Climeworks

Climeworks develops and operates Direct Air Capture (DAC) plants to remove CO₂ from the atmosphere on a gigaton scale by 2050. It runs the world’s two largest operational Direct Air Capture plants in Iceland, powered exclusively by renewable energy. By partnering with storage specialists such as Carbfix, Climeworks ensures the permanent removal of captured CO₂ safely stored underground for thousands of years. Its carbon removal via Direct Air Capture is verified and certified by independent third parties DNV and Puro.earth, ensuring utmost transparency and trust.

SeaGen

SeaGen's mission is to mitigate and remove carbon emissions using seaweed. They believe that the wonders of seaweed can be coupled with technology for ocean rehabilitation of biodiversity, removal of pollution, and deacidification, that will also create a fantastic base biomass for food, fertilizer, plastics, fuel, carbon removal, and much much more.

Charm Industrial

Charm Industrial is a group of smart, integrity-rich Bay Area engineers, on a mission to get atmospheric carbon concentrations down to 280 ppm (pre industrial levels). If you’ve ever looked at the stars and said “what if I could just put the oil back in the ground?” Well, now you can. They create injectable bio-oil from waste products and store it safely underground.

greenSand

greenSand converts CO₂ into lime when it comes into contact with rainwater. This is a natural process called weathering. It is comparable to the rusting of iron. Mother Earth has been cleaning up its own CO₂ emissions for millions of years. greenSand has developed products of olivine-rich rocks that can replace sand and stone in applications such as walking paths, parking spaces, and potting soil.

CarbonCure

Carbon XPRIZE Grand Prize Winner CarbonCure is a Canadian-based company focused on mineralizing captured CO₂ in concrete. With more than 650 systems sold across the global concrete industry and a methodology verified by Verra, CarbonCure’s technologies currently save from the atmosphere thousands of metric tons of CO₂ each month – with significant growth and impact, year-over-year. Did you know the concrete you build your home with can be part of solving climate change?

CarbonBuilt

CarbonBuilt's Carbon XPRIZE-winning technology reduces concrete’s embodied carbon by 70% to over 100% — enabling immediate impact in thousands of existing plants without compromising price, performance, or operations. First, they remove carbon-intensive cement from the mix and replace it with local industrial waste materials. Then they trap atmospheric CO₂ inside the blocks while curing.

Patch

Patch is the platform that powers climate action. With an API and a marketplace that enables companies to seamlessly purchase as little as a gram to thousands of tonnes of carbon removal from reputable and trusted carbon removal projects, Patch enables people and business to take action against climate change.
