"Aside from Walmart itself, there is no louder and more enthusiastic cheerleader for the retail giant’s sustainability campaign than Environmental Defense Fund. A quick perusal of the news over the last few weeks finds EDF issuing a press release about Walmart’s green leadership, praising its environmental boldness in a Fortune interview, backing its solar claims in a Fast Company article, and headlining a live chat about Walmart hosted by The Guardian."
"EDF, one of the nation’s largest and best-known environmental organizations, is Walmart’s right-hand man in the green game. It turns out, unlike most Walmart jobs, that’s a pretty lucrative gig to have.
Since 2005, EDF has received $66 million from the Walton Family Foundation. The Waltons are the children and grandchildren of Walmart founder Sam Walton. The crucial thing to know about the family — in addition to their mind-boggling wealth, estimated at $145 billion — is that they control Walmart. They not only have several seats on the company’s board, including the chair. They own over half of Walmart’s stock."
