Greentrade presents businesses attempting to practice sustainability. These are people who are sincerely asking the question, "How can our business improve the quality of life?" For evaluation tools for determining whether a business is truly practicing sustainability, explore The CERES principles and the Sustainable Business Network as starting points. And of course, you can ask the Greentraders themselves.
