The EU needs to update its Nationally Determined Contribution (NDC) to the Paris Agreement by September 2025. This extended deadline allows the United Nations climate secretariat enough time to assess the collective effect of all national climate plans, relative to the targets under the Paris Agreement, before the start of the COP30 climate change conference in Belém, Brazil, in November 2025. The EU's NDC is formally adopted by the Council of the EU. The third NDC will have a time horizon of 2035, and is therefore linked with the EU climate target for 2040, which is to be adopted as an amendment to the European Climate Law under the Ordinary Legislative Procedure.
