Elon Musk walks the walk by consuming far less carbon than other billionaires
Elon Musk may be trading places with Amazon founder Jeff Bezos these days for the title of the world’s richest person by net worth, but the Tesla and SpaceX CEO also holds a unique place among his fellow billionaires. Based on estimates from anthropologists from Indiana University, Elon Musk may very well be one of the billionaires with the smallest carbon footprint.
Critics of Elon Musk would argue that the Tesla and SpaceX CEO’s carbon footprint is excessive due to his frequent travels with his private jet. However, Richard Wilk, the director of the Open Anthropology Institute at Indiana University, and Beatriz Barros, a Ph.D. candidate in anthropology at Indiana University, noted in an analysis that Musk’s carbon footprint is actually quite small relative to his fellow billionaires. This is because, unlike other billionaires, Musk owns no luxury superyachts or custom-made, sprawling mansions.
Wilk and Barros opted to analyze a number of billionaires from the 2020 Forbes List, particularly those whose consumption is public knowledge. This excluded a good number of the super-rich in Asia and the Middle-East, but it still provided a good sample of billionaires from across the globe. To estimate each billionaire’s carbon footprint, the anthropologists used data from the US Energy Information Administration and Carbon Footprint. Together with some extensive research, this allowed the pair to estimate the annual CO2 emissions of each house, aircraft, yacht, and vehicle publicly declared by each billionaire.
On average, US residents pollute about 15 tons of CO2 per year as of 2018, though the average global footprint per person is smaller at just about 5 tons annually. The 20 billionaires who were included in the study, for their part, contributed an average of 8,190 tons of CO2 in 2018. But even among this list, some billionaires polluted significantly more than others. And as it turned out, those who owned massive luxury yachts tend to consume significantly more than those who did not.
Roman Abramovich, the owner of London’s Chelsea Football Club and a man who made most of his $19 billion fortune trading oil and gas, proved to be the biggest polluter in the anthropologists’ list with at least 33,859 metric tons of CO2 emissions in 2018. This is due in no small part to his luxury superyacht, the Eclipse, which at 162.5 meters bow to stern is practically a small, private cruise ship. He also travels across the globe in a custom-designed Boeing 767 with a 30-seat dining room, as well as his Gulfstream G650 jet. Abramovich also uses two helicopters and a submarine on his yacht. On top of this, the oil and gas magnate boasts several properties, such as a 28-hectare estate in St. Barts that once belonged to David Rockefeller.
Bill Gates, a huge advocate for sustainability, consumes far less carbon than Abramovich, but his emissions still tower over those of Elon Musk. Gates maintains a $127 million estate in Medina, Washington named Xanadu, which covers 6,131 square meters and amenities like a 23-car garage, a 20-person cinema, and 24 bathrooms. Gates also owns a horse farm, four private jets, a seaplane, and several helicopters. The anthropologists estimate that Gates’ annual carbon footprint stands at 7,493 tons, mostly due to his flying.
For his part, Elon Musk owns no yachts, and the CEO has noted that he does not take many vacations. The Tesla and SpaceX CEO was estimated to have a rather billionaire-modest carbon footprint of 2,084 tons in 2018, which was hundreds of times higher than the average American but significantly smaller than his fellow billionaires. Interestingly enough, Musk’s carbon footprint may have also gotten considerably lower as of late, considering that he sold all of his houses in 2020 and he promised to divest his worldly possessions. Ultimately, Musk, who is currently worth about $190 billion or ten times that of billionaires like Abramovich, proves that even the super-rich can make choices to ensure that they live as sustainably as possible.

Elon Musk and Tesla AI Director share insights after empty driver seat Robotaxi rides
The executives’ unoccupied tests hint at the rapid progress of Tesla’s unsupervised Robotaxi efforts.
Tesla CEO Elon Musk and AI Director Ashok Elluswamy celebrated Christmas Eve by sharing personal experiences with Robotaxi vehicles that had no safety monitor or occupant in the driver’s seat. Musk described the system’s “perfect driving” around Austin, while Elluswamy posted video from the back seat, calling it “an amazing experience.”

