Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends: 1975 Through 2009

This report, published in November 2009, provides data on the fuel economy, carbon dioxide (CO2) emissions, and technology characteristics of new light-duty vehicles (cars, minivans, sport utility vehicles, and pickup trucks) for model years 1975 through 2009.  CO2 emissions data are included in this report for the first time this year. For model year 2009, EPA projects average real-world CO2 emissions to be 422 grams per mile and fuel economy to be 21.1 miles per gallon (the fuel economy values in this report are those that EPA provides to consumers, and are lower than the fuel economy values used for compliance with CAFE standards). These are preliminary estimates, as the 2009 estimates are based on pre-model year production projections provided by automakers to EPA and are much more uncertain than most years due to turmoil in the automotive market. The model year 2008 values are 424 grams per mile CO2 emissions and 21.0 miles per gallon. This report confirms that average CO2 emissions and fuel economy have improved each year beginning in 2005, are at their most favorable levels since 1991, and represent about a 9 percent improvement since 2004. This reverses a long-term trend of worsening CO2 emissions and fuel economy since 1987.
