What are the 100 solutions that can bring about a sustainable society? Scandinavian think tank Sustainia has launched its third annual global campaign to find the answers. With a worldwide alliance of companies and organizations, the goal is to identify the world’s 100 leading sustainability projects and technologies across sectors such as food, fashion, energy, smart homes etc. Collectively, the solutions will form the 2014 Sustainia100, a comprehensive guide to state-of-the-art sustainability practices in various industries and regions.
