EPA Rollbacks Face Climate Litigation topic image

Multiple lawsuits are challenging Trump EPA rollbacks of climate and air-pollution protections, especially mercury standards for coal plants and the 2009 endangerment finding that underpins federal greenhouse-gas regulation.

The pattern is legal resistance to federal deregulatory action, with public health and tribal plaintiffs arguing the rollbacks weaken long-standing protections.

The story is reframed more narrowly around lawsuits against Trump EPA attempts to undo climate and air-pollution protections, with the endangerment finding now elevated as a central target alongside mercury standards. The latest version also highlights a broader plaintiff coalition and a more explicit legal clash over EPA authority under the Clean Air Act and Supreme Court precedent.
