The U.S. Environmental Protection Agency will maintain the current greenhouse gas (GHG) emissions standards for cars and light trucks from model years 2022 to 2025, according to Gina McCarthy, the agency's administrator.
Automakers should be able to meet the standards with existing technologies to reduce GHG emissions on new light-duty cars and trucks, McCarthy said.
"At every step in the process, the analysis has shown that the greenhouse gas emissions standards for cars and light trucks remain affordable and effective through 2025, and will save American drivers billions of dollars at the pump while protecting our health and the environment," McCarthy said in a statement.
By the 2025 model year, average consumer fuel economy sticker values should reach 36 miles per gallon across their model range on a sales-weighted basis. Automakers would need to raise their fuel economy 10 mpg above the current average.
The announcement comes as part of the Midterm Evaluation process that was established with the 2012 final greenhouse gas emissions standards for model years 2017 to 2025. This decision follows the Proposed Determination issued by the EPA administrator in November 2016, as well as the Draft Technical Assessment Report, issued in July of 2016.
