“Sustainability is now mission critical for businesses” World Economic Forum, 2018

“90% of executives now see sustainability as important" (MIT). Their challenge - how to integrate sustainability, without compromising commercial goals and targets. This dilemma is especially acute in the fashion sector, one of the world’s most polluting industries. Thousands of professionals want to operate differently - but don’t know-how.
