Sustainable and responsible investment is rapidly becoming increasingly important as an investment market for a wide range of players. As defined in the 2010 European SRI Study by Eurosif, providing an interesting overview of this investment market, there are two constant factors that remain important to investors interested in this form of investment:
1. A concern with long-term investment;
2. Environmental, Social and Governance (ESG) issues as important criteria in determining long-term investment performance.
Other recent studies include those of the SAM Institute, and a research overview can be found in a recent article in the Journal of Business Ethics, specifically focusing on the heterogenity of SRI.
