The Trump administration has weakened key environmental regulations by rolling back federal fuel economy standards and repealing EPA rules targeting greenhouse gas emissions. The moves also eliminate exemptions that previously allowed California to enforce stricter vehicle emissions standards than the rest of the country. Critics argue the changes could lead to higher pollution levels and reduced efforts to combat climate change. Supporters claim the regulations were overly burdensome on automakers and consumers.
