Air pollution from coal-fired power plants and vehicle emissions
South Korea has 57 coal-fired plants, which account for 41.9% of the country's total electricity generation. Coal-fired power plants are a major source of air pollution in South Korea, and the country has the highest share of super and ultra-supercritical power plants worldwide. The South Korean government has taken measures to address this issue, including retrofitting plants with carbon dioxide capture and storage (CCS) systems, selective catalytic reduction (SCR), and flue gas desulfurization (FGD) systems. Additionally, the government has announced plans to close 30 coal-fired power plants by 2034, with 24 of them being renovated as natural gas-fired power plants.
Vehicle emissions also significantly contribute to air pollution in South Korea, particularly in large cities like Seoul. The main pollutant of concern is nitrogen oxides (NOx), which are known to act as precursors to the formation of tropospheric ozone and secondary fine particles (PM2.5). The South Korean government has continuously reinforced emission regulations for newly manufactured vehicles, and major updates to emissions standards have occurred over the years. For example, since 2014, diesel vehicles have been subject to Euro 6 regulations, and gasoline and gas-fueled vehicles have been subject to California's Non-Methane Organic Gases (NMOG) Fleet Average System (FAS). These regulations enable car manufacturers to offer a range of models with different emissions levels while ensuring that the average emissions levels are lowered over time.
South Korea's air quality has been a significant concern, with the country having the worst air quality among its peers in the Organisation for Economic Co-operation and Development (OECD) as of 2017. The average annual exposure to fine particulate matter (PM) of less than 2.5 micrometres was 25.1 micrograms per cubic metre, more than double the OECD average and above the World Health Organization's recommended air quality standard of 10 micrograms.
To improve air quality, the Korean government has announced master plans every ten years. The latest plan, released in December 2022, aims to reduce fine dust concentration by over 35% by 2030 compared to 2018 levels. These efforts demonstrate South Korea's commitment to combating air pollution from coal-fired power plants and vehicle emissions and improving the health and well-being of its citizens.

Odor pollution from Korean BBQ smoke
South Korea has been facing a pollution problem that has been deemed a "social disaster". The country's air quality was the worst among its peers in the Organisation for Economic Co-operation and Development (OECD) as of 2017. To tackle this, South Korea has implemented various measures, including mandating air purifiers in schools and removing limits on sales of vehicles with lower emissions.
One aspect of South Korea's pollution problem is odor pollution, which is a growing concern among the public. A large number of complaints have been filed regarding unpleasant smells from food waste, smoke from restaurants, and sewage. In 2016, about 25,000 Koreans lodged malodor-related complaints, with almost 30% specifically addressing sewage odors. The issue is particularly acute in low-income neighborhoods, where residents are vulnerable to odor pollution due to factors such as defective drainage pipes and illegal trash dumping.
Korean BBQ smoke is a significant contributor to odor pollution, affecting those who live near barbecue restaurants. As of 2016, 42% of restaurants in South Korea served Korean barbecue, allowing customers to cook meat on portable stoves at their tables. While the smell of barbecue may be appealing when dining out, it can be unpleasant for those trying to relax at home or engage in activities like reading. The smoke from Korean BBQ can permeate homes and leave a lingering odor on clothes and fabrics.
To address the issue of Korean BBQ smoke, Professor Song Ji-hyeon from Sejong University in Seoul has suggested making it mandatory for restaurants to install smoke and odor control devices. Professor Song also emphasized that government support should be provided to businesses that cannot afford such technology. This approach aims to prioritize the needs of those affected by smoke and malodor rather than focusing solely on the interests of restaurant owners.
The impact of Korean BBQ smoke on nearby residents highlights the broader challenge of odor pollution in South Korea. While there have been some initiatives to mitigate this issue, such as verbal warnings to restaurants, the surge in complaints indicates a need for more comprehensive and effective measures. As Kim Myung-ja, president of the Korean Federation of Science and Technology Societies, stated, actively tackling odor pollution is essential to safeguarding the quality of life for the country's citizens.

