WASHINGTON — The Biden administration on Monday proposed strict new limits on air pollution from buses, supply vans, tractor-trailers and different heavy vehicles — the primary time in additional than 20 years that tailpipe requirements have been tightened for the most important polluters on the highway.

The brand new draft rule from the Environmental Safety Company would require heavy-duty vehicles to scale back emissions of nitrogen dioxide by 90 % by 2031. Nitrogen dioxide is linked to lung most cancers, coronary heart illness and untimely demise.

The E.P.A. additionally introduced plans to barely tighten emissions of carbon dioxide, a greenhouse gasoline that’s driving local weather change, from vehicles. The brand new guidelines would apply to vehicles starting with the mannequin 12 months 2027.

The truck air pollution rule is the most recent in a collection of recent air pollution insurance policies below President Biden, who’s looking for to scale back the emissions which can be dangerously warming the planet and rebuild environmental requirements that had been weakened by President Donald J. Trump.

Vice President Kamala Harris introduced the proposal, together with a collection of different federal clear transportation actions, together with the expenditure of $5.5 billion to assist states buy low or zero-emission transit buses, and $17 million to switch diesel faculty buses with electrical variations in underserved communities.

Late final 12 months, the E.P.A. tightened requirements on auto air pollution and introduced new guidelines governing methane, a climate-warming gasoline that leaks from oil and gasoline wells. This 12 months, the company is predicted to roll out new restrictions on greenhouse gases and on industrial soot launched by energy vegetation.

The administration is portraying the truck rule introduced Monday as central to Mr. Biden’s agenda of environmental justice, as many communities of colour are situated alongside highways and are topic to elevated ranges of air pollution.

“Seventy-two million persons are estimated to reside close to truck freight routes in America, and they’re extra prone to be folks of colour and people with decrease incomes,” the E.P.A. administrator, Michael S. Regan, stated. “These overburdened communities are straight uncovered to air pollution that causes respiratory and cardiovascular issues, amongst different severe and dear well being results. These new requirements will drastically lower harmful air pollution by harnessing latest developments in car applied sciences from throughout the trucking business because it advances towards a zero-emissions transportation future.”

Public well being specialists welcomed the transfer. “Cleansing up vehicles is a essential step to reaching the president’s imaginative and prescient not solely of environmental justice but in addition the most cancers moonshot,” stated Paul Billings, a senior vp on the American Lung Affiliation. “Diesel gasoline is a identified carcinogen.”

The brand new limits would forestall as much as 2,100 untimely deaths, 6,700 hospital admissions and emergency division visits, 18,000 circumstances of bronchial asthma in kids, 78,000 misplaced days of labor and 1.1 million misplaced days of college by the 12 months 2045, based on E.P. A. estimates.

The company estimates that the financial advantages of the rule might be as much as $250 billion and stated these advantages “would exceed its prices by billions of {dollars}.”

However truckers and producers say the rule is just too stringent and dear, and that compliance may ship greater costs rippling via the economic system.

“This new commonplace merely might not be technologically possible,” stated Jed Mandel, president of the Truck and Engine Producers Affiliation, an business group. “We’re apprehensive about the associated fee. There’s a potential of adversarial impacts on the economic system and jobs. No one desires to see union jobs laid off. Common lunch-pail, blue collar employees.”

Jay Grimes, director of federal affairs for the Proprietor-Operator Unbiased Drivers Affiliation, stated new restrictions could be particularly onerous for small truckers, which he stated comprise 90 % of the business.

“We’ve seen for the reason that begin of the pandemic the efforts truckers are making each day to maintain the provision chain secure,” Mr. Grimes stated. “Larger costs on the small enterprise aspect are going to get handed right down to customers within the provide chain.”

The federal authorities final up to date its truck emissions rule in 2001, when the E.P.A. required business vehicles to chop emissions of nitrogen dioxide by 95 % over 10 years. That contributed to a 40 % drop in nationwide nitrogen dioxide emissions, the company stated. It estimates that the brand new rule will contribute to a 60 % drop in emissions by 2045.

The E.P.A. known as the brand new rule the primary in a three-step “Clear Vehicles Plan” — a collection of fresh air and local weather change laws over the following three years designed to scale back air pollution from vehicles and buses and to speed up the transition to a way forward for all-electric, zero-pollution automobiles.

After a primary 12 months by which President Biden tried to push bold local weather laws via Congress, solely to see it stall, the administration is utilizing its regulatory equipment to attempt to curb air pollution.

The E.P.A. is engaged on new limits for auto air pollution, due out subsequent 12 months, which it hopes will speed up a transition to electrical automobiles. ​​Mr. Biden has pledged that half of all new vehicles offered in america by 2030 might be electrical automobiles.

Whereas the brand new truck laws will lower air pollution that harms human well being, they gained’t do a lot to scale back emissions that heat the planet, local weather specialists stated.

The proposed laws would require some vehicles, 17 of the 33 classes of industrial quality vehicles, to decrease their carbon dioxide emissions. That’s designed to bolster gross sales of all-electric vehicles in america, from fewer than 1,000 in 2020 to about 1.5 % of complete truck gross sales, or roughly 10,000 vehicles, in 2027.

However with a purpose to put america on a path towards a transition to all-electric vehicles, the forthcoming truck guidelines must be much more stringent, specialists stated.

“It’s nice to see that the rule is driving 90 % discount in air air pollution in heavy-duty automobiles and on the identical time opening the door to lowering greenhouse gasoline air pollution,” stated Drew Kodjak, govt director of the Worldwide Council on Clear Transportation, a analysis group. “However we’ve acquired this factor known as local weather change and we’ve actually acquired to begin driving electrification within the heavy-duty truck sector. My massive concern is that the proposal as it’s written won’t try this.”

Transportation is the biggest single supply of greenhouse gases generated by america, representing 29 % of the nation’s complete emissions.

The E.P.A. has stated it intends to create one other set of greenhouse gasoline guidelines for vehicles, starting as quickly as mannequin 12 months 2030, that might be “considerably stronger” than the present requirements, and designed to hurry the transition to all-electric vehicles.

“Ready for an additional few years to do the following set of greenhouse gasoline requirements for vehicles is fallacious. We simply don’t have time,” stated Margo Oge, an knowledgeable on electrical automobiles who headed the E.P.A.’s Workplace of Transportation and Air High quality from 1994 to 2012. “My hope is that they may use this time to strengthen the usual now.”

The rule introduced Monday might be open for public remark for 46 days, and the E.P.A. is predicted to finalize it by the tip of 2022.
