Greenhouse Gas Emissions in Hong Kong
Greenhouse Gas (GHG) emission levels:



Total emissions at some 45 million tonnes CO2
equivalent in 2006
Carbon intensity at 30kg CO2 equivalent per HKD1,000
GDP (2006), 40% reduction from 1990.
Per-capita emissions at approx. 6.6 tonnes CO2
equivalent (down 4% from 1990)

lower than those of developed economies –
USA (24 tonnes), Australia (28 tonnes), UK (11 tonnes),
EU (11 tonnes), Japan (10 tonnes), and Singapore (9
tonnes)

Hong Kong’s International Obligations





United Nations Framework Convention on Climate Change
(UNFCCC) and its Kyoto Protocol extended by CPG to Hong
Kong in May 2003
“Common but differentiated responsibilities” – a core
principle underpinning UNFCCC
Kyoto Protocol assigned mandatory emission limits to
developed countries (Annex I Parties to UNFCCC) –
combined GHG emissions from them between 2008-2012
should be reduced by at least 5% below the 1990 levels
For non-Annex I Parties such as China (including Hong
Kong), Singapore, South Korea - no requirement to meet
mandatory emission limits under the Kyoto Protocol
Hong Kong’s International Obligations


Under UNFCCC, Hong Kong is required to:
– Prepare emission inventory of GHG by sources
and sinks
– Formulate, implement and regularly update
programmes on mitigation and adaptation
measures
– Strengthen scientific research and promote
application of technologies
– Promote public awareness and understanding of
climate change and its likely effects

Hong Kong is already a small emitter
A service economy - no energy intensive
industries
Public mass transport system is very efficient
(90% of daily passenger trips are already made
on public transport system)

GHG Emissions Reduction in Hong Kong
Constraints & Opportunities

10
Dominant share of energy sector emissions
suggests the key measures should target at
electricity generation
GHG Emissions Reduction in Hong Kong
Constraints & Opportunities

11
Topography and physical
constraints limit the
potential for large-scale
development of
renewable energy,
including off-shore wind
farms
GHG Emissions Reduction in Hong Kong
Constraints & Opportunities

Scope for Hong Kong to do more
in end-use energy conservation
and efficiency:
–
–
12
Energy efficiency: better
building design and wider use
of energy efficient appliances
Energy saving: raising public
awareness and education
Electricity consumption


Promote energy conservation &
efficiency

Promote use of water-cooled A/C
systems and other energy efficient
installations

Enhance building efficiency

Building Energy Codes
–
District Cooling System
Tackling Climate Change
Existing Efforts

Use cleaner and more efficient land
transport
Utilise landfill gas as fuel

Collect and utilise landfill gas from closed
and operating landfills as fuel substitutes
for on-site use
– Export landfill gas from the Shuen Wan
Landfill and NENT Landfill as fuel for the
Towngas Production Plant in Tai Po
Utilise biogas at sewage treatment works

Tackling Climate Change
Existing Efforts

Tree plantation
programme to enhance the
carbon sink

12 million trees were planted
in the past 5 years
1.2 million trees will be
planted in 2008
Tackling Climate Change
Public Participation




17
Promote lifestyle and behavioural
changes in the community
Mobilise community action to
adopt energy saving measures
Continuous public awareness
programmes
Outreaching to schools through
talks, web-based education kits
and joint activities
Tackling Climate Change
Government Taking the Lead

Reducing electricity consumption
–
–
–
18
Cut down electricity consumption of Government
by 6% between 2002/03 to 2006/07
Pledged further in the 2005-06 Policy Address to
reduce 1.5% electricity consumption of all
Government office buildings from January 2006
Energy audits and re-audits conducted in over
200 major Government venues, with follow up
energy savings projects implemented

Tackling Climate Change
Recent new efforts
New Measures since October 2007
 Launch first carbon audit guidelines for buildings and
“Green Hong Kong ‧Carbon Audit” campaign
 Prepare for mandatory compliance with Building Energy
Codes
 Roll out Mandatory Energy Efficiency Labelling Scheme
 Promote the use of biodiesel
 Conduct a study on climate change with a view to
enhancing the existing mitigation & adaptation measures
