(1) It is a guiding principle of this Act that a decision, policy, program or process should be based on—
(a) careful evaluation of the best practicably available information about the potential impacts of climate change to avoid, wherever practicable, serious or irreversible damage resulting from climate change; and
(b) an assessment of the consequences of each of the options in making a decision having regard to the risks of each of those options; and
(c) managing and allocating the risks associated with the potential impacts of climate change in a manner that is easily seen and understood and endeavouring to achieve best practice.
(2) It is a guiding principle of this Act that a decision, policy, program or process should not rely on a lack of full scientific certainty as a reason to postpone appropriate measures to prevent serious or irreversible loss or damage as a result of climate change.
