As social and environmental ventures seek new ways to attract capital while retaining their social objectives, some have floated the idea of creating a social stock market.  This would be an exchange platform similar to the NYSE, but the companies listed would be valued based on both financial and social performance.  To date, there have been some attempts at this.  One example is Ethex, the ethical exchange or matched trading service provided by Triodos Bank in the UK.  A fully functioning social stock market would require the engagement of many entities from rating agencies to brokers who understand how companies are operating to “maximize shareholder value” from a new perspective. 

Not everyone thinks this is a good idea.  There is an interesting debate going on over in the Catalyst Fund’s Blog:  http://www.catfund.com/blog/ you may wish to check out if you are interested in their opinion.
