DETROIT – The Biden administration is proposing tougher pollution regulations for new tractor-trailers that will clean smoky diesel engines and encourage new technologies over the next two decades.
The proposal, released Monday by the Environmental Protection Agency, will require the industry to reduce nitrous oxide emissions from smog and soot by 2031 to 90% per truck compared to current standards. Emissions can cause breathing problems in humans.
Although truck manufacturers are working on power transmissions on battery electric and hydrogen fuel cells, the EPA says the proposal is not a requirement for zero-emission trucks. Rather, the agency says there are pollution control devices under development that can support diesel loading while cleaning the air.
The EPA is also tightening restrictions on greenhouse gas emissions that contain heat. Existing standards will be updated starting in 2027, and stronger new standards will begin in 2030. The requirements were last updated in 2001, and the next big step will be in 2024.
The new stronger standards will not apply to older trucks, which limits the impact of the new rules.
EPA officials say the new requirements are in line with President Joe Biden’s order to clean up transport, which is a major source of greenhouse gas emissions across the country. 29% of gases are emitted by transport, 23% – trucks. Biden is trying to halve greenhouse gas emissions by 2030 to combat the effects of climate change.
The new standards will bring widespread improvements in air quality, especially in areas already exposed to heavy truck traffic, officials say.
“Seventy-two million people live near freight routes in America, and they are likely to be colored people and those with lower incomes,” EPA Administrator Michael Regan said in a statement.
The agency says it offers several options to reduce pollution of heavy trucks and buses, and it will take into account public comments before developing final standards by the end of this year.
“The EPA has worked with stakeholders and identified several options in the proposal, including sustainability of standards, deadlines for phasing in standards, options to encourage early adoption of clean technologies and improving emission guarantees,” the agency said in a statement.
The EPA will also tighten requirements for school buses, transit buses, commercial delivery trucks and short-haul tractors, in areas where the transition to zero-emission vehicles continues.
Early versions of all-electric semi-finished products are now on sale, and the industry is testing trucks running on hydrogen fuel cells that generate electricity.
The EPA says new greenhouse gas standards could help speed up the transition to zero-emission trucks and buses that weigh more than £ 26,000.
Currently, cordless electric trucks have a limited range of motion, and it takes a long time to recharge your batteries. For trucks on hydrogen fuel cells, gas stations are scarce, and pollution occurs when most of the hydrogen is now produced from natural gas. But researchers are working on so-called “green hydrogen,” which will be produced using electricity from renewable sources such as wind or sun.
According to pollution standards, manufacturers will have to confirm that their trucks meet more stringent requirements or face fines. The EPA also wants them to extend emission control guarantees, making them more cost-effective for buying transport companies.
The new exhaust gas cleaning systems will cost more, as will the warranties that are likely to be passed on to truck and bus buyers. But the EPA says reducing pollution from the toughest option will save the country up to $ 250 billion from 2027 to 2045, largely by preventing deaths and reducing healthcare costs.
The EPA said stricter standards would prevent up to 2,100 premature deaths, reduce hospital admissions and emergency visits by 6,700 and prevent 18,000 cases of childhood asthma.
