The Environmental Protection Agency on Friday set strict emissions standards for heavy-duty trucks, buses, and other large vehicles, an action that officials said will help clean up some of the nation’s largest sources of planet-warming greenhouse gases.
The new rules, effective for model years 2027 through 2032, are projected to avoid up to 1 billion tons of greenhouse gas emissions over the next three decades and provide $13 billion in net benefits, according to the EPA. This move is expected to particularly benefit the estimated 72 million people living near freight routes, who suffer from disproportionate air pollution burdens.
“Heavy-duty vehicles are essential for moving goods and services throughout our country, keeping our economy moving. They’re also significant contributors to pollution from the transportation sector — emissions that are fueling climate change and creating poor air quality in too many American communities,” said EPA Administrator Michael Regan.
The regulations mark a significant step forward in the fight against climate change and air pollution, promising cleaner air, safer communities, lower fuel and maintenance costs for truck owners, and improved public health.
These standards follow closely on the heels of new automobile emissions standards for passenger vehicles announced by the EPA, aiming for similar strictness by model year 2032.
While the auto industry expressed concerns about meeting these standards, particularly regarding electric vehicle adoption, the EPA remains confident that the new rules will drive innovation and propel the industry toward sustainable growth.
Despite industry pushback, the EPA remains steadfast in its commitment to tackling climate change and advancing environmental justice. The new regulations are expected to provide greater certainty for the industry while supporting U.S. manufacturing jobs in advanced vehicle technologies.
Although challenges lie ahead, the EPA believes that offering a range of powertrain options will allow truck owners to make informed choices while still meeting stringent environmental goals.
The EPA calculated significant cost savings for operators over the next decade, emphasizing the immediate health benefits these regulations will bring to communities burdened by heavy truck traffic.
“Transportation is the largest source of pollution driving climate change,” remarked Harold Wimmer, CEO of the American Lung Association. “These strong standards that will help drive toward a zero-emission future for trucks, buses, and other heavy-duty vehicles are a critical part of the solution.”
