Diesel trucks, oil tankers and other ships must comply with two new rules that are the state’s most ambitious strike against smog in a decade. The cost could reach nearly $7 billion.
Ships and trucks will be required to cut thousands of tons of air pollution in communities near ports, freeways and warehouses under a pair of rules unanimously adopted by the Air Resources Board today.
The rules overhaul regulations for diesel truck exhaust and expand emission reductions from ships idling in California’s ports. The two rules, when fully implemented, are expected to eliminate some 10,000 tons of pollution per year, the state’s biggest strike against smog in twelve years.
Some of the nation’s most powerful businesses — oil companies, engine manufacturers and ports — opposed the new rules, saying the battered economy cannot weather changes that could reach nearly $7 billion. The air board’s hearings on the two rules lasted more than eight hours, with dozens of people voicing support and opposition.
Moving goods from ship to truck to warehouse accounts for nearly a third of California’s economy, but about half of its air pollution. Much of the pollution affects disadvantaged communities and communities of color near ports, freeways and freight corridors.
Diesel trucks are California’s number one source of a key ingredient of smog called nitrogen oxides, and they produce about a quarter of cancer-causing soot emitted statewide. Although federal efforts to clean up trucks have stalled, California will nevertheless need to slash nitrogen oxides and soot in order to meet federal health standards.

Projects that tackle vehicles, pollution in low-income communities, prescribed burns and even cows have lost 14% of their original budgets because of cap and trade shortfall.
In June, California adopted the world’s first regulation requiring manufacturers to ramp up sales of zero-emission trucks and buses over the next 15 years. But conventional heavy duty trucks will remain on California’s roads, spewing fumes in communities near railyards, ports and warehouses.
Traffic and slow speeds prime trucks to pump out nitrogen oxides — but right now, certification tests fail to capture those conditions. The new regulations require manufacturers of medium and heavy-duty engines to test them in ways that more closely mimic real traffic, and to extend the lifetime of emissions-control technologies.
Engines also must meet tighter standards that cut nitrogen oxides by 75 percent starting in 2024, and 90 percent starting in 2027. Particulate pollution standards will be cut in half starting with 2024 models.
The costs of these changes total about $4.5 billion between 2022 and 2050. A model year 2031 engine would cost roughly $6,000 more over its lifetime, about a 6 percent increase.
Manufacturers objected to the cost and the timeline.
“The rule is not technically sound or cost-effective, and…fails to provide the legally mandated minimum lead time,” said Jed Mandel, president of the Truck and Engine Manufacturers Association. “If implemented the rule will not achieve its air quality goals, and will harm California’s economy.”
But air board officials said the health benefits are also significant — avoiding 3,900 premature deaths and 3,150 hospitalizations across the state, which translates to health benefits of about $36.8 billion.
Ivette Torres of the Center for Community Action and Environmental Justice, based in the Inland Empire, called the rule a step in the right direction in resolving the “tremendous health impacts heavy trucks have had on our communities,” which has suffered unhealthful smog levels for most of August.
Home to the busiest ports
Another rule approved today expands pollution controls on ships that dock in California’s ports thousands of times a year. California is home to some of the busiest ports in the country. Even sitting still in harbors, ships churn out tons of pollutants that drift to neighboring communities, particularly near major ports in Long Beach, Los Angeles and Oakland.
The new requirements bolster clean-air mandates that ports already have implemented over the past decade.
Since 2014, all ships have been required to switch to cleaner-burning fuel within 24 nautical miles of the coastline. And container, cruise and refrigerated cargo ships at California’s six largest ports must reduce their emissions by cutting auxiliary engines and plugging into the electric grid, or capturing the pollution billowing from their smokestacks.
The new standards — to be phased in from 2023 through 2027 — toughen those mandates, and broaden the requirements to include auto carriers and oil and fuel tankers, as well as additional ports and terminals.
That means ships making roughly 6,300 visits to California’s ports every year must comply, up from 4,000 under previous rules. By 2031, the new rule will eliminate roughly 2,000 tons of smog-forming gases and diesel soot per year.
