Carbon Catalog is a free and independent directory of carbon credits, listing 142 carbon providers and 643 projects worldwide.

Carbon credits neutralize a company's or individual's contribution to global warming. The carbon emissions are balanced out by funding projects which cause an equal reduction in emissions elsewhere.

Get started with our Carbon Guide, including How to Buy and the Carbon Glossary.

Find a carbon credit provider in Europe, North America, Australia or Asia.

View projects certified under the Clean Development Mechanism, Gold Standard or Voluntary Carbon Standard.

Or search our directory for projects based on solar power, wind energy, biomass, industrial methane and more...
