Chapter 3 - Environmental Management and Performance

(A) Providing Aesthetically Pleasing Open Space and Promoting Greening and Horticulture

3.1 In providing aesthetically pleasing open space and promoting greening and horticulture, we have five areas of work. They are –
  • Provision of open spaces that are aesthetically pleasing;
  • beautification of existing landscape areas;
  • planting programme;
  • education and promotion on environmental protection; and
  • greening activities.
3.2 (I) Provision of Open Spaces that are Aesthetically Pleasing
  • In 2018, 14 open space projects (including capital works projects and minor works projects) were completed, resulting in an increase of about 4.197 hectares of open space in Hong Kong.  A list of these projects is shown at Annex I.
  • In general, 70% of the passive recreation areas will be used as landscape area.  Conspicuous flowering and shade trees, colour foliage and flowering shrubs of hardy species will be chosen to create colour contrast and seasonal changes.  We aim to achieve sustainable landscape through selection of more low maintenance and native plant species.
  • When planning new open space projects, the facility will be designed and constructed with consideration to environmental performance, such as application of energy-saving building services installations and use of environmental-friendly materials such as products with high recycled content.  Appropriate materials should be used to create an user-friendly, comfortable environment and to achieve low recurrent maintenance cost.
  • Apart from new open space projects, there are on-going improvement and upgrading works to existing parks and playgrounds.
3.3 (II) Beautification of Existing Landscape Areas
  • In 2018, about 17 hectares of existing landscaped areas (including roadside amenity areas) were upgraded through the effort of district staff in carrying out landscape improvement works.  We would continue to enhance the landscaping of parks and roadside amenity areas in order to provide a pleasant environment to the public.Beautification of Existing Landscape Areas Photo

(III) Planting Programme

Around 2.14 million trees, shrubs and annuals were planted in 2018 (breakdown at Annex II).  We continued the planting of flowering species to enhance the visual impact with more seasonal colours.

3.5 (IV) Education and Promotion on Environmental Protection

(a) Horticulture Courses for the General Public

During 2018, the Department conducted 50 horticulture courses for 1 500 participants.

(b) Guided Visits for Schools and Non-governmental Organisations (NGOs)

The Department organised 878 guided visits for 30 508 participants from schools and NGOs.  They included 661 school guided visits for 23 180 school children at the Hong Kong Zoological & Botanical Gardens, Green Education Resource Centre, Kowloon Park, Hong Kong Park, Tai Po Waterfront Park, Tuen Mun Park and Boundary Street Nursery.  The guided visit was designed having regard to the curriculum on environmental education for primary schools.  Besides, 200 visits were arranged for 6 855 children from kindergartens to tour around Kowloon Park and Hong Kong Park.  Children were introduced the basic knowledge and concept of plants, environmental conservation and appropriate manners for visiting parks.  Free guided visits were also arranged for 473 participants from 17 NGOs to tour around the Green Education Resource Centre at Kowloon Park.

(c) Conservation Courses for Uniformed Groups

The programmes provided a wide range of courses in gardening and arboriculture and aimed at promoting nature conservation. A total of 12 conservation courses were organised for 407 participants of the uniformed groups in 2018. Participants were involved in group discussions, lectures, guided visits and practical learning.

(d) Seminar and Gallery on Environmental Protection

  • The Hong Kong Science Museum staged exhibitions and organised lectures to arouse public awareness on environmental issues, including –

staging the “SOPHIE - IVE's Solar Cars Driving the Future” exhibition  from March to September 2018 which introduced the latest technology applied in the conversion of renewable solar energy into electricity through the display of the solar car “SOPHIE IV”, which was developed by a group of teachers and students from the Hong Kong Institute of Vocational Education; and

