A new study from the University of California (UC) Berkeley shows a steady, albeit modest, decline in carbon emissions with increased electric vehicle (EV) adoption over the last few years.
The research looks at carbon emission trends between 2018 and 2022, utilizing data from 50 air-quality sensors throughout the Bay Area, as detailed in a report published in the Environmental Science and Technology journal on Thursday.
The data shows a gradual decline in carbon dioxide emissions, representing a 1.8-percent yearly decrease on average, according to the study’s Lead Researcher and Professor, Executive Associate Dean at Berkeley’s College of Computing, Data Science and Society, Ronald Cohen in a report from the San Francisco Chronicle.
“If we do it for 20 years, it’s a big number,” Cohen said.
Researchers reported the highest levels of carbon dioxide near highway corridors, and while 1.8 percent may not seem like much, Cohen adds that a 3.5 percent annual reduction would be enough to reach California’s 2045 carbon neutrality target.
Along with using the sensors to gather data, the study examined registration data from the California Department of Motor Vehicles (DMV) to monitor the ratio of EVs on the road to gas cars.
The researchers found the data to remain true even when considering other potential factors, including the reduction of motor vehicle traffic during the early days of the COVID-19 pandemic and other seasonal influences. Still, the researchers concluded that the decrease in emissions is due to the increase in hybrid and battery-electric vehicle (BEV) use, as fuel-efficiency standards tighten.
Cohen also notes that the majority of carbon dioxide emissions come from the transportation sector, as well as wintertime heating and heavy industry such as oil refineries. Part of the goal of the study was to determine if data shows that clean transportation policies actually make a difference, “so people could put energy into climate policies that really work.”
While the sensors also monitored other pollutants, including particulates and nitrogen oxide, Cohen says this particular study was focused on measuring carbon dioxide emissions. This study, he adds, was the first to look at a larger area and make a connection between a decline in carbon emissions and EV adoption.
According to Cohen, the findings also represent a more powerful connection between the adoption of EVs and reduced emissions than he initially thought it would.
“That’s the big win,” Cohen added.
BEV sales in the U.S. reached 1.1 million units in 2023, according to Cox Automotive data, with California, Washington, New Jersey, Connecticut and Texas making up the top five adopters. Globally, the International Energy Agency (IEA) expects EV adoption to increase tenfold by 2030, under current goals set by governments around the world.

Tesla Robotaxi ride-hailing without a Safety Monitor is proving to be a difficult task, according to some riders who made the journey to Austin to attempt to ride in one of its vehicles that has zero supervision.
Last week, Tesla officially removed Safety Monitors from some — not all — of its Robotaxi vehicles in Austin, Texas, answering skeptics who said the vehicles still needed supervision to operate safely and efficiently.
BREAKING: Tesla launches public Robotaxi rides in Austin with no Safety Monitor
Tesla aimed to remove Safety Monitors before the end of 2025, and it did, but only to company employees. It made the move last week to open the rides to the public, just a couple of weeks late to its original goal, but the accomplishment was impressive, nonetheless.
However, the small number of Robotaxis that are operating without Safety Monitors has proven difficult to hail for a ride. David Moss, who has gained notoriety recently as the person who has traveled over 10,000 miles in his Tesla on Full Self-Driving v14 without any interventions, made it to Austin last week.
He has tried to get a ride in a Safety Monitor-less Robotaxi for the better part of four days, and after 38 attempts, he still has yet to grab one:
Wow just wow!
It’s 8:30PM, 29° out ice storm hailing & Tesla Robotaxi service has turned back on!
Waymo is offline & vast majority of humans are home in the storm

Tesla said last week that it was rolling out a controlled test of the Safety Monitor-less Robotaxis. Ashok Elluswamy, who heads the AI program at Tesla, confirmed that the company was “starting with a few unsupervised vehicles mixed in with the broader Robotaxi fleet with Safety Monitors,” and that “the ratio will increase over time.”
This is a good strategy that prioritizes safety and keeps the company’s controlled rollout at the forefront of the Robotaxi rollout.
However, it will be interesting to see how quickly the company can scale these completely monitor-less rides. It has proven to be extremely difficult to get one, but that is understandable considering only a handful of the cars in the entire Austin fleet are operating with no supervision within the vehicle.
Tesla has given its biggest hint that Full Self-Driving in Europe is imminent, as a new feature seems to show that the company is preparing for frequent border crossings.
Tesla owner and influencer BLKMDL3, also known as Zack, recently took his Tesla to the border of California and Mexico at Tijuana, and at the international crossing, Full Self-Driving showed an interesting message: “Upcoming country border — FSD (Supervised) will become unavailable.”
FSD now shows a new message when approaching an international border crossing.

Due to regulatory approvals, once a Tesla operating on Full Self-Driving enters a new country, it is required to comply with the laws and regulations that are applicable to that territory. Even if legal, it seems Tesla will shut off FSD temporarily, confirming it is in a location where operation is approved.
This is something that will be extremely important in Europe, as crossing borders there is like crossing states in the U.S.; it’s pretty frequent compared to life in America, Canada, and Mexico.
Tesla has been working to get FSD approved in Europe for several years, and it has been getting close to being able to offer it to owners on the continent. However, it is still working through a lot of the red tape that is necessary for European regulators to approve use of the system on their continent.
This feature seems to be one that would be extremely useful in Europe, considering the fact that crossing borders into other countries is much more frequent than here in the U.S., and would cater to an area where approvals would differ.
Tesla has been testing FSD in Spain, France, England, and other European countries, and plans to continue expanding this effort. European owners have been fighting for a very long time to utilize the functionality, but the red tape has been the biggest bottleneck in the process.
Tesla Europe builds momentum with expanding FSD demos and regional launches
Tesla operates Full Self-Driving in the United States, China, Canada, Mexico, Puerto Rico, Australia, New Zealand, and South Korea.

SpaceX Starship V3 gets launch date update from Elon Musk
The first flight of Starship Version 3 and its new Raptor V3 engines could happen as early as March.
Elon Musk has announced that SpaceX’s next Starship launch, Flight 12, is expected in about six weeks. This suggests that the first flight of Starship Version 3 and its new Raptor V3 engines could happen as early as March.
In a post on X, Elon Musk stated that the next Starship launch is in six weeks. He accompanied his announcement with a photo that seemed to have been taken when Starship’s upper stage was just about to separate from the Super Heavy Booster. Musk did not state whether SpaceX will attempt to catch the Super Heavy Booster during the upcoming flight.
The upcoming flight will mark the debut of Starship V3. The upgraded design includes the new Raptor V3 engine, which is expected to have nearly twice the thrust of the original Raptor 1, at a fraction of the cost and with significantly reduced weight. The Starship V3 platform is also expected to be optimized for manufacturability.
The Starship V3 Flight 12 launch timeline comes as SpaceX pursues an aggressive development cadence for the fully reusable launch system. Previous iterations of Starship have racked up a mixed but notable string of test flights, including multiple integrated flight tests in 2025.
Interestingly enough, SpaceX has teased an aggressive timeframe for Starship V3’s first flight. Way back in late November, SpaceX noted on X that it will be aiming to launch Starship V3’s maiden flight in the first quarter of 2026. This was despite setbacks like a structural anomaly on the first V3 booster during ground testing.
“Starship’s twelfth flight test remains targeted for the first quarter of 2026,” the company wrote in its post on X.
