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.
