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.

Total Cost of Ownership (TCO) Calculator

The Total Cost of Ownership (TCO) Calculator is an interactive tool developed by the International Council on Clean Transportation (ICCT) to help fleets, policymakers, and other stakeholders in the United States compare the lifetime costs of zero-emission battery electric powertrains and diesel commercial vehicles. Users can adjust key inputs—including vehicle type, annual mileage, charging strategy, and available incentives—to generate a side-by-side comparison of ownership costs, including vehicle purchase, fuel, maintenance, charging infrastructure, and residual value.
