Global Climate Ambition Falters Ahead of COP30 in Brazil as Key Nations Delay Emissions Pledges

Countries Dither on Crucial Climate Pledges for COP30

In the lead-up to the 30th United Nations Climate Change Conference (COP30), scheduled for November 10-21, 2025, in Belém, Brazil, a significant number of countries are reportedly delaying the submission of their updated Nationally Determined Contributions (NDCs). These NDCs are national climate action plans, central to the Paris Agreement, outlining how each country intends to reduce greenhouse gas emissions and adapt to climate change. They are meant to be updated every five years with increasing ambition, with the current round setting targets for 2035.

As of mid-September 2025, only a fraction of the 195 signatory nations have submitted their updated NDCs, with figures ranging from 29 to 34 countries. This widespread delay, particularly among major emitters, casts a shadow over the prospects for ambitious outcomes at COP30 and raises concerns about the world's collective ability to limit global temperature increase to 1.5°C. Current projections based on existing pledges indicate a trajectory towards a 2.6-3.1°C rise.

EU Bloc Struggles for Consensus on 2035 Targets

The European Union (EU), historically a leader in advocating for stringent climate action, is among the blocs yet to finalize its updated NDC. The 27-member bloc is reportedly facing internal disagreements, preventing a consensus on its 2035 emissions reduction target. Sources indicate that some key member states, including France and Germany, have expressed a preference to postpone a vote on the matter. Despite these internal challenges, there is an expectation that the EU will announce its updated NDC before the commencement of COP30 on November 10. The EU's current commitment aims for a 55% reduction in greenhouse gas emissions by 2030 compared to 1990 levels, with a proposed 90% net emissions reduction by 2040.

Brazil Urges Greater Ambition Amid Geopolitical Headwinds

As the host nation, Brazil has intensified its calls for countries to submit strengthened NDCs. André Corrêa do Lago, Brazil's COP30 President-designate, emphasized the critical role of NDCs, stating they 'represent the vision of our shared future' and are 'vehicles of cooperation'. The United Nations had set a September deadline for the submission of these plans to allow for the compilation of a 'synthesis report' that would assess global progress ahead of the conference. However, geopolitical complexities, including the Russia-Ukraine war and the rise of certain political ideologies, are cited as factors diverting international attention and resources away from climate objectives.

The upcoming COP30 conference in Belém is poised to be a pivotal moment for global climate governance, with the urgency for concrete, ambitious commitments underscored by the current delays in NDC submissions.
