Greenest Companies In The U.S. Ranked By Newsweek

This week, Newsweek released its 2011 Green Rankings of the greenest companies in the world and in the U.S.

They say they looked past the "green chatter" and compiled a list that compares "actual environmental footprints, management (policies, programs, initiatives, controversies), and reporting practices of big companies." For their rankings, Newsweek teamed up with two research partners, Trucost and Sustainalytics.

Below, check out the slideshow of Newsweek's list of the 15 greenest companies in the U.S., out of surveys of the country's 500 biggest companies. For more information about their methodology, click here.

In other rankings, Johnson & Johnson and Intel were the only two U.S. companies to make the 2011 Global 100 list of the world's 100 most sustainable corporations.

Even though they aren't on this list, Frito-Lay also says they are making efforts to become more green. The company has reduced its carbon footprint by 50 percent at its "near net zero" manufacturing facility in Arizona.
