I’m not one to ignore the evidence.
Wal-Mart’s board has actually committed to three environmental goals for the retail giant:
In an October, 2005, speech titled “Twenty-First Century Leadership,” Wal-Mart committed to three large sustainability goals: to be supplied 100 percent by renewable energy, to create zero waste, and to sell products that sustain our resources and the environment. The company set goals of increasing fuel efficiency in Wal-Mart’s truck fleet by 25 percent over the next three years, and doubling it within 10 years; reducing greenhouse gas emissions by 20 percent by 2012; and reducing energy use at stores by 30 percent.
You probably already knew this, though.
