Walmart. Coca-Cola. BP. Toyota. The world economy runs on the profits of transnational corporations. Politicians need their backing. Nonprofits rely on their philanthropy. People look to their brands for meaning. And their power continues to rise. Now, facing a mounting global environmental crisis, can big business provide the solutions? Absolutely, the CEOs are responding: big business not only has the global power, in-house guidelines for corporate social responsibility will ensure it happens, voluntarily. Really? Peter Dauvergne agrees that our crisis would be worse without the recent increase in corporate recycling, energy efficiency, and smart packaging. Yet he holds his applause, arguing that big business is still doing far more to destroy, than protect, our planet. In his judgment trusting big business to lead sustainability is unwise, perhaps even catastrophic. Planetary sustainability will require reining in the power of big business, starting now.
