The brand new truck mandate is “actually a essential piece of the state’s local weather and clear air targets,” mentioned Patricio Portillo, a clear transportation advocate on the Pure Sources Protection Council. “A typical sight on California’s highways are vehicles clogging lanes, blowing thick smoke into the sky whereas overheated vehicles relaxation on the aspect. It’s so regular that we cease fascinated about it, however that exhaust permeating the air harms our lungs and our bodies.”
The air board will maintain a public listening to on the proposal on Oct. 27, after a 45-day public remark interval. It comes just some weeks after the air board handed one other far-reaching mandate that bans gross sales of gas-powered automobiles by 2035.
California has been ratcheting down emissions from diesel-powered vehicles and buses for many years in an effort to fight the state’s extreme air air pollution. The brand new proposal builds on a clear vehicles regulation handed in 2020, which steadily will increase the variety of zero-emissions vehicles that producers should promote, beginning in 2024.
The provisions requiring turnover of current fleets would apply solely to federal businesses and so-called “high-priority fleets,” that are owned or operated by firms with 50 or extra vehicles or with $50 million or extra in annual income. Included are vehicles weighing 10,001 kilos or extra and bundle supply autos of 8,500 lbs or extra, together with U.S. Postal Service, FedEx, UPS and Amazon fleets.
These giant firms and federal businesses would have a alternative on the right way to comply: They might buy solely zero-emissions autos starting in 2024 whereas retiring diesel vehicles on the finish of their helpful life. Or they might phase-in zero-emissions vehicles as a proportion of their complete fleet, beginning with 10% of supply vehicles and different varieties which are the simplest to impress in 2025, then ramping as much as 100% between 2035 and 2042.
The necessities for changing fleets wouldn’t apply to smaller firms, except they have been utilizing a bigger firm’s vehicles. They might hold their vehicles so long as they need beneath the proposal, though their new purchases must be zero-emissions by 2040, in keeping with Tony Brasil, chief of the air board’s transportation and expertise department.
“We additionally imagine that a number of the market dynamics will in all probability encourage fleets to exchange their vehicles earlier,” Brasil mentioned. “As new zero-emissions vehicles turn out to be out there, the price of operation is significantly decrease.”
Working towards the 2040 ban on new diesel and gasoline vehicles, the proposal has different deadlines for phasing in new gross sales, various based mostly on the kind of truck.
Drayage vehicles — used largely to move cargo from ports and railways — would have the strictest timeline. New fashions can be zero-emissions in 2024, whereas diesel and gasoline drayage vehicles should retire after 18 years to ensure that they meet a zero-emissions requirement by 2035.
As well as, half of all new vehicles bought by state and native governments can be zero-emissions in 2024, rising to 100% by 2027. Some exemptions are allowed, if there’s a lack of obtainable fashions. Counties with small populations, together with Inyo, Butte, Mendocino and Tuolumne, can be exempt till 2027.
The brand new rule banning sale of diesel autos wouldn’t apply to emergency autos, equivalent to ambulances.
Some producers have already introduced plans to ramp up gross sales of electrical truck fleets. Tesla plans to roll out electrical semi vehicles with 500 miles of vary later this year, whereas Volvo Vehicles and Nikola Inc. have launched electrical large rigs and different fashions with ranges of as much as 350 miles. Volvo Vehicles this 12 months set a world purpose that half of its truck gross sales can be electrical by 2030.
“We’re decided to steer the transformation of the transport trade,” Roger Alm, president of Volvo Vehicles, mentioned in an announcement. “The curiosity amongst clients is excessive and it’s rapidly changing into a aggressive benefit for transporters to have the ability to supply electrical, sustainable transports.”

However challenges with the transition stay.
Many electrical heavy-duty vehicles at the moment in the marketplace nonetheless lack the vary wanted to move cargo statewide and throughout state traces. Some autos like drayage vehicles are higher fitted to electrification as a result of these autos might not want as lengthy of a automobile vary, mentioned Shimoda of the California Trucking Affiliation. However for long-haulers, the mandate might pose critical issues, he mentioned.
Lengthy-haul diesel vehicles can function as much as 1,000 miles earlier than needing to refill the tank, which takes 10 to fifteen minutes to refill. However electrical fashions must be charged actually because they’ve “considerably shorter vary” they usually take hours to cost.
“The charging infrastructure that’s essential to assist these vehicles is principally non-existent at the moment. Even the quickest out there chargers proper now are going to take 3 to 4 hours to cost as much as a full state,” mentioned Shimoda, who represents California truckers.
Todd Spencer, president and CEO of the Proprietor-Operator Impartial Drivers Affiliation, mentioned charging instances of greater than two hours might “trigger complete disruption” of the trade.
“Neither the expertise nor the interstate infrastructure can be out there within the foreseeable future to assist a zero-emissions requirement for long-haul interstate vehicles,” he mentioned.
Some new expertise, nevertheless, has already surfaced that dramatically cuts the charging time. The most recent mannequin of the Volvo eVNR tractor-trailer can recharge to 80% in simply 90 minutes.
The mandate additionally would enhance demand on the state’s already-fragile electrical grid.
“These charging stations are going to be an enormous, large energy draw,” Shimoda mentioned. “To place into context, the Levi’s Stadium in Santa Clara on a sport day makes use of round 300 to 350 kilowatts of energy. A charging station wanted for a giant rig goes to be like 30 instances bigger.”
Stanley Younger, an Air Sources Board spokesperson, mentioned many issues over the charging infrastructure are already being addressed beneath the buildout of the grid outlined within the state’s proposed scoping plan, its local weather change blueprint.
Although new mannequin costs are excessive, electrical vehicles would want a lot decrease upkeep prices over time in comparison with fossil-fueled engines and recharging with electrical energy would save more cash than utilizing diesel.
Shane Levy of Proterra, an electric-vehicle expertise firm, mentioned the corporate has quickly scaled up its battery expertise in recent times. It’s at the moment working with greater than a dozen producers to impress medium- and heavy-duty vehicles and has delivered battery techniques for greater than a thousand industrial autos.
He mentioned the brand new rule might speed up the market.
“Industrial autos are ripe for electrification — benefiting not solely how we transfer folks round cities and cities, but additionally how we offer items and companies to the communities we dwell in,” he added.
Some state and federal subsidy packages might additionally assist present reduction to firms and truck drivers.
Though the board supplied no price information, employees mentioned the long-term financial internet advantages are anticipated to avoid wasting firms about $22 billion over the lifetime of the regulation and can save greater than 5,000 California lives between 2024 and 2050, in keeping with air board employees’s estimates.
Environmental teams say the deadlines needs to be accelerated by 4 years — from 2040 to 2036 — for all gross sales of latest zero-emissions vehicles.
Portillo, of the Pure Sources Protection Council, mentioned dashing up the transition would have well being advantages for low-income, deprived communities that dwell close to highways, railyards and ports, the place vehicles spew poisonous diesel exhaust and smog-forming pollution.
Diesel exhaust is without doubt one of the most dangerous pollution that threaten Californians’ well being, containing greater than 40 carcinogens in addition to particles that contribute to cardiovascular and respiratory illness.
