a commitment in 1990 to reduce carbon emissions to 20 percent of 1998 levels by 2005.¹⁸⁷ A national strategy entitled “Energy 21” called for development of renewable energy so that by 2005 it would constitute 13-14 percent of total production. At the same time, Denmark was among the first country to call a moratorium on coal-fired power plants.

Like the German experience, requiring feed-in tariffs from electrical utilities was a critical component of the national strategy. This enabled the Danish energy programme to seriously engage its public and encourage their investment in wind facilities. Some 150,000 citizens have invested in wind turbines so that of the country’s 5,500 active wind turbines, 75 percent are owned by local co-operatives. It is little wonder that some 86 percent of the public expresses support for the government’s energy policies. (Germany followed with a similar policy so that today a third of its wind infrastructure is owned farmers, households, small businesses and co-operatives.¹⁸⁸) Economically, both countries have been rewarded for their conscientiousness. Danish wind turbines dominate the world market – with an 80 percent market share. This brings three billion Euros in foreign currency and provides employment for 20,000

^{Danish workers.}

Adopting such measures makes sense in New Zealand. As part of its new energy strategy, the government has endorsed a strategy that calls for 90 percent of its energy to come from renewable sources by

¹⁸⁵ While installation costs are uniform across the country, the actual tariffs paid by the German government are dependent on the level of wind farm performance. All generators receive a fixed price on installation in order to ensure a broad diffusion of facilities, and not only in areas with a natural advantage in terms of wind conditions. Prices are guaranteed for 20 years, although initial prices are being ratcheted down in order to encourage innovation and efficiency.

2050. To that end, recently the Government released the final New Zealand Energy strategy 2025.¹⁸⁹ As of the year 2005 less than three percent of New Zealand’s total power came from wind farms; if most of the proposed wind farms are actually implemented, that percentage will change present energy profiles for the better. Providing the kind of feed-in tarrifs and other economic incentives that have so changed the energy profiles of countries like Denmark would help ensure that even more ambitious clean-energy objectives are met.

In a country as scenic as New Zealand, conflicts between the twin environmental values of aesthetics and clean energy production are ineluctable. The Resource Management Act’s planning and consent process recognizes this and establishes “outstanding landscape” as a legitimate legal basis for objecting to wind farms. Yet, by engaging local communities in the planning process, the “pros” associated with clean energy can be better communicated. Spain has increased public support for wind farms by requiring them to invest a proportion of their profits into the local communities. New Zealand firms, such as Meridian Energy’s 136 wind turbine Central Otago’s Project Hayes, have begun to implement this approach, making grants to local medical and educational services. Yet, these benefits should be better communicated and the law should offer a clearer basis for compensating these companies.

Transportation Management

Given present technologies and current reliance on the internal combustion engine for everyday transportation, reducing the use of vehicles on New Zealand roads should be an integral part of an attempt to lower the nation’s overall GHG emissions. Present estimates suggest that while vehicles contribute some 15 percent to global GHG emissions, this proportion could triple over the coming decades if present transportation patterns and motor vehicle technologies do not drastically change.¹⁹⁰

The relative contribution of vehicular travel in New Zealand to the local GHG portfolio is remarkably similar: in 2005, 77.2 million tons of carbon dioxide equivalents or 15 percent of greenhouse gas emissions came from land transport – roughly two-thirds of which came from passenger vehicles.¹⁹¹ But transport is the fastest growing “sector” in the GHG inventory and present policies may need to be supplemented.

There may be no “wedge” where a “no regrets” justification for policy interventions is greater than that of reduced vehicular emissions, in particular from demand for management for traffic. Some 399 premature mortalities each year in New Zealand have been associated pollution from mobile sources.¹⁹² In cities, especially Auckland, gridlock and

congestion substantially impairs urban quality of life. Given the general dispersion of the population geographically, local vehicle ownership rates are high. In 2007, there were 2,775,717 privately owned cars in New Zealand, roughly a third of which are in the greater Auckland area.¹⁹³

^{This rate is higher than in most European countries.}

Reduction of GHG emissions can be achieved through two basic strategies: improved vehicle performance or demand management. Basic emission and fuel efficiency standards are important steps which have been adopted in a variety of jurisdictions. The recent dramatic rise in petrol prices has begun to influence preference for more efficient vehicles¹⁹⁴ and it can be argued that the market has provided a greater incentive for reduced fuel consumption than any direct carbon tax ever would have.

