The Urban Transportation Emissions Calculator has been developed as a simple, user-friendly tool for estimating annual greenhouse gas (GHG) and criteria air contaminant (CAC) emissions from passenger, commercial, and urban transit vehicles. The primary input to the Tool is vehicle kilometres travelled (VKT) for road vehicles and passenger kilometres travelled (PKT) for rail vehicles. Other inputs relating to average travel speeds, expansion factors, and vehicle fuelling characteristics can be modified from default values.
