The Trump EPA's repeal of climate rules, from power plants to cars

Active · last development Sep 13, 2026: “EPA eliminates rule that limits planet-warming greenhouse gas emissions from power plants”

What this arc covers

The Trump administration's rollback of federal climate and pollution rules under EPA Administrator Lee Zeldin: his pledge to undo dozens of regulations, the repeal of the 'endangerment finding' that underpins climate regulation, announced in 2025 and completed in February 2026, and the lawsuits by states, cities and health groups against it, the repeal of limits on greenhouse gas emissions from power plants, the weakening of soot, vehicle mileage, 'good neighbor' smokestack and 'forever chemical' drinking water rules, the effort to narrow the wetlands rule, and the fight with California and other states over their own climate and vehicle emissions rules.
