China's air pollution crisis
Coal production and consumption have released harmful pollutants such as carbon dioxide, sulfur dioxide, nitrogen oxide, and fine particulate matter (PM2.5 and PM10). According to the World Health Organization (WHO), China's fine particulate air pollution (PM2.5) levels still exceed the recommended guideline of 5 µg/m³, despite overall compliance with the national standard of 35 µg/m³. This discrepancy has severe health consequences, with ambient air pollution causing hundreds of thousands of premature deaths annually, primarily from respiratory and cardiovascular diseases.
The Chinese government has acknowledged the severity of the problem and launched anti-pollution campaigns, notably the “war against pollution" declared in 2014. These efforts have shown promising results, with a 41% decrease in pollution levels between 2013 and 2022. The average PM2.5 concentration dropped by 50% from 2013 to 2019, and blue skies have returned to Chinese cities. The country now boasts the fastest air quality improvement worldwide.
However, challenges remain. China's rapid economic growth and motorization have led to a significant increase in vehicles, which are major contributors to air pollution, especially in larger cities. Additionally, the country faces issues with soil pollution, water pollution, and solid waste management. Desertification affects 1,740,000 square kilometers of land, impacting the lives of 400 million people and causing economic losses.
Addressing China's air pollution crisis requires a sustained commitment to implementing effective policies and strategies. While progress has been made, continued efforts are necessary to ensure that economic development is balanced with environmental protection and the well-being of China's population.

Water scarcity and soil contamination
China is the world's biggest water user, accounting for 13% of the world's freshwater consumption. In a country experiencing rapid urbanization and economic development, clean water is becoming scarcer. Aquifer levels are dropping, lakes are disappearing, rivers are drying up or becoming polluted, and air contaminants are producing acid rain.
A long-term study by the Ministry of Land and Resources and the Ministry of Ecology and Environment in 2014 found that heavy metals contaminated 17% of Chinese farmland. A later estimate put these estimates at about 20% of available land, and noted that a quarter of China's arable land is "becoming desert" due to water and soil pollution and overuse. Once soil becomes so damaged, it requires remediation over multiple generations to reverse the process.
According to estimates, 70% of China's rivers and lakes are currently contaminated, and half of China's cities have significantly polluted groundwater. This has had serious health consequences, with about 300 million people in China drinking contaminated water every day. Almost two-thirds of these people, 190 million, fall ill. More than 30,000 children die each year from diarrhea caused by contaminated water, and China's water has been blamed for high rates of cancer, stunted growth, low IQs, miscarriages, and birth defects.
China's water scarcity is exacerbated by pollution, with inadequate water quality contributing to regional inequality. Water scarcity is a widespread problem in many parts of the world, occurring when the demand for freshwater exceeds the available supply. This is particularly true in China, where per capita available water resources amount to only one-fourth of the world average.
China is undertaking a massive water project called the South-North Water Diversion, which intends to engineer three new waterways to carry water from China's wet south to its dry north. This project began in 2002 and is projected to cost $60 billion. More than 200,000 people will be relocated, and the relocations are likely to encourage people to destroy forests for new land, accelerating soil erosion.

Health and economic impacts
China's air pollution has had a significant impact on the health of its citizens, as well as the global population. In 2017, an estimated 1.24 million people died from exposure to air pollution in China, according to a study in The Lancet. Since 2000, over 30 million people have died from air pollution in the country, according to New Scientist magazine. The Chinese Ministry of Health has declared that industrial pollution has made cancer the leading cause of death in the country.
Long-term exposure to pollutants can cause various health issues, including respiratory diseases, cardiovascular and cerebrovascular diseases, and cancer. In 2013, Beijing recorded dangerously high levels of PM2.5 (particulate matter smaller than 2.5 micrometers), which had severe health impacts on residents, especially during the colder seasons. The increasing number of air pollutants has also led to incidents of low visibility and acid rain, which can have further health repercussions.
The economic consequences of China's air pollution are also significant. The country's rapid economic growth, driven largely by coal, has resulted in immense environmental degradation. Coal production has increased the emission of harmful pollutants such as carbon dioxide, sulfur dioxide, and nitrogen oxide. While coal consumption has decreased over the years, it still accounted for 57.7% of China's energy consumption in 2019. The steel industry has also become a major contributor to air pollution, surpassing electricity generation as the biggest polluter by 2017.
China's air pollution has also impacted other sectors, such as transportation. With over 360 million vehicles on the road in 2020, vehicle emissions have become a significant source of pollution, particularly in larger cities. Additionally, desertification has disrupted the lives of 400 million people and caused economic losses of 54 billion yuan ($7 billion) annually.
The Chinese government has implemented measures to improve air quality, but balancing economic growth with environmental and social welfare remains a challenge. Environmental regulations and industrial reforms have had some positive effects, and continued efforts are likely to further reduce pollution levels. However, the country's economic development is closely tied to industrialization, urbanization, and motorization, which are significant contributors to pollution.

