Modeling and Calculator Tools for State and Local Transportation Resources
The links below provide access to several easy-to-use calculators and more sophisticated modeling tools to assess the effectiveness of mobile source-based control strategies. State and local agencies can use these calculators and tools to estimate emission reductions or to conduct an analyses of the outcome that a specific emission-reduction strategy may produce.
Modeling Tools and Inventories
Access MOVES (Motor Vehicle Emission Simulator) and other models and inventories. These models are methods used by EPA to estimate emissions from on-road vehicles, nonroad sources, and fuels. Inventories are calculations of total emissions of a pollutant for a given area at a defined time and set of conditions.
Run these calculators for estimates of emission reductions and fuel impacts associated with a particular transportation-related strategy:
- Airport Ground Support Equipment (GSE)
A spreadsheet tool that provides users with a quick analysis of the emission benefits and cost-effectiveness of controlling GSE emissions.
- SmartWay Truck Carrier Performance Tool
Conduct a thorough assessment of the environmental performance of fleet (truck) operations, and calculate additional fuel savings and emission reductions (carbon dioxide, CO2; nitrogen dioxide, NOx; and particulate matter, PM) that can be achieved through a range of options and strategies.
- Diesel Emissions Quantifier
Characterize a truck or bus fleet and calculate the tons of emission reductions (carbon monoxide, CO; CO2; NOx; hydrocarbons; and PM) that a retrofit project will generate.
