The Trump administration has taken steps to weaken federal regulations on vehicle emissions, including rolling back fuel economy standards and repealing EPA rules aimed at reducing greenhouse gases. The move also removes exemptions that allowed California to enforce stricter emissions standards than the national average. Environmental advocates warn the changes could undermine progress in cutting pollution, while industry groups argue the adjustments will ease compliance burdens. Critics question whether the shift aligns with long-term climate goals or prioritizes economic flexibility over environmental protections.
