摘要: |
The data supporting this report were obtained by the U.S. Environmental Protection Agency (EPA), directly from automobile manufacturers, in support of EPA’s greenhouse gas (GHG) emissions and the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) Corporate Average Fuel Economy (CAFE) programs. These data have been collected and maintained by EPA since 1975, and comprise the most comprehensive database of its kind. This report (the “Trends report”) has been published annually since 1975 to summarize trends in EPA’s best estimate of real world tailpipe CO2 emissions and fuel economy, and associated technologies. While based on the same underlying data, the Trends report does not provide compliance values. |
