The Urban Transportation Emissions Calculator (UTEC) is a user-friendly tool for estimating annual emissions of greenhouse gases (GHGs) and key air pollutants from personal, commercial, and public transit vehicles in an urban context.
UTEC is very easy to use and this Quick Guide will describe the basic steps on how to generate results quickly. The quality of the emission estimates will depend on the quality of the input data and ability to tailor default values to local conditions.
