Briefing: US states sue Trump EPA over decision to repeal bedrock climate finding

On March 19, 2026, a coalition of 24 states initiated legal action against the Trump EPA regarding the repeal of the endangerment finding, which classified greenhouse gases as a threat to public health.

The lawsuit argues that this rescission was illegal and poses significant risks to environmental and public health standards.

This case highlights the ongoing tensions between state-level environmental regulations and federal policy decisions, particularly in the context of climate change mitigation efforts.
