The goal of the ZDHC wastewater requirements within the supplier Roadmap to Zero 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 the guidance and, therefore, accomplish this goal.

For suppliers an aligned set of metrics eliminates the need to meet overlapping individual brand requirements, thereby reducing the need to carry out multiple, different tests.

For brands, it allows the use of information from already completed testing and the ability to track supplier progress of continuous improvement.
