With the climatic change already classified by some governments and organizations as a climatic emergency, and with the aim of fulfilling the acquired compromises, such as the Paris agreement, European Union is developing several measures in order to reduce the CO2 emissions. One of the main contributors to CO2 emissions in Europe is the fleet of freight vehicles which are on the European roads daily, with a 25% of the total amount of CO2 emissions emitted by road transports. The EU has already tackled a big part of the problem, with the entry into force of regulations defining strict CO2 limits for passenger cars (WLTP cycle), as well as for trucks (VECTO). EU strategy is still ongoing, with different proposals for the extension of the scope of these measures, not only to include additional categories of vehicles, but also to evaluate the effect of innovative technologies on the fuel efficiency of those vehicles. One of those proposals is the extension of the scope of regulation (EU)2017/2400 implementing Regulation (EC) No 595/2009 of the European Parliament and of the Council as regards the determination of the CO 2 emissions and fuel consumption of heavy-duty vehicles and amending Directive 2007/46/EC of the European Parliament and of the Council and Commission Regulation (EU) No 582/2011 so as to include the effect of bodies for completed vehicles and trailers or semitrailers in the global efficiency of trucks. As a result of a public call for tenders from DG-CLIMA on the subject “Bodies and trailers – development of CO2 emissions determination procedure”, IDIADA, in association with Graz University of Technology and Transport & Mobility Leuven NV has defined a methodology to consider the effect of bodies and trailers on CO2 emissions. This paper will focus on the analysis of the different existing regulatory schemes worldwide that has been used as a starting point for the definition of the methodology. Furthermore, a comparison between such existing schemes and the proposed methodology is presented, considering the particularities of the European fleet of commercial vehicles. Finally, an overview of the next steps of the European union with regards to the introduction of such proposal as part of the European regulatory Framework will be analyzed.