The role of coal and industrialization
China's rapid industrialization has led to severe air pollution, causing significant social, economic, and political issues. The country's economic growth has been largely powered by coal, a cheap but highly polluting energy source. Coal combustion accounts for 70% of China's total energy consumption and is a major contributor to air pollution.
Coal production has increased the emission of harmful pollutants such as carbon dioxide, sulfur dioxide, nitrogen oxide, and fine particulate matter (PM2.5 and PM10). Long-term exposure to these pollutants poses serious health risks, including respiratory diseases, cancer, and cardiovascular issues. China's industrialization has also resulted in soil pollution, with 100,000 square kilometers of cultivated land contaminated, impacting food safety and sustainable agriculture.
To address these issues, the Chinese government has implemented policies aimed at reducing coal consumption and improving air quality. During the 13th Five-Year Plan (2016-2020), measures such as capping coal use, removing dispersed coal from urban areas, and tightening CO2 emissions standards were introduced. In 2020, President Xi Jinping pledged to achieve carbon neutrality by 2060, emphasizing decarbonization as a policy goal.
While China has made progress in reducing pollution, challenges remain. Coal consumption increased in 2021, highlighting the economy's continued dependence on coal. China's industrialization and massive population growth have exacerbated pollution levels, with vehicles also contributing significantly to air pollution, particularly in larger cities.
The trade-offs between environmental protection and economic growth present a complex situation for China. As industrialization and urbanization drive economic development, they also contribute to the country's pollution crisis. China's leaders must navigate the delicate balance between economic growth and environmental sustainability to address the pressing pollution issues the country currently faces.

Pollution control efforts and challenges
China's pollution problem is a result of its rapid industrialization and population growth, which has led to intense levels of air, water, and soil pollution. The country's economic growth has been powered by cheap and abundant fossil fuels, particularly coal, which has resulted in high emissions of harmful pollutants such as carbon dioxide, sulfur dioxide, nitrogen oxide, and fine particulate matter (PM2.5 and PM10). Long-term exposure to these pollutants has severe health impacts, including respiratory diseases, cancer, and cardiovascular issues.
Recognizing the severity of the problem, the Chinese government has implemented various measures to control and reduce pollution. In 2014, China announced a "war against pollution," which has led to a decline in fine particulate air pollution (PM2.5) through the implementation of stricter regulations and action plans. The government has also invested significantly in combating pollution, with China's Academy for Environmental Planning pledging $277 billion to combat urban air pollution in 2013. Additionally, China has addressed financing challenges for renewable energy projects and improved energy efficiency in the industrial and building sectors.
To reduce the use of fossil fuels, China has focused on transitioning to clean energy sources. This includes installing equipment to remove particulate matter, flue gas desulfurization, and denitrification, as well as expanding the use of clean energy vehicles. China has also received support from international organizations such as the World Bank and the International Bank for Reconstruction and Development (IBRD), which have provided financing and loans to support the government's air pollution control programs.
Despite these efforts, China still faces significant challenges in balancing economic growth with environmental and social welfare. Population growth has resulted in increased soil pollution, with contaminated water being used for irrigation and solid waste covering cultivable land. The agricultural sector is a significant source of pollution, and desertification affects the lives of 400 million people, causing economic losses of $7 billion annually. Additionally, the total number of vehicles in China reached 360 million in 2020, making vehicle emissions a major contributor to air pollution, especially in larger cities.
While China has made progress in reducing pollution, particularly in terms of decreasing PM2.5 concentrations, the country still has a long way to go to meet the World Health Organization's (WHO) guideline of 5 µg/m³ for fine particulate pollution. If current pollution levels persist, China could lose 3.6 billion total life years, and an average resident's life expectancy is shortened by 2.3 years relative to the WHO guideline.
