Walmart to cut GHG in supply chain by 20 million tons by 2015

“Carbon is a cost. If we can remove carbon from a supply chain, ultimately they become more competitive. If they can use less energy in the manufacturing of the product, or if the consumer uses less energy, they are certainly reducing their costs or putting dollars in the pockets of their customer,” said Walmart SVP of Sustainability Matt Kistler. Results of their efforts will be audited by outside companies.

They also plan to go to 100% renewable energy.

They’re serious about this. Not so much because they want to hug trees but because it saves them money and resources. That how cleantech and renewable energy will be become mainstream in the capitalist business world. Because they gain by doing so.
