The only company to make both U.S. and world lists, IBM has long been committed to environmental responsibility. The company employs roughly 426,750 people, and had about $99.9 billion in revenue in 2010. In 1971, IBM formalized (PDF) a corporate environmental policy—designed to make IBM an environmental leader in all its business activities. And in the intervening 40 years, many of the company’s environmental initiatives truly have been ahead of their time. For instance, IBM developed requirements (PDF) for secondary containment for underground storage tanks in 1979, while the EPA waited until 1985 to create the Office of Underground Storage Tanks.
