Emissions Data
Emissions data and test results from the U.S. Department of Energy's extensive light-duty alternative fuel vehicle emissions testing program results are available in the September 1999 report, Light-Duty Alternative Fuel Vehicles: Federal Test Procedure Emission Results, which has been divided into sections that can be downloaded as Microsoft Excel files or viewed as Adobe Acrobat PDFs.

Emissions data from the various vehicles tested are organized by fuel. Separate files contain data from the FTP tests and the detailed hydrocarbon speciation analysis.
