It's our internally developed environmental classification system that we use to help green the company's chemistry. Created in 2001, the Greenlist™ process helps our scientists select better ingredients and phase out less desirable ones. When SC Johnson scientists create a new product or reformulation, they work to select raw materials with the highest possible ratings. Reformulations must use ingredients that have ratings equal to or better than the original formula. You can learn more about the Greenlist™ process here.
