SAN FRANCISCO – The Sustainable Apparel Coalition (SAC) has launched the Higg Index Design and Development Module (DDM) which helps product designers and developers to make sustainable choices at the earliest stage of apparel, footwear and textile prototype design. The data collected through the Higg DDM, which replaces Higg's Beta Rapid Design Module, is aimed at helping steer designers towards selecting lower impact materials, using more efficient construction techniques, and considering the complete life cycle of the product.