At the same time, there is a world-wide move to improve the fuel efficiency of new vehicles. Many countries, like the United Kingdom have adopted EU targets of upgrading the fuel efficiency in new cars by 25 per cent by 2009.¹⁹⁵ The stringency of these standards is likely to continue to increase. Because New Zealand has such a relatively small fleet of vehicles and no automotive industry to speak of, it is unlikely that domestic legislation would make a meaningful impact on the quality of available vehicles. Nonetheless, there is no reason why the increasingly efficient European performance levels cannot be imposed as import standards.

High Occupancy Vehicle Lanes

A full characterization of the numerous policy options associated with demand management is beyond the scope of this article. Among the more obvious is the expansion of High Occupancy Vehicle (HOV) Lanes, congestion fees for entrance into cities, carpool facilitation, subsidies and expansion of bicycle lanes and limiting urban parking, the first two of which will be briefly reviewed.

HOV lanes are specially designated motorway lanes on which vehicles can only travel if they contain more than two or three passengers.¹⁹⁶

^{buses. They encourage car sharing or public transport use, or both, by}

^{allowing users to reduce their journey times relative to single-occupant}

^{vehicles, particularly when the general purpose lanes are congested. This}

^{in turn reduces the number of cars on the network and this reduction}

Among their attendant benefits is expanded ride sharing and overall trip reductions. There are numerous ways to encourage HOV lanes. The most common is mandating their integration in major motorways either directly or through local authorities. For example, in Ontario, Canada, policy makers decided that 450 new kilometres of HOV lanes would ease local congestion. New legislation¹⁹⁷ and subsequent regulations¹⁹⁸ empowered the provincial police to enforce the two- passenger minimum standards.¹⁹⁹ The assumption is that HOV lanes should be established based on specific traffic patterns on the ground and that implementation should be site-specific.²⁰⁰ Accordingly, the Ontario Minister of Transportation is empowered to promulgate regulations pursuant to s154(1) of the Highway Traffic Act, s154(2) to determine the types of vehicles to whom the regulations apply.²⁰¹

Implementing lanes is not sufficient in and of itself. Thus Ontario has established a series of supplementary infrastructure improvements to ensure benefits to those who respond to the incentives and fill their car with more than one person. These include:

• Establishing continuous highway-to-highway ramps for HOV lane users to expedite transition from one highway to another for HOV lane vehicles;

• Creating special access lanes or ramps dedicated exclusively to

^{HOV use; and}

• Establishing special “carpool parking lots” close to highway interchanges facilitating carpooling among commuters.²⁰²

Many US states have also begun to aggressively expand HOV lanes and special, federal funding has been made available to this end. The federal government has been moderately supportive through legislation such as Title 23 of the United States Code of Federal Regulations that

defines carpool projects²⁰³ including passenger requirements for vehicles utilizing HOV lanes.²⁰⁴ Funding for their development is derived from the Federal-Aid Highway Fund, which was established by Congress to assist states in improving highways and developing special purpose projects.²⁰⁵

For almost forty years, the State of Washington has attempted to encourage carpooling, investing over a billion dollars in approximately

360 kilometers of HOV lanes.²⁰⁶ Local authorities are entitled to allocate any portion of highway funding for the creation of lanes for public transportation vehicles and HOV lanes “carrying no fewer than two

passengers”.²⁰⁷ Frequently, lanes are declared “HOV” for specific hours to reduce congestion, although if the ultimate goal is to reduce trips of vehicles and emissions, clearly, full-time lanes are preferable.²⁰⁸ Moreover,

