What You Can Do
Green Vehicle Guide
This Web site will help consumers make more environmentally-informed choices when purchasing a vehicle. The Green Vehicle Guide lists pollution levels for all model years from 2000 through the present for passenger vehicles sold in the United States. Consumers can select a vehicle model, determine how clean it is relative to other vehicles, comparison shop for similar vehicles, and choose the cleanest vehicle that meets their needs. For more information, read this fact sheet: Green Vehicle Guide (PDF) (2 pp, 8K, February 2001, EPA420-F-01-006)
