The Trump administration is expected to roll back Obama-era Environmental Protection Agency standards on greenhouse gas emissions, which were imposed as part of former President Barack Obama's efforts to fight climate change. EPA chief Scott Pruitt is expected to frame the plan to ease fuel economy standards for U.S. vehicles as an effort to ensure the production of more affordable trucks, vans, and sport utility vehicles for American buyers. "This is certainly a big deal," said Robert Stavins, director of the Harvard environmental economics program. "The result will be more gas-guzzling vehicles on the road, greater total gasoline consumption, and a significant increase in carbon dioxide emissions."
