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 will hinder efforts to combat climate change, while supporters claim they reduce burdens on automakers and consumers. The shift marks a significant reversal in long-standing policies aimed at reducing pollution from transportation.
