For the next four months starting in December, an alternate no-driving system in the public sector will be introduced to the metropolitan areas in South Korea. The government has legislated to protect people’s health against fine dust. The cars with emission grade 5 will be restricted from operating in the capital area except for vehicles for the disabled, emergency vehicles, etc. The vehicles with emission grade 5 are the vehicles that emit significant amounts of carbon based on the Rules for Calculation of Automobile Exhaust Gas Grades, and about 1.14 million vehicles are the target of this. The alternate no-driving system includes both public and employee vehicles, except for vehicles essential to public service. On the day when the concentration of ultra-fine particles is high, all vehicle operations for administrative and public officials will be suspended also. The driving restrictions in some areas of Seoul will be gradually expanded to the greater metropolitan areas starting from December. Similarly, the government will install air purification equipment in every kindergarten and school classroom for vulnerable social group’s health this year. The government will also focus on the air quality of daycare centers, nursing homes, and subway stations. Many people are looking forward to the consequence of the government’s efforts to reduce fine dust.
