Leaders in Environmental Justice, Labor, Green Finance, and Climate Policy Join the CGC Board

Washington, DC— The Coalition for Green Capital proudly announces the election of four new members to its board of directors: Julie Greene Collier, William G. Demas, David J. Hayes, and Cecilia Martinez. Reed Hundt, CEO and Chairman of the Board stated, “We are honored to welcome four distinguished individuals to our board of directors. They will play a critical role in our governance, not only in conjunction with our applications for funding under the Greenhouse Gas Reduction Fund but also in managing any awards we may receive from the Environmental Protection Agency (EPA).”

Julie Greene Collier, Chief of Staff of the AFL-CIO said, “I am pleased to bring the labor perspective directly into board decision-making. I look forward to expanding our organized workforce, needed to implement CGC’s vision and focus on underserved and low-income communities.”

William G. Demas, Head of Green Investments, Americas, Macquarie Asset Management, said, “I am honored to join the CGC board. I look forward to applying my almost two decades of green investing experience to ensure the prudent management of any EPA capitalization grant.”

David J. Hayes who returned to the CGC board after serving in the White House as Special Assistant to the President for Climate Policy and who served as the Deputy Secretary and Chief Operating Officer at the U.S. Department of the Interior in two previous administrations, reflected on the remarkable progress made in building a national network for clean energy investment during his absence. He said, “I am very pleased to rejoin the CGC board. I am not only impressed by the progress and national network built since my departure but also am hopeful that tens of billions of dollars of additional clean power investment, focused on low-income and disadvantaged communities, lies in the immediate future of CGC.”

Cecilia Martinez, the Chief of Environmental and Climate Justice at Bezos Earth Fund, said, “It is with a sense of excitement and hope that I join the CGC board. In my experience in environmental and climate justice, including serving as the Senior Director for Environmental Justice at the White House Council on Environmental Quality in the Biden Administration, I know firsthand the need for tens of billions of dollars in investments for vulnerable and overburdened communities. This is essential to deliver a just transition to the new clean power economy.”

The Coalition for Green Capital is thrilled to introduce these four exceptional leaders who have joined the board of directors before the forthcoming Greenhouse Gas Reduction Fund application submission. With their expertise spanning environmental justice, labor advocacy, effective administration of governmental funding, and green finance, these new board members will play a pivotal role in building a sustainable and equitable future.