Washington State legislation has moved municipalities to fill up HOV lanes through facilitating carpooling. For instance, over ten years ago, Whatcom County (Washington State) promulgated by-laws requiring employers with more than 100 workers arriving to work between 6:00 and 9:00 in the morning to prepare and implement programs that would reduce their employee “drive-alone” trips.²⁰⁹ A database of commuters was created to facilitate carpooling²¹⁰ with emergency rides and cash incentives provided for proven carpooling efforts that reduced fuel use and pollution.²¹¹ In its first year, over 5,000 residents registered 395,407 trips which ultimately saved 5,074.28 tons of CO2 from being emitted into the atmosphere. Since then, the state legislature has imposed a duty to prepare such initiatives among all local governments through the Commute Trip Reduction Efficiency Act. Municipalities with high levels of mobile source induced air pollution and congestion must implement plans to reduce single-occupant vehicle trips by 10 percent, and vehicle miles travelled by 13 percent by 2011.

^{Congestion Charges}

Placing a tax on vehicle travel into cities has proven to be a highly effective way for reducing congestion and trips. If set at an appropriate level, they can provide clear incentives to drivers to either delay trips, cancel them or opt for the cheaper alternative of public transportation. The most famous example of such an intervention involves the congestion charges imposed for entry of vehicles into London.

The United Kingdom has been a conscientious signatory to the Kyoto Protocol, setting its greenhouse gas reduction objectives to 20 percent below 1990 levels, a full 12 percentage points above the EU’s eight percent Kyoto obligation.²¹² To meet this goal, improving vehicle efficiency and reducing congestion have been identified as key components of a 10-year programme.²¹³ In 1998, a “White Paper” issued by the UK Ministry of Transport laid out a thoughtful strategy for encouraging public transport and reducing car usage.²¹⁴

With over 7.5 million residents (or more than 14 percent of the UK population), nowhere were traffic problems more acute than in London. The local government was granted broad authority to address its traffic pathology under the Greater London Authority Act 1999 (GLAA). The mayor is required to draft and implement a transportation programme consistent with the strategy articulated in the White Paper. Originally, London’s congestion charge was designed to improve traffic flow and mobility as its paramount objective. Yet, as global warming became a more salient issue, its “climate change” benefits were recognized and increasingly highlighted. The charge also sought to move drivers from single occupancy private cars to public transport or HOV alternatives.²¹⁵

Specifically, drivers in London are now required to pay £8 if they enter the 21 square kilometre circumference surrounding the heart of London between the hours of 7 am and 6 pm. This area is primarily commercial. Compliance is monitored through a complex CCTV camera system and a fine ranging from £60 to £180 is imposed on vehicles for non-payment.²¹⁶

exemptions are granted for large passenger vehicles holding over nine passengers and discounts provided for electric or alternative fuel cars.

From the position of revenue generation, the congestion charge has been deemed an unmitigated success. The system generates over

£240 million a year – prior to expenses.²¹⁷ The Act in its fourth Annex designates that the funds cannot be diverted for other general purposes. Rather money collected by the fee must be utilized to improve London’s public transportation system as well as its efficiency and accessibility. This “closed system” helps to assuage public concern or indignation at the new “tax”.

Of course the bottom line is the impact of the surcharge on traffic patterns themselves. According to local evaluation, with a 70,000 trip reduction per year, congestion has dropped by a full 30 percent. Among the drivers who make up the 70,000 trip reduction, 50 to 60 percent report that they have simply opted to travel via public transportation. Estimates suggest that the modal shift has led to a 20 percent drop in carbon emissions from the area’s transport sector.²¹⁸ A proposed increase in the congestion fee for high polluting vehicles that would have increased the fee to £25 per trip was recently abandoned. Following a legal challenge by the Porsche car manufacturer, new London mayor Boris Johnson abandoned his predecessor ’s proposal, which would have made visits to London in cars with high carbon emissions, five times more expensive than they presently are.²¹⁹ Nonetheless, the London experience may be highly relevant for a city such as Auckland.

