Our Team

ACR’s expertise is unmatched by our peers. Our team of professionals has over 250 years of collective experience in environmental and carbon markets working in offset project development, climate policy, offset methodology development, offset project verification and registry operations. We understand the complex technical, market and regulatory issues involved in developing offset projects and work with carbon asset owners to navigate the project registration and verification process through to issuance of carbon credits.

As a wholly-owned nonprofit subsidiary of Winrock International, ACR is governed by the Board of the Environmental Resources Trust (ERT).
