Calculator

This calculator lets users calculate pollutant emissions, specifically for transit bus, shuttle bus, and rail systems.

This calculator builds upon the earlier Fuel and Emissions Calculator. Updates include addition of light-duty vehicles, biodiesel, and more recent electricity emissions data. 

In 2015, NCST researchers began work on GreenFLY.ucdavis.edu, a demo flight search website that shows the emissions of each flight as

This tool is for fleet managers who want to better predict the benefits of low-rolling resistance (LRR)tires for both constant and transient speed operations.
