Many states and Washington, DC, together representing roughly 35% of the U.S. medium- and heavy-duty vehicle market, signed a Memorandum of Understanding with a shared goal of 30% zero-emission heavy-duty vehicle sales by 2030 and 100% no later than 2050. This group also shares a heavy burden from heavy-duty diesel NOx emissions. A major step these states and DC could take is to adopt a series of key regulations for medium- and heavy-duty vehicles. These include California’s Advanced Clean Trucks (ACT) rule, which requires the sale of at least 30% zero-emission trucks by 2030, and the Heavy-Duty Vehicle Omnibus rule, which requires a 90% reduction in NOx emissions from model year 2027 engines.

This webinar will present an overview of the annual and cumulative emission benefits available in Washington, DC, and sixteen states with the adoption of these key policies targeting medium- and heavy-duty vehicles.
