A new study from UC Berkeley confirms what EV fans already know: EV adoption does, in fact, make the air cleaner. Perhaps even more importantly, the study offers some quantifiable, granular data about how much electric vehicles are impacting emission rates in the here and now, not in the foreseeable future.
Not that these numbers will blow you away, mind you, but still, it’s good news.
Researchers from the University of California, Berkeley, found that between 2018 and 2022, CO2 emission from all sources (industries, homes, traffic) across the San Francisco Bay Area dropped around 1.8% per year – a difference the researchers attribute to widespread EV adoption in the area. For vehicle emission rates, those numbers dropped 2.6% annually. EVs made up nearly 40% of new auto registrations in San Jose and 34% in San Francisco last year.
“We show from atmospheric measurements that adoption of electric vehicles is working, that it’s having the intended effect on CO2 emissions,” said Ronald Cohen, a University of California Berkeley chemistry professor and senior author of the study. The study was published this week in the journal Environmental Science & Technology.
Researchers were able to track that data via a network of sensors around the Bay Area that monitor both CO2 and five critical air pollutants: carbon monoxide, nitrous oxides (NO and NO2), ozone, and particulates (PM 2.5).
According to the research, by comparing the air pollution and CO2 data, the sensors help determine the emission source. The sensors are also unique in that they track CO2, which is not a pollutant regulated by the Clean Air Act and not picked up by Environmental Protection Agency sensors – the EPA of course does track CO2 but not as an air pollutant.
To get to their results, the researchers divided the emissions captured by the sensors into three categories: industry, such as refineries, which churn out a steady stream of emissions; seasonable varying emissions, like home heating and cooling; and traffic. After isolating the traffic emissions, researchers were able to link a dip traffic emissions to the rise in EVs, hybrids, and vehicles with better fuel efficiency.
While the sensors have been in place for more than a decade, it’s taken time to analyze the findings – and one could argue a while for EVs to reach a critical mass to trigger a difference. Looking at the data, the researchers also saw a drop in emissions during the pandemic.
The network of 50 sensors, set up in 2012 by Cohen, make up what’s called the Berkeley Environmental Air Quality & CO2 Network (BEACO2N), a system that has already been adopted by Providence, Rhode Island, and Glasgow, Scotland, to track their city air pollution. Around 70% of global CO2 emissions come from cities, yet few urban areas have granular data about where those emissions originate.
Another study last year, published by Keck School of Medicine at the University of Southern California, found similar results looking at emissions in California. That study tracked real-world pollution levels, electric car penetration, and emergency room visits across California between 2013 and 2019, and controlled against overall improvements in California air quality during the study period.
Electrek’s Take
Of course, any optimism is tempered by the reality that, to meet California and Bay Area carbon reduction goals, the yearly decrease needs to be much greater – twice what it is now. California has a goal to reach net-zero emissions by 2045, and Cohen says that we need emissions to drop 3.7% per year to reach that. Still, the onus isn’t only on traffic emissions. Home and industry emissions need to drop too, and making that happen requires policies.

At least 5 Waymo self-driving I-Pace electric cars were set on fire amid protests that turned violent in Los Angeles this weekend.
It could represent as much as 5% of Waymo’s fleet in Los Angeles being destroyed.
The United States Immigration and Customs Enforcement (ICE) launched several raids in the Los Angeles area last week that triggered large-scale protests across the city over the weekend.
The protests were mostly peaceful and aimed to bring attention to federal agents indiscriminately arresting and detaining people, but in some cases, they were violent clashes with the police.

Things took a turn for the worse with President Trump calling the National Guard.
There have been several instances of rioting, looting, and general property damage.
In a unique case, it appears that one or more rioters purposely called multiple Waymo vehicles to Arcadia and Alameda streets, where they slashed the vehicles’ tires, broke the windows, and wrote anti-ICE messages on them.
At around 5 PM on Sunday, the Waymo vehicles were set on fire:
With the ongoing protests, the fire department couldn’t get access to the vehicles and they eventually completely burned down:
Waymo is believed to be operating a fleet of about 100 self-driving cars in the Los Angeles area. Therefore, a significant percentage of the fleet was burned down today.
The company completes over 120,000 rides per week in California, but it operates a bigger fleet in the Bay Area and covers a big service area than in LA.
The company currently operates over 1,500 vehicles across San Francisco, Los Angeles, Phoenix, and Austin.
With a high utilization rate, the relatively small fleet has already taken significant market shares of those ride-hailing markets. It is estimated that Waymo accounts for approximately 20% of the ride-hailing market in San Francisco.
The new vehicles are going to enable Waymo to expand into new markets.

