Patagonia comes to mind as a pioneer in this area, as a market leader setting sustainability standards.
Fjällräven ( the name means artic fox) is a Swedish company, specialising in outdoor equipment. In 2013 they launched The Fjällräven Way, a document that acts as a guide for their sustainability work. It contains four areas of activity linked to the cardinal points of the compass - the universal tool for way-finding.
N stands for Nature & Environment
E for Economy & Business Processes
S for Social Responsibility
W for Wellbeing.
"Our goal is a healthier outdoor life, now and for future generations." Aiko Bode, Fjällräven's Chief Sustainability Officer, explains how they work with sustainability throughout the entire company.