Elon and Ashok’s firsthand Robotaxi insights
Prior to Musk and the Tesla AI Director’s posts, sightings of unmanned Teslas navigating public roads were widely shared on social media. One such vehicle was spotted in Austin, Texas, which Elon Musk acknowleged by stating that “Testing is underway with no occupants in the car.”
Based on his Christmas Eve post, Musk seemed to have tested an unmanned Tesla himself. “A Tesla with no safety monitor in the car and me sitting in the passenger seat took me all around Austin on Sunday with perfect driving,” Musk wrote in his post.
Elluswamy responded with a 2-minute video showing himself in the rear of an unmanned Tesla. The video featured the vehicle’s empty front seats, as well as its smooth handling through real-world traffic. He captioned his video with the words, “It’s an amazing experience!”
Towards Unsupervised operations
During an xAI Hackathon earlier this month, Elon Musk mentioned that Tesla owed be removing Safety Monitors from its Robotaxis in Austin in just three weeks. “Unsupervised is pretty much solved at this point. So there will be Tesla Robotaxis operating in Austin with no one in them. Not even anyone in the passenger seat in about three weeks,” he said. Musk echoed similar estimates at the 2025 Annual Shareholder Meeting and the Q3 2025 earnings call.
Considering the insights that were posted Musk and Elluswamy, it does appear that Tesla is working hard towards operating its Robotaxis with no safety monitors. This is quite impressive considering that the service was launched just earlier this year.

Starlink passes 9 million active customers just weeks after hitting 8 million
The milestone highlights the accelerating growth of Starlink, which has now been adding over 20,000 new users per day.
SpaceX’s Starlink satellite internet service has continued its rapid global expansion, surpassing 9 million active customers just weeks after crossing the 8 million mark.
The milestone highlights the accelerating growth of Starlink, which has now been adding over 20,000 new users per day.
9 million customers
In a post on X, SpaceX stated that Starlink now serves over 9 million active users across 155 countries, territories, and markets. The company reached 8 million customers in early November, meaning it added roughly 1 million subscribers in under seven weeks, or about 21,275 new users on average per day.
“Starlink is connecting more than 9M active customers with high-speed internet across 155 countries, territories, and many other markets,” Starlink wrote in a post on its official X account. SpaceX President Gwynne Shotwell also celebrated the milestone on X. “A huge thank you to all of our customers and congrats to the Starlink team for such an incredible product,” she wrote.
That growth rate reflects both rising demand for broadband in underserved regions and Starlink’s expanding satellite constellation, which now includes more than 9,000 low-Earth-orbit satellites designed to deliver high-speed, low-latency internet worldwide.
Starlink’s momentum
Starlink’s momentum has been building up. SpaceX reported 4.6 million Starlink customers in December 2024, followed by 7 million by August 2025, and 8 million customers in November. Independent data also suggests Starlink usage is rising sharply, with Cloudflare reporting that global web traffic from Starlink users more than doubled in 2025, as noted in an Insider report.
Starlink’s momentum is increasingly tied to SpaceX’s broader financial outlook. Elon Musk has said the satellite network is “by far” the company’s largest revenue driver, and reports suggest SpaceX may be positioning itself for an initial public offering as soon as next year, with valuations estimated as high as $1.5 trillion. Musk has also suggested in the past that Starlink could have its own IPO in the future.

NVIDIA Director of Robotics: Tesla FSD v14 is the first AI to pass the “Physical Turing Test”
After testing FSD v14, Fan stated that his experience with FSD felt magical at first, but it soon started to feel like a routine.
NVIDIA Director of Robotics Jim Fan has praised Tesla’s Full Self-Driving (Supervised) v14 as the first AI to pass what he described as a “Physical Turing Test.”
After testing FSD v14, Fan stated that his experience with FSD felt magical at first, but it soon started to feel like a routine. And just like smartphones today, removing it now would “actively hurt.”
Jim Fan’s hands-on FSD v14 impressions
Fan, a leading researcher in embodied AI who is currently solving Physical AI at NVIDIA and spearheading the company’s Project GR00T initiative, noted that he actually was late to the Tesla game. He was, however, one of the first to try out FSD v14.
“I was very late to own a Tesla but among the earliest to try out FSD v14. It’s perhaps the first time I experience an AI that passes the Physical Turing Test: after a long day at work, you press a button, lay back, and couldn’t tell if a neural net or a human drove you home,” Fan wrote in a post on X.
Fan added: “Despite knowing exactly how robot learning works, I still find it magical watching the steering wheel turn by itself. First it feels surreal, next it becomes routine. Then, like the smartphone, taking it away actively hurts. This is how humanity gets rewired and glued to god-like technologies.”
The Physical Turing Test
The original Turing Test was conceived by Alan Turing in 1950, and it was aimed at determining if a machine could exhibit behavior that is equivalent to or indistinguishable from a human. By focusing on text-based conversations, the original Turing Test set a high bar for natural language processing and machine learning.
This test has been passed by today’s large language models. However, the capability to converse in a humanlike manner is a completely different challenge from performing real-world problem-solving or physical interactions. Thus, Fan introduced the Physical Turing Test, which challenges AI systems to demonstrate intelligence through physical actions.
Based on Fan’s comments, Tesla has demonstrated these intelligent physical actions with FSD v14. Elon Musk agreed with the NVIDIA executive, stating in a post on X that with FSD v14, “you can sense the sentience maturing.” Musk also praised Tesla AI, calling it the best “real-world AI” today.
