Just last week the PRI Makers Network (PRI stands for Program Related Investments) met in New Orleans. Video footage of the Network meetings is now available on The Giving Channel.*
What signs point to a movement? Several - growth in the PRI Makers Network. A peer-to-peer challenge, called the 2% Challenge to get foundations to invest in ways that advance their social missions. Socially responsible investing is itself the fastest growing segment of managed assets. (source, Social Investment Forum). Growth in clean tech and green tech investment vehicles, many of which are backed by endowment assets. Third party resources on the subject. - OK, I said, it is a small movement now. We'll be watching to see if it grows. You can watch those who are already a part of the action over at the Giving Channel (and suggest resources, join in the Forum discussion, and suggest other topics for similar coverage).
