Tesla’s Semi is arriving at scale just as Europe’s largest truck manufacturers are in federal court fighting the climate policies designed to prepare them for exactly this moment. The auto industry has made this mistake before.
Daimler Truck, Volvo Group, and Traton — the parent company of International Motors — filed a motion through the Truck and Engine Manufacturers Association to defend the Trump EPA’s repeal of the 2009 endangerment Finding and the repeal of all motor vehicle climate standards.
When Elon Musk first pushed electric cars into the mainstream, much of the auto industry dismissed them as a niche product, too expensive, too limited, not what real consumers wanted. That judgment did not age well.
Today, every major automaker is racing to electrify. Many are still struggling to catch up — not only with Tesla, but with Chinese manufacturers who have scaled electric vehicles faster, and more cost-effectively, than anyone in Detroit predicted. EV sales worldwide reached 20.7 million in 2025 — nearly one in four vehicles sold globally. In China, more than half of all new vehicles sold are now electric.
Now, a similar moment may be unfolding in heavy-duty trucking. And once again, the incumbent manufacturers are making arguments that should sound familiar because we have heard them before.
As someone who spent 32 years at the EPA and 18 of them as Director of the Office of Transportation and Air Quality (OTAQ) at the US EPA where I led efforts to reduce emissions from diesel trucks by about 95 percent and the development of the first national greenhouse gas emission standards for medium and heavy-duty trucks, I recognize this playbook.
A Familiar Playbook
When Tesla entered the passenger car market, the legacy auto industry’s objections followed a consistent pattern – cost too high, infrastructure insufficient, customers not ready. Today, the truck industry is making similar arguments and making them in federal court.
The EMA’s legal filing characterizes the standards as an unauthorized mandate forcing a transition to electric vehicles. They were nothing of the sort. They were pollution limits — designed to help Americans breathe cleaner air and live in a safer climate. By aligning with an administration that suggests climate change is a hoax and the U.S. should not take action to reduce carbon pollution, they are telling the public and their customers that they don’t deserve clean air and that the country should rely on diesel and its hazardous emissions when the rest of the world is moving to electrification
Enter the Tesla Semi
And yet, at this very moment, an American company is demonstrating that electric truck is feasible today.
The Wall Street Journal reports that professional truckers who have piloted the Tesla Semi in early deployments are reporting something the legacy industry insists is impossible – an electric Class 8 truck that drivers prefer to diesel. They praise its instant torque at 80,000 pounds, its elimination of blind spots, and a driving experience that reduces fatigue on long hauls. Fleet operators in Southern California are placing orders because the Semi’s 500-mile range enables two to three round trips a day on routes where competing electric trucks max out at 225 miles.
This month, Tesla officially began mass production of the Semi at a dedicated factory near Gigafactory Nevada — with deliveries projected between 5,000 and 15,000 units in 2026, scaling to a target capacity of 50,000 trucks per year.
The economics are striking. Real-world tests show the Tesla Semi costing roughly 15 cents per mile to power — compared to nearly 48 cents per mile for a diesel truck. With diesel surging past $5 a gallon — and prices climbing further — fleet operators are calculating their fuel exposure with urgency. When a technology offers clear, measurable savings on total cost of ownership, fleets move.
The repealed standards were pollution standards — grounded in available technology, designed to clean the air, cut fuel costs for fleets, strengthen energy security, and ensure American truck manufacturers are not left behind in a global market racing toward electrification. Revoking them does not eliminate the forces driving electrification. It simply removes the framework that aligned industry investment with where the market is heading and continues to expose people to diesel emission health impacts.
The Contradiction These Companies Cannot Escape
What makes this moment particularly striking is what Volvo, Daimler, and Traton have said publicly about their own climate commitments. Daimler has pledged carbon neutrality for all new trucks in the U.S., Europe, and Japan by 2039. Volvo Group has committed to 50 percent zero-emission truck sales by 2030. Traton: “We are dedicated to reducing greenhouse gas emissions across the value chain in line with the Paris agreement.”
While America Retreats, the World Accelerates
Roughly 25 percent of China’s new truck sales were electric last year — and it is exporting aggressively into global markets. Europe is tightening CO₂ targets for heavy vehicles. Even as Daimler, Volvo, and Traton lobby Brussels to soften interim milestones, the direction of European policy is clear, and the direction of Chinese competition is clearer still.
This is the same strategic error the American auto industry made in the 1970s. When the oil embargo hit, Detroit kept building large, fuel-intensive vehicles while Toyota, Nissan, and Honda seized the moment and delivered efficiency.
The Human Cost of Delay
Medium and heavy diesel trucks make up less than 6 percent of vehicles on the road but produce more than half the smog-forming pollution and soot Americans breathe. The communities most harmed are low-income neighborhoods and communities of color along diesel freight corridors, the same communities that would benefit most from the clean truck transition the EMA is fighting to block.
I chaired public hearings on diesel pollution at the EPA. I heard from families who lived next to freight yards and along truck routes. I have seen what diesel exhaust does to children’s lungs. The EPA standards that the EMA wants to bury were designed to save lives.
The Choice Ahead
The manufacturers behind this litigation face a strategic choice and history has already run this experiment before.
They can lead the transition — invest early, honor the commitments they made publicly, and compete in a global market that is moving toward electrification whether Washington participates or not. Or they can resist delay investments, fight standards, and wait until the market shifts and the cost of catching up has compounded beyond what any lobbying victory was worth.
The federal government has chosen retreat. But states, cities, and corporate leaders still have choices to make. Governors can protect consumer EV incentives. Mayors can electrify municipal fleets. CEOs can make procurement decisions today that do not wait for Washington to find its way back to science and economics.
We owe that much to the drivers, the communities, and the generations that come after us. And the companies that understand that sooner rather than later will be the ones still standing when the transition arrives in full.
