4 Actions Required for a Low Carbon Era Global – International agreement National – China’s national plan Local – Hong Kong’s Climate Change Strategy and Action Agenda
5
5 Vision and Opportunities in the Green Pearl River Delta (PRD) Region Vision : transform the PRD into a low-carbon, high technology and low pollution cluster of cities Opportunities : low carbon infrastructure, energy efficient buildings, cleaner energy applications
6
6 Hong Kong’s Climate Change Strategy and Action Agenda
7
7 With the achievement of the targets : Hong Kong’s annual greenhouse gas (GHG) emissions will be reduced from 42 million tonnes in 2005 to 28-34 million tonnes in 2020, representing an absolute reduction of 19-33%. Per capita emission will drop from 6.2 tonnes to 3.6 – 4.5 tonnes, representing a reduction of 27-42%. Hong Kong’s Target (2020) Carbon intensity reduction 50-60%
8
8 GHG Emissions in Hong Kong Our Emissions in 2008 : 42 million tonnes CO2 equivalent
9
9 Climate Change Action Agenda - carbon mitigating measures Maximising Energy Efficiency (esp. in buildings) Greening Road Transport Promoting use of Clean Fuel for Motor Vehicles Turning Waste to Energy Revamping Fuel mix for Electricity Generation
10
10 Opportunities and Challenges for Construction Industry Opportunities: Increasing demand for energy efficient buildings New construction technology New construction materials New approach to design buildings Continued investment in low carbon infrastructure Railways, district cooling systems, waste-to-energy facilities Challenges: A relatively short period of time Costs / Benefits distribution Acceptance of clients
11
11 District Cooling System at the Kai Tak Development Cooling capacity : 284 MW cooling energy Air-conditioned floor area : 1.73 million square metres
12
12 Sludge Treatment Facility Treatment Capacity:2000 tonnes per day Feature – Education Centre & Community Facilities etc Commissioning Date : 2013
13
13 Key Vulnerable Areas Biodiversity and nature conservation Built environment and infrastructure Business and industry Energy supply Financial services Food resources Human health Water resources
14
14 Framework of Adaptation Options Monitoring Institutional Strengthening and Capacity Building Disaster Management and Emergency Planning Research and Investigation Education and Public Awareness
15
15 Policy Address 2010-2011 Proposed fuel mix for power generation by 2020 – natural gas about 40%, – coal no more than 10%, – renewable energy about 3-4%, – imported nuclear energy about 50% Having zero emission franchised buses is the ultimate policy objective – To assist testing hybrid buses or other greener buses – To assist retrofitting old buses with devices to reduce emissions – To designate pilot low-emission zones for buses Promoting green buildings – To raise building energy efficiency standards – To require developers to provide environmental and energy consumption information of buildings for the reference of potential users.
