The CO2 standards required for trucks and buses for Europe to meet its climate targets

The European Commission will review the currently adopted CO2 emission standards for heavy duty vehicles (HDVs) by the end of 2022. The current standards require most new trucks to reduce their emissions by 15% in 2025, and 30% in 2030. However, growing levels of activity in the HDV sector offset the CO2 benefits from the standards, with emissions projected to grow by 8% by 2050 under the current adopted policies. This study seeks to inform the stringency of CO2 emission standards necessary to align the HDV sector with the European Climate Law. Specifically, this analysis depicts the contribution of emissions reduction that the HDV sector must make to equitably contribute towards Europe’s goal of climate neutrality by 2050—through achieving a 98% emissions reduction by 2050 relative to 2019.
