SustainableBusiness.com recently announced its 2009 Sustainable Business 20 (SB20) List: The World’s Top Sustainable Stocks. The 8th Annual SB20 List consists of 20 public companies that are leading the way to a sustainable economy. The list is presented in the Progressive Investor newsletter, published by SustainableBusiness.com, which tracks and analyzes green stocks. To choose the 20 companies, SustainableBusiness.com works with a group of judges, who are among the most respected green stock analysts in the world. Judges select companies across the range of green business sectors – solar, wind, geothermal, smart grid, water, food, agriculture, green building and transport. In addition, over a third of the companies populating this year’s SB20 List are “Corporate Pioneers” – companies with conventional products and services that are greening their product lines.