(ii) presenting public lectures on environmental issues in the series of “Science in the Public Service” from July to December 2018, and “Weather-ready, Climate-smart” in November 2018. Lectures such as "Climate Change Impact on Hong Kong" and "Food Safety in a Smart City in the Face of Climate Change" have been organised to raise the public's awareness on climate change.
  • The Hong Kong Space Museum, in collaboration with the Department of Physics of the University of Hong Kong (HKU), has been conducting the research project “Hong Kong Night Sky Brightness Monitoring Network” on light pollution since September 2010. Funded by the Environment and Conservation Fund initially, the project aims at carrying out a comprehensive monitoring of the condition of light pollution in Hong Kong by studying the night sky brightness at about 18 urban and rural locations, including the Space Museum, iObservatory and Astropark.  The Space Museum has continued to collaborate with HKU via the research project “Globe at Night – Sky Brightness Monitoring Network”, which is the overseas extension of the previous project, since July 2017.  In addition, the Space Museum organised various activities, including public seminars, student competitions and exhibitions to spread the message of light pollution reduction further and wider.
3.6 (V) Greening Activities

The Department continuously promotes a green culture in the community through a series of educational and community involvement programmes.  A total of 3 223 greening activities were organised for the year of 2018, including –

(a) Hong Kong Flower Show
The Hong Kong Flower Show 2018, with the theme “Joy in Bloom” and dahlia as the theme flower, was held from 16 to 25 March 2018 at Victoria Park, attracting a record high of over 720 000 visitors.  The Show aimed at promoting public interest in horticulture and arousing public’s awareness of conservation of natural environment.  A signature horticultural event in the territory, the Show impressed flower lovers with garden plots and displays that featured both Chinese and Western elements, drawing support from more than 200 horticultural organisations, private firms and government departments from 18 countries.    In addition, a wide variety of community engagement and fringe activities were organised before and during the event involving the District Councils, schools, horticultural organisations, plant nurseries and flower clubs.  To step up our green efforts, the Department held the inaugural “Green Recycling Day” upon the conclusion of the Show with an aim to reduce waste and promote a green message.  A selection of landscaped displays found new homes at LCSD parks and amenity areas, while re-plantable flowers were given away to schools, environmental groups and non-governmental organisations and members of the public.

(f) Greening Hong Kong Activities Subsidy Scheme
The Scheme aimed at encouraging the local community to organise more greening activities.  Six organisations were subsidised under this Scheme in 2018 to organise greening activities.
(g) Greening Exhibitions and Talks
Greening exhibitions and talks on horticulture were organised at the Green Education and Resource Centre at Kowloon Park in 2018 with a view to educating and arousing public awareness in greening.  A total of 389 exhibitions and talks were organised with about 28 000 participants.
(h) Community Garden Programme
To encourage the public to participate actively in greening activities at the neighbourhood level and to adopt greening activities as part of daily life, 55 gardening courses were organised in 2018 with about 11 300 participants.
(i) Outreaching Greening Promotional Activities
To promote greening and enhance public awareness in greening and environmental protection, 181 outreaching greening activities were delivered to organisations and schools for about 55 100 participants in 2018.

(B) Preserving Assets of Our Heritage

3.7 The Department, through the Antiquities and Monuments Office (AMO), is committed to preserving Hong Kong’s cultural heritage.  Under the Antiquities and Monuments Ordinance, the Antiquities Advisory Board (AAB) advises the Secretary for Development, i.e. the Antiquities Authority, on matters relating to antiquities and monuments.  The AMO works closely with AAB and acts as the Authority’s executive arm under the Ordinance.
3.8 In addition, the AMO plays an important role in monitoring Environmental Impact Assessment for Designated Projects under Environmental Impact Assessment Ordinance (Cap. 499) insofar as their impacts on antiquities and monuments is concerned.  The work involves inspecting sites of cultural heritage, examining mitigation measures to avoid any possible damage to the sites and conducting, where necessary, rescue excavations at archaeological sites and cartographic recording of historic buildings.
3.9 The AMO also organises educational programmes to promote heritage preservation among the public.

The Department firmly believes that cultural heritage not only enhances our built environment and the natural landscape, but also provides an essential and irreplaceable link between the past, the present and the future.  It forms the basic points of reference for our cultural identity and traditions.

