(5)Statistics show that air quality improved by 6-43% from 2017 to 2021: Analysis of air quality data for the past five years in Taipei City shows that as of the end of November, 2021, the air quality has shown a trend of improvement year by year compared with that in 2017, with manual PM2. 5 From 15.3 μg/m3 to 11.8 μg/m3, an improvement rate of 23%; sulfur dioxide from 2.8 ppb to 1.6 ppb, an improvement rate of 43%; nitrogen dioxide from 19.7 ppb to 14.4 ppb, an improvement rate of 27%. The high value of ozone in 8 hours (93%), which is reduced from 62.9 ppb to 59.4 ppb, and the improvement rate is 6% 2. Integrate the achievements of the Taipei Clean Air Action Plan In order to enable citizens to enjoy healthy air, the city government team worked tirelessly to achieve the World Health Organization’s recommended PM2.5 annual average of 10μg/m3 in 2030. Clean Air Project 2.0", through the three major aspects of "low pollution, green transportation, and regional joint defense", this project assists in the compilation of the results of the ten major action plans as follows: (1) The introduction of a high-polluting vehicle control platform, scientific and technological law enforcement to inspect highly polluting vehicles, increase the regular inspection rate of locomotives by about 73% by November 2021, and set up the first phase of the empty maintenance zone according to local conditions, starting from January 1, 2021 Implementation; (2) As of November 2021, Taipei City has eliminated 2,608 large diesel vehicles of Phase 1~3, and installed 352 sets of smoke filters (including 187 sets of environmentally friendly clean vehicles and 165 sets of other public service departments) (3) According to statistics, from 2016 to November 2021, about 113,000 two-stroke locomotives have been eliminated, and there are about 32,000 remaining in the city. (4) A total of 48 electric buses were on the road in May 2021, and the goal was to fully electrify buses in 2030. (5) In 2019, the first phase of 16 commercial districts (accounting for 10.2%) has been completed, and from 2019 to 2021, the second phase of the implementation of the second phase of MRT stations will complete the city's 27% of the city's roadside locomotive parking space charges. (6) As of November 2021, 610 charging and replacement stations have been completed, and the construction density has reached 2 locations per square kilometer. According to statistics, as of November 110, 1,507 electric motor vehicles have been purchased, accounting for 25.5%. In 2021, the goal is to fully electrify official vehicles. (7) The Capital Monitoring Network of 1 Administrative District and 1 Station has been completed. (8) Announce the technical guidelines for oil fume and odor control equipment in the catering industry, and by May 2021, A total of 840 restaurants under the threshold of catering management. The ratio of air pollution control facilities is 96.3%. (9) Stricter boiler sulfur oxide emission standards, from 300ppm to 50ppm, and all heavy oil boilers have been eliminated. (10) Units 1 and 2 of Xiehe Power Plant were decommissioned at the end of 108, and Units 3 and 4 should be decommissioned in 113 as scheduled. 3. Promote the control measures of mobile pollution sources in Taipei's air quality maintenance zone Air quality maintenance zone design and promotion, the second phase of the "Air Quality Maintenance Zone Mobile Pollution Control Measures Plan" was developed; The management unit consultation meeting and expert consultation meeting have been handled in August 2021. The control measures will be announced in October 2021, and the follow-up statutory operating procedures will be promoted. The announcement will be implemented on January 1, 2022. 4. Suggestions for improving the 8-hour value of ozone control The changes in O3 concentration in the city in the past five years show that the hourly ozone value has reached air quality standards. The 8-hour value of ozone is 61.8 ppb, which is slightly higher than the air quality standard of 60 ppb. The future control goal is to reduce the eight-hour ozone concentration and achieve a secondary prevention zone. O3 precursors are nitrogen oxides and VOCs. The ozone pollution form in this city is VOC-limited. Reducing NMHC emissions should be the best way to solve the O3 problem. The air quality improvement effect of mobile source VOC reduction of 35% is simulated in the empty product mode. The simulation results show that the VOC reduction can reduce an average of 3.7 ppb for the high value of 98% of ozone in 8 hours, and the reduction rate is about 4%. It is conservatively estimated that the PR93 value of ozone meets the standard, and it is necessary to reduce the VOC reduction of the city's mobile pollution sources by 30%. The VOC reduction target is 6,852 metric tons * 30% = 2,056 metric tons. The city promotes ozone precursor reduction operations, planning short-term and mid-term reduction measures for nitrogen oxides and VOC; in terms of long-term strategies, the city’s VOC emission structure shows that VOC emissions from mobile sources (including automobiles and locomotives) are The second largest source of emissions is to promote the reduction of VOCs from gasoline vehicles. It should be based on the country's long-term control goals and the process of vehicle electrification technology updates to promote vehicle electrification and reduce VOC emissions from fuel-fueled vehicles. 5. Revised Taipei City’s Air Pollution Control Plan The city’s air pollution prevention and control plan is written in accordance with Article 7 of the Air Pollution Law, and is coordinated with the National Environmental Protection Agency’s "109-112 Air Pollution Prevention and Control Plan" national control goals and implementation strategies, according to the city’s urban characteristics To set air quality and pollutant reduction targets, and achieve the goal of air quality improvement and maintenance through the planning and implementation of various air pollution prevention measures.
