Wal-Mart has 3 long term global sustainability goals:

• to produce zero waste
• to operate with 100 per cent renewable energy
• to make environmentally preferable products available

In Canada, to achieve these goals, their new outlets opening in 2009 will be designed to save 30% in energy use. These new stores would be called Wal-Mart HE (high-efficiency). And over 5 years, the HE stores would save Wal-Mart $25 million.

Wal-Mart HE stores would achieve these energy savings by:

• using waste energy from refrigerators to help heat stores
• cutting lighting costs
• covering roofs with white membranes to reflect sunlight and lower summer cooling costs
• reducing the size of the buildings

Wal-Mart also has their sustainability initiatives, partnerships and products showcased at their "For the Greener Good" website. Their products page outlines new eco-friendly products broken down by various categories.
