A group of 23 states and 17 cities and counties have filed a lawsuit against the Trump administration for its decision to repeal the 2009 'endangerment finding' that recognized greenhouse gases as a threat to public health. This ruling provided the legal basis for emissions regulations, and its repeal is seen as an attempt to prioritize industry interests over environmental concerns.

Why it matters

The lawsuit represents a broader struggle over the future of climate change policies in the United States. With the Trump administration consistently downplaying the severity of the climate crisis and rolling back environmental protections, this legal challenge is a crucial step in holding the federal government accountable for its responsibilities in addressing the climate emergency.

The details

The lawsuit is a direct response to the Trump administration's decision to scrap the 2009 'endangerment finding' made under the Obama administration. This ruling provided the legal basis for emissions regulations, and its repeal effectively undermines the foundation of US climate policies. The Environmental Protection Agency has defended its decision, claiming the lawsuit is politically motivated, but critics argue this move is an attempt to prioritize industry interests over public health and the environment.

  • The lawsuit was filed in April 2026.
