"Do Socially Responsible Investment (SRI) guidelines promote corporate environmental performance?" This is the title of a study commissioned by the Consumer Concil which was finalized end of October 2012. The study looked at the environmental criteria used by the following institutions: Dow Jones Sustainability Index (DJSI) - Ethibel Ecolabel Index - FTSE4Good Index series - Environmental and Social principles of the IFC, World Bank - The Equator Principles - European investment Banks (EIB) environmental and social principles and standards - PRI principles. The conclusions are disillusioning. Ambitious performance requirements, comparable quantitative indicators and benchmarks are widely missing, applied methodologies lack transparency with respect to the criteria themselves or their practical implementation. Overall it can be doubted that significant environmental performance improvements are achieved.
