World’s leading crediting platform for engineered carbon removal

We are on a mission to mobilize the economy to reward carbon net negative emissions. We help voluntary corporate buyers accelerate carbon dioxide removal (CDR) at an industrial global scale. We do this through the Puro Standard, the world’s first standard focused solely on carbon removal that durably stores carbon from the atmosphere for 100+ years.
