U.S. moves to exit global climate bodies, drawing sharp rebukes

The United States is moving to withdraw from the United Nations Framework Convention on Climate Change and the Intergovernmental Panel on Climate Change, reopening a deep rift between Washington and the international climate system it helped create more than three decades ago. The decision, taken under President Donald Trump, marks one of the most far-reaching retreats from multilateral climate cooperation by any major economy.

The withdrawal forms part of a broader pullback from international institutions. A presidential memorandum orders an immediate halt to U.S. participation and funding for 66 global bodies judged incompatible with American interests, security and sovereignty, according to U.S. officials.

UN warns of a “self-inflicted setback” 

The response from the UN was unusually blunt. Simon Stiell, the UNFCCC’s executive secretary, described the move as a strategic own goal, warning that it would ultimately damage the U.S. economy, jobs and living standards, particularly as climate-driven extreme weather and insurance costs accelerate.

On the same day, Washington also announced it was withdrawing from the IPCC and cutting contributions to the Green Climate Fund, the UNFCCC’s main financing vehicle for climate mitigation and adaptation in developing countries.

EU Climate Commissioner for Climate Wopke Hoekstra described the move as “deeply regrettable,” noting that the United States is still the world’s largest economy and its second-largest source of emissions. 

He added that the UNFCCC remains central to international cooperation on cutting emissions, adapting to climate impacts and measuring progress, and said Europe would continue to back the framework both politically and financially.

Sovereignty over multilateralism

The Trump administration has framed the withdrawals as a defence of national sovereignty against what it characterises as intrusive global governance and ideologically driven climate policies. Climate institutions are not the only targets. International reporting indicates the disengagement extends to UN bodies linked to development and gender equality, including the United Nations Population Fund and other affiliated agencies.

What’s at stake for the EU

Adopted in Rio de Janeiro in 1992, the UNFCCC underpins the rules-based system on which EU climate policy is built, from emissions transparency and collective targets to climate finance for vulnerable countries. 

A U.S. exit weakens that framework at a critical moment, shifting more diplomatic, financial and political weight onto Europe to keep global cooperation credible. For Brussels, this is not a symbolic rupture but a structural challenge that risks fragmenting the climate consensus the EU has invested in for more than a decade.
