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.

Nvidia CEO Jensen Huang explains difference between Tesla FSD and Alpamayo
“Tesla’s FSD stack is completely world-class,” the Nvidia CEO said.
NVIDIA CEO Jensen Huang has offered high praise for Tesla’s Full Self-Driving (FSD) system during a Q&A at CES 2026, calling it “world-class” and “state-of-the-art” in design, training, and performance.
More importantly, he also shared some insights about the key differences between FSD and Nvidia’s recently announced Alpamayo system.
Jensen Huang’s praise for Tesla FSD
Nvidia made headlines at CES following its announcement of Alpamayo, which uses artificial intelligence to accelerate the development of autonomous driving solutions. Due to its focus on AI, many started speculating that Alpamayo would be a direct rival to FSD. This was somewhat addressed by Elon Musk, who predicted that “they will find that it’s easy to get to 99% and then super hard to solve the long tail of the distribution.”
During his Q&A, Nvidia CEO Jensen Huang was asked about the difference between FSD and Alpamayo. His response was extensive:
“Tesla’s FSD stack is completely world-class. They’ve been working on it for quite some time. It’s world-class not only in the number of miles it’s accumulated, but in the way it’s designed, the way they do training, data collection, curation, synthetic data generation, and all of their simulation technologies.
“Of course, the latest generation is end-to-end Full Self-Driving—meaning it’s one large model trained end to end. And so… Elon’s AD system is, in every way, 100% state-of-the-art. I’m really quite impressed by the technology. I have it, and I drive it in our house, and it works incredibly well,” the Nvidia CEO said.
Nvidia’s platform approach vs Tesla’s integration
Huang also stated that Nvidia’s Alpamayo system was built around a fundamentally different philosophy from Tesla’s. Rather than developing self-driving cars itself, Nvidia supplies the full autonomous technology stack for other companies to use.
“Nvidia doesn’t build self-driving cars. We build the full stack so others can,” Huang said, explaining that Nvidia provides separate systems for training, simulation, and in-vehicle computing, all supported by shared software.
He added that customers can adopt as much or as little of the platform as they need, noting that Nvidia works across the industry, including with Tesla on training systems and companies like Waymo, XPeng, and Nuro on vehicle computing.
“So our system is really quite pervasive because we’re a technology platform provider. That’s the primary difference. There’s no question in our mind that, of the billion cars on the road today, in another 10 years’ time, hundreds of millions of them will have great autonomous capability. This is likely one of the largest, fastest-growing technology industries over the next decade.”
He also emphasized Nvidia’s open approach, saying the company open-sources its models and helps partners train their own systems. “We’re not a self-driving car company. We’re enabling the autonomous industry,” Huang said.
