Turn CO₂ into art with CΛRBONLock White
Chalk that removes CO₂ from the air
Atierra's CΛRBONLock White is a fine white chalk powder that blends seamlessly with various art mediums, adding texture and depth to your creations. Made by removing CO₂ from the air, it forms when CO₂-rich air is bubbled through a calcium hydroxide solution, transforming into calcium carbonate—chalk. Once dried, this CO₂-absorbed chalk is ready to bring your art to life, turning pollution into thought-provoking creations.

More about our Air-to-Art Project
Carbon Removal Partners Remove CO₂ from the Air
CO₂ levels, now over 400 ppm, are at their highest in 400,000 years, fueling global warming. Carbon removal is crucial to eliminate and lock away the CO₂ already accumulated in our atmosphere. At Atierra, we partner with pioneering companies that remove CO₂ from the air and transform it into stable forms like carbon and calcium carbonate.
Artists Utilize Mediums Made from CO₂ to Create Expressive Artwork
Artists purchase these materials from our platform to create carbon-removed paintings, sketches, and sculptures. By incorporating these materials, their creations not only lock away carbon dioxide but also inspire further climate action through meaningful dialogue about the importance of climate solutions.
Atierra Certifies Artists Using CO₂-Derived Materials in Their Art
Atierra is currently developing protocols to verify artists who utilize materials made from CO₂ in their artwork. Once verified, artists will receive certification, enabling them to sell their pieces at a premium to passionate collectors.
Art Collectors Acquire Carbon-Removed Masterpieces
Artists sell their carbon-removed creations on our platform to passionate collectors. By purchasing and showcasing these works, art collectors actively take climate action while creating demand for the artists' creations and the materials provided by Atierra's partners, collectively advancing carbon removal efforts.
