Medium- and heavy-duty truck emissions in the United States fell roughly one percent in 2022, to 413 million metric tons of carbon dioxide equivalent (MtCOâ‚‚e). Since 1990, emissions from these vehicles have risen by roughly 75 percent.
Medium and heavy-duty trucks are a major contributor to transportation-related emissions in the U.S. In 2022, they accounted for roughly 23 percent of the sector's total emissions, with only light-duty trucks having a larger share. In 2021, the U.S. Environmental Protection Agency announced the Clean Trucks Plan – a series of regulations that aims to slash GHG emissions and air pollution from heavy-duty trucks.