Longshoremen worry that the increased costs of the regulations might push shipping companies to less-regulated ports across the country.
“We depend on the jobs that the port provides for us,” said Danny Miranda, president of International Longshore and Warehouse Union Local 94. “Without a national standard on air quality, we lose competitiveness with the other ports, and it has a great effect on our economy.”
The ship regulation will cost about $2.23 billion, including installation of shore power and systems that scrub pollution from smokestacks. That will add about $4.65 per cruise ticket, $7.66 for each car coming off an auto carrier and less than 1 cent per gallon of fuel in a tanker, according to the air board’s estimates.
Miranda said he was especially concerned given the economic crisis and recent drops in trade during the coronavirus pandemic. Ports are rebounding, however: the Port of Long Beach reported that July was its busiest month ever.
At the board hearing, oil company officials who opposed the rules said that the estimates for how much tankers pollute is overstated. But electrical workers welcomed the new jobs that increased demand for shore power would create.
Bad air around ports
Environmental advocates and residents say the regulations will help clear the air for several million people who live in communities near ports, where pollutants trigger asthma attacks and other health problems. But some said that the regulations don’t move fast enough.
“Keep in mind, these emissions reductions still won’t kick in for another couple years,” said Francis Yang, the Long Beach and South Los Angeles community organizer with the Sierra Club’s My Generation campaign. “That’s more time that ships get to continue to pollute our air. That’s more time for the same frontline communities to have to wait to breathe.”
Within three years, ships and harbor craft are expected to be one of the leading sources of nitrogen oxides in the Los Angeles basin, which is home to some of the dirtiest air in the country.
Ship engines also spew diesel exhaust, which is a well-documented carcinogen linked to lung cancer, and fine particles that increase the risk of heart attacks and asthma attacks.
The air board estimates that the new regulations will cut the cancer risk from ship pollution by more than half, and will save $2.32 billion in avoided deaths, hospitalizations and emergency room visits, particularly in disadvantaged communities.
“Our communities do experience high incidences of cancer and other respiratory illnesses and cardiovascular disease,” said Taylor Thomas, a research and policy analyst for East Yard Communities for Environmental Justice, which represents residents of Southeast Los Angeles and Long Beach. “Being able to clean up these industries and especially at the ports will really go a long way in reducing the negative health impacts that our communities experience.”
California’s previous rules cut auxiliary engine emissions from container, refrigerated cargo and cruise ships by about 80 percent, averaged across fleets idling at six major ports including Los Angeles, Long Beach and Oakland.
But this excludes the roll-on/roll-off ships that carry cars and other rolling cargo, as well as tankers that account for about half of the pollution produced by docked ships. That means the communities around ports where these ships primarily dock, such as the Richmond and Stockton areas, don’t see the same protection.
Under the new rules, auto-carriers and tankers must cut portside pollution by roughly 90 percent beginning in 2025, according to air board staff. The targets for tankers start in Southern California, and expand north in 2027. Any terminal that exceeds a 20-visit threshold must comply. Ship and terminal operators can also comply by cutting pollution surrounding the port rather than at-berth, provided the air board approves.
Officials with the South Coast Air Quality Management District, which is responsible for cleaning the air in Los Angeles, Orange, San Bernardino and Riverside counties, advocated for a shorter deadline for some provisions. They worry that the emissions cuts won’t come soon enough to meet federal health standards for ozone, a key component of smog, by 2023.
“We’re facing some hard deadlines,” said Sarah Rees, assistant deputy executive officer in planning for the air district. “Two years is too long.”
Matt Arms, the Port of Long Beach’s director of environmental planning, said that the infrastructure improvements the regulation calls for will take time. For instance, devices that scrub pollution from ship smokestacks, called bonnets, are not one size fits all. The existing ones work for container ships, but bonnets for oil tankers are still under development.
“It’s not like you can go and run another extension cord,” Arms said. “They’re not challenges that can’t be overcome. I’m a little bit concerned about just how quickly they can be overcome.”
