This LEED Platinum home exhibits a large variety of sustainable features, including this notable cork flooring. Cork has excellent properties for such an application, in addition to giving a soft, warm color to the house interior (though other cork flooring can come in many patterns and colors as well).

It is also a highly renewable material, and exhibits a long list of other excellent aspects, as detailed in the last half of this page (click thumbnail below):
