Adam Werbach is the co-founder of sharing startup Yerdle, formerly chief sustainability officer for Saatchi & Saatchi and president of the Sierra Club. He is the author of Strategy for Sustainability: A Business Manifesto. More
Werbach was elected president of the Sierra Club at the age of 23, which seemed ridiculous to everyone, including him. In 2005 he controversially began consulting for Walmart on their journey towards sustainability. He later sold his firm to Saatchi & Saatchi, where he directed their global sustainability practice, working with some of the largest corporations in the world to bring sustainability into the core of their businesses and seeking projects that might tip the scales towards humanity's survival. He lives in San Francisco and Bolinas, California.
