Tesla is being sued by the nonprofit Environmental Democracy Project over “ongoing failure to comply with the Clean Air Act” at the electric vehicle company’s assembly plant in Fremont, California.
In the suit, filed in a federal court in San Francisco on Monday, the environmental group claimed Tesla has violated the particular law “hundreds of times since January 2021, emitting harmful pollution into the neighborhoods surrounding the Factory.”
While Tesla has long touted the climate benefits of driving EVs, its manufacturing practices have been decried by environmentalists for years. Tesla landed at 89 on the 2023 Toxic 100 Air Polluters list, an annual study by the Political Economy Research Institute at the University of Massachusetts at Amherst. The Environmental Protection Agency fined Tesla $275,000 in 2022, claiming the company had failed to measure, track and maintain records about its own emissions or to minimize air pollutants from painting operations at the facility.
Separately, Tesla was sued by 25 counties in California for its handling of hazardous waste materials at facilities throughout the state earlier this year, and promptly settled with those counties. And in Germany, environmentalists have been protesting Tesla’s clearing of forests to build a factory outside of Berlin, as well as the company’s water consumption.
The latest lawsuit in California described Tesla’s environmental violations as “ongoing” and said that residents and employees in the surrounding area have been exposed to “excess amounts of air pollution, including nitrogen oxides, arsenic, cadmium, and other harmful chemicals.”
Tesla didn’t immediately respond to a request for comment.
The Bay Area Air Quality Management District, an environmental regulator, recently accused Tesla of allowing “unabated emissions” in Fremont that should have been prevented. The agency said Tesla has received 112 violation notices since 2019, and is now seeking an abatement order that would force the company to implement changes to its factory operations.
“The violations are frequent, recurring, and can negatively affect public health and the environment,” the regulator said in a statement earlier this month.
Air pollution from the assembly plant is the result of equipment that frequently breaks down, allowing emissions to vent directly into the air without proper filtration, regulators have said. Additionally, Tesla employees or contractors have allegedly shut off air pollution controls in the factory, particularly when the company was having trouble with other paint shop equipment.
The paint shop is where unpainted vehicle bodies are primed, painted and coated before final assembly. Tesla’s has a history of repeated fires, CNBC previously reported.
In Tesla’s recent quarterly report, the company maintained that its mission is to “accelerate the world’s transition to sustainable energy.”
However, in spearheading a massive reorganization at Tesla of late, CEO Elon Musk has been promoting its research and development efforts on artificial intelligence and self-driving software, robotaxis and humanoid robots, rather than electric cars and solar energy products.
Musk told investors on the company’s first-quarter earnings call to think of Tesla and its value “almost entirely in terms of solving autonomy.” He recently called climate activists “communists,” sharing derisive memes targeting them on X.
Neptune and OpenAI have collaborated on a metrics dashboard to help teams that are building foundation models. The companies will work “even more closely together” because of the acquisition, Neptune CEO Piotr Niedźwiedź said in a blog.
The startup will wind down its external services in the coming months, Niedźwiedź said. The terms of the acquisition were not disclosed.
“Neptune has built a fast, precise system that allows researchers to analyze complex training workflows,” OpenAI’s Chief Scientist Jakub Pachocki said in a statement. “We plan to iterate with them to integrate their tools deep into our training stack to expand our visibility into how models learn.”
OpenAI has acquired several companies this year.
It purchased a small interface startup called Software Applications Incorporated for an undisclosed sum in October, product development startup Statsig for $1.1 billion in September and Jony Ive’s AI devices startup io for more than $6 billion in May.
Neptune had raised more than $18 million in funding from investors including Almaz Capital and TDJ Pitango Ventures, according to its website. Neptune’s deal with OpenAI is still subject to customary closing conditions.
“I am truly grateful to our customers, investors, co-founders, and colleagues who have made this journey possible,” Niedźwiedź said. “It was the ride of a lifetime already, yet still I believe this is only the beginning.”

