Green-e is the nation's leading independent certification and verification program for renewable energy and greenhouse gas emission reductions in the retail market. It has two certification and one verification programs: Green-e Climate is a voluntary certification program launched in 2008 that sets consumer-protection and environmental-integrity standards for greenhouse gas (GHG) emission reductions sold in the voluntary market. Green-e® Climate was launched in February 2008 by CRS as the first and only independent, third-party certification program for retail carbon offsets sold in the voluntary market. It ensures that Certified Offsets meet the highest standards for environmental quality and are sold and delivered as advertised. Green-e Climate supplements other voluntary standards organizations—including The Verified Carbon Standard (VCS), The Gold Standard, The Climate Action Reserve (CAR), and the American Carbon Registry (ACR)—which serve the market as project standards and certification programs aimed at ensuring valid, verified supply of real emissions reductions to the market.
