Michael Brune holds degrees in economics and finance from West Chester University in Pennsylvania and came to the Sierra Club from the Rainforest Action Network, where he served seven years as executive director. Under Mr. Brune’s leadership, Rainforest Action Network won more than a dozen key environmental commitments from America’s largest corporations. During his tenure as the Sierra Club’s executive director, the organization has grown to more than 3.5 million supporters, and its Beyond Coal campaign has been recognized as one of the most effective in environmental history. His critically acclaimed book, Coming Clean: Breaking America’s Addiction to Oil and Coal (2010), details a plan for a new green economy that will create good-paying jobs, promote environmental justice, and bolster national security. He and his wife, Mary, attribute their ongoing passion for environmental activism in part to concern that their children inherit a healthy world.
