State plan calls for more electric trucks

Colorado’s trucking industry will need to start investing in zero-emission semitrailers, buses and delivery trucks as soon as 2027 as part of the state’s strategy to reduce greenhouse gas emissions, the cause of climate change.

e Colorado Air Quality Control Commission has approved a plan to convert most of the medium- and heavy-duty trucks sold in the state to electric vehicles or vehicles that run o of hydrogen fuel cells, starting in 2027, with a goal to have 40% of all semitrailers sold running on zeroemission engines by 2035.

e plan, which is modeled after a rule created in 2020 in California, does not require companies to buy these trucks, but instead orders truck manufacturers to sell the vehicles.

“ e manufacturers are required to make sure they meet a certain percentage of sales targets so it will encourage them to bring their vehicles to Colorado and provide attractive pricing for those vehicles,” said Will Toor, executive director of the Colorado Energy O ce.

e new rule also requires companies that operate diesel- or naturalgas-powered trucks to move toward lowered nitrogen oxide emissions.

ose emissions are a precursor to ozone pollution.

e plan was unanimously approved after nearly three days of hearings last week and it had support from elected o cials as well as environmental organizations and community groups, who said the new rule would improve air quality, especially for communities that are adjacent to the three major interstates that run through Colorado.

e new rule received some opposition from those who expressed concern that the utility grid will not be powerful enough to support thousands of semitrailers that need to be charged daily. Others expressed concern that technology won’t be developed fast enough to support the requirement, while some worried about independent truck drivers’ ability to invest in electric vehicles.

And Weld County o cials opposed the rule because they wanted vehicles powered by natural gas included in the plan.

E ort to reduce Front Range air pollution

But Colorado regulators are in a hurry to reduce air pollution in the state after the Environmental Protection Agency in September reclassied the state’s air quality as being in “severe non-attainment” of federal ozone standards. at designation comes with expensive penalties for private industry and consumers, such as more stringent permitting and higher gas prices during the summer.

Medium and heavy-duty trucks emit nitrogen oxides and particular matter, compounds that contribute to ozone pollution on hot days, and cars and trucks are the second-largest sources of greenhouse gas emissions in the state, Garry Kaufman, director of the Colorado Department of Public Health and Environment’s regulatory a airs program, said during a presentation on the new rule.

On high ozone days, the thick smog blankets much of the Front Range, causing respiratory problems for people working or exercising outdoors and reducing visibility of

Colorado’s majestic mountains.

While the Front Range is mandated by the EPA to reduce its ozone pollution, people living in mountain communities also supported the move, saying a haze often lingers there, too.

“It’s not just about heavy powder days or big raft days,” Glenwood Springs Mayor Jonathan Godes testied during a public hearing. “It’s about the health of our entire city.” e new plan requires auto manufacturers to produce a specied number of zero-emission medium- and heavy-duty trucks to sell in Colorado, starting with 2027 models. Trucks that run on electric batteries and fuel cells will count as zero-emission vehicles, and companies will get partial credit for hybrid vehicles. e percentage of zero-emission trucks that need to be on the roads increases each year through 2035, and the goals vary for pickup trucks and vans, delivery trucks and semitrailers.

Federal and state tax credits are available to help companies o set the cost of buying zero-emission vehicles.

When questioned about whether or not there would be enough inventory to meet the demand for zero-emission trucks, Kaufman told the Air Quality Control Commission that manufacturers are heading in that direction and he believed there would be.

“It’s not science ction technology,” Kaufman said. “It’s happening now.”

Trucking industry raises concerns about power grid e Colorado Motor Carriers Association, a trade organization for the trucking industry, said it supports a transition to zero-emission vehicles, but did not back Colorado’s plan.

Representatives from the association were not available for an interview at deadline, but the group presented a rebuttal to the state plan during last week’s hearing. e organization argued that Colorado has not invested enough money into the transition and that the state’s infrastructure will not be able to support electric semitrailers.

It could take up to 1 megawatt — enough to power 350 homes — to fully charge a semitrailer, and it could take eight hours of charging to power up a truck to drive 350 miles, the motor carriers’ rebuttal said.

“As more electric trucks hit the road, the projected power needs for a big truck stop by 2035 will equal that of a small town,” the group said in its document, which cited a study by the utility company National Grid Plc. “In that study, they further identi ed that a connection to the grid that can handle more than 5 megawatts may take up to eight years to build, at a cost of tens of millions of dollars. Without some tremendous power upgrades to the grid, the transition to electric trucks will be constrained by a grid unprepared for the demand.”

But Toor said the threats of power grid failure are exaggerated. e state legislature years ago ordered utility companies to begin preparing for a switch to electric vehicles and there’s enough capacity to handle it, he said.

Plus, the urgency for reducing greenhouse gas emissions and ozone pollution is strong for the air quality commission. And the amount of support for the move far outweighed opposition during the hearing.

Electrifying trucks and vans will bene t public health, said Jacob Smith, executive director of Colorado Communities for Climate Action. As the transition to zero-emission trucks occurs, air pollution levels are expected to drop in areas where people live along highways and near warehouses and trucking distribution centers.

“It’s a big deal from an equity perspective,” Smith said. “A lot of vulnerable communities also happen to be in close proximity to highways, manufacturing and distribution centers.”
