Clean Vehicles Europe versus Ecoscore - Analysis and comparison of website and methodology

Research output: Book/ReportCommissioned report


On 3 December 2010, the Clean Vehicle Portal (CVP), sponsored by the European Commission and run by TÜV NORD, was launched. This portal was set up as an operational instrument under the European Commission Directive 2009/33/EC on the promotion of clean and energy-efficient road transport vehicles, which came into force before the launch of the portal. The website is meant as an easy-to-use tool for those in charge of vehicle procurement for government agencies, NGOs and businesses, as well as individuals, to compare the environmentally relevant 'operational lifetime cost' (OLC) of different vehicles. This should allow users to choose "the cleanest and most energy-efficient vehicles available". The Directive 2009/33/EC requires that from 4 December 2010, each purchase of vehicles for public transport services should take into account their energy consumption, CO2 emissions and pollutant emissions. The new portal therefore provides information on legislation for clean and energy-efficient vehicles at EU level and in all member states; it provides access to technical data and it facilitates joint procurement.
The Ecoscore website ( is sponsored by the three Belgian regions (Flanders, Wallonia and Brussels) and maintained by VITO in collaboration with the Vrije Universiteit Brussel. The website is meant to inform end users on the environmental performance of all passenger cars available on the Belgian market (new and second hand). The database behind this tool is composed of data from FEBIAC (Belgian Automobile and Two-wheeler Federation) and DIV (Belgian federal service for vehicle registrations).
In this report, the Clean Vehicle Europe (CVE) and Ecoscore methodologies are compared, as well as the specifications and user-friendliness of the CVP and Ecoscore website. Both methodologies are then used to calculate the environmental impact of a selection of cars and compare the ranking of vehicles with both methods. Hence, the value of the Ecoscore website is evaluated in the framework of the new European CVP.
