South Korea's pollution: caused by China?
South Korea's air pollution is an increasing threat to its people and environment. The country has the worst air quality of the 35 richest countries in the OECD. South Koreans are concerned about the effects of pollution on their health, with 97% of people surveyed by the Ministry of Environment saying that air pollution was causing them physical or psychological pain.
There are many sources of air pollution in South Korea, both domestic and international. The country's rapid industrialization has led to growing pollution in its large cities, with Seoul being named one of the world's cities with the worst air pollution. Fossil fuel combustion is the largest contributor, with the country's expanding industries and increasing number of vehicles on the road relying heavily on oil and coal. South Korea's economy has also been fuelled by dirty coal-fired power stations, which, along with vehicle emissions, have contributed to the country's poor air quality.
China has been blamed for South Korea's pollution problem. Studies have suggested that as much as 60% of South Korea's air pollution comes from China, with higher concentrations on "bad air quality" days. During the colder months, slow air currents mean that pollutants from China are not dispersed, leading to smog-like conditions in South Korea. Dust storms from western China and Inner Mongolia, which occur every spring, have been linked to respiratory diseases, cardiovascular diseases, and other health problems in South Korea.
However, it is important to note that South Korea's domestic air pollutants also contribute significantly to the country's poor air quality. While China has implemented policies to reduce its air pollution, such as its war on pollution in 2014, South Korea must also take action to reduce its emissions and improve the health of its citizens.

South Korea's pollution: domestic factors
South Korea's air pollution is an increasing threat to its people and the environment. The country's rapid industrialization has resulted in many forms of pollution, especially in its cities. Seoul, the nation's largest city, has the worst levels of air pollution in South Korea, and its residents will live 1.7 years less if pollution levels are not remediated.
Fossil fuel combustion is the biggest contributor to air pollution in South Korea. The country has minimal fossil fuel resources and imports all but 1% of its coal supplies. Oil accounts for 38% of the primary energy supply, coal for 29%, and gas for 15%. Conventional power plants that combust fossil fuels release hazardous gases such as oxides of nitrogen, carbon monoxide, particulates, and hydrocarbons into the air. South Korea's 57 coal-fired plants account for 41.9% of the total electricity generation and are a major source of air pollution. The country has the highest share of super and ultra-supercritical power plants worldwide.
The number of vehicles on Korea's roads is increasing rapidly, and the growth of imports and exports in its fast-growing economy increases fossil fuel combustion. The expansion of industries and the economy has led to more delivery vehicles in cities, usually powered by diesel, a particularly dirty fuel. In 2015, South Korea was ranked as the world's 11th largest gross domestic producer, a position attained through dirty coal-fired power stations and dirty vehicle emissions.
The Korean government has taken steps to improve air quality, such as implementing the Special Act on Seoul Metropolitan Air Quality Improvement in 2003. The government enforces regulatory limits on 11 air pollutants and 32 hazardous air substances, and plans to modify enforcement rules under the Clean Air Conservation Act to strengthen standards for fine dust watches and warnings. The government also intends to retrofit coal-fired plants with carbon dioxide capture and storage (CCS), selective catalytic reduction (SCR), and flue gas desulfurization (FGD) systems. In July 2022, the Korea Ministry of Trade, Industry, and Energy announced further air pollution control measures by targeting the closure of 30 coal-fired power plants by 2034.

China's pollution policies: impact on South Korea
China's pollution policies have had a notable impact on South Korea, with improvements in air quality in China leading to a reduction in transboundary pollution affecting its eastern neighbour. South Koreans have long expressed concerns about the hazardous "fine dust" pollution in their country and its potential origins in China.
Studies have suggested that a significant proportion, ranging from 30% to 60%, of South Korea's air pollution comes from China's industrial sites and coal plants. Prevailing westerly winds, particularly during the fall and winter months, carry air pollution from China towards South Korea, resulting in higher pollution levels in the northwest region of South Korea compared to the southeast. This transboundary pollution has been estimated to contribute to increased mortality rates in South Korea, with approximately 300 fewer deaths for every million people annually attributed to China's pollution reduction efforts.
China's nationwide air pollution reduction program, implemented since 2014, has yielded positive results. Between 2015 and 2019, the program led to a 9.6 microgram per cubic meter decrease in transboundary air pollution from China to South Korea. This reduction in pollution from China has had tangible health and economic benefits for South Korea, saving the country more than $2.6 billion per year.
However, it is important to note that South Korea also faces domestic pollution challenges. The country's reliance on fossil fuels, particularly coal and diesel, contributes significantly to air pollution, especially in urban areas. The increasing number of vehicles, including diesel-powered delivery vehicles, and the use of coal-fired power stations have been identified as major sources of pollution within South Korea.
Addressing these domestic issues is crucial for South Korea to effectively tackle its pollution problem. While China's pollution policies have positively impacted South Korea, collaboration and joint efforts between the two countries are necessary to address the complex and cross-border nature of air pollution in the region.
