This annual report (often referred to as the “Trends” report) is the authoritative reference on new light-duty (or personal) vehicle carbon dioxide (CO2) emissions, fuel economy, and powertrain technology trends in the United States. These vehicles include passenger cars, sport utility vehicles, minivans, and all but the largest pickup trucks and vans. This report uses the most comprehensive database of its kind, both because it is comprised of detailed new vehicle test data provided, under statute, to EPA by automobile manufacturers, and because the database has been rigorously maintained since 1975. Since major methodological changes are generally propagated backwards through the historical database in order to maintain the integrity of long-term trends, this report supersedes previous versions in the series and should not be compared to past reports.
