In recognition of the need to improve energy efficiency in Hong Kong, the Government has introduced a voluntary energy efficiency labelling scheme. Here you can learn more about the scheme, the types of appliances and equipment it covers, and where you can check if a product is registered.
The Electrical and Mechanical Services Department runs a voluntary Energy Efficiency Labelling Scheme for appliances and equipment used in the home and office, and for petrol-powered vehicles. Manufacturers, importers and the like can join the scheme to promote their environmentally responsible products. The labels that are issued provide information on energy consumption and efficiency to help you make better purchasing decisions.
The grading-type energy label tells you how much energy an appliance is likely to consume in a year of average use. It also grades that energy efficiency on a scale of one to five, with one being the most efficient and five the least efficient. More generally, grading-type energy labels apply to:
A registration number is issued to each classified brand, so you can rest assured that it has met the Government's exacting standards.

The recognition-type energy label does not grade an appliance's energy efficiency. Rather, it tells you that the product has been certified to meet the minimum energy efficiency and performance requirements. The following products are issued with the recognition-type energy label:
Products that carry the recognition-type energy label are registered by the Electrical and Mechanical Services Department.

In 2002, the Electrical and Mechanical Services Department extended the voluntary energy efficiency labelling scheme to petrol passenger cars. The fuel consumption of a car usually depends on the way it is driven, so the label contains information on:
All three types of fuel consumption are measured in litres per kilometre, with a lower number indicating greater efficiency. The label is displayed on new cars that are registered under the scheme, so you can compare the fuel efficiency of models before buying.
To ensure that you can always check whether your appliances and equipment have been registered, the Electrical and Mechanical Services Department maintains registers of the following items.
All four registers are available online at the Department's website.