Micron said on Wednesday that it plans to stop selling memory to consumers to focus on meeting demand for high-powered artificial intelligence chips.
“The AI-driven growth in the data center has led to a surge in demand for memory and storage,” Sumit Sadana, Micron business chief, said in a statement. “Micron has made the difficult decision to exit the Crucial consumer business in order to improve supply and support for our larger, strategic customers in faster-growing segments.”
Micron’s announcement is the latest sign that the AI infrastructure boom is creating shortages for inputs like memory as a handful of companies commit to spend hundreds of billions in the next few years to build massive data centers. Memory, which is used by computers to store data for short periods of time, is facing a global shortage.
Micron shares are up about 175% this year, though they slipped 3% on Wednesday to $232.25.
AI chips, like the GPUs made by Nvidia and AdvancedMicro Devices, use large amounts of the most advanced memory. For example, the current-generation Nvidia GB200 chip has 192GB of memory per graphics processor. Google’s latest AI chip, the Ironwood TPU, needs 192GB of high-bandwidth memory.
Memory is also used in phones and computers, but with lower specs, and much lower quantities — many laptops only come with 16GB of memory. Micron’s Crucial brand sold memory on sticks that tinkerers could use to build their own PCs or upgrade their laptops. Crucial also sold solid-state hard drives.
Micron competes against SK Hynix and Samsung in the market for high-bandwidth memory, but it’s the only U.S.-based memory supplier. Analysts have said that SK Hynix is Nvidia’s primary memory supplier.
Micron supplies AMD, which says its AI chips use more memory than others, providing them a performance advantage for running AI. AMD’s current AI chip, the MI350, comes with 288GB of high-bandwidth memory.
Micron’s Crucial business was not broken out in company earnings. However, its cloud memory business unit showed 213% year-over-year growth in the most recent quarter.
Analysts at Goldman on Tuesday raised their price target on Micron’s stock to $205 from $180, though they maintained their hold recommendation. The analysts wrote in a note to clients that due to “continued pricing momentum” in memory, they “expect healthy upside to Street estimates” when Micron reports quarterly results in two weeks.
A Micron spokesperson declined to comment on whether the move would result in layoffs.
“Micron intends to reduce impact on team members due to this business decision through redeployment opportunities into existing open positions within the company,” the company said in its release.
Microsoft pushed back on a report Wednesday that the company lowered growth targets for artificial intelligence software sales after many of its salespeople missed those goals in the last fiscal year.
The company’s stock sank more than 2% on The Information report.
A Microsoft spokesperson said the company has not lowered sales quotas or targets for its salespeople.
The sales lag occurred for Microsoft’s Foundry product, an Azure enterprise platform where companies can build and manage AI agents, according to The Information, which cited two salespeople in Azure’s cloud unit.
AI agents can carry out a series of actions for a user or organization autonomously.
Less than a fifth of salespeople in one U.S. Azure unit met the Foundry sales growth target of 50%, according to The Information.
In another unit, the quota was set to double Foundry sales, The Information reported. The quota was dropped to 50% after most salespeople didn’t meet it.
In a statement, the company said the news outlet inaccurately combined the concepts of growth and quotas.

“Aggregate sales quotas for AI products have not been lowered, as we informed them prior to publication,” a Microsoft Spokesperson said.
The AI boom has presented opportunities for businesses to add efficiencies and streamline tasks, with the companies that build these agents touting the power of the tools to take on work and allow workers to do more.
OpenAI, Google, Anthropic, Salesforce, Amazon and others all have their own tools to create and manage these AI assistants.
But the adoption of these tools by traditional businesses hasn’t seen the same surge as other parts of the AI ecosystem.
The Information noted AI adoption struggles at private equity firm Carlyle last year, in which the tools wouldn’t reliably connect data from other places. The company later reduced how much it spent on the tools.
