Microsoft is buying tons of carbon removal from Xprize startup Vaulted Deep

techcrunch.com Tim De Chant 2025-07-23 00:03:19

Microsoft is building data centers as fast as it can, and that’s killing its carbon balance sheet. Since 2020, its carbon emissions have grown by nearly a quarter, undermining the pledge it made that year to remove more carbon from the atmosphere than it generates by 2030. So Microsoft has been buying massive amounts of carbon-removal credits to attempt to remedy that situation, including a newly announced purchase of 4.9 million metric tons from Vaulted Deep. Neither party disclosed the financ

Meet the cement transport ship that makes cement ingredients while sailing

Shipping has a pollution problem, but one company has a solution that does more than just eliminate a boat’s carbon dioxide. London-based Seabound has developed a carbon capture system that transforms CO 2 from the engine into limestone, a key ingredient in cement. Fittingly, the company has installed it aboard the UBC Cork, a cement carrier currently sailing through the Mediterranean Sea. When the ship docks in Norway, the limestone created from the voyage will be offloaded and used to make m

We have a surprising underwater ally in combatting climate change: zooplankton

engadget.com Unknown 2025-08-08 00:06:14

Odds are you aren't too familiar with the group of animals called zooplankton, which include copepods, krill and salps. On land, they're most commonly used as fish food. Underwater, however, they've been quietly making a substantial contribution to slowing global warming. The BBC reported on the latest research into zooplankton by an international team, published in the journal Limnology and Oceanography , that detailed just how much these tiny critters have been impacting the planet's temperatu

Frontier is helping Arbor build a “vegetarian rocket engine” to power data centers

Frontier, the organization backed by Stripe, Google, and Meta, announced Tuesday it is paying startup Arbor Energy to remove 116,000 tons of carbon dioxide by the end of the decade. The deal gives Arbor $41 million to help it build its first commercial-scale power plant in southern Louisiana that will burn waste biomass to generate electricity for a data center. At the same time, it’ll sequester the resulting CO 2 , shipping it via pipeline to be buried deep underground. “We are able to market

Tulum Energy rediscovered a forgotten hydrogen tech and used it to raise $27M

techcrunch.com Tim De Chant 2025-08-09 16:00:00

It was a mistake that was ahead of its time. Between 2002 and 2005, engineers with the Techint Group were trying to dial in a new electric arc furnace for a steelmaker when they noticed something odd. The carbon electrodes, rather than breaking down, were growing larger. The team had inadvertently created what’s known as a pyrolysis reaction, which is basically burning something in the absence of oxygen. In this case, the furnace was splitting methane into pure hydrogen and pure carbon. The te

Google’s carbon emissions just went up again

Google’s carbon emissions jumped yet again as the company continues to push ahead in AI. The company’s 2025 sustainability report emphasizes that its “ambition-based emissions” grew 11 percent last year to reach 11.5 million metric tons of carbon dioxide pollution, marking a 51 percent increase compared to 2019. That puts Google farther away from its goal of slashing planet-heating pollution in half by 2030 compared to a 2019 baseline. But what it calls “ambition-based” emissions excludes certa

Factories have used fossil fuels to process iron ore for three centuries, and the climate has paid a heavy price: According to the International Energy Agency, the steel industry today accounts for 8% of carbon dioxide emissions. But it turns out there is a less carbon-intensive alternative: using hydrogen. Unlike coal or natural gas, which release carbon dioxide as a by-product, this process releases water.

Scientists Just Found Something Unbelievably Grim About Pollution Generated by AI

Tech companies are hellbent on pushing out ever more advanced artificial intelligence models — but there appears to be a grim cost to that progress. In a new study in the science journal Frontiers in Communication, German researchers found that large language models (LLM) that provide more accurate answers use exponentially more energy — and hence produce more carbon — than their simpler and lower-performing peers. In other words, the findings are a grim sign of things to come for the environme

Using the Ocean to Suck Up CO2 Could Come With the Small, Unintended Side Effect of Wiping Out Marine Life

As global temperatures soar and emissions remain higher than ever, scientists are exploring the dramatic, planet-wide interventions we could take to stave off the climate crisis. One of the most intriguing possibilities involves using the ocean, already the world's largest carbon sink, to suck up even more of the greenhouse gas by removing some of the carbon that it already stores. Dozens of startups are already experimenting with this form of climate intervention, which is sometimes referred

Methane Pollution Has Cheap, Effective Solutions That Aren’t Being Used

This story originally appeared on Vox and is part of the Climate Desk collaboration. Odorless and colorless, methane is a gas that is easy to miss—but it’s one of the most important contributors to global warming. It can trap up to 84 times as much heat as carbon dioxide in the atmosphere, though it breaks down much faster. Measured over 100 years, its warming effect is about 30 times that of an equivalent amount of carbon dioxide. That means that over the course of decades, it takes smaller a

The new phone brings an impressively thin and light design along with a 6.7-inch display. It also has the S25 Ultra’s 200MP main camera. Unfortunately, this thin and light phone comes with several compromises, such as no telephoto camera and 25W wired charging power.

The real reason why oil and gas companies are bullish on carbon capture

Two years ago, oil and gas company Occidental bought carbon capture startup Carbon Engineering. The transaction was hailed as a win-win: A climate tech company scored a significant exit, and a fossil fuel company gained a foothold in a sector that could be worth up to $150 billion by 2050. Now we have a better idea why Occidental was keen to pick up the pricey technology: They want to use it to pump more oil.
