Summary:
On 10 June 2025, a climate case was filed in the Wellington High Court in Aotearoa New Zealand by the organizations Lawyers for Climate Action NZ and the Environmental Law Initiative (ELI). The case challenges decisions relating to the country’s first (2021-2025) and second emissions reduction plans (2026-2030), including the second plan’s offsetting-led approach, which prioritizes reforestation measures over emissions reductions.
Regarding the first emissions reductions plan, the plaintiffs challenge the ex post cancellation of various projects and actions set out in that plan by the current Government. They argue that domestic legislation, and particularly the Climate Change Response Act, “imposes guardrails on government’s ability to change and cancel climate policies on the fly.” They also challenge the absence of adequate public consultation concerning the changes.
Regarding the second emissions reductions plan, they allege that the Minister of Climate Change is under a legal duty to ensure that emissions budgets are met, which in turn requires the preparation and publication of emissions reductions plans setting out policies and strategies for meeting the emissions budget. The second emissions reduction plan has a wide uncertainty margin, and projects that New Zealand won’t achieve its 2035 target, meaning that according to the plaintiffs it is inadequate, unlawful and too limited in its modeling, as well as taking “an unrealistic and inadequate approach to risk management, relying on a ‘wait and see’ approach it calls ‘Adaptive Management'”. The plaintiffs further challenge the offsetting-led approach of the second emissions reductions plan, and more specifically the decision to prioritize reforestation measures over emissions reductions. They argue that this plan “proceeds on a fundamental error of fact – that forestry offsets and reductions are fungible, when that’s not the case”, and that it does not suffice to comply with the country’s obligations under the Paris Agreement.
