Certification of CO2 emissions and fuel consumption of on-road heavy-duty vehicles in the European Union
On May 11, 2017, during the 67th meeting of the Technical Committee—Motor Vehicles, member states of the European Union unanimously adopted a draft implementing act put forward by the European Commission on the certification of the CO2 emissions and fuel consumption of heavy-duty vehicles. Starting January 1, 2019, heavy-duty vehicles belonging to one of the four vehicle groups with the highest contribution to on-road freight carbon emissions will be certified for their CO2 emissions and fuel consumption. Six additional heavy-duty vehicle groups will be required to be certified for CO2 emissions and fuel consumption by July 1, 2020. The certification procedure is based on a vehicle simulation tool that uses as inputs the measured performance of the different vehicle components.
