Environment module (ENV)

In order to compute the emissions from transport, the Environment Module (ENV) uses input from the TRA and the VFT modules: the vehicle-kilometres travelled per mode and per distance band and traffic situation and the information from on the national composition of the vehicle fleets and hence on the emission factors. Besides emissions, fuel consumption and, based on this, fuel tax revenues from transport are estimated by the ENV. Traffic flows and accident rates for each mode form the input to calculate the number of accidents in the European countries.

Expenditures for fuel, revenues from fuel taxes and value-added-tax (VAT) on fuel consumption are transferred to the macroeconomics module and provide input to the economic sectors producing fuel products and to the government model.
