Vehicle and fuel comparisons

This data tool allows users to see modeled emissions from representative old (1998 and 2005) diesel vehicles and compare those to emissions of modern (2018) vehicles of a variety of fuel types.

The tool provides emissions data for a variety of pollutants. This tool allows users to explore the emissions benefits of upgrading different vehicle types to modern technology. It includes a representative sample of heavy-duty diesel vehicles. The model used to develop this tool is limited to on-road vehicles and only includes a certain set of alternative fuel technologies. Therefore, the tool does not include off-road equipment or all eligible on-road vehicles, and there may be some modern alternative fuel technologies available that are not represented here.
