About Carbon Catalog

Carbon Catalog is an independent directory of carbon offsets. Our mission is to increase the level of trust and information in the voluntary carbon market. We offer:

• Comprehensive directory of providers who sell carbon offsets. Each provider is rated on transparency and the quality of projects they support.
• Details of the carbon projects supported by providers.
• The Carbon Catablog, our blog for carbon offset buyers.
• Carbon offset guide including an introduction and glossary.
• A free widget for other sites to embed our listings.

Carbon Catalog is a free service which has no commercial interest. Our transparent listings and ratings follow objective guidelines for providers. We apologize for any errors or omissions, but accept no legal responsibility.

Carbon Catalog was founded by Gideon Greenspan and launched in September 2007. You can contact us here.
