The 2015 Sustainia100 study features 100 new stories from the forefront of sustainability innovation. Deployed in 151 countries, the solutions feature new ways of saving water, managing waste, building homes and safeguarding our food production. The top-100 sustainability solutions were found after reviewing +1500 projects and businesses on six continents. This year’s 100 innovations point to a paradigm shift in eco-innovation: more than half of this year’s selected innovations are not only competing on sustainability criteria, but also on affordability and convenience with for instance new reuse, recycling and take-back models.
