A new report shows that commercial vehicles are much higher polluters than passenger vehicles despite making up a much smaller portion of cars on U.S. roads. For this reason, the study’s authors say the U.S. should prioritize electrifying the commercial vehicles sector rather than just focusing on passenger vehicles.
PepsiCo- and KPMG-backed software logistics company Adiona Tech shared the Connected Thinking report on Tuesday, which suggests that last-mile combination trucks be electrified as soon as possible to help fight CO2 emissions. The company says that all urban deliveries of groceries, parcels, furniture and other goods should be performed by electric vehicles (EVs) by 2025.
“Commercial vehicles are a much bigger polluter than passenger cars and they are in desperate need of modernization,” Adiona writes in the report. “Large combination trucks are just 1 percent of vehicles on the road, but they produce 18 percent of vehicle emissions.”
The study compared Bureau of Transportation Statistics figures from 2019 to those of 2020 and 2021, looking at vehicle miles driven by passenger cars and trucks, along with their associated emissions. What it found was that emissions decreased significantly in 2020 and 2021, while truck miles and their associated emissions increased above 18 percent of road traffic emissions.

The report included several key findings, notably including that the average fuel consumption of combination trucks is roughly 20 times higher than that of a passenger vehicle. The report also says that switching just five of these combination trucks to green alternatives — such as hydrogen fuel cells or lithium batteries — would be comparable to the effects of buying EVs for 100 households.
While the average truck drives about 22,930 miles annually, the report notes that large combination trucks travel an average of 59,929 miles in the same period, and single-unit trucks only average 12,278 miles annually.
According to data sourced from the Bureau of Transportation, light-duty vehicles with a short wheelbase have an average fuel consumption of 481 gallons per year, compared to 640 gallons consumed on average by light-duty vehicles with long wheelbases, and 1,639 gallons on average by single-unit, two-axle trucks with six tires or more. However, the data also shows that combination trucks consume an average of 9,909 gallons annually.
In a press release, Adiona Tech CEO Richard Savoie highlights the need to prioritize larger freight in the fight against carbon emissions, beginning with those that travel the most.
“America needs to aggressively decarbonize the biggest emitters on the road, large freight and delivery vehicles,” Savoie said in the release. “The US automotive industry is at a crossroads, but it needs to act now to electrify every car on the road. Doing so requires connected thinking and collective action. We cannot transform the national fleet of nearly 300 million vehicles overnight, so we need to make decisions that make the biggest difference, for the lowest effort first.”
The passenger vehicle sector has adopted EVs much more quickly than others, as several automakers have now followed Tesla’s lead in building fully electric vehicles. While electrifying every car is still an important goal, Savoie explains, it shouldn’t be the only one.
“Frankly, the data shows that consumer adoption of EVs should not be America’s number one priority,” Savoie said. “Electrifying fleets is by far the most efficient way to reduce vehicle emissions. Every battery we put in a combination truck counts for 20 households buying an EV, and businesses often have fleets of hundreds of vehicles.”
“We must prioritize the electrification of these vehicles that are on the road most, travel the longest distances, and are the least fuel-efficient,” Savoie added.
Several companies have begun piloting or at least stated plans to purchase electric last-mile delivery vehicles, including FedEx, Amazon, Walmart and more.
Adiona Tech backer PepsiCo is one of the first companies to have begun electrifying its semi-truck fleet after purchasing an initial batch of Tesla Semis last year. A recent event showed some serious range results for the Semi, and PepsiCo detailed last month how the truck was helping it reach its own sustainability goals.

Tesla Optimus Gen 3 is coming to the Tesla Diner with new ambitions
Tesla’s Optimus robot left the Hollywood Diner within months of opening. Now Musk is planning its return with a bigger role and a major Gen 3 upgrade underway.
Tesla’s Optimus robot was one of the most talked-about features when the Tesla Diner opened on Santa Monica Boulevard in Hollywood on July 21, 2025. Dubbed “Poptimus” by Tesla fans, the Gen 2 robot stood upstairs at the retro-futuristic, drive-in theater and Tesla Supercharging station, scooping popcorn into bags and handing them to guests with a wave.
The diner itself had been years in the making. Elon Musk first floated the idea in 2018 with a tweet about building an “old-school drive-in, roller skates & rock restaurant” at a Hollywood Supercharger. What eventually opened was a unique two-story neon-lit space, with 80 EV charging stalls, and Optimus serving as a live demonstration of where Tesla’s ambitions were headed.
If our retro-futuristic diner turns out well, which I think it will, @Tesla will establish these in major cities around the world, as well as at Supercharger sites on long distance routes.

But Optimus did not stay long, and was gone by December 2025.
Now, the robot is set to return with a more demanding job. Musk has ambitions for Optimus to take on a food runner role in 2026, delivering meals directly to cars at the Supercharger stalls. While the latest Gen 3 Optimus is likely to initially take on its previous popcorn-serving role, it wouldn’t be out of the question for Optimus to see a quick promotion. With improved hand dexterity that features 50 total actuators and 22 degrees of freedom per hand, and significantly more powerful processing through Tesla’s latest AI5 chip that includes Grok-powered voice interaction, Musk described Optimus at the Abundance Summit on March 12, 2026, as “by far the most advanced robot in the world, Nothing’s even close.”

That confidence is backed by a major manufacturing shift. At the Q4 2025 earnings call in January, Musk announced Tesla would discontinue the Model S and Model X and convert those Fremont production lines to build Optimus. “It’s time to basically bring the Model S and X programs to an end,” he said, calling for a pivot that reflects where the Tesla’s future lies.

