The New Zealand Government has announced a legal change aimed at providing greater certainty in climate change law by preventing tort-based lawsuits that seek damages for climate-related harm caused by greenhouse gas emissions. The move involves amending the Climate Change Response Act 2002 to ensure that courts cannot hold individuals or businesses liable in civil tort claims for climate change impacts linked to emissions.
Officials stated that the decision is intended to create a clearer and more stable legal framework for businesses and investors. The government argues that predictable legal conditions are essential for economic growth, investment confidence, and the effective functioning of existing climate policies such as the Emissions Trading Scheme (ETS), which already regulates emissions at a national level.
The government also emphasized that climate change is a complex global issue that should be managed through national policy frameworks rather than through individual court cases. It argued that tort law is not well suited to addressing systemic environmental challenges involving widespread social, economic, and scientific factors, and that litigation could undermine consistency in climate governance.
Under the proposed amendment, existing and future court proceedings would be unable to establish liability for climate damage claims based on emissions. However, officials clarified that this change would not affect existing obligations under New Zealand’s climate policies, including compliance requirements under the Emissions Trading Scheme. Businesses will still be required to meet their legal emission reduction responsibilities.
The decision comes amid ongoing debates in New Zealand and internationally about climate litigation, where courts are increasingly being asked to determine responsibility for climate-related harm. Legal experts note that such cases have raised complex questions about the role of private law in addressing global environmental challenges and the boundaries between judicial action and government policy-making.
Overall, the government says the reform is intended to maintain coherence in climate regulation, reduce legal uncertainty, and ensure that climate policy remains primarily a matter of legislative and executive decision-making rather than court-based liability claims.
