The recently published heavy-duty vehicle certification data from the European Union are a valuable source of information to assess the values of the CO2 standards baseline, track the progress of truck manufacturers towards their reduction targets, and understand the various technology pathways chosen by manufacturers to decarbonize their fleets. This paper analyses the baseline data to understand how the industry currently performs compared to the targets set out by the European Commission. The analysis is intended to inform the discussions on the review of the standards that will take place in 2022.
