In the tasks related to the National Air Pollution Improvement Implementation Plan (hereinafter referred to as NIP, or the Plan), the draft of new Plan for 2024 to 2027 has been developed. The new NIP focuses on continuous improvement of air quality, precise control of regional and seasonal air quality, and assessment of the impact of major national policies on air quality, and continues to promote air pollution prevention and control work pragmatically. The Plan focuses on eight aspects: (1) Refinement of industry reduction technology, (2) Overall control of on road vehicles and off-road engines, (3) Constructing cross-ministerial project management, (4) control of regional development, (5) Strengthening response in autumn and winter, (6) Linking to net-zero emissions and pollutant reduction, (7) Conduct economic incentives strategy, and (8) Comprehensive management. A total of 35 control strategies and 94 corresponding control measures were developed. The proposed countermeasures include control measures for the central and southern counties as well as autumn and winter seasons, and are linked to the national net-zero emission policy to obtain the possible pollution reduction effects of carbon reduction. At the same time, through the integration and management of resources across ministries, the resources can be fully utilized and the efficiency of air quality improvement can be improved. The actual implementation results of various reduction measures in the NIP of 2020 to 2023 are regularly compiled. In the work related to Local Air Pollution Prevention and Control Program (hereinafter referred to as SIP, or Local Program), we have assisted the Taiwan EPA to complete the review of 2020 to 2023 SIP for all county, as well as to organize the implementation results of the 22 counties. At the same time, refer to the content of the new NIP to revise the writing and review guidelines of Local Program. In the work on the impact of net zero carbon emission planning strategies on air quality improvement, based on the collected UK, Japan, South Korea and Taiwan’s’ 2050 net zero emission path planning, carbon reduction strategies and their impact on air quality improvement are analyzed.
