Results - NMVOC Emissions

In this form the user has to provide the statistical energy consumption in case he/she wants COPERT to perform an energy balance. Providing values is not enough, the user also has to select to "Apply statistical correction". Data provided here are for primary fuels only, and there is an option to provide 2 different Petrol, Diesel and LPG energy consumption values is such information exists. Different values denote that in the Fuel>Specifications form different fuel characteristics have been provided by the user.

In order to balance the statistical and the calculated energy consumption the software follows a two step approach. First it matches the fossil/bio energy consumption ratio defined in the statistical values by modifying the blend type and blend share Vehicles>Blend Share. Once this is achieved a second modification to the mileage is applied in the form of a correction factor in order to match the total statistical energy consumption level. These updated values for both the fuel blend characteristics and the annual mileage are then used to calculate the total emissions.
