SEOUL, SOUTH KOREA, April 11, 2018 — The Seoul Metropolitan Government reduced 235.9 tons of fine dust (PM-2.5) through its constant air quality improvement programs in recent three years, and it is estimated that it will reduce 172.6 tons in 2018 alone. This is equivalent to about 12.3 percent of the total emission amount of 3,316 tons of PM-2.5 produced in 2013.
Given various programs the city government is carrying out, yet are difficult to analyze their quantitative effects, such as the distribution of eco-friendly vehicles, the traffic demand management, and the operation of the low emission zones where pollutant-producing vehicles are prohibited from entering or subject to a fine, the betterment experienced by the citizens can be more significant.
It is also projected that the reduction amount of PM-2.5 by sector from 2015 through 2018 will be 262.1 tons from automobiles; 122.5 tons from construction machineries; 21 tons from scattering dust; and 2.9 tons from heating power generation.
Compared to that of 2013, the PM-2.5 reduction ratio by sector has been increased by 35.8% in automobiles and by 19.9% in construction machineries, which proves the effectiveness of the city government’s continuous efforts in low environmental pollution programs for cars and construction machineries.
As part of the low pollution programs for vehicles, the Seoul Metropolitan Government supports subsidies for early scrapping of diesel vehicles registered before 2005, smoke reduction device installation, LPG engine modification, and PM-NOx reduction device installation.
The city government also provides financial support when smoke reduction devices are installed on five kinds of construction machineries including excavators registered before 2004, and engines of forklift trucks and excavators are modified.
In addition, it has reduced the amount of PM-2.5 in scattering dust by 1.5 percent from 2013 by expanding the number of dust-cleaning vehicles on the street and strengthening the management of the dust-producing businesses. Currently 92 dust-cleaning vehicles clean an average of 4,000 kilometers of roads in Seoul a day. It is expected to add more 30 cleaning vehicles in 2018.
Large-scale construction sites with an area of 10,000 square meters or more are designated as priority management targets for scattering dust, and the management and supervision of them are being strengthened. Besides, the Seoul Metropolitan Government makes an effort to decrease the scattering dust through the urban and school greening project and the eco-friendly parking lot pavements.
According to the Environmental Impact Assessment Criteria revised by the Seoul Metropolitan Government, high-efficiency energy equipment and low-knock burner certified products should be installed on combustion facilities, such as water heaters and boilers, and eco-friendly boilers with a nitrogen oxide emission level of 1 grade (40ppm or less) is mandatory to be installed on individual heating facilities, if a building has an area of 100,000 square meters or more.
The Seoul Metropolitan Government said it will continue to do its best so that the citizens are able to experience a better air quality by reducing the PM-2.5 density to 20μg/m3 by 2020 and to 15μg/m3 by 2025 through its constant air quality improvement programs.
