1 Air Quality Improvement and Prospects of Shenzhen City Human Settlements and Environment Commission of Shenzhen Municipality Fusan, Korea 深圳市人居环境委员会 (HSECSM)

2 生产总值 ( 亿元 ) 第三产业比例 (%) General Information of Shenzhen City Geographical and Meteorological Conditions Shenzhen is a coastal city in South China with an area of 1992 km 2 Summer is mainly influenced by clean air current from ocean; autumn and winter is mainly influenced by inland pollution air mass transmission. GDP and Population GDP: $26.9 billion (2015) Resident population: million (2015) Industrial Structure Developing Strategic Emerging Industry Thrice industrial structure was adjusted from 0.7:49.7:49.6 in 2000 to 0.03:41.2:58.8 in Energy Structure Pursuing Clean Energy Policy 10,000 yuan GDP energy consumption decreased from 0.593t standard coal in 2005 to in 第三产业生产总值 第一产业生产总值 第二产业生产总值 第三产业比例

3 Haze days Visibility,Km Air Pollution Control Process 1990s Pollution control started Large point sources control Expansion of key sources control New sources control Routine testing and inspection of pollution sources seawater desulfurization of coal power plant Research of air pollution control plan Blue Sky Action Power plants, boilers, vehicles and dust control Shenzhen Universiade in 2011 VOCs, Vessels and non-road mobile machinery control year Pollutants emissions increased and air quality decreased since the 1990s,and haze days reached peak of 184 days in since then, air quality has kept improving, haze days dropped to 35 days in 2015.

4 Shenzhen Air Quality Enhancement Plan Shenzhen Air Quality Enhancement Plan released on September 20, 2013 and was the most stringent air pollution control program in history which covered 10 major areas and included 40 measures Air quality improvement measures measures for power plants (3 items) measures for industrial sources (4 items) measures for vehicles (7 items) measures for vessels (5 items) measures for non-road mobile machinery (3 items) measures for VOCs sources (11 items) measures for dust sources(5 items) measures for other sources (2 items)

5 Present Situation of Air Pollution Sources Vehicles Vessels and Ports Non-Road Mobile Machinery VOCs Sources Power Plants Fuels Dust Sources Travel prohibition: gasoline vehicles below Europe I and diesel vehicles below Europe Ⅲ Emission Standards Gasoline and partial heavy diesel vehicles implement National V Emission standards Gasoline and diesel fully implement Europe V Oil Standard. Popularized 34,000 new energy vehicles. 7% of vessels used low sulfur oil with the sulfur content 0.1%m/m when berthed. Completed oil-to-gas conversion for 40% intra-port trailers and oil-to-electricity conversion for most gantry cranes. Piloted installation of DPF Implemented Euro Ⅲ(A) standards More than 200 enterprises used water-based paints or inks More than 400 enterprises carried out end treatments Prohibit the use of high volatility building paints Gas thermal power plants performed low nitrogen burners transformation, NO x emission concentrations were about 40mg/m 3. Coal-fired power plant( 180MW) finished super clean transformation, SO2 and NOx emission concentrations were about 10 and 30mg/m 3. Prohibit the use of high pollution fuels since July 2011 residents used gas completely, part of industrial boilers used biomass fuels Construction sites larger than 50,000 m 2 mostly finished the installation of video surveillance system The average machinery-cleaning ratio of municipal roads was 88.3%.

6 Regional Air Pollution Joint Control Strengthen joint control with surrounding cities under the framework of air pollution control in Guangdong Province Established a regional cooperation mechanism among Shenzhen, Dongguan and Huizhou cities. Significant projects notification system Information sharing of pollution sources Synchronous start emergency pollution weather warning Co-control of vehicle emissions Cooperation to promote new energy vehicles VOC emissions control Low-nitrogen transformation for gas thermal power plants Avoid opening burning of high polluted fuels and biomass

8 浓度 ( 毫克 / 立方米 ) Concentrations,μg/m3 Concentration Various of Air Pollutants Various of PM 2.5 annual concentration University City point Citywide average PM 2.5 concentration went down sharply, 62µg/m 3 in 2006 to 30µg/m 3 in 2015 SO 2 NO 2 PM 10 concentration declined substantially over the past decade Year SO2 NO2 PM10 O3 PM2.5 Ozone annual average value remains at high level, and more frequently occurs as daily primary pollutant, indicated strong atmospheric oxidizing capacity 年份

9 The status of Air Pollutants Emission PM 2.5 source apportionment(2014) Regional transport /local emission :0.51/0.49; Primary and secondary source:0.4/0.6 Composition of local PM 2.5 concentration Primary source:mobile source (40.3%); Major sources: industrial process, fugitive dust, ocean going vessel and power plant (15%,12%,11% and 8%) Results of the air pollutant emission inventories (2014) Mobile source (Red) Primary source of the SO 2 NOx CO BC and OC emissions(80.7%,87.6%, 87.2%,89.3% and 61.3%); Fugitive dust source(green) Emissions(KT) Primary source of the PM 10 PM 2.5 emissions (76.2% and 48.5%) Solvent utilization sources(yellow) Primary source of the VOC emissions (49.7%)

10 Air Quality Target for 2020 The concentrations of air pollutants try to reach the second stage targets of the Air Quality Guidelines of WHO comprehensively (annual average concentration of PM 2.5 will reach 25μg/m 3 ), WHO transition period target value is stricter than the national Class II standard (NO 2 excluded). In 2015, proportion of days with air quality up to the national Class II standard of Shenzhen stood at 96.3%, days with PM 2.5 as principal pollutant were 5. If referring to WHO Stage II target value, proportion of days up to the standard was 87.7%, and days of PM 2.5 as principal pollutant increased to 30. Pollutant µg/m 3 Air Quality Guidelines of WHO (IT-2) (Avg.year/Avg.day ) National Class II (Avg.year/Avg.day) Annual average of 2014 Annual average of 2015 PM /50 35/ PM 10 50/100 70/ O 3 160(IT-1,8h) 160(8h) NO 2 40/-- 40/ SO 2 --/50 60/

11 Key Measures for Air Pollution Control VOCs pollution control Vehicles pollution control Dust pollution control Regional joint control Prohibit the use of highvolatility paints in the coating industry Complete low-volatility raw material modification or waste gas treatment for printing and bonding process Prohibit the use of highvolatility cleaning agents, building coating and commercial organic solvents Control organic waste leakage in oil and gas storage and transportation process Quantity regulatory policies and DPF installation for diesel vehicles Raise vehicle emission and fuel standards Buses and taxis mandatory use of new energy vehicles Eliminate old gasoline and diesel vehicles Strengthen supervision on dust pollution sources such as construction sites, concrete batching plants and gravel materials yards Promote the fullyenclosed new energy dumpers Enhance the cleanliness level of various urban roadways, install TSP online monitoring system Implement unified polices of outdated production facilities eliminatio n, high-polluted fuels control and in-use vehicles management Promote lowvolatile paints in major coating industries Avoid opening burning of household wastes, garden wastes and straw
