We work closely with our finished goods, and materials suppliers to support their water resiliency through flood and drought risk identification and preparation, water efficiency management, wastewater quality management, and water security.
To help suppliers identify risks related to floods and drought, we use the World Resources Institute’s (WRI) aqueduct tool to conduct water risk assessments for all sites across finished goods and materials manufacturing facilities. The tool provides a general picture of global risks, but understanding water risks at the local level is critical. Since 2020, we've been conducting site-level water risk assessments, validating the water risk for 20% of sites located in extremely high-risk regions and working with suppliers to implement strategies to mitigate disruption to their operations.
Our program to optimize facility water use, includes work to reduce the water used to dye and finish textiles, which makes up 18% of our overall freshwater footprint. Over the last decade, we have focused on increasing water efficiency, recycling, and implementing advanced water treatment technologies, reducing water usage by more than 50% across our strategic material manufacturing suppliers, representing approximately 80% of materials production.
We partner with suppliers to train and enable them to develop capabilities that not only manage water use responsibly and securely, but to also treat wastewater responsibly. Tier 1 finished good and Tier 2 materials suppliers are part of in NIKE's Water Minimum Program, which outlines the expectations for suppliers to adopt the most rigorous water management practices within the industry.
Nike is also a member of ZDHC, Zero Discharge of Hazardous Materials – a voluntary industry program that sets standards above regulatory requirements for chemical use and wastewater management. In FY23, 100% of our suppliers participated in the ZDHC wastewater sampling program and over 95% of facilities achieved compliance.
Recognizing the reported risks of microfibers and microparticles on the environment, NIKE is leading the development of ZDHC guidelines and research to control and measure microfibers and microparticles, expanding ZDHC’s guideline scope beyond chemical wastewater management.
