At Gap, responsibility is in style. From 2003 to 2008, the retailer cut greenhouse-gas emissions 20%. And since admitting to child-labor violations in its factories earlier this decade, the company has received high marks from watchdogs for cleaning up the floors and being transparent about its efforts. "We've shifted our focus from policing," says Dan Henkle, Gap's social-responsibility czar, "to consulting with our suppliers to make sure problems don't arise."
