According to the nation’s Yonhap news agency, the government believes the step could reduce emissions of fine dust particles smaller than 10 micrometres.
As part of a wider government initiative to address air pollution, the Ministry of Trade, Industry and Energy has opened consultations on the possibility of shutting down older coal-fired plants, building new liquefied natural gas (LNG)-fired plants, and cutting emissions at existing plants.
The government is working on a plan which would see plants over 40 years old shut down, Korean media reports said.
South Korea boasts 53 coal-fired power plants, three of which have been operational for over 40 years, and 11 of which are more than 30 years old.
The nation has plans in place to build 20 new coal-fired plants by 2021, although plans for four such plants were shelved after December’s global climate summit in Paris.