Preserving Assets of Our Heritage Photo

3.11 Up to end 2018, there were 120 declared monuments, including 102 historic buildings and structures as well as 18 rock carvings, forts, stone inscription and archaeological sites.
3.12 The AMO carried out restoration and repair works on a number of monuments and historic buildings, mainly including St. John’s Cathedral in Central, Maryknoll Convent School in Kowloon Tong and I Shing Temple in Yuen Long.
3.13 Archaeological surveys and excavations necessitated by small-scale development projects such as small house development in the New Territories were conducted by the AMO in Sai Kung, Lamma Island, and Lantau Island.  The archaeological surveys and excavations have successfully salvaged the archaeological heritage, if any, found at the sites.

On education and publicity, the AMO organised a wide variety of educational and publicity programmes, such as exhibitions, displays, lectures, guided tours and workshops, to promote heritage conservation.  A long-term exhibition on the archaeological and built heritage has been staged in the Hong Kong Heritage Discovery Centre.  In total, the office conducted 1 459 heritage educational programmes and produced 14 publications in 2018.

(C) Practising Waste Reduction and Energy Saving

3.15 We proactively explore ways to promote paper saving, energy saving and waste reduction, including conducting energy audits to identify good energy management practices.  Measures/ housekeeping practices adopted are shown in the ensuing paragraphs.

(I) Paper Saving

3.16 The Department continued to adopt good practices on paper saving using “reduce and reuse” strategy, particularly in replacing paper-based correspondences with electronic means.  In 2018, we also made the following endeavours –

we provided an electronic newspaper clipping service to the Department’s Lotus Notes users to ensure that the number of hard copies is kept at a minimum;
we produced e-versions of the departmental yearbook and departmental Christmas cards only;
Library users were given the option to receive some library notices through e-mail or library mobile app on smart phones, and thus economised on the use of paper.  As at 31 December 2018, over 461 000 registered borrowers have opted for the email notification, while over 393 000 times of download of library mobile app have been recorded.  In addition, 483 382 kg of unserviceable library materials were recycled in 2018. 
museums and Hong Kong Film Archive, Hong Kong Visual Arts Centre and Oil Street Art Space also reduced waste by recycling exhibition materials and placed collection boxes for collecting used guide maps/pamphlets disposed of by patrons after their visits for recycling purpose;
performing arts venues and programming offices used electronic means to publicise performing arts programmes and collect feedback.  Admission letters to schools rather than individual URBTIX tickets were issued for student group admission of performances.  Printing of flyers and house programmes was reduced by tightly monitoring distribution and minimizing the pages printed.  In addition, unused copies of flyers and house programmes were recycled and electronic version of house programmes were further adopted as far as possible;

most of the performing arts venues also installed digital screen / electronic monitors to replace conventional foam boards or paper posters for programme promotion; and

Practising Waste Reduction and Energy Saving Photo

in line with the Government’s initiative of paper saving, the tenders and quotations issued by the Headquarters Supplies Section were made in electronic format (i.e. by means of CD-rom) and suppliers were encouraged to adopt environmental-friendly measures in the preparation of tender/quotation documents (such as using recycled paper) and to minimise the use of packaging materials.  Besides, about 77% of the paper we consumed in 2018 was recycled paper.

(II) Energy Saving

3.17 The Government has set a new target of 5% saving in the electricity consumption of government buildings under comparable operating conditions from the financial year (FY) of 2015-16 to 2019-20, using the electricity consumption in FY 2013-14 as the baseline. 
3.18 To achieve the target of 5% saving, we have continued our effort to manage our resources responsibly. Energy-saving building services installations and environmental-friendly materials were used whenever applicable.
3.19 The electricity consumption of government buildings under LCSD in FY 2018-19 was 316.9 million kWh.  The table below shows the electricity consumption of LCSD buildings in the past five years from FY 2014-15 to FY 2018-19.

