Here is a snippet that was written yesterday by Reuters entitled Wal-Mart pushing Chinese suppliers to go green:

Wal-Mart Stores Inc will meet with its thousands of Chinese suppliers
this fall as part of a big push to reduce waste and emissions at
factories that make its products, Chief Executive Lee Scott said on
Thursday.

The company's top priorities in China will be to address the
appropriate disposal of waste as well as to make reductions in both
waste and greenhouse gas emissions. It will also work on reducing
packaging and boosting energy efficiency, much as it has in its U.S.
business, Scott said.

Wal-Mart has pushed its suppliers to cut back on the amount of packaging they use by 5 percent by 2013.

Wal-Mart is also working with its suppliers to make the most "energy
intensive" products in its stores 25 percent more energy efficient
within three years. By 2010, the retailer also wants all its flat-panel
TVs to be 30 percent more energy efficient.
