3. GHG Reduction Measures5 Implemented in the Reporting Period
Energy saving
  • Conducting routine checks to ensure that lights/ air-conditioning are switched off outside office hours
  • Modifying group lighting switches to individual switches
  • Reminding staff of switching off computers, air-conditioners, lights and other electrical equipment and appliances before leaving office
  • Reminding staff of maintaining the air-conditioning temperature in office at 25.5 °C
  • Reducing the time and frequency of using Floodlights and Spotlights in CAS Headquarters
  • Changing part of the lighting facilities in CAS Headquarters to LED lights.
Vehicles
  • Controlling fuel consumption
Paper saving
  • Using blank side of used papers for drafting or printing
  • Using the recycled paper
  • Photocopying limited to the absolute minimum and on both sides of papers
  • Increasing use of email and Local Area Network (LAN) in external and internal communications
  • Circulating documents in soft copies instead of providing personal hard copies
  • Printing reports/publications limited to the absolute minimum and uploading publications on the CAS Internet
  • Encouraging paperless meetings to reduce the printing of agenda, minutes of meeting and reference materials
Water saving
  • Carrying out regular checking on pipes, tanks, tap washers and other water supply systems to prevent leakage and to make repairs if needed
Recycling activities
  • Placing Waste Separation Bins at CAS Headquarters
Staff engagement
  • Encouraging staff to use staircase for inter-floor traffic
  • Encouraging staff to bring their own water cups instead of disposable paper cups
Housekeeping measures
  • Re-circulating departmental circulars on ‘Green Housekeeping’ at regular intervals
  • Displaying an advisory note on paper-saving in all Lotus Notes e-mail messages
  • Setting up an environmental corner on CAS e-Garden to announce environmental issues and measures
Others
  • Selecting computers and electrical appliances with Energy Efficiency labels
  • Adopting ‘green procurement’ concept as far as practicable
  • Using green stationery items supplied by the Government Logistic Department
  • Including ‘trade-in option’ in quotations when procuring fax machines and photocopiers


4. On-grid Renewable Energy (RE) System Installed in the Major Buildings6
Type(s) of System
(e.g. Solar PV, Wind Turbine)		 N/A
Annual Electricity Generated by RE System N/A kWh
Reduction in GHG Emissions7,8 N/A Tonnes of CO22-e


1“Major Buildings” refer to buildings with annual electricity consumption over 500 000 kilowatt hour (kWh).
2“Total Floor Area” refers to the sum of floor areas of “Major Buildings”.
3“Total No. of Employees” refer to those working in the “Major Buildings”.
4“Total GHG Emissions” refer to the sum of Scopes 1, 2 and 3 GHG emissions.
5The categories of GHG reduction measures suggested here (e.g. energy saving, paper saving etc.) are for B&Ds’ reference.
6B&Ds should complete this section if applicable.
7Reduction 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 https://www.climateready.gov.hk/education_centre.php?section=guideline_reference_links.
8B&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.