Electricity consumption of LCSD buildings Table

(a) Change in Electricity Consumption

3.20 The electricity consumption of government buildings under LCSD continued to decrease from 319.5 million kWh to 316.9 million kWh in FY2018-19 as compared to FY2017-18 under comparable operating conditions.  The decrease was mainly due to sections/venues’ implementation of practicable housekeeping measures and best practices for energy savings, including switching off unnecessary lights, air-conditioning installation, equipment and appliances, replacement of equipment by energy efficiency models, etc.  The details of housekeeping measures for energy saving were provided in paragraphs 3.22 to 3.24 below. 
3.21 The change in electricity consumption has factored in significant changes in opening/closure of venues/facilities, addition/reduction of services, addition/removal of plants/equipment, extended/shortened service hours, increased/decreased demand for services, change of chairmanship of Building Management Committee1, etc. for a like-to-like comparison.
1 The electricity consumption of a Municipal Services Building is counted towards the department holding the Building Management Committee chairmanship.

(b) Housekeeping Measures for Energy Saving

3.22 The following housekeeping measures for energy saving were commonly adopted in the Department’s offices and venues (including leisure venues, performing arts venues, libraries and museums) in 2018 –
maintaining the 25.5°C office room temperature target set by the Government for the summer months in general.  At places such as museums, libraries, sports centres and performing arts venues where we could not strictly maintain this temperature due to essential operational and/or customer service considerations, we worked closely with the Electrical and Mechanical Services Department (EMSD) to keep the temperature as close to 25.5°C as practicable;
appealing for staff’s support in adopting a more relaxed code of business attire and dress down in the summer for energy conservation and improving air quality in Hong Kong;
using high-efficiency lighting systems (fluorescent tubes with electronic ballasts, motion/occupancy sensors and optical fibres) and energy efficient lamps such as T5 and LED lighting to achieve energy saving as far as possible;  
rationalizing the number of fluorescent lamps and operating hours of offices/venues lightings as appropriate to reduce electricity consumption;
switching off the lights for facilities without booking or left idle;
suspending external lightings used for decorative, promotional or advertising purposes from 11pm to 7am daily except for those decorative lightings that are required to cater for some special festive occasions such as Christmas, New Year and Lunar New Year;
shortening pre-cooling hours as deemed appropriate;
separating the lighting/air-conditioning controls in different areas/zones of venues so that the lighting/air-conditioning system could be tuned or switched on as necessary to save energy;
save for operational needs and safety/security reasons, switching off external lighting installation of some venues all year round;
shortening the operation hours of water features where applicable;
maximising the use of natural light and turning off the lights in the venues where illumination level was acceptable; and
installing speed control/passenger sensors for escalators or reducing their operation time as deemed appropriate.
3.23 Apart from the above commonly adopted housekeeping measures, some venues also implemented other practicable measures that could address their operational characteristics or specific environment for energy saving –

using photovoltaic lighting systems in Hong Kong Science Museum, Hong Kong Museum of Art, Ko Shan Theatre New Wing, Yau Ma Tei Theatre, Tiu Keng Leng Public Library, Kwai Tsing Theatre, Tsuen Wan Town Hall and Tuen Mun Town Hall to promote the energy saving concept by converting solar energy directly into electricity;
installing solar energy lights in Kowloon Park, Jordan Valley Park, Morse Park, Kai Tak Runway Park, North District Park, Sha Tin Park and Tuen Mun Riverside Park to promote adoption of renewable energy technologies;
installing passenger sensors for lighting at lift lobbies at different levels in Hong Kong Visual Arts Centre to reduce their operation time;
adjusting the timer lighting schedule to fit seasonal need and installing astronomical time switches to the lighting in some parks, playgrounds and civic centres so that the lighting would be switched on/off according to astronomical time of sunset and sunrise to save energy.  Besides, remote control devices were installed in some parks to switch on/off park lights by mobile phone during inclement weather; 
using photocell control in some leisure and performing arts venues to automatically control the light in response to the intensity of the natural light;
turning off the air-conditioning system in the main foyer half an hour/one hour before the close of the performing arts venues when there was no performance/activity in the venues; and
(g) for public libraries, solar control films or blinds for windows were installed as appropriate to reduce sun heat, some decorative lights were switched off, computer monitors and multimedia players at all Multimedia Information System workstations were switched off after closure of libraries. 
3.24 At the Headquarters building, the following practicable measures were also implemented –

