The European Parliament is set to amend the way of calculating emission credits for heavy-duty vehicles for the 2025–2029 reporting period.

The move will accelerate changes to the. For lawmakers, the adjustment is necessary to provide certainty for vehicle manufacturers, while opponents argue that the move could undermine the EU’s climate targets.

The change relates to the regulation governing CO₂ emission standards for heavy-duty vehicles, which the EU established as part of its efforts to decarbonise the road transport sector.

Under the current framework, manufacturers must meet progressively stricter emission reduction targets, with compliance assessed through a system of emission credits linked to vehicle performance.

Heavy-duty vehicles, including trucks, buses and coaches account for a significant share of emissions from road transport in Europe. While they represent a relatively small proportion of vehicles on the road, they produce a disproportionate amount of transport-related greenhouse gas emissions.
