Carbon credit trading platforms are marketplaces and exchanges where organizations buy, sell or retire carbon credits. Buyers include companies offsetting residual emissions, project developers and traders. Vendors are listed A–Z with no scores or rankings; see our methodology for how vendors are included.
Ranked by verified data once available. Until then companies are shown A–Z. Paid placements are labeled Sponsored and never change the order.
A carbon credit typically represents one tonne of CO2 equivalent reduced or removed by a project, issued under a registry or standard.
Compliance markets are created by regulation and cover regulated emitters, while voluntary markets let organizations buy credits for their own climate goals.
Check which registries and standards the credits come from, how project information and verification are disclosed, fees, and how retirement is recorded.
Review the project's methodology, additionality, permanence, verification and registry records, and the standard it is certified under.
