Around 6% of total EU GHG emissions, more than 25% of emissions from road transport and huge dependence on imported fossil fuels: The climate footprint of heavy-duty vehicles highlights the need for action. The proposal to tighten CO2 standards for new heavy-duty vehicles is not only the EU Commission's response to the almost steady increase in transport emissions since 2014; it is also intended to strengthen competitiveness of European manufactures and reduce energy dependency. However, successful decarbonisation needs a more comprehensive approach. What this must include is the subject of an AK EUROPA position paper.
