EPA, DOT, and California align time frame for CO2 standards

  • 03-Feb-2011 05:21 EST

The U.S. Department of Transportation (DOT), the U.S. EPA, and the state of California announced a single time frame for proposing fuel-economy and greenhouse gas standards for MY2017-2025 cars and light-duty trucks. Proposing the new standards on the same time frame (by Sept. 1, 2011) signals continued collaboration that could lead to an extension of the current National Clean Car Program, providing automakers certainty as they work to build the next generation of clean, fuel-efficient cars. In April 2010, DOT and EPA established greenhouse gas emissions and fuel economy standards for MY2012-2016 light-duty cars and trucks. In the fall of 2010, California accepted compliance with these federal GHG standards as meeting similar state standards as adopted in 2004, resulting in the first coordinated national program. The standards require these vehicles to meet an estimated combined average emissions level of 250 g of carbon dioxide per mile in MY2016, which is equivalent to 35.5 mpg. In May 2010, President Obama announced that EPA, DOT, and California would begin working together to assess the performance and costs of a variety of technologies that could be available in MY2017-2025 as the first step in possibly extending the current national emissions and fuel economy standards. The three agencies completed an interim technology assessment and have since funded additional research critical to future rulemaking.
