Patagonia founder Yvon Chouinard stopped by the Fast Company HQ recently with his longtime friend and travel partner Tom Brokaw to talk about sustainable business. It's a subject he knows well, thanks to his years of innovation at Patagonia as well as his experience founding the organization One Percent for the Planet, an alliance of companies that pledge to donate 1% of revenues to environmental charities. When companies give back to save the planet, says Chouinard, it's essentially green marketing.
