Truckers and Makers Seek Delays on U.S. and EU Emissions Rules

U.S. truck owners are urging the Environmental Protection Agency to go further than its proposed revisions to the 2027 heavy-duty NOx rules, with many seeking a full rollback and others criticizing the removal of extended emissions-equipment warranties. Other operators support cleaner trucks but want regulations to better account for equipment costs, reliability, small-business impacts and lifecycle emissions, including possible incentives to replace older vehicles. In Europe, seven major truck manufacturers are asking the European Union to delay its 2030 CO2-compliance timeline by three years, arguing that charging and hydrogen infrastructure, grid connections, energy prices and operating economics are not developing quickly enough. Zero-emission trucks account for only about 2.4% of new heavy-duty registrations in Europe, while manufacturers say meeting the targets would require a rapid expansion of truck chargers, policy incentives and infrastructure investment. The competing pressures highlight the challenge of reducing heavy-truck emissions while keeping new equipment commercially viable for carriers.
