This analysis estimates the number of charging points and hydrogen refueling stations needed to enable the transition to 100 percent sales of zero-emission Class 7 and Class 8 tractor-trailers by 2040 in the United States.

On-road diesel vehicles are the leading contributor to air pollution and associated disease burdens. Besides the impact on air quality and public health, black carbon from diesel engine exhaust produces significant near-term climate warming.

Air pollution poses a risk to human health at levels even below the emission limits established by the World Health Organization in Europe.

This briefing paper identifies several possible levels of stringency for the post-2021 CO2 standards in the European Union for light-duty and heavy-duty vehicles and compares them against economy-wide greenhouse gas reduction targets for 2030 and 2050, as well as the 2050 target for transport sector emission reductions in the EU Green Deal.