Musk forces Judge’s exit from shareholder battles over viral social media slip-up
McCormick insisted in a court filing that she harbors no actual bias against Musk or the defendants. She claimed she either never clicked the “support” button, LinkedIn’s version of a “like,” or did so accidentally.
Many Tesla fans are familiar with the name Kathaleen McCormick, especially if they are investors in the company.
McCormick is a Delaware Chancery Court Judge who presided over Tesla CEO Elon Musk’s pay package lawsuit over the past few years, as well as his purchase of Twitter. However, she will no longer be sitting in on any issues related to Musk.
Elon Musk demands Delaware Judge recuse herself after ‘support’ post celebrating $2B court loss
In a rare admission of potential optics issues in one of America’s most powerful corporate courts, Delaware Chancery Court Chancellor Kathaleen McCormick stepped aside Monday from a cluster of shareholder lawsuits targeting Elon Musk and Tesla’s board.
The move came just days after Musk’s legal team highlighted her apparent “support” on LinkedIn for a post that mocked the billionaire over his 2022 tweets about the $44 billion Twitter acquisition.
McCormick insisted in a court filing that she harbors no actual bias against Musk or the defendants. She claimed she either never clicked the “support” button, LinkedIn’s version of a “like,” or did so accidentally.
She wrote in a newly published memo from the Delaware Chancery Court:
“The motion for recusal rests on a false premise — that I support a LinkedIn post about Mr. Musk, which I do not in fact support. I am not biased against the defendants in these actions.”
Yet she granted the reassignment anyway, acknowledging that the intense media scrutiny surrounding her involvement had become “detrimental to the administration of justice.”
The consolidated cases will now be handled by three of her colleagues on the Delaware Court of Chancery, the nation’s go-to venue for high-stakes corporate disputes. The lawsuits accuse Musk and Tesla directors of breaching fiduciary duties through lavish executive compensation and lax governance oversight.
One prominent claim, filed by a Detroit pension fund, challenges massive stock awards granted to board members, alleging the payouts harmed the company. The litigation also overlaps with issues stemming from Musk’s turbulent 2022 Twitter purchase.
McCormick’s history with Musk made her a lightning rod. In 2022, she presided over the fast-tracked lawsuit that ultimately forced Musk to complete the Twitter deal after he tried to back out.
Then in 2024, she struck down his record $56 billion Tesla compensation package, ruling the approval process was flawed and overly CEO-friendly. The Delaware Supreme Court later reinstated the pay on technical grounds, but the ruling fueled Musk’s long-standing criticism of the state’s judiciary.
Musk has repeatedly urged companies to reincorporate elsewhere, arguing Delaware courts have grown hostile to visionary leaders. Monday’s recusal hands him a symbolic victory and underscores how personal social-media activity can collide with judicial impartiality standards.
Delaware law requires judges to step aside if there’s even a “reasonable basis” to question their neutrality.
Court watchers say the episode highlights growing tensions in corporate America’s legal epicenter. While McCormick maintained her impartiality, the appearance of bias proved too costly to ignore. The cases will proceed without her, but the broader debate over Delaware’s dominance in business litigation is far from over.

Elon Musk has generous TSA offer denied by the White House: here’s why
Musk stepped in on March 21 via a post on X, writing: “I would like to offer to pay the salaries of TSA personnel during this funding impasse that is negatively affecting the lives of so many Americans at airports throughout the country.”
Tesla and SpaceX CEO Elon Musk made a generous offer to pay the salaries of Transportation Security Administration (TSA) employees last week, but the offer was denied by the White House.
In a striking display of private-sector initiative clashing with federal bureaucracy, the White House has turned down an offer from Elon Musk to personally cover the salaries of TSA officers amid an ongoing partial government shutdown. The rejection, reported last Wednesday by multiple outlets, highlights the legal and political hurdles facing unconventional solutions to Washington’s funding gridlock.
The impasse began weeks ago when Congress failed to pass funding for the Department of Homeland Security (DHS), leaving TSA employees, essential workers who screen millions of travelers daily, without paychecks while still required to report for duty.
Frustrated travelers have endured record-long security lines at major airports, with reports of chaos and delays rippling across the country.

But it was not for no reason.
White House spokesperson Abigail Jackson responded on behalf of the Trump administration, expressing appreciation for Musk’s gesture.
However, the legal obstacles, which would be insurmountable, would inhibit Musk from doing so. Jackson said:
“We greatly appreciate Elon’s generous offer. This would pose great legal challenges due to his involvement with federal government contracts.”
Musk’s companies hold significant federal contracts, including NASA launches through SpaceX and potential Defense Department work, raising concerns about conflicts of interest, ethics rules, and anti-bribery statutes that prohibit private payments to government employees. Administration officials also indicated they expect the shutdown to end soon, making external funding unnecessary.
The episode underscores deeper tensions in Washington. Musk, who has advised on government efficiency efforts and maintains a close relationship with President Trump, has frequently criticized wasteful spending and bureaucratic delays.
His offer came as airport security lines ballooned, drawing public frustration toward both parties. TSA officers, many of whom rely on paychecks to cover mortgages and family expenses, have continued working without compensation, a situation that has drawn bipartisan concern but little immediate resolution.
Critics of the rejection argue it prioritizes red tape over practical relief for frontline workers and travelers. Supporters of the White House position counter that allowing private funding sets a dangerous precedent and could undermine congressional authority over the budget.
The White House eventually came to terms with the TSA on Friday and started paying them once again, and lines at airports instantly shrank. The Department of Homeland Security (DHS) said that TSA staf would begin receiving paychecks “as early as” today.
