The institute is an international, multi-stakeholder, not-for-profit initiative supporting the UN and the implementation of the Sustainable Development Goals. UNGSII aims to provide an evaluation and comparison of companies’ and countries' sustainability performance in a transparent manner. UNGSII's unique SDG-focused research and data approach provides guidance and benchmarking to companies and stakeholders, including investors, to encourage progress, but also to apply pressure to improve sustainability performance.  Existing assessment and measurement approaches are used as a starting point to ensure that best practice is fully integrated. Bottom line success will be the driving force of the UNGSII. The criteria for the index will favour those companies who are working not only to limit the environmental and social footprint of their activities but to achieve a net positive impact, in other words, those companies aiming at win-win rather win-lose relationships with their customers, employees and other stakeholders.
