EPA considers tougher emissions rules for heavy-duty trucks

WASHINGTON – U.S. Environmental Protection Agency (EPA) will consider adopting more stringent greenhouse gases emissions rules for heavy truck The agency told Reuters after Congress passed new incentives to accelerate the adoption of zero-emission vehicles.

In March, the EPA proposed new rules to cut smoke and greenhouse gas (GHG) emissions from heavy-duty vehicles. The agency said it would reopen the proposed GHG rules after the Climate and Spending Inflation Reduction Act was passed in August, a move that could accelerate the US transition. to heavy duty electric vehicles.

EPA will issue an additional notice on the development of the proposed rule to consider more stringent GHG standards for model years 2027 through 2029 in December.

“The big change here is the Inflation Reduction Act. Congress has certainly sent a very strong message backed by worthy resources,” EPA’s Office of Air and Radiation Office official Joseph Goffman told Reuters. tell.”

EPA believes there could be a much higher zero-emission vehicle adoption rate between 2027 and 2029.

The EPA still plans to finalize the proposed rules for smoke trucks by December.

Jed Mandel, president of the Truck & Engine Manufacturers Association, which represents companies such as Daimler Trucks, Caterpillar and Cummins, said Wednesday that “putting on all these rules and regulations Being active in a concert is extremely important and very challenging.”

Mandel said it remains unclear how incentives under IRAs “will impact the industry going forward.”

The nonprofit RMI said the $40,000 Qualifying Commercial Clean Vehicle tax credit “will promote the adoption of electric-powered heavy- and mid-size trucks.” and will do electric truck works cheaper diesel in most cases.

In March, the EPA said the new heavy-duty truck GHG standards, when fully implemented, would result in 24% to 25% lower carbon dioxide emissions, but environmentalists have pressed the agency. have to do more.

“It is important that EPA policies are aligned with the urgency of the climate and air quality crises,” said Katherine Garcia, transportation officer for the Sierra Club. … The authorities are quick to finalize the heavyweight standards in the near future.”

The EPA in March proposed stricter standards for 17 of 33 tractor and vocational vehicle subcategories, including school buses, transport buses, commercial vehicles delivery truckand short haul tractors.

Next month, the California Air Resources Board (CARB) will review new regulations to require the rollout of zero-emission trucks starting in 2024″ and will establish a clear end date for vehicle sales. new medium and heavy-duty internal combustion engines by 2040.”

CARB President Liane Randolph told Reuters the board would vote on purchase requirements for a fleet of 50 or more delivery vans to transition to zero-emission purchases. “They need to convert to zero,” says Randolph.

Transportation is the largest source of U.S. GHG emissions, accounting for 29 percent of emissions, and heavy-duty vehicles are the second-largest contributor, with 23 percent, the EPA said.
