The store already cut carbon dioxide emissions by 10 percent in its North America stores and made use of daylight in its Greenboro, North Carolina store, which saves about 250,000 pounds of greenhouse gases each year.

Now it plans to build its first LEED (Leadership in Energy and Environmental Design)-certified store in Austin, Texas.

Not only is it a good move for the environment, but these initiatives have profited the company, too. It claims to have saved more than $6 million in electricity costs due to energy efficiency and conservation efforts in its stores.
