The Microeconomics IA was written in 2020 on the topic of Grade 5 Cars and their negative externalities. I got a 7 on this Ia, so I think it will be very helpful.

Korea Joongang News

Dec 01, 2019


The Seoul city government began to issue penalties to drivers of cars that emit large volumes of carbon dioxide in central Seoul starting yesterday as part of its ongoing efforts to curb air pollution.

Owners of vehicles that are categorized as Grade 5 in terms of emission will be fined 250,000 won ($212) when they drive in the city’s so-called Green Transport Zones, which covers areas within the Seoul City Wall, according to the Seoul Metropolitan Government.

The area within the Seoul City Wall, or Hanyangdoseong, that follows the four mountains surrounding the center of Seoul, as well as four main gates, includes 15 neighborhoods in the Jongno and Jung Wards.

The restriction will be in effect from 6 a.m. to 9 p.m. daily, with 119 surveillance cameras installed in 45 places that connect roads to the green zone.

Grade 5 cars owned by drivers with disabilities, emergency vehicles and those equipped with diesel particulate filters will be exempt from the scheduled restriction.
