Environmentalists Urge Biden to Toughen Auto Emission Proposal

  • Regulations call for 52 miles per gallon fleet average by 2026
  • Environmental groups say rules should go even further

Environmental groups are urging President Joe Biden to floor it on his plans to place higher limits on greenhouse gas emissions from cars and trucks as some carmakers argue the current proposals are good enough. 

The Environmental Protection Agency announced plans in August to mandate fleet-wide vehicle mileage of 52 miles (84 kilometers) per gallon by 2026, up from 40 mpg this year. The EPA has said its proposal would result in a 10% reduction in vehicle emissions in model year 2023 and then a 5% greater emissions reduction improvement each year after through 2026.