replacing the motors and controllers of all lifts with energy efficient models;
using solar control window films at all windows of the building;
installing occupancy sensors on all floors to control the on/off of the lights;
switching off part of the lighting at G/F entrance and lobby area;
using timers to control the water flushing of urinals at male toilets;
suspending the operation of lighting at the open space car park and outdoor planter boxes;
installing carbon monoxide (CO) and nitrogen dioxide (NO2) sensors to control the speed of ventilation fan at the basement car park;
using separate electricity meters at G/F to 17/F to monitor the electricity consumption of individual floors;
carrying out surprise checks outside office hours to ensure that any unnecessary equipment was turned off while not in use; and
replacing the lights at the corridors near the female toilets at 1/F to 17/F with LED lights.
3.25 We will continue our effort to achieve the Government’s new target of saving and identify energy management opportunities specific to the operational and technical characteristics of individual buildings by conducting energy audit for buildings with annual electricity consumption of more than 500,000 kilowatt hour in 2013-14.

(III) Water Saving

3.26 The fresh water consumption of government buildings under LCSD in 2018 were 13,252,768 M3. Major water conservation measures adopted are listed below –
we exercised vigilance in the use of water by regulating outflow of water taps and replacing them with timer-taps in our offices and venues as far as possible. Any leakage of water taps were repaired as soon as possible; and
we achieved water saving by stepping up site inspections of irrigation systems to prevent water leakage, using spray nozzles for irrigation to reduce water loss from the soil surface, planting drought tolerant species at suitable locations and using less water for water features in major parks.

(IV) Waste Reduction

3.27 Waste reduction and other green measures adopted are listed below –
we promulgated on our Document Library a list of sales term contracts for waste disposal/recycling to facilitate the sale/recycling of unserviceable items;
we used recyclable and reusable office stationery, such as rechargeable batteries, recyclable ink/toner cartridges, refillable pen shafts and greener clutch pencils, etc.;
(c) we promoted the use of more green products, such as food waste compost, animal waste composts, and environmental-friendly pesticide for plants, and the recycle use of yard wastes as soil conditioner for planting;
(d) we signed the Food Wise Charter under the Food Wise Hong Kong Campaign, disseminated information on food waste reduction to catering service contractors operating in our leisure/cultural venues, and displayed posters/publicity materials which promoted the Food Wise Charter;
(e) we recycled yard waste generated from horticultural maintenance works at Animal Waste Composting Plant in Ngau Tam Mei;
(f) we reminded colleagues to plant flowering shrubs instead of seasonal flowers for beautification and landscape work so as to reduce yard waste;
(g) we placed waste separation bins (including 3-coloured, 4-in-1 bins and bottle-shaped bins) at over 720 venues, including leisure and cultural venues and the Headquarters building;
(h) for purchase of regulated products, we requested suppliers/manufacturers to provide the regulated products that are in compliance with the Volatile Organic Compound limit, including documentary proof in the quotation document;
(i) we incorporated a provision in the cleansing and horticultural maintenance service contracts that contractors shall collect and sort all refuse in an environmental-friendly manner, and remove and dispose of the refuse properly in recyclable polythene bags;
(j) we reminded colleagues to send invitation in electronic means for organising events/meetings, not to use corsages, reduce name badges to an absolute minimum and avoid using throw away paper cups and utensils as far as practicable;
(k) we reminded colleagues to help reduce the use of plastic shopping bags and avoid the distribution of reusable shopping bags (including but not limited to non-woven bags) except on a need basis in publicly funded activities;
(l) we placed umbrella dryers and umbrella racks at various venues, and 111 leisure venues and 18 cultural venues ceased to distribute plastic umbrella bags on rainy days. If provision of umbrella bags was necessary, plastic recycling bins were provided, where appropriate, to collect the used umbrella bags for recycling;
(m) we promoted "Bring Your Own Bottle" culture in the community and installed 1 376 and 24 water dispensers/ fountains in leisure and cultural venues respectively. We reminded colleagues to stop the distribution of plastic bottled water; and
(n) we conducted annual performance review to monitor the adoption of green measures and waste reduction practices by sections/offices.

