The city of Denver has achieved registration to ISO 14001, the international standard for environmental management systems, from the International Organization of Standardization in Geneva. The Office of the Mayor, Department of General Services (which includes theaters and arenas for the Colorado Convention Center), Department of Public Works, Department of Environmental Health, and the Denver Zoo have achieved the registration. “This certification is a great honor for the city and carries with it an ongoing responsibility to do our part to make and keep Denver a sustainable community,” says Denver mayor John W. Hickenlooper. “We are up to the task; managing to the ISO 14001 standards is consistent with the goals of our Greenprint Denver initiative and will help us protect our environment, improve our operations, and save money.” Greenprint Denver is an initiative of the mayor’s office to promote the importance of sustainable development and ecologically friendly practices. ISO 14001 is designed to continually improve environmental performance. It provides guidance about how to manage the environmental aspects of an organization’s activities, products, and services more efficiently while taking into consideration environmental protection, pollution prevention, and socioeconomic needs. To earn registration, Denver had to complete several registration steps, which involved audits and reviews. By achieving the certification, Denver was able to increase efficiency and use of energy and raw materials, manage environmental risks, and create a platform from which other environmental health and safety initiatives can be developed.
