Summary

The EPA is reconsidering its 2009 decision that greenhouse gases endanger public health and is reviewing vehicle emission standards that were designed to combat climate change. The agency is extending the deadline for people to submit comments on whether these protections should be weakened or remain in place.

Key Points

  • 1The EPA is reviewing whether to reverse its 2009 finding that greenhouse gases (like carbon dioxide) harm public health and the environment
  • 2Vehicle emission standards that limit pollution from cars and trucks could be changed or eliminated as part of this review
  • 3The public has more time to submit comments supporting or opposing these potential changes before the EPA makes a final decision
  • 4This affects car manufacturers, environmental groups, climate advocates, and drivers concerned about pollution and climate change
  • 5The outcome will determine how strict pollution rules are for new vehicles sold in the United States going forward
