Nike says it is incorporating the environment into its decision-making, and even Greenpeace cautiously agrees that the company seems to be moving in the right direction. Nike says that by 2001, nine of 10 shoes it manufactures will be made without toxic glues, cleaners, or solvents. The company has also pledged to find an alternative to sulfur hexafluoride, a greenhouse gas that it uses in air cushions for its shoes. In 1998, Greenpeace praised Nike’s move to phase out polyvinyl chlorides in its products. Ultimately, the company says it wants to sell products that are made from recycled materials and are themselves recyclable. All of its cotton T-shirts are now 3 percent organic.
