EPA's Green Vehicle Guide gives information about the environmental performance of vehicles and provides the user with dynamic search and sort capabilities. Side-by-side comparisons can be performed for up to three vehicles and searches can be customized based on user choices by using the Advanced Search function. Photos of models are displayed (if available) for basic searches and side-by-side comparisons.
To compare environmental performance across vehicle classes, use the 0-10 scores and the fuel economy numbers. These can be used to compare any vehicle to any other vehicle, no matter what types of vehicles you are comparing. Larger numbers, whether scores or fuel economy, are more environmentally friendly than smaller numbers.
And for the easiest comparison of all, use the SmartWay and SmartWay Elite designations. These indicate the vehicles with the best environmental performance compared to all other vehicles, where EPA certifies that these vehicles have exceeded environmental thresholds on the Air Pollution and Greenhouse Gas Scores.
