Greenhouse Gas Emission Standards for Light-Duty Automobiles: Status of Early Credit Program for Model Years 2009-2011

The Environmental Protection Agency (EPA) Greenhouse Gas (GHG) program, which requires compliance with progressively more stringent GHG standards starting with the 2012 model year and concluding with the 2025 model year, includes certain flexibilities designed to provide sufficient lead time for manufacturers to make technological improvements and to reduce the overall cost of the program, without compromising overall environmental objectives. One of these flexibilities is an optional program that allowed manufacturers with superior greenhouse gas emission reduction performance to generate credits in the 2009-2011 model years, prior to the 2012 model year (the “early credits program”). Because this is an optional program, without any compliance implications in these early model years, only those manufacturers who achieved emissions performance beyond that required by existing California or Corporate Average Fuel Economy (CAFE) standards chose to provide data; thus the data does not include information for all manufacturers. The first opportunity to review data from all manufacturers will be later in the 2013 calendar year, when the EPA receives compliance reports for the 2012 model year. While there are factors that could lead to revisions to the early credits data (e.g., future credit transactions between manufacturers), the data presented in this report is believed to be stable as of the date of publication. This report summarizes and explains the credits reported by each manufacturer in the 2009-2011 model years, as well as explaining the options for earning and using early credits.
