EU trade complaint puts New Zealand's climate promises to the test

A Dutch environmental group, Both ENDS, lodged a complaint with the European Commission's Single Entry Point on 29 September 2026. It says New Zealand is not meeting its climate commitments under its free trade agreement with the European Union. RNZ

According to Both ENDS, it was the first climate complaint under the EU's trade enforcement system. Both ENDS

The complaint is backed by New Zealand climate activists Mike Smith and Jane Kelsey. Greenpeace Aotearoa is a co-sponsor. The complainants say they want New Zealand to comply, not to stop trade.

The case centres on the Trade and Sustainable Development chapter of the EU-New Zealand deal. That chapter includes promises not to weaken environmental protections and to meet Paris Agreement commitments.

The legal test

The agreement says each side must "effectively implement the UNFCCC and the Paris Agreement, including nationally determined contributions commitments". NDCs are the individual emissions-cutting pledges each country files under Paris. It also says each side must "refrain from any action or omission that materially defeats the object and purpose of the Paris Agreement". RNZ

The complaint names three concerns. They are weaker targets for biogenic methane, the gas largely from livestock, removal of agriculture from the Emissions Trading Scheme, the system that prices greenhouse gas emissions, and law changes around the right to sue polluters for damage.

It also says the Government has no credible plan to meet its targets. It points to an estimated shortfall of 84 million tonnes of emissions. RNZ

The deal was signed on 9 July 2023 and came into force on 1 May 2024. The Government said at the time it held legally enforceable commitments on climate action, the environment, labour standards and gender equality.

University of Canterbury professor Bronwyn Hayward called it a "high-stakes, very serious landmark case" that trade partners around the world would watch. She said she was deeply concerned the Government had put the country's reputation and trade at risk.

University of Waikato professor Al Gillespie said the United Kingdom and members of the CPTPP trade agreement would watch with interest.

The political response

Trade Minister Todd McClay rejected the claim. He said it was "not for overseas countries, organisations or lobby groups to tell New Zealand how to meet its obligations".

McClay debated the question with Green Party agriculture spokesperson Steve Abel at a rural issues debate organised by agriculture sector groups in Waikato. The debate was held at Mystery Creek near Hamilton, before about 350 people. It was run in partnership with Federated Farmers and hosted by Heather du Plessis-Allan as a special election debate on issues important to rural New Zealand.

At the debate, McClay said New Zealand is meeting its obligations and will reach net-zero greenhouse gas emissions by 2050 under the Paris Accord. He said it is for the New Zealand Parliament and Government to decide how to meet those obligations.

Abel said the Green Party is not part of the Both ENDS complaint and does not support it. He said he had warned the Government in Parliament that its policies risked breaching the EU deal. He said New Zealand had failed its promise not to go backwards on environmental protections, which created the risk of a trade complaint.

The Greens have separately said Government support for fossil fuel companies likely breaches New Zealand's trade deal with the United Kingdom. They cited a Lawyers for Climate Action report. That claim is outside the Both ENDS filing, but it adds pressure on the Beehive over trade and climate.

The broader context here is one trade officials will know well. The EU-New Zealand deal was promoted in Brussels and Wellington as a model for enforceable green rules, with zero tariffs on green goods and regular joint checks on how it is working. A Single Entry Point complaint does not suspend trade discounts on its own. It starts a process of assessment, talks and possible dispute settlement.

In my view, the test for Wellington is about process as well as policy. Ministers will need to show methane targets and ETS coverage fit within the pledged emissions path and do not undermine the core aim of Paris. Other trading partners will look closely at how the Commission handles the complaint. The UK point counts for the same reason. If the EU rules are enforced, it will shape what is expected under other deals.
