STATUS OF URBAN AIR QUALITY IN THE ASIA – PACIFIC REGION Air quality of cities in the region among the worst in the world Total Suspended Particulates (TSP) exceeds WHO Guidelines in many cities (Bangkok, Beijing, Calcutta, Delhi, Jakarta, Manila, Mumbai, Shanghai, Tehran) SO 2 and NO 2 also high in some cities SO 2 – Beijing, Pusan, Tehran, Yokohama NO 2 – Calcutta, Osaka, Seoul, Shanghai, Tokyo Includes outdoor and indoor sources 3
STATUS OF URBAN AIR QUALITY IN THE ASIA – PACIFIC REGION (Cont’d) Without urgent interventions air pollution will increase in future Main causes: Rapid urbanisation Growing energy needs Industrial growth Traffic increase particularly 2 & 3 wheelers Biomass/Coal burning 4

STEPS TAKEN TO CONTROL URBAN AIR POLLUTION IN THE ASIA-PACIFIC REGION (Cont’d) REGULATORY MEASURES Standards and Regulatory Authorities Enforcement-Stringent (Japan and Singapore) Phased (People’s Republic of China, India, Indonesia, Republic of Korea, Thailand) Public Awareness and Judicial Action (India) Environmental Impact Assessments (EIA’s) (People’s Republic of China, India, Japan, Pakistan, Thailand) Zoning Regulations (India, Japan, Singapore) 11
STEPS TAKEN TO CONTROL URBAN AIR POLLUTION IN THE ASIA-PACIFIC REGION (Cont’d) ECONOMIC INSTRUMENTS Taxes Based on Pollution Load Taxes for Using Leaded Gasoline Subsidies Tax Incentives for Cleaner Fuel Use 12
STEPS TAKEN TO CONTROL URBAN AIR POLLUTION (Cont’d) TECHNOLOGICAL IMPROVEMENTS/ CLEANER PRODUCTION ECONOMIC INSTRUMENTS Energy Efficient Industrial Processes Fuel-efficient Stoves Energy Efficient Appliances and Lighting Electrostatic Precipitators in Power Plants Cleaner Alternative Fuels Unleaded and low sulphur motor fuels Liquefied natural gas (LNG) 13
STEPS TAKEN TO CONTROL URBAN AIR POLLUTION (Cont’d) TECHNOLOGICAL IMPROVEMENTS/ CLEANER PRODUCTION ECONOMIC INSTRUMENTS Catalytic Converters Electric Vehicles Wind Power Photovoltaics 14
EFFORTS AT AMELIORATION AND CONTROL OF URBAN AIR POLLUTION (A) CURATIVE Enforce regulations stringently Adopt suitable best practices from other cities Identify and reduce air pollution loads by source Encourage public transport use Make cleaner fuel use mandatory - ban leaded gasoline and high sulphur diesel Encourage bi-fuel, electric and LNG vehicles Identify and reduce sources of indoor air pollution 15
EFFORTS AT AMELIORATION AND CONTROL OF URBAN AIR POLLUTION (A) CURATIVE (Cont’d) Ensure local industries have adopted cleaner production methods are not feasible Strengthen local authority initiatives and enhance partnerships Encourage intercity cooperation Enhance cooperation between local and national governments Enforce vehicle inspection and maintenance Institute better traffic management and procedures 16
EFFORTS AT AMELIORATION AND CONTROL OF URBAN AIR POLLUTION (B) PREVENTIVE Obtain political commitment (macro policy) Draft and adopt suitable regulations and standards Identify and adopt appropriate technologies Promote environmental education and public awareness Invite stakeholder participation in pollution reduction activities Seek consensus on actions 17
EFFORTS AT AMELIORATION AND CONTROL OF URBAN AIR POLLUTION (B) PREVENTIVE (Cont’d) Ensure proper project component appraisals Ensure adequate training of local environmental administration staff Encourage private sector participation in air quality management initiatives Identify key pollutants, sources, institutions, stakeholders Supervise implementation and draw upon experiences from lessons learned 18
EFFORTS AT AMELIORATION AND CONTROL OF URBAN AIR POLLUTION (B) PREVENTIVE (Cont’d) Promote pro-active land-use planning Explore least cost solutions - undertake economic analysis of options Reduce open burning Reduce dust on roads 19
EXAMPLES OF SUCCESSFUL & TRANSFERABLE PRACTICES Kitakyushu City, Japan (Port City, Fukoka Prefecture) Population: 1. 01 million (1998) Major Product: Heavy industries high tech industries & general and precision machinery Pollution: High concentrations of SO 2, NO 2 and TSP due to heavy industries introduced in 1960’s 20
