Knowledge base

The goal of the wastewater guidance is to eliminate the discharge of hazardous chemicals in the textile, apparel, leather and footwear industries. Having one, single expectation makes it easier for suppliers to implement guidance and therefore accomplish this goal. An aligned set of metrics eliminates the need to meet overlapping individual brand requirements, thereby reducing the need to carry out multiple, different tests. Following the three-level Foundational, Progressive, Aspirational limits approach, suppliers will also be able to demonstrate their continuous improvements over time.
