Working With the Enemy

Once the youngest president of the Sierra Club, Adam Werbach used to call Wal-Mart toxic. Now the company is his biggest client. Does the path to a greener future run through Bentonville?

Fast Company, September 1, 2007 — “To this day, they won't speak to me," says Adam Werbach. His clients--or rather, his old clients--fired him when word got out last year that he was doing work for Wal-Mart (NYSE:WMT). Of course, many people make compromises to do business with the largest company in the world--accept lower profit margins, absorb relentless performance pressure. But for Werbach, 34, a lifelong environmentalist, the cost of working with Wal-Mart has been personal. Some of his old friends don't speak to him. His former colleagues think he's sold out.
