Benchmark of low-carbon -Urbandevelopment - Resort beach - Define the environmental target -Tourism 4. LCMT Introduced d measures - Prepare a low-carbon Guideline - Evaluate cost of CO2 reduction - Select CO2 reduction measures With the sustainable development of the future, the realization of attractive and innovative urban development!! 4

5 Legal Framework and Policies in Da Nang City 1) Da Nang s master plan for socio-economic development up to ) A General Plan for in Da Nang City 3) Building Da Nang City as An Environmental City (Aug. 2008) Based on the Agenda 21 of Viet Nam government (PM Decision, 2004) To aim at a sustainable development with the target year 2020, To develop many different environmental issues such as: air pollution reduction, waste treatment and recycling, energy conservation, and renewable energy. However, not indicate any scope and measure challenging climate change issues, GHG emission reduction and low-carbon city. 1) "Carbon Emission Situation Study at Da Nang City (2011) cooperated by Asian Institute of Technology (AIT) 2) "Action Plan in Responding to Climate Change and Sea Level Rise for Da Nang up to 2020" financed by Rockefeller Foundation 3) Sustainable Urban Energy Program (2011 to 2013) cooperated by Aus AID and World Bank 4) "Low-carbon Model Town Project Phase 3 " (2013) by APEC Policy development 5

11 Categories Establishment for Creating a Low Carbon Town Possible low carbon measures for Ngu Hanh Son District in Da Nang City can be divided into nine categories listed below: (1) Buildings (2) Transportation (3) Energy - Energy Management System (4) Energy - Area Energy Network (5) Energy - Untapped Energy (6) Energy - Renewable Energy (7) ICT Control (8) Environment (9) Water Supply ppy and Sewage 11

12 Categories and Possible CO2 Reduction Measures for Example 1. Buildings - Introduction of a system of comprehensive environment benchmarks that target buildings. etc. 2. Transportation - Facilitation of the spread of electric motor-bakes and charging facilities. etc. 9. Water Supply and Sewage - Bio generation by utilization of water treatment sludge. etc. 8. Environment 8 Planning - Making environmental initiatives visible visible. etc. 7. ICT Control - Optimized control of traffic flow due to an ITS (intelligent transportation system). etc. 23 Possible CO2 Reduction Measures 6. Energy - Renewable Energy - Purification and power generation utilization of biogas (digestive gas). etc. 3. Energy - Energy Management System - Stabilization of the electric power supply by a high capacity electrical storage facility. etc. 4. Energy - Area Energy Network - Heat pump style cooling system that uses river water and ocean water. etc. 5. Energy Untapped Energy U t de - Power supplied by renewable energy from wind power and d solar l power. etc. 12

13 Four Viewpoints for Determining Guidelines With these ideas in mind, the following four points are established as a guideline (evaluation viewpoints) in order to create a low carbon town in Ngu Hanh Son District Viewpoint 1: measures by which a large volume of CO2 reductions are expected. Viewpoint 2: measures whose cost-effectiveness is large. Viewpoint 3: measures that may contribute to solving the area s current challenges in addition to global warming. (*1) Viewpoint 4: measures that may lead to sustainable development and increasing attractiveness. (*2) (*1) The main current challenges are Re-development, Sprawl, Deterioration of the landscape and Energy supply. (*2) The main attractiveness is Low carbon town, Resort beach, Tourism and Sustainable. 13
