Are you a practitioner or teacher of sustainable development, either as a consultant or an employee? Then you know that we need to restore the damage done to our life-support systems and social fabric while charting a course to new and attractive futures. Legacy17 contributes process knowledge and skills: curating the best ways and methods to achieve high impact for Agenda 2030 and beyond. We are international, cross-cultural, transdisciplinary, with decades of experience. We focus on professional development, leadership, and social marketing. Our common base is action learning and action research. By cooperating with universities we make outstanding methods, tools, and people-skills more readily available. It also opens opportunities for research to further improve them. Follow us on social media: https://www.facebook.com/legacy17org https://twitter.com/legacy17org?lang=en
