Overview
- On Feb. 12, the administration officially nullified the scientific–legal finding that allowed the EPA to regulate six greenhouse gases.
- The step threatens current and future limits on emissions from vehicles, power plants, oil and gas wells, and other industrial sources.
- Environmental groups and officials in states including California and Wisconsin have announced lawsuits to block the rollback.
- The White House frames the change as economic relief, citing projected $2,400 savings per light vehicle and claims of trillions in avoided rules, which scientists contest.
- Barack Obama and climate researchers warn the reversal weakens public health protections and U.S. climate action, as international outlets describe a major setback.
