DACLab says it can remove CO2 using less electricity than many competitors

techcrunch.com Tim De Chant 2025-09-22 15:00:00

The world’s countries may have pledged to cut its carbon pollution, but with global emissions reaching an all-time high last year they’ve fallen far short. Digging out of that hole is going to require removing carbon straight from the atmosphere. But it comes with a hefty price tag, mostly because of the energy required. Removing one metric ton of CO 2 using direct air capture is expected to require around 2,000 kWh of electricity when the technology is sorted and scaled up. One startup called

Big Businesses Are Doing Carbon Dioxide Removal All Wrong

wired.com Joseph Winters 2025-09-30 03:00:00

This story originally appeared on Grist and is part of the Climate Desk collaboration. Achieving net-zero greenhouse gas emissions by 2050 will require removing carbon dioxide from the atmosphere, according to the Intergovernmental Panel on Climate Change, the world’s foremost authority on the topic. But only some types of carbon removal are actually effective—and these are largely not the kind that major companies are investing in. A new report from the NewClimate Institute, a European think

New pathway engineered into plants lets them suck up more CO₂

arstechnica.com Unknown 2025-10-01 19:09:00

Lots of people are excited about the idea of using plants to help us draw down some of the excess carbon dioxide we've been pumping into the atmosphere. It would be nice to think that we could reforest our way out of the mess we're creating, but recent studies have indicated there's simply not enough productive land for this to work out. One alternative might be to get plants to take up carbon dioxide more efficiently. Unfortunately, the enzyme that incorporates carbon dioxide into photosynthes

Apple isn't making any carbon neutral claims with its Series 11 smartwatch

Apple hosted its "Awe dropping" iPhone event today, but wearables also got their moment in the sun, including the announcement of the Apple Watch Series 11 . In recent years, the company has made some big environmental claims around its smartwatches, but after facing some legal scrutiny overseas, the language for this new Apple Watch generation's green cred is notably more muted.

Scientists Turned Plastic Trash Into a Material That Eats Carbon

Experts estimate that the global production and disposal of plastics emits nearly 2 billion tons of greenhouse gases per year. The vast majority of these materials end up in landfills, but what if we could repurpose some of that waste to remove planet-warming emissions from the atmosphere? A team of researchers in Denmark has discovered a way to do just that.

If any single event was a watershed for conservation of the world's mangrove forests, it was the Indian Ocean tsunami of 2004. The day after Christmas that year, a magnitude 9.1 earthquake thundered along a fault line on the ocean floor with a force that sent waves — some a hundred feet high — surging toward the densely populated coasts encircling the Indian Ocean.

This Unlikely Chemical Could Be a Powerful Weapon Against Climate Change

Year after year, humans pump more carbon dioxide (CO2) into the atmosphere than nature can remove, fueling global warming. As the need to mitigate climate change becomes increasingly urgent, scientists are developing ways to actively remove CO2 from the atmosphere in addition to cutting emissions. One of the biggest hurdles to scaling current carbon capture technologies is the vast amount of energy they consume, but what if there was an alternative that uses an abundant, cheap power source?

Huge Parts of the North Sea Seabed Are Upside Down, New Study Reveals

The North Sea, however, has revealed giant mounds of sand that defy this geological principle on a scale scientists have never seen before.

Processing the seaweed into other consumer products is possible, but inadvisable given that the health risks of doing so have not yet been sufficiently studied. “I believe that sargassum’s purpose is to produce energy, because when it decomposes, it releases many heavy metals such as arsenic, lead, and cadmium,” Amaro says. “Therefore it is better to produce biofuels or bi
