U.N. report: U.S. climate pollution rose sharply last year

The U.N. Environment Programme's Emissions Gap report, released Wednesday, says U.S. emissions rose sharply in 2025, far more than any other major economy, while global emissions were roughly flat. It links the U.S. rise to growing electricity demand, partly from data centers, and policies that favor fossil fuels. It says current policies put the planet on track for about 2.8°C of warming this century. A U.S. statement in the report says the country does not endorse or agree with its analysis or conclusions.
