Mr. Martinez presented the status quo on reducing CO2 emissions from heavy duty vehicles in the European Union. The work program was launched following a political commitment to reduce CO2 emissions by 80-95% below 1990 levels by 2050. According to an impact assessment, HDVs have a potential for a 40% improvement in energy efficiency by 2050. In Lot 1 of the work program, a HDV market survey in the EU was conducted. Lot 2 is intended to define the measurement procedure. The approaches explored so far are measurement on chassis dynamometer, measurement with PEMS and model simulation. The preferred option is component testing and model simulation with post-verification via measurement. With this approach, CO2 is calculated from a steady state engine fuel consumption map corrected by a transient correction factor derived from WHTC. So far, elaboration of the test procedure made good progress, but further development is needed. The HDV CO2 emissions strategy is tentatively planned to be adopted by the Commission by the first half of 2013. Mr. Martinez pointed out that the lead within the Commission for this dossier is with DG CLIMA. |
