The Trump administration pulled the rug out from underneath US federal climate policy in February, when the Environmental Protection Agency (EPA) overturned the landmark 2009 “endangerment finding”. Now, the official policy of the US government holds that greenhouse gases do not pose a risk to human health.
The move has opened a new frontier for Donald Trump to govern without being constrained by evidence or in a manner that represents the majority of Americans, who support pro-climate policies. It also follows a year in which the US president and his allies have hollowed out American climate leadership.
Since taking office, Trump and his allies have rolled back clean air standards for almost anything with a tailpipe or smokestack. In January 2026, they even instructed the EPA to stop estimating the value of lives saved in the agency’s cost-benefit analyses for new pollution rules. This could lead to looser controls on pollutants from industrial sites across the country.
