The Newsweek Green Rankings grade America's 500 largest publicly traded companies, as measured by revenue, market capitalization and number of employees, on their environmental performance, policies and reputation as environmentally responsible companies.
Newsweek partnered with three independent organizations to assemble a "green score" for each company. That score is based on three components:
* An Environmental Impact Score, compiled by Trucost, is based on more than 700 metrics, including greenhouse-gas emissions, water use and solid-waste disposal.To calculate a company's overall ranking, the three component scores were standardized, combined using a weighted average (45 percent for the Environmental Impact Score, 45 percent for the Green Policies Score, and 10 percent for the Reputation Survey) and mapped to a 100-point scale.
* A Green Policies Score is based on data collected by MSCI ESG Research and reflects an analytical assessment of a company's environmental policies and initiatives.
* A Reputation Score is based on a survey of academics, environmental officers and CEOs.
