Our Mission
ACR creates confidence in the integrity of carbon markets to catalyze transformational climate results.
We engage actively in a broad range of industry initiatives to help shape the continuous development and growth of high-integrity carbon markets
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 the independent verification of GHG emission reduction and removals projects
Our Role
ACR is a leading carbon crediting standard operating in global regulated 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.
Our team
ACR benefits from the expertise of a 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 of project registration and verification process through to 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.
