Follow-up model of heavy duty vehicles emissions by the EU

In the EU, lorries, buses and coaches emits some 5% of total GHG-emissions. Despite improvements in fuel efficiency these emissions increases and are currently 19% above 1990 levels. Forecasts indicate further increase of emissions in this industry if no curbing measures are implemented. In order to enable a better follow up on effect from actions to curb further increase of emissions, the Commission has developed the Vehicle Energy Consumption Calculation Tool (VECTO). VECTO is a software that cost-efficiently and reliably simulate the CO2 emissions and fuel consumption of HDVs for specific loads, fuels and mission profiles, based on relevant input data. NTM is following this model development and if it proves accurate this may be a model to be used in NTMCalc or could be used to calibrate present data.
