ACR creates confidence in the integrity of carbon markets to catalyze transformational climate results.
Founded in 1996 as the first private voluntary GHG registry in the world, ACR has a quarter century of expertise in ensuring carbon credit quality and a proven track record in innovation and continuous improvement.
As a leading global carbon crediting program operating in global compliance and voluntary carbon markets, ACR engages actively in a broad range of industry initiatives to help shape the development and growth of high-integrity carbon markets. We pioneer rigorous, peer-reviewed, science-based carbon accounting standards and methodologies. We operate a transparent online registry system to record the issuance, transfer, and retirement of serialized carbon credits. We oversee the registration and independent verification of greenhouse gas emission reduction and removals projects.
ACR is a non-profit enterprise of Winrock International.
