Michael Brune, a leading national environmentalist for 25+ years (including as Executive Director of the Sierra Club for 12 years and of the Rainforest Action Network before that), has led some of the most effective environmental advocacy initiatives in U.S. history, including the Sierra Club’s massively successful Beyond Coal campaign, which resulted in the retirement of more than two-thirds of U.S. coal-fired power plants. Brune currently directs the Larsen Lam Climate Change Foundation and advises several other NGOs and early-stage clean energy companies, and he also serves on the boards of SOLARCYCLE and Outdoor Afro.