(V) Carbon Reduction

3.28 As part of the Government’s efforts in combating climate change, we conducted annual carbon audits for our major buildings with annual electricity consumption over 500 000 kilowatt hour (kWh) so as to assess the carbon performance and identify room for emissions reduction. The carbon performance summary was uploaded to the Department’s website.

(VI ) Environmental Awareness among Staff

3.29 For raising environmental awareness and promoting waste reduction, saving energy and natural resources among staff – Environmental Awareness among Staff
we promoted and regularly re-circulated circulars and good practices in paper saving, energy saving, waste avoidance and reduction and improving air quality to staff and contractors. These circulars and good practices have also been uploaded onto the Department’s document library for staff’s easy reference and retrieval;
we issued to staff and new recruits green tips for offices and attending/organising events and meetings for enhancing their awareness of the green measures;
we took part in the lights out campaign of “Earth Hour 2018” organised by the World Wide Fund for Nature on 24 March 2018; and
we regularly reminded our colleagues to choose energy efficient products in line with the mandatory Energy Efficiency Labelling Scheme under the Energy Efficiency (Labelling of Products) Ordinance. 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.

(VII ) Clean Air Charter

3.30 On 27 November 2006, the Chief Executive signed the Clean Air Charter on behalf of the Government at the “Business for Clean Air” seminar organised by the Hong Kong General Chamber of Commerce. The Charter was initiated by the business sector in support of the Government’s appeal to improve air quality in Hong Kong.
3.31 As at 31.12.2018, we had a fleet of 154 vehicles. The total mileage was 1 828 703 km in 2018 and the fuel consumption was 419 731 litres. The related emissions were about 8 043 kg of nitrogen oxides (NOx) and 494 kg of respirable suspended particulates (RSP)2.  We have implemented the following measures in support of the Government’s policy to improve air quality in Hong Kong –
2. The indirect emissions from vehicle fuel are calculated according to the formulae set out in the Guide to Clean Air Charter Report Writing published by EPD in Jan 2008.
in 2018, we replaced 11 vehicles (including three small saloons, one electric car, two medium vans, two medium trucks, and three mobile library vans), in which three mobile library vans were replaced with models of Euro VI emission standard. With the replacement and in-take of more environmental-friendly vehicles, emissions and fuel consumption will be reduced;
we have a plan to replace more conventional retired departmental vehicles with fuel efficient and low emission environmental-friendly ones continuously; and
we regularly refresh all departmental drivers about eco driving skills and remind them of good practices in operating the vehicles for reducing emissions.
3.32 For improving indoor air quality (IAQ) and providing quality services to the public, we engaged EMSD to carry out proper maintenance and retrofitting works for the ventilation and air-conditioning systems at our offices and venues.
3.33 In support of the Government’s drive of improving IAQ, we also participated in the IAQ Certification Scheme and engaged accredited IAQ Certificate Issuing Body to carry out regular IAQ inspection for LCSD venues/facilities served by central air-conditioning systems wherever practicable. In 2018, around 215 LCSD venues/facilities had participated in the Scheme.

(D) Minimising Air and Noise Pollution in Organising Leisure and Cultural Activities

3.34 We monitored closely the generator and machinery installed for activities to ensure that dark smoke emission would not exceed the prescribed requirement as stipulated in the relevant Regulations.
3.35 We monitored the noise level of outdoor events and ensure that they were within the limits set in the relevant Regulations.
3.36 Following the amendments to the Smoking (Public Health) Ordinance (Cap 371) in 2006, statutory no smoking areas have been extended to cover all indoor workplaces and public places as well as some outdoor public places. The Department has implemented the smoking ban in these premises with effect from 1 January 2007.
