Canada
Canada's EnerGuide comparative labeling program, initiated in 1978, is the oldest energy labeling program in the world. Labels are mandatory for major household appliances and room air conditioners and voluntary for other equipment including furnaces, central air conditioners, and gas fireplaces. In 2001, Canada signed an agreement with the U.S. to administer the international ENERGY STAR program in Canada. Since then, Canada has been managing a voluntary ENERGY STAR labeling program to help Canadian consumers select the most energy efficient products in a wide variety of product categories.