The Taihuttus on a ski trip to Sierra Nevada in southern Spain. They sold everything they owned in 2017 to bet on bitcoin — and now travel full-time as a family of five.
Didi Taihuttu
A wave of high-profile kidnappings targeting cryptocurrency executives has rattled the industry — and prompted a quiet security revolution among some of its most visible evangelists.
Didi Taihuttu, patriarch of the so-called “Bitcoin Family,” said he overhauled the family’s entire security setup after a string of threats.
The Taihuttus — who sold everything they owned in 2017, from their house to their shoes, to go all-in on bitcoin when it was trading around $900 — have long lived on the outer edge of crypto ideology. They travel full-time with their three daughters and remain entirely unbanked.
Over the past eight months, he said, the family ditched hardware wallets in favor of a hybrid system: Part analog, part digital, with seed phrases encrypted, split, and stored either through blockchain-based encryption services or hidden across four continents.
“We have changed everything,” Taihuttu told CNBC on a call from Phuket, Thailand. “Even if someone held me at gunpoint, I can’t give them more than what’s on my wallet on my phone. And that’s not a lot.”
CNBC first reported on the family’s unconventional storage system in 2022, when Taihuttu described hiding hardware wallets across multiple continents — in places ranging from rental apartments in Europe to self-storage units in South America.
The Taihuttu family dressed up for Halloween in Phuket, Thailand, where they recently moved homes after receiving disturbing messages pinpointing their location from YouTube videos.

As physical attacks on crypto holders become more frequent, even they are rethinking their exposure.
This week, Moroccan police arrested a 24-year-old suspected of orchestrating a series of brutal kidnappings targeting crypto executives.
One victim, the father of a crypto millionaire, was allegedly held for days in a house south of Paris — and reportedly had a finger severed during the ordeal.
In a separate case earlier this year, a co-founder of French wallet firm Ledger and his wife were abducted from their home in central France in a ransom scheme that also targeted another Ledger executive.
Last month in New York, authorities said, a 28-year-old Italian tourist was kidnapped and tortured for 17 days in a Manhattan apartment by attackers trying to extract his bitcoin password — shocking him with wires, beating him with a gun, and strapping an Apple AirTag around his neck to track his movements.
The common thread: The pursuit of crypto credentials that enable instant, irreversible transfers of virtual assets.
“It is definitely frightening to see a lot of these kidnappings happen,” said JP Richardson, CEO of crypto wallet company Exodus. He urged users to take security into their own hands by choosing self-custody, storing larger sums on hardware wallets, and — for those holding significant assets — exploring multi-signature wallets, a setup typically used by institutions.
Richardson also recommended spreading funds across different wallet types and avoiding large balances in hot wallets to reduce risk without sacrificing flexibility.
That rising sense of vulnerability is fueling a new demand for physical protection with insurance firms now racing to offer kidnap and ransom (K&R) policies tailored to crypto holders.
But Taihuttu isn’t waiting for corporate solutions. He’s opted for complete decentralization — of not just his finances, but his personal risk profile.
As the family prepares to return to Europe from Thailand, safety has become a constant topic of conversation.
“We’ve been talking about it a lot as a family,” Taihuttu said. “My kids read the news, too — especially that story in France, where the daughter of a CEO was almost kidnapped on the street.”
Now, he said, his daughters are asking difficult questions: What if someone tries to kidnap us? What’s the plan?
One of the steel plates the Taihuttu family uses to store part of their bitcoin seed phrase. Didi etched it by hand using a hammer and letter punch — part of a decentralized storage system spread across four continents.
Didi Taihuttu
Though the girls carry only small amounts of crypto in their personal wallets, the family has decided to avoid France entirely.
“We got a little bit famous in a niche market — but that niche is becoming a really big market now,” Taihuttu said. “And I think we’ll see more and more of these robberies. So yeah, we’re definitely going to skip France.”
Even in Thailand, Taihuttu recently stopped posting travel updates and filming at home after receiving disturbing messages from strangers who claimed to have identified his location from YouTube vlogs.
“We stayed in a very beautiful house for six months — then I started getting emails from people who figured out which house it was. They warned me to be careful, told me not to leave my kids alone,” he said. “So we moved. And now we don’t film anything at all.”
“It’s a strange world at the moment,” he said. “So we’re taking our own precautions — and when it comes to wallets, we’re now completely hardware wallet-less. We don’t use any hardware wallets anymore.”
To throw off would-be attackers, Didi Taihuttu encrypts select words from each 24-word seed phrase — then splits the phrases into four sets of six and hides them around the world.
Didi Taihuttu
The family’s new system involves splitting a single 24-word bitcoin seed phrase — the cryptographic key that unlocks access to their crypto holdings — into four sets of six words, each stored in a different geographic location. Some are kept digitally through blockchain-based encryption platforms, while others are etched by hand into fireproof steel plates using a hammer and letter punch, then hidden in physical locations across four continents.
“Even if someone finds 18 of the 24 words, they can’t do anything,” Taihuttu explained.
On top of that, he’s added a layer of personal encryption, swapping out select words to throw off would-be attackers. The method is simple, but effective.
“You only need to remember which ones you changed,” he said.
Part of the reason for ditching hardware wallets, Taihuttu said, was a growing mistrust of third-party devices. Concerns about backdoors and remote access features — including a controversial update by Ledger in 2023 — prompted the family to abandon physical hardware altogether in favor of encrypted paper and steel backups.
While the family still holds some crypto in “hot” wallets — for daily spending or to run their algorithmic trading strategy — those funds are protected by multi-signature approvals, which require multiple parties to sign off before a transaction can be executed.
The Taihuttus use Safe — formerly Gnosis Safe — for ether and other altcoins, and similarly layered setups for bitcoin stored on centralized platforms like Bybit.

