İn 2009, Wal-Mart received the Aspen Institute Energy and Environment award for Corporate Energy Efficiency. To build on this success, Wal-Mart just announced its new sustainability goal: to eliminate 20 million metric tons of greenhouse gases from the supply chain by 2015. This amount, roughly equivalent to the company’s total corporate emissions last year, is “the equivalent of taking more than 3.8 million cars off the road for a year.”
Wal-Mart’s latest environmentally-friendly initiative builds on several years of its investment in energy efficiency and renewable energy. Wal-Mart introduced three goals in 2005: to be supplied 100 percent by renewable energy; to create zero waste; and to sell products that sustain people and the environment. Their work accelerated in 2006 when Wal-Mart made a big push to go organic and embrace other environmentally friendly policies.
