South Korea's Air Quality: A Pollution Problem?

South Korea's air quality has been a growing concern, with its fast-growing economy and increasing number of cars on the road contributing to higher emissions. The country's largest city, Seoul, has been identified as having some of the worst air pollution in the world, with levels of PM10 significantly higher than those of other capital cities. The South Korean government has implemented various measures to combat this issue, including investing in air quality management and aiming to reduce emissions from the transport sector. While there has been progress, with a noticeable reduction in air pollution in recent years, it is estimated that by 2060, air pollution will be linked to the premature deaths of 1.069 per 1 million South Koreans.

South Korea's air pollution control market

South Korea's air pollution problem has been driven by coal-fired power generation and high vehicle emissions. The country's rapid industrialization and economic growth have led to an increase in pollution, especially in large cities like Seoul, which is among the world's cities with the worst air pollution. The South Korean government has recognized the need to address this issue and has taken several measures to improve air quality and reduce emissions.

The South Korean air pollution control market was valued at $4.6 billion in 2016, accounting for 5.5% of the total environmental technology and engineering sector. The market is highly competitive and price-sensitive, with a strong focus on the sales of goods, services, and testing/analysis. The air pollution control commodity and equipment sector is the largest within this market. The US, a global leader in environmental technologies, has potential opportunities in this market, particularly through partnerships with qualified South Korean companies.

The Korean Ministry of Environment plays a crucial role in monitoring and regulating emissions under the Clean Air Conservation Act. In 2019, a revised bill introduced stricter emission standards, strengthening regulations by 30% compared to the previous version. As of 2020, South Korea enforces regulatory limits on 11 air pollutants and 32 hazardous air substances, targeting coal-fired power plants and the transport sector for emissions reduction.

To improve air quality, the Seoul, Incheon, and Gyeonggi governments invested $9 billion between 2007 and 2020, with 56% focused on transport sector emissions reduction. Efforts to retrofit power plants with carbon dioxide capture and storage (CCS) and transition to natural gas are also underway. South Korea aims to achieve carbon neutrality by 2050, embracing renewable energy sources and energy efficiency improvements.

The private sector has also contributed significantly to reducing emissions. Approximately $13.6 billion was invested by South Korean companies in NRE technologies, leading to a reduction of 11.47 million tons of GHG emissions. Additionally, a $300 billion investment program targeted the Seoul Metro system to implement improved ventilation, air conditioning, and dust-reducing measures.

The impact of air pollution on health

South Korea's air quality has been decreasing over the years, with Seoul being among the world's cities with the worst air pollution. The nation's fast-growing economy, increasing number of cars on the road, and industrial projects have contributed to the problem. The impact of air pollution on health is far-reaching, and it affects almost every organ in the body. Here are some of the key ways in which air pollution impacts health:

Respiratory System

Air pollution can cause a range of respiratory issues, including respiratory infections, aggravated asthma, and reduced lung function. Fine particulate matter, such as PM2.5, can be inhaled deeply into the lungs, causing inflammation and damage. This can lead to respiratory diseases such as chronic obstructive pulmonary disease and lung cancer. Ozone, or ground-level ozone, is a powerful lung irritant that can cause chest tightness, coughing, and shortness of breath.

Cardiovascular System

Air pollution has been linked to an increased risk of cardiovascular diseases, including heart disease and stroke. Particulate matter and pollutants such as carbon monoxide and nitrogen dioxide contribute to these issues. Long-term exposure to air pollution can also increase mortality rates due to cardiovascular illnesses.

Brain and Nervous System

Air pollution can impact the brain and nervous system, leading to neurological diseases. Fine particulate matter can enter the bloodstream through the lungs and travel to the brain, causing potential damage to brain cells and tissues. This can increase the risk of Parkinson's disease and other neurological disorders.

Immune System

Air pollution has been associated with immunosuppression, making individuals more susceptible to infections and diseases. It can also contribute to systemic inflammation, impacting multiple organ systems.

Pregnancy and Fetal Development

Pregnant women are more susceptible to the health impacts of air pollution. Exposure to air pollution during pregnancy has been linked to adverse birth outcomes, including low birth weight, pre-term birth, and congenital malformations in the circulatory, musculoskeletal, and genitourinary systems.

Other Health Effects

Air pollution has been linked to various other health issues, including eye irritation, pink eye, and increased mortality rates. It is also associated with socioeconomic factors, with people of color and economically disadvantaged communities experiencing disproportionate exposure and health impacts.

It is important to note that the health impacts of air pollution can vary depending on the types and concentrations of pollutants, as well as individual factors such as genetics, comorbidities, and sociodemographic factors.

The impact of air pollution on sports

South Korea's air quality has been declining as its economy has grown over the decades. Seoul, the nation's largest city, has the worst air pollution in the country. In 2020, the South Korean city of Jeungpyeong was ranked as the dirtiest in the country, with a US Air Quality Index (AQI) reading of 97, considered "moderate" but bordering on "unhealthy".

