The administration’s latest move significantly weakens previously established fuel economy targets designed to reduce greenhouse gas emissions and dependence on fossil fuels. Critics argue that this rollback could lead to higher carbon emissions and undermine global efforts to combat climate change. Automakers stand to benefit in the short term, with less stringent regulations allowing for cost-cutting on fuel-saving technologies, but environmental groups warn of long-term consequences for public health and global warming trends.

Key changes include:

  • Lower annual mileage efficiency goals for passenger vehicles.
  • Extended timeline giving manufacturers more flexibility.
  • Suspension of penalties for missed targets during certain periods.
