President Donald Trump has withdrawn the United States from the United Nations Framework Convention on Climate Change (UNFCCC), a foundational climate treaty. This decision is part of a broader pullout from approximately 66 global organizations and treaties deemed contrary to U.S. interests by the White House.

• The UNFCCC, adopted in 1992, is the parent treaty for major international climate agreements, aiming to reduce greenhouse gas emissions.
• The EU climate chief Wopke Hoekstra condemned the withdrawal, calling it "regrettable and unfortunate" given the U.S. is the world's largest economy and second-largest emitter.
• The withdrawal could face legal challenges, as Jean Su, a senior attorney for the Center for Biological Diversity, argues it's illegal for the President to unilaterally withdraw from a treaty requiring two-thirds Senate approval.
• The Trump administration also directed withdrawal from the Intergovernmental Panel on Climate Change and other climate-related organizations.
