IBM  has been recognized for the second consecutive year as the greenest company in the country, according to the Newsweek 2012 Green Rankings survey. A panel of independent judges ranked major companies based on numerous criteria, including their environmental impact, environmental management and sustainability disclosure. IBM was one of 500 large U.S. organizations evaluated.

The report notes that IBM’S Smarter Planet products and services help clients measure and reduce their resource consumption while saving money. It points to a system developed at the company’s Zurich Research Lab, where water that cools a supercomputer is used to warm nearby buildings.

Wayne Balta (Vice President,  Corporate Environmental Affairs and Product Safety, IBM): Environmental sustainability benefits our clients, our company and the planet, and we are constantly striving for continual improvement.

Other tech companies that made top fifteen include Cognizant, Microsoft, EMC, Intel, NVIDIA, CA Technologies, Dell, Sprint Nextel, and HP.
