We operate a transparent online registry system to record the issuance, transfer, and retirement of serialized carbon credits
We pioneer rigorous, peer-reviewed, science-based carbon accounting standards and methodologies
We oversee the registration and independent verification of greenhouse gas emission reduction and removals projects
ACR is a leading carbon crediting program operating in global compliance and voluntary carbon markets.
Founded in 1996 as the first private voluntary GHG registry in the world, we have a quarter century of expertise in ensuring carbon credit quality and a proven track record in innovation and continuous improvement.
ACR benefits from a responsive, best-in-class team with wide-ranging expertise, including carbon project development, climate policy, carbon market design, carbon credit methodology development, third-party verification, and registry design and operations. We understand the complex technical, market and regulatory issues involved in developing carbon projects and work with asset owners to navigate the process from project registration and verification through to the issuance of carbon credits.
ACR is governed by Environmental Resources Trust LLC, a wholly-owned nonprofit subsidiary of Winrock International. The ERT Board of Managers ensures ACR maintains focus on harnessing the power of markets to improve the environment.
