Voluntary Energy Efficiency Labelling Scheme
To make it easier for the public to choose energy efficient products, EMSD operates a voluntary Energy Efficiency Labelling Scheme for appliances and equipment used both at home and office as well as for vehicles. The scheme aims to save energy by informing potential customers of the product's level of energy consumption and efficiency rating, so that buyers can take these factors into consideration when making their purchasing decision.

The scheme now covers twentytwo types of household appliances and office equipment. Thirteen types of which are electrical appliances including refrigerating appliances (Voluntary Scheme), washing machines (Voluntary Scheme), non-integrated type compact fluorescent lamps, dehumidifiers (Voluntary Scheme), electric clothes dryers, room air conditioners (Voluntary Scheme), electric storage water heaters, television sets, electric rice-cookers, electronic ballasts, LED lamps, induction cookers and microwave ovens. The seven types of office equipment include photocopiers, fax machines, multifunction devices, printers, LCD monitors, computers and hot / cold bottled water dispensers. There are two types of gas appliance for domestic gas instantaneous water heaters and gas cookers. The scheme has also been extended to cover petrol passenger cars.
EMSD has extended the voluntary Energy Efficiency Labelling Scheme (EELS) to cover microwave oven with effective from 18 December 2014.
To further facilitate the public in choosing energy efficient appliances and raise public awareness on energy saving, the Government has introduced a Mandatory Energy Efficiency Labelling Scheme (MEELS) through the Energy Efficiency (Labelling of Products) Ordinance, Cap. 598.
The MEELS covers five types of products, namely room air conditioners, refrigerating appliances, compact fluorescent lamps, washing machines and dehumidifiers. The Voluntary Energy Efficiency Labelling Scheme for room coolers, household refrigeration appliances, washing machines and dehumidifiers shall cover only the type of products not regulated under the Ordinance.
