Technologies that promote pollution control and prevention, recycling, and energy efficiency have already been developed by many industries and companies. These technologies and practices were products of the research and development efforts by industries. There are benefits to be derived from sharing of these technologies. However, some of these technologies are considered to contribute to the competitive advantage of companies. The Eco-Patent Common was conceived to encourage firms, industries, and companies to share technologies that are not crucial determinants of competitive advantage. Technologies that can be shared range from energy efficiency to recycling.
