How the Index WorksFor example, Walmart's computer buyer used the Sustainability Index and The Sustainability Consortium's (TSC) research tools to identify opportunities to reduce greenhouse gas emissions and save energy from laptops. Only 30 percent of laptops sold at Walmart were using "advanced power management" – a feature that switches the computer to a lower power state when it's idle or used at a reduced energy capacity. The industry had a standard for activating "sleep" mode when a computer's system is in 30 minutes of inactivity. Walmart's computer buyer asked suppliers, when possible, to shorten the time to 10 minutes of inactivity. Walmart now has a goal for 100 percent of the computers it sells this holiday season to have advanced power management as the default setting. This change will eliminate more than 200,000 tons of greenhouse gas emissions and save customers money on electricity bills.Learn more about Walmart's commitment to sustainability at The Green Room or on our website and follow us on Twitter ( @WalmartGreen) to get updates about sustainability efforts and milestones.