Malodor complaints about sewage
South Korea has been facing a malodor pollution problem that has been described as beyond bearable limits. The issue is particularly prominent in Seoul, where the majority of properties, including residential buildings, use septic tanks or small-scale sewage systems that treat and dispose of household wastewater on-site. This has resulted in a pervasive sewage odour that resembles rotten eggs and ammonia, impacting the lives of citizens.
The sewage odour problem in South Korea is attributed to the country's sewage system, which dates back to the colonial era in the 1920s. The system relies on on-site septic tanks, which are a major source of the odour. Hydrogen sulfide, a gas produced during the treatment of wastewater, is easily released into the atmosphere and contributes to the malodor. The problem is exacerbated during the summer months when wastewater odours intensify with higher temperatures.
To address the sewage odour issue, some have suggested that South Korea needs to transition to a different sewage system by eliminating on-site septic tanks. However, this proposal comes with significant challenges, including high costs and lengthy installation times. As a result, other measures have been considered to mitigate the problem. For instance, the country enacted the Malodor Prevention Act in 2005, mandating that large businesses, including food waste facilities, install odour-control devices. Additionally, initiatives like "Fragrant Seoul" encourage citizens to propose creative solutions, such as planting trees and flowers to absorb odours in affected areas.
While steps are being taken to address the issue, malodor complaints about sewage continue to be a concern for many residents in South Korea. The government's response to these complaints has been a topic of discussion, with some calling for more focused measures to improve the quality of life for those affected by malodor pollution.

Transboundary pollution from China
South Korea has been battling severe pollution, with air quality that is considered a "social disaster". The country has taken several measures to combat this issue, such as mandating air purifiers in schools and removing limits on the sale of liquefied petroleum gas (LPG) vehicles, which produce fewer emissions. Despite these efforts, South Korea's air pollution remains a significant concern, especially in its capital city, Seoul, which is among the world's cities with the worst air pollution.
The Korean Ministry of Environment acknowledged that long-range transboundary air pollution contributes around 30-50% of the total level of fine particles (PM2.5) in the air. Studies have shown that PM10 concentrations on the South Korean island of Baekryeong-do, located near Mainland China, increased by 44.5% when winds blew from the west or northwest. These findings highlight the significant impact of transboundary pollution on South Korea's air quality.
The issue of transboundary pollution between China and South Korea has been a subject of dispute, entangled with national political interests and diplomatic channels. Despite bilateral and multilateral efforts, there is a lack of binding agreements or policy commitments to address this environmental challenge effectively. As a result, South Korea has been exploring innovative solutions, such as creating artificial rain showers in partnership with China, to mitigate the impact of pollution on its air quality.

Seoul's poor air quality
South Korea's air quality has been a growing concern for its citizens and the international community. The country's capital, Seoul, has been at the centre of this issue, often experiencing poor air quality that affects the health and well-being of its residents.
Seoul's air pollution has gained attention due to its impact on the city's residents. Studies suggest that the poor air quality in Seoul could lead to a reduction in life expectancy for its citizens. The University of Chicago's Energy Policy Institute (EPIC) estimates that, on average, a South Korean citizen can expect to lose approximately 1.4 years of their life expectancy due to poor air quality. This issue is even more pronounced in Seoul, where residents are predicted to lose up to 1.7 years of their lives if pollution levels remain unchanged. According to the World Health Organization (WHO), air quality standards should not exceed 10 micrograms in terms of PM 2.5 levels. However, Seoul has often exceeded this recommendation, with PM 2.5 levels reaching 25 micrograms per cubic metre in 2017 and 129 micrograms per cubic metre in 2019.
The main sources of air pollution in Seoul are emissions from burning fossil fuels and vehicle emissions. The city's high population density, with approximately half of South Korea's population living in the capital, contributes to a large number of vehicles on the roads. In addition to local emissions, Seoul is also affected by pollution originating from neighbouring countries, particularly China. The combination of local and international pollution sources has led to a significant accumulation of fine dust particles in Seoul's atmosphere.
The South Korean government has recognised the severity of the problem and has implemented various measures to improve air quality in the Seoul Capital Region. In 2003, the Special Act on Seoul Metropolitan Air Quality Improvement was enacted, targeting priority pollutants such as PM10, nitrogen oxides, sulfur oxides, and volatile organic compounds. The government has also explored the use of artificial rain showers through a process called cloud seeding, where specific chemicals are released into the air to encourage the formation of water droplets that attract and wash away polluting particles. While the effectiveness of this method is still uncertain, the government remains committed to finding solutions.
The issue of air pollution in Seoul has also led to social and economic consequences. A protest group called Dust Out, comprising 44,000 female members, primarily mothers, has petitioned the government to address the health concerns for their children and future generations. Additionally, local studies have estimated the economic damage caused by air pollution, including lost production, to be about $9 billion annually, with predictions of this amount doubling by 2060.
To protect themselves from the poor air quality, Koreans often resort to wearing masks and using air purifiers. The government has also mandated the provision of air purification systems in public facilities and schools. While these short-term solutions provide some relief, more comprehensive measures are needed to address the root causes of Seoul's poor air quality.