Large sporting events can also contribute to increased air pollution due to transportation, construction, and energy consumption. This, in turn, can harm the health of athletes, officials, and spectators. To mitigate these impacts, sports organizations make recommendations for appropriate activities based on air quality levels, using the AQI as a guide. For example, at an AQI of 100 or higher, sensitive athletes with pre-existing pulmonary or cardiac conditions should be removed from outdoor activities and monitored for respiratory impacts. At an AQI of 200 or higher, sporting authorities should consider rescheduling or moving activities indoors.

In South Korea, the decreasing air quality has impacted outdoor sports. The Korea Baseball Organization has changed its regulations to allow for the cancellation or suspension of games in the case of severe fine dust warnings. While the South Korean government has implemented policies to address air pollution, most of these focus on temporary solutions and diesel emissions reduction.

The role of China in South Korea's air pollution

South Korea has experienced high levels of air pollution in recent years. Seoul, the nation's largest city, has the worst levels of air pollution, and residents of the city will live 1.7 years less if pollution levels are not remediated. According to the U.S. Centers for Disease Control and Prevention (CDC), increasing PM2.5 air pollution has been linked to cancer, heart disease, pneumonia, and low birth weight. Long-term air pollution can lead to higher mortality rates, especially for infants and the elderly.

China plays a significant role in South Korea's air pollution due to the effects of transboundary air pollution. Prevailing wind patterns, known as "the westerlies," blow from China towards South Korea, carrying air pollutants with them. This is particularly prominent during the fall and winter months when winds from northern Chinese cities, where agricultural burning and coal-fired heating are common, move southward, increasing the levels of fine particulate matter (PM2.5) in South Korea. Research has estimated that transboundary air pollution from China accounts for approximately 19-30% of the weekly average PM10 concentrations in South Korea, with higher amounts during certain seasons.

The impact of China's air pollution on South Korea's health and economy is significant. Studies have shown that a 1 microgram per cubic meter increase in PM2.5 led to an additional 31.2 deaths for every million people annually in South Korea, with the greatest impact on infants and those with respiratory and cardiovascular diseases. There has also been an increase in emergency room visits for asthma and nasal inflammation attributed to transboundary air pollution from China. The economic cost of air pollution in South Korea, largely due to lost production, is estimated at about $9 billion a year, and this is predicted to double by 2060.

However, it is important to note that South Korea's domestic sources of air pollution, such as emissions from vehicles and power plants, also contribute significantly to the country's air quality issues. Efforts by the South Korean government to improve air quality, such as substantial investments in emissions reduction and public engagement, have shown positive results. Additionally, China's efforts to reduce air pollution through policies like its nationwide air pollution reduction program have led to a decrease in transboundary air pollution and positive health impacts in South Korea.

The impact of air pollution on the economy

South Korea's air pollution has had a significant impact on its economy, with local studies estimating the economic damage caused by air pollution, primarily due to lost production, at about $9 billion annually. This issue is projected to worsen, with predictions of the economic losses doubling by 2060. The country's heavy reliance on coal-fired power plants, diesel fuel, and fossil fuels has contributed to its air quality issues.

The economic growth of South Korea has led to an increase in various types of pollution. As the economy expanded, the country experienced a proportional rise in pollution levels. This relationship is particularly evident in the increase in fossil fuel combustion to meet the energy demands of a growing economy. The number of vehicles on the road is increasing, leading to higher vehicle emissions and contributing to the air pollution problem. Additionally, the growth in imports and exports associated with a thriving economy further exacerbates fossil fuel combustion.

The impact of air pollution on South Korea's economy is not limited to lost production. The health consequences of air pollution result in higher mortality rates and increased healthcare costs for the country. According to the U.S. Centers for Disease Control and Prevention (CDC), air pollution is linked to cancer, heart disease, pneumonia, and low birth weight. It is estimated that 16% of all deaths recorded in Seoul, the nation's largest city, are attributable to air pollution. The University of Chicago's Energy Policy Institute (EPIC) predicts that the average South Korean will lose approximately 1.4 years of life expectancy due to poor air quality.

To address the air pollution problem, the South Korean government has invested significantly in air quality management. Between 2007 and 2020, the Seoul, Incheon, and Gyeonggi governments allocated US$9 billion to improve air quality, with a focus on reducing emissions from the transport sector. This investment also included US$3.2 billion for evidence generation and public engagement on air quality. The government's efforts have resulted in a noticeable improvement in air quality in recent years, demonstrating the importance of sustained investment in addressing air pollution and climate change.

Furthermore, South Korea has recognized the importance of transitioning from fossil fuels to renewable energy sources and improving energy efficiency in transport and industry. The Five Year Action Plan promoted and created a new market for renewable energy, leading to the creation of almost 960,000 green jobs and helping the country overcome an economic crisis. This plan attracted private investments, creating a market and stimulating supply and demand for renewable energy technologies. The investments from private businesses positively impacted reducing GHG emissions by marketing green technology.
