To produce the 2012 Green Rankings, Newsweek collaborated with two leading environmental research providers, Trucost and Sustainalytics, to assess each company’s environmental footprint, management of that footprint and transparency. The Green Rankings focus on the largest publicly traded companies in America and worldwide. Each list consists of the largest 500 companies by revenue (most recent fiscal year), market capitalization and number of employees, as of April 30, 2012. A number of the largest U.S.-based companies appear on both lists.
