The aim of this cross-sector Retreat is to shed light on several implementation that have shifted their strategies to cater for more environmental, economic and social course. It will offer a guideline and opportunity to answer the following questions: what have we done? How did we do it? What was not done well? How it should have been done it? What should we do and when should it start? The retreat therefore establishes a focal point in shaping sustainability practice in relationship to the United Nations Global Goals (SDGs).
