Heavy vehicles

Most buses and heavy-duty trucks rely on diesel engines that emit dangerous levels of particulates, nitrogen oxides, and other pollutants that cause chronic disease and premature death. Rising demand for freight transport means heavy vehicles contribute an increasing share of carbon emissions. Decarbonizing transportation will require cleaner engines and fuels, technological advances, and electrifying 29% to 81% of the global heavy-duty fleet by 2050. ICCT research identifies and promotes cost-effective technology and policy options for a cleaner freight sector.
