The Natural Step and Sustainability explained in 2 minutes. Finally someone has figured out how to explain The Natural Step and sustainability in two minutes!! We're so excited to share with you this fantastic animation video on core concepts of the Framework for Strategic Sustainable Development, including the four sustainability principles. It was written by our brilliant friends at RealEyes in Dublin, who help organizations benefit from sustainability. And it was developed by our new friend Trevor Courtney at Igloo Animations. Trevors animation work is fantastic. We hope you will enjoy this video, like it and share it widely to help spread sustainability and the framework.
