Levi Strauss & Co.

The 140-year-old blue-jean and khaki giant is rolling in the green. Levi's Waste < Less program, launched last spring, uses 20% recycled materials—about eight 12- to 20-ounce plastic bottles—in each garment. In the fall, Levi's Dockers brand debuted Wellthread, designed to recycle old mater­ial into new clothing and make sustainable apparel cheaper to produce.
