Retail giant Wal-mart Stores Inc. has announced a goal to eliminate 20 million metric tons of greenhouse gas (GHG) emissions from its global supply chain by the end of 2015. This represents one and a half times the company's estimated global carbon footprint growth over the next five years and is the equivalent of taking more than 3.8 million cars off the road for a year.
"Energy efficiency and carbon reduction are central issues in the world today," says Mike Duke, Walmart's president and CEO. "We've been working to make a difference in these areas, both in our own footprint and our supply chain. We know that we have an opportunity to do more and the capacity to do more."
