The fourth phase of the Mandatory Energy Efficiency Labelling Scheme will be fully implemented on December 1 to include light emitting diode (LED) lamps, gas cookers and gas instantaneous water heaters.

Taking the fourth phase into account, the scheme covers a total of 11 types of products, including room air conditioners, refrigerating appliances, compact fluorescent lamps, washing machines, dehumidifiers, televisions, storage type electric water heaters, induction cookers, LED lamps, gas cookers and gas instantaneous water heaters.

The scheme's fourth phase came into effect on September 1, 2023, with a transitional period of 15 months.

The implementation of the fourth phase will save annual energy of around 160 million kilowatt-hours, equivalent to a reduction of about 75,000 tonnes of carbon emissions. The total energy consumption in the residential sector covered by the scheme will substantially increase from about 50% to about 80%.
