To rank the Greenest Companies in America Newsweek partnered with three independent organizations to assemble a 'green score' for each company. That score is based on three components:
* The Environmental Impact Score, compiled by Trucost, is based on more than 700 metrics, including greenhouse-gas emissions, water use and solid-waste disposal.
* The 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.
* The Reputation Score is based on a survey of academics, environmental officers and CEOs.

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.
