Portfolio 21 is a unique investment management firm based in Portland, Oregon. I recently wrote a book chapter reviewing their business practices for the upcoming book "Investing in a Changing World", to be published by Wiley in late 2011. It is such a fascinating approach to investing that wanted to share some excerpts from my interview with Portfolio 21 Director and Co-Founder, Carsten Henningsen.
What sets Portfolio 21 apart from many investment managers that I’ve come across is that they apply the principles of The Natural Step and The Global Footprint Network to their investment process. As a result, Portfolio 21 does not invest in any mining, oil or gas stocks. Not one. And it still performed relatively well compared to its benchmarks.
