Choose Better Carbon Credits
Calyx Global rates carbon credits. Our ratings tell you how much you can rely on a credit’s claims of impact on CO2/climate, biodiversity, communities, and more. With Calyx Ratings, you can find and use carbon credits that make a real difference for the planet and for people, and protect yourself from financial and reputational risk.
Greenhouse Gas Integrity Risk Ratings
Calyx Greenhouse Gas (GHG) Ratings assess the risk that credits do not represent one ton of removed or reduced CO2 – as they are supposed to.
Sustainable Development Goal Impact Ratings
Calyx Sustainable Development Goal (SDG) Impact Ratings evaluate project claims of impact on UN Sustainable Development Goals.
