S. C. Johnson & Son's Greenlist process is a classification system that evaluates the effects of raw materials on human health and the environment. The Greenlist logo represents an internal ratings system to help customers identify which products are environmentally safe. The Greenlist label is present in many S. C. Johnson & Son products. The Greenlist process has resulted in the elimination of 1.8 million pounds of volatile organic compounds from Windex, and four million pounds of polyvinylidene chloride from Saran Wrap.
