Last month Newsweek published its 2011 Green Rankings, evaluating how green the world's largest companies truly are. According to the original release, Our Green Rankings, fully posted at Newsweek.com/green, comprise two lists, one that surveys the 500 biggest companies in America and another of the 500 largest companies in the world. Both highlight firms that are leading -- or lagging -- in environmental performance. The data -- crunched in cooperation with Trucost and Sustainalytics, two leading environmental-research firms -- assess companies' environmental footprint (including greenhouse-gas emissions and water use); management (including environmental policies, programs, and initiatives); and disclosure (including company reporting and involvement in transparency initiatives).
