Medium and heavy-duty vehicles are an essential part of our economy, moving billions of tons of cargo each year.
But they are also responsible for a massively disproportionate amount of pollution from on-road vehicles. Although MHDVs make up just over 1 in 10 of the vehicles on our roads, they emit over half of the fine particulate matter and nitrogen oxides from on-road vehicles and are also responsible for a disproportionate and increasing amount of climate-warming pollution. This pollution also leads to significant health issues including premature deaths and respiratory illnesses—particularly among populations close to ports, railyards, warehouses, and freight corridors.
Electrifying our on-road freight system is the surest way to reduce truck pollution and improve air quality. The number of zero-emission trucks has grown significantly recently, and key policies are accelerating their adoption. These policies not only reduce pollution but can also lower up-front costs directly and indirectly, enabling fleets to benefit from the operational savings of electric trucks sooner.
