Achievements of appliance energy efficiency standards and labelling programs: A global assessment

National energy efficiency standards and labelling (EESL) programs have been in existence since the 1970s and now operate in more than 80 countries around the world, covering more than 50 different types of appliances and equipment in the commercial, industrial and residential sectors. While the design and coverage of EESL programs vary according to national circumstances, they provide the cornerstone of most national energy efficiency and climate change mitigation programs.
