Director, Industrial Programs


Mary Jane Coombs, Director of ACR Industrial Programs, leads a team focused on projects to reduce greenhouse gas emissions from landfills, livestock, ozone-depleting substances, and foam-blowing agents.

Mary Jane joined ACR after over 15 years at the California Air Resources Board (CARB), where she oversaw implementation of CARB’s methane emissions reduction programs for landfills and livestock, as well as electricity-related greenhouse gas emissions reduction programs. Prior to that, she managed allowance allocation, emissions leakage protection, and electricity policy for California’s Cap-and-Trade Program (also at CARB).

Mary Jane has advised jurisdictions around the world on cap-and-trade program design. Before CARB, she was a project manager for the West Coast Regional Carbon Sequestration Partnership, which characterized geological and terrestrial sequestration opportunities in the western United States. She also worked for the U.S. Geological Survey, editing and co-authoring papers on mineral resources.

Mary Jane has a Bachelor of Arts in Geology & Environmental Studies from Whitman College and a Master of Science in Marine Science (studies in paleoclimatology) from the University of California, Santa Barbara.

Our Team

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.
