The Trump administration has taken steps to weaken federal regulations on vehicle emissions and fuel efficiency, reversing policies that had allowed California to enforce stricter environmental standards. The moves include repealing EPA rules targeting greenhouse gas reductions and eliminating the state’s authority to set its own emissions requirements. Environmental advocates warn the changes could lead to higher pollution levels and reduced efficiency standards for new vehicles. Critics argue the rollbacks prioritize industry flexibility over climate protections.
