  1. Scope of Reporting
Total Greenhouse Gas (GHG)Emissions[5] 3,598,169.2 Tonnes of CO2 -e


  1. GHG Reduction Measures[6] Implemented in the Reporting Period
Energy saving
  • Minimised lighting and cooling at offices and venues by taking advantage of natural light, shortening pre-cooling hours, separating the lighting and air-conditioning controls in different zones and areas, and installing occupancy sensors.
  • Installed photovoltaic lighting systems at some museums to convert solar energy into electricity, and controlled the lighting at some parks and playgrounds by using astronomical time switches that switch it on and off according to sunset and sunrise times.
  • Conducted energy audits and energy-saving improvement works where practicable in collaboration with the Electrical and Mechanical Services Department and the Architectural Services Department.
  • Gradually replaced conventional departmental vehicles with environmentally-friendly vehicles.
Paper saving
  • Promoted “reduce and reuse” for saving paper and about 75% of the paper consumed was recycled paper.
  • Issued overdue and reservation notices to library users through emails, and publicised programmes and collected feedback from cultural venue users electronically.
Water saving
  • Stepped up site inspections of irrigation systems to prevent water leakage, used spray nozzles for irrigation to reduce water loss from the soil surface and planted drought-tolerant species in suitable locations.
  • Used less water for water features in major parks, installed water efficient fittings and salt water flushing at various facilities.
Recycling activities
  • Adopted environmentally-friendly materials, used recyclable and reusable office stationery, and placed waste separation bins at over 530 venues.
  • Re-used the yard wastes generated from horticultural maintenance works as soil conditioner for planting.
Staff engagement
  • Regularly circulated circulars and good practices in paper saving, energy saving, waste avoidance and reduction, and improving air quality to staff.
  • Regularly reminded colleagues to choose energy efficient products in line with the mandatory Energy Efficiency Labelling Scheme under the Energy Efficiency (Labelling of Products) Ordinance and for procurement of the prescribed products (i.e. room air-conditioners, refrigerating appliances and compact fluorescent lamps), only those which bear “U1 energy labels” should be chosen.
Housekeeping measures
  • Generally maintained the Government's recommended office room temperature of 25.5°C.
  • Conducted annual performance review to monitor the adoption of green measures and waste reduction practices by sections/offices.


  • Took part in the Earth Hour 2018 lights-off campaign organised by the World Wide Fund for Nature in March 2018 with a view to supporting and promoting energy conservation.
  • Signed the Food Wise Charter under the Food Wise Hong Kong Campaign and encouraged those catering service contractors operating in our leisure/cultural venues to reduce food waste.


  1. On-grid Renewable Energy (RE) System Installed in the Major Buildings[7]
Type(s) of System
(e.g. Solar PV, Wind Turbine)
Annual Electricity Generated by RE System Nil kWh
Reduction in GHG Emissions[8],[9] Nil Tonnes of CO2 –e


[1] “Major Buildings” refer to buildings with annual electricity consumption over 500 000 kilowatt hour (kWh).

[2] According to Environment Bureau Circular Memorandum No. 1/2017, the Department is requested to report and disclose to the public the carbon audit findings of major government buildings with annual electricity consumption of more than 500 000 kWh under their management.  The Department is also encouraged to report the carbon audit results of other government buildings with annual electricity consumption less than 500 000 kWh.

[3] “Total Floor Area” refers to the sum of floor areas of “Major Buildings”.

[4] “Total No. of Employees” refers to those working in the “Major Buildings”.

[5] “Total GHG Emissions” refer to the sum of Scopes 1, 2 and 3 GHG emissions.

[6] The categories of GHG reduction measures suggested here (e.g. energy saving, paper saving etc.) are for B&Ds’ reference.

[7] B&Ds should complete this section if applicable.

[8] Reduction in GHG emissions (Tonnes CO2-e) = Annual electricity generated by RE system (kWh) x Territory-wide default value of emission factor for purchased electricity (i.e. 0.7 kg/kWh) ÷ 1000

For simplicity and consistency, a territory-wide default value of emission factor for purchased electricity is suggested to be adopted to assess the reduction in GHG emissions by RE technologies regardless of the locations of the infrastructure.  The most updated territory-wide default value is available at

[9] B&Ds should note that the reduction in GHG emissions resulting from the installation of on-grid RE systems will NOT be counted towards the overall carbon performance of the government buildings, as the electricity generated by the systems will be fed into the grids of the power companies and transferred out of the buildings at the same time.
