A bill introduced last week by a Republican Michigan congressman would prevent the Environmental Protection Agency from implementing the strictest auto emissions rules yet.
The EPA introduced the rules in April as the Biden administration aims to curb harmful emissions by pushing for greater electric-vehicle adoption. The restrictions would affect 2027 to 2032 models, resulting in 67% of light-duty vehicle sales being electric by the 2032 model year.
Rep. Tim Walberg’s bill would stop the new rules from being enforced and revise the Clean Air Act to bar required technology and limited supply of vehicles with certain types of engines.
The rule tightening has attracted criticism from both sides of the aisle, with Republicans saying the new rules are too strict and Democrats saying they’re not strict enough. Industry advocacy group the Alliance for Automotive Innovation has said they would give Chinese automakers an opportunity to leave the U.S. behind.