Didi Taihuttu
About 65% of the family’s crypto is locked in cold storage across four continents — a decentralized system Taihuttu prefers to centralized vaults like the Swiss Alps bunker used by Coinbase-owned Xapo. Those facilities may offer physical protection and inheritance services, but Taihuttu said they require too much trust.
“What happens if one of those companies goes bankrupt? Will I still have access?” he said. “You’re putting your capital back in someone else’s hands.”
Instead, Taihuttu holds his own keys — hidden across the globe. He can top up the wallets remotely with new deposits, but accessing them would require at least one international trip, depending on which fragments of the seed phrase are needed. The funds, he added, are intended as a long-term pension to be accessed only if bitcoin hits $1 million — a milestone he’s targeting for 2033.
The shift toward multiparty protections extends beyond just multi-signature. Multi-party computation, or MPC, is gaining traction as a more advanced security model.
Didi, Romaine, and their three daughters live largely off-grid, managing crypto through decentralized exchanges, algorithmic trading bots, and a globally distributed cold storage system.
Didi Taihuttu
Instead of storing private keys in one place — a vulnerability known as a “single point of compromise” — MPC splits a key into encrypted shares distributed across multiple parties. Transactions can only go through when a threshold number of those parties approve, sharply reducing the risk of theft or unauthorized access.
Multi-signature wallets require several parties to approve a transaction. MPC takes that further by cryptographically splitting the private key itself, ensuring that no single individual ever holds the full key — not even their own complete share.
The shift comes amid renewed scrutiny of centralized crypto platforms like Coinbase, which recently disclosed a data breach affecting tens of thousands of customers.
Taihuttu, for his part, says 80% of his trading now happens on decentralized exchanges like Apex — a peer-to-peer platform that allows users to set buy and sell orders without relinquishing custody of their funds, marking a return to crypto’s original ethos.
While he declined to reveal his total holdings, Taihuttu did share his goal for the current bull cycle: a $100 million net worth, with 60% still held in bitcoin. The rest is a mix of ether, layer-1 tokens like solana, link, sui, and a growing number of AI and education-focused startups — including his own platform offering blockchain and life-skills courses for kids.
Lately, he’s also considering stepping back from the spotlight.
“It’s really my passion to create content. It’s really what I love to do every day,” he said. “But if it’s not safe anymore for my daughters … I really need to think about them.”

The rare-earth miner MP Materials will enjoy growing strategic value to the U.S., as geopolitical tensions with China make the supply of critical minerals more uncertain, according to Morgan Stanley.
The investment bank upgraded MP Materials to the equivalent of a buy rating with a stock price target of $34 per share, implying 32% upside from Friday’s close.
MP Materials owns the only operating rare earth mine in the U.S. at Mountain Pass, California. China dominates the global market for rare earth refining and processing, according to Morgan Stanley.
“Geopolitical and trade tensions are finally pushing critical mineral supply chains to top of mind,” analysts led by Carlos De Alba told clients in a Thursday note. “MP is the most vertically integrated rare earths company ex-China.”
Beijing imposed export restrictions on seven rare earth elements in April in response to President Donald Trump’s tariffs. It has kept those restrictions in place despite trade talks with U.S.
Trump removed some restrictions Wednesday on the Defense Production Act, which could allow the federal government to offer an above market price for rare earths. MP Materials is the best positioned company to benefit from this, according to Morgan Stanley. Its shares rose more than 5% on Thursday.
MP Materials is developing fully domestic rare earth supply chain in the U.S. and plans to begin commercial production of magnets used in most electric vehicle motors, offshore wind wind turbines, and the future market for humanoid robots, according to Morgan Stanley.
The investment bank expects MP Materials to post negative free cash flow this year and in 2026, but the company has a strong balance sheet should accelerate positive free cash flow from 2027 onward.
