The Sustainable Apparel Coalition (SAC) is a trade organization comprising brands, retailers, manufacturers, government, and non-governmental organizations and academic experts, representing more than a third of the global apparel and footwear market. The Coalition is working to reduce the environmental and social impacts of apparel and footwear products around the world.

In 2017, the Sustainable Apparel Coalition and its partners (Target, PVH Corp, Gap Inc and HSBC Holdings) formed the Apparel Impact Institute which is designed to work with brands and manufacturers to select, fund, and scale projects that dramatically improve sustainability performance of the apparel and footwear industry. Clean by Design is the first program supported by the institute.
