The Biden administration on Monday proposed curbing pollution pouring out of the tailpipes of new tractor-trailers, buses and other heavy-duty vehicles that forms smog, along with emissions warming the planet.
10 steps you can take to lower your carbon footprint
The Environmental Protection Agency proposed a new rule to cut the emission of nitrogen oxides — poisonous and reactive gases that can cause asthma attacks — from engines in some of the biggest vehicles on roadways. In the same proposal, the agency will also consider further limiting the amount of carbon dioxide these vehicles spew into the air.
The proposed smog rule marks the first update to heavy-duty tailpipe standards in two decades and come as Biden is seeking ways to advance his environmental agenda outside Congress. They would apply to not only huge 18-wheelers hauling freight on highways, but also many school buses, delivery vans and moving trucks.

The pollution from diesel-powered trucks has a disproportionate impact on low-income communities and those of color located near highways, ports and other heavily trafficked sites. The surge in delivery orders to people’s homes during the pandemic has worsened air pollution in some neighborhoods near the scores of warehouses built in recent years to satisfy America’s growing online shopping habits.
“These overburdened communities are directly exposed to pollution that causes respiratory and cardiovascular problems, among other serious and costly health effects,” EPA Administrator Michael Regan said in a statement.
Here's how Biden's unwinding Trump's environmental legacy
In Manhattan, for instance, all but one city bus depot is housed in Harlem or other historically minority neighborhoods north of 96th Street. On the other side of the country, pollution from trucks carrying goods out of the ports of Los Angeles and Long Beach falls heavily on the health of the many Hispanic neighborhoods living alongside I-710 and other roads inland.
“All along that freeway, there are two dozen communities which see several hundred thousand trucks and cars each day,” said Ed Avol, a professor of clinical preventive medicine at the University of Southern California.
Elva Cordoba, 71, has to breathe the fumes from cargo trucks nearly every day from her duplex abutting a large parking lot in San Bernardino, east of Los Angeles. The parking lot next to a Pizza Hut along W. Base Line Street is a regular staging ground for semi-trucks, and Cordoba says six or seven of them are often parked there.
“When it’s hot outside, the environment gets very bad, the air is very dirty,” said Cordoba, a native of Guadalajara, Mexico. She has lived in her house for 22 years, just over a mile from city hall.
The fumes give her allergies, red and inflamed eyes, and cause her to snore, she said. One of her adult sons moved to Washington state because of health problems because of the poor air quality.
While some environmentalists welcomed the new proposals, other criticized the Biden administration for failing to take more aggressive steps to spur the sale of electric trucks that emit no air pollution.
“Any rule that doesn’t include requirements that some of these new trucks be electrified seems to be a missed opportunity,” said Paul Cort, an attorney with the law firm Earthjustice who used to work at EPA’s Office of General Counsel as a career lawyer.
Nitrogen oxides form when gasoline, diesel and other fossil fuels burn at high temperatures, and breathing them can trigger asthma attacks and lead to other health problems. When wafted into the air, these gases contribute to smog, soot and acid rain.
About 72 million people live within 200 meters or about 220 yards of a truck freight route, the EPA estimates. Avol said many of these communities with “higher exposures” to these pollutants “tend to be more at risk in terms of poorer health.”
The proposed requirements for nitrogen oxides would apply to heavy-duty vehicles made in Model Year 2027, and within another four years would cut average emissions by 90 percent below today’s federal standards. If adopted, they would put the entire country in line with standards for heavy-duty vehicles adopted by California.
The air pollution gains would avert up to 2,100 premature deaths and 18,000 cases of childhood asthma annually, according to the EPA. The agency, which aims to finalize the regulation by the end of the year, will also consider a less stringent option.
“It’s a really important rule,” said Paul Billings, a senior vice president at the American Lung Association. “It saves a lot of lives, and reduces a lot of pollution.”
EPA is also proposing to tighten greenhouse gas emissions from certain heavy-duty vehicles — including school buses, transit buses, commercial delivery trucks and short-haul tractors — made starting in 2027. The transportation sector is the nation’s largest contributor to climate change, and heavy-duty trucks make up nearly a quarter of all greenhouse gas emissions from vehicles.
