EPA Announces Plans to Update NOx, Greenhouse Gas Emissions Standards

摘要

The U.S. Environmental Protection Agency announced on August 5 plans to reduce greenhouse gas emissions and other air pollutants from heavy-duty trucks over the next three years. The EPA said in a statement that by December 2022, it will propose and finalize new stringent emissions standards to reduce nitrogen oxide pollution from trucks beginning in model year 2027. The existing federal NOx standard has not been changed for two decades. The agency said a second rule would set "more robust greenhouse gas emission standards" for new heavy-duty vehicles sold as soon as model year 2030 and beyond.
