This project maps the materiality of the ISO 26000 Social Responsibility to small and medium-sized enterprises (SMEs) through a global survey of 59 SMEs, 37 social responsibility consultations and 16 National Cleaner Production Centres across the world. It was [carried out by the International Institute for sustainable development] to further investigate the underlying reasons why SMEs continue to be missing from the sustainable development agenda, and if and how the ISO 26000 could serve as a catalyst for their greater participation.