Perhaps the most long-term, ambitious transportation driving-fee program can be found in Singapore where since 1970, planners have followed a Land Transportation Strategy.²²⁰ Because of the country’s diminutive dimensions, its subsequent legislation has been a model for Europe as well as the London initiative. Of particular interest is the country’s “Electronic Road Pricing” which since 1998 has served to reduce vehicle trips. Electronic sensors read the licence plate numbers when they enter a priced zone and charges vehicle owners accordingly.²²¹

Fees are set to reflect the contribution to traffic congestion (time of day) as well as to the vehicle class, rather than according to the number of passengers travelling. Fees produce a profit of $40 million (US)

annually,²²² which is estimated to be three times higher than the cost of road maintenance.²²³

Reports from Singapore about the effectiveness of the policy (or the elasticity of passenger preferences) are also encouraging. Following the imposition of the fees, the number of vehicles has dropped by almost 20 percent (from 270,000 to 235,000) sparking a rise in car pooling.²²⁴ As early as the 1970s data showed that beyond changing the times of their travel, many drivers shifted to public transport, which saw a sudden increase to

^{46 percent of all trips by 1974. By today, that rate has increased to over}

^{60 percent public transport usage. While there have not been estimates}

^{of the net carbon equivalent reductions due to the forgone emissions,}

^{clearly congestion fee programs can provide a meaningful cut in the}

^{contribution of traffic to overall GHG burden.225}

These measures are not new to New Zealand. Indeed HOVs are already functioning in a very limited area of Auckland’s North Shore. Under the Land Transport Road User Rules 2004 “Transit Vehicle Lanes” are defined as: “a lane reserved for the use of passenger service vehicles, cars carrying not less than the number of persons (including driver) specified on the sign, cycles and motorcycles”. Rule 2.2(1) proscribes driving in these lanes for vehicles which do not meet the sign’s requirements. The Local Government Act 2002 authorizes the promulgation of bylaws to facilitate the establishment of transit vehicle lanes.²²⁶

At present, the government has no immediate plans to adopt congestion fees. There is a consensus that traffic congestion constitutes an economic externality. For example, New Zealand Round Table, estimates that road congestion is costing Auckland around $750 million per year.²²⁷ When the costs of the carbon emissions reduction credits that will need to be purchased to offset these GHG emissions are figured in, the overall costs are surely higher. And with projected demographic increases of 1.5 percent per annum forecasted, the number of car trips is expected to rise proportionally. While there have been isolated calls for legislative reform

to utilize economic instruments to control traffic demand,²²⁸ present policies appear to prefer to accommodate the increase in fleet size, rather than to manage traffic demand and reduce GHG emissions.²²⁹

VI. Conclusions

New Zealand is paying an economic price for its relatively high level of environmental performance in 1990. Had it not had such highly developed hydroelectric power during the “base-line year”, finding ways to reduce GHG emissions to international expectations would be far easier. The targets set under the Kyoto Protocol and the new 2009 standards anticipated under the UNFCCC place an unfortunate price-tag on the country’s steady economic growth. These circumstances constitute a new reality, and the level-headed decision to ambitiously move forward with new legislation is a good one. Ultimately, the resulting reduction in GHG gases will improve quality of life locally, beyond contributing to global climatic stability. The cap and trade statutory solution which appears to be the current government’s response constitutes both a worthy and creative response that should be implemented expeditiously. At the same time, legislators should not see passage of the Climate Change (Emissions Trading and Renewable Preference) Bill as the last word on the subject.

There are no shortage of additional regulatory interventions that can save the country money and move it more expeditiously towards its international commitment. As the least costly reductions will be made initially, future additional reductions will have higher marginal associated costs. Hence, it is well to take advantage of promising opportunities and adjust accordingly. This is the climate change policy equivalent of picking the proverbial “low hanging fruit”.

This article has briefly looked at four possible areas of legislation and regulations where other countries appear to have made progress. But of course there are many other categories of carbon “wedges” which might provide reductions in emissions and long-term economic benefits. As GHG emissions are so linked to individual behavior and because millions of individual decisions contribute to the overall energy demands, climate change policy is an area where legislation needs to be particularly creative and sensitive to sociology, economics and values.

For over a decade, New Zealand was the only country in the southern
