Newsweek compares the actual environmental footprints; management performance, including policies, initiatives and controversies; and reporting practices of the 500 largest US companies in constructing this list. It partnered with two leading environmental research organizations, Trucost and Sustainalytics, to develop the rankings.
"It's obvious to me the hard work and dedication of our employees was the main reason why our company scored a significant improvement in Newsweek's assessment of 'green' companies," said C. Larry Pope, president and CEO of Smithfield Foods. "But that said, we're certainly not satisfied. Our mission is to be the most socially responsible food producer that we can be, and we strive for continual improvement.”
