In the United States and in Canada, the International Organization for Standardization has issued guidelines for properly identifying environmental claims. As the popularity of the green movement has spread, so have claims by manufacturers attempting to connect with the movement. Unfortunately, many of these products do not live up to their billing. ISO 14024 identifies products that have undergone stringent testing procedures to validate their green and sustainable claims. Products complying with ISO 14024 are tested once a year and the manufacturing facilities undergo random on-site testing to assure green integrity.
