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

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%

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

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

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.
