Sustainability practices, particularly those relating to Socially Responsible Investment (SRI), have still to be fully evolved in a developing country context. This article considers international trends in SRI and how these may relate to South Africa. It considers how, internationally, SRI has become increasingly motivated by the business case for risk-management and therefore how it may have the potential to offer superior returns (as demonstrated by recent experience in the United States). It examines the relevance of SRI trends to South Africa, where the concept of SRI still faces further structural development, and reviews the performance of funds operating in the South African SRI arena.
