Adam Werbach CEO, Saatchi & Saatchi; Former President, Sierra Club; Commissioner, San Francisco Public Utilities Commission

A lot has happened since Adam Werbach declared environmentalism dead in a speech to The Commonwealth Club three years ago. In 2007, Werbach's sustainability agency Act Now helped Wal-Mart engage its 1.3 million employees in one of the largest grassroots sustainability movements to date - the Personal Sustainability Project. In January 2008, Act Now was acquired by Saatchi & Saatchi, a hothouse for world-changing ideas with over 7,000 employees in 84 countries. Together they aim to become the sustainability agency of record for the world's leading corporations. Their purpose: help companies grow their businesses and preserve the planet through strategy, product and supply-chain innovation, workforce engagement and marketing. The mission: create a consumer revolution for social change.
