Heavy-duty vehicles (HDVs) are currently responsible for about one-fourth of fuel consumption and greenhouse gas emissions from the transport sector in the European Union. Within the HDV sector in the EU, tractor-trailers represent the largest share of CO2, accounting for roughly 70% of emissions.

On May 30, 2018, Canada published final standards to reduce greenhouse gas (GHG) emissions from new on-road heavy-duty vehicles. The new regulation is part of Canada’s economy-wide commitment to reduce GHG emissions 30% by 2030 compared to a 2005 baseline.

The China VI standard is among the world’s most stringent HDV emission standards and combines best practices from both European and U.S. regulations. It will be a key pathway to clean up diesel emissions and is therefore a critical step toward winning the war against air pollution in China.

On June 28, 2018, the Ministry of Ecology and Environment (MEE) of the People’s Republic of China released the final rule for the China VI emission standard for heavy-duty vehicles. The China VI standard will be implemented in two phases.

On May 17, 2018, the European Commission released a regulatory proposal for setting the first ever carbon dioxide (CO2) emission standards for new heavy-duty vehicles (HDVs) sold in the European Union.
