Patagonia (the clothing company) campaign shows the impacts of its supply chain
"The Footprint Chronicles® examines Patagonia’s life and habits as a company. The goal is to use transparency about our supply chain to help us reduce our adverse social and environmental impacts – and on an industrial scale. We’ve been in business long enough to know that when we can reduce or eliminate a harm, other businesses will be eager to follow suit"
