The impact of pollution on health and the environment
China's environmental crisis, the result of decades of rapid industrialization, not only threatens the health and livelihoods of the country's 1.4 billion people but also the global fight against climate change. China's environmental problems, including outdoor and indoor air pollution, water shortages and water pollution, desertification, and soil pollution, have become more pronounced and are subjecting Chinese residents to significant health risks.
Air pollution in China contributes to an estimated 1.1 million premature deaths in China annually. A recent study in the medical journal The Lancet estimated that 1.24 million people died from exposure to air pollution in China in 2017. Since 2000, the number of people who have died from air pollution in the country tops 30 million, according to New Scientist magazine. The World Health Organization (WHO) estimated that outdoor air pollution was associated with approximately 300,000 premature deaths per year in China. Many studies have documented the adverse health effects of outdoor air pollution in China, including increases in respiratory symptoms, hospitalization, and premature mortality. Long-term exposure to pollutants can cause health risks such as respiratory diseases, cancer, cardiovascular and cerebrovascular diseases. Lead poisoning has also been described as one of the most common pediatric health problems in China, with one-third of Chinese children suffering from elevated serum lead levels.
Water pollution is another cause for serious health concern in China, especially in rural areas. Exposure to contaminated drinking water has been associated with increasing rates of digestive cancers and infectious diseases such as hepatitis and cholera. An estimated 60,000 people in China die of illnesses caused by water pollution every year.
China's environmental crisis has been driven by its carbon-intensive industries, which have caused additional environmental challenges, including water scarcity and soil contamination. China has been the world's largest annual emitter of greenhouse gases since 2006, and its emissions are increasing. Energy-related emissions of carbon dioxide in the country increased by more than 80% between 2005 and 2019. China's carbon emissions threaten global efforts to fight climate change.
The Chinese government has responded to the country's environmental crisis by implementing policies to curb emissions and address further degradation, such as signing the 2015 Paris Agreement on climate and pledging to be carbon neutral by 2060. Beijing has also taken steps to reduce air pollution by closing polluting mills, factories, and smelters and switching to other eco-friendly energy sources. Despite these efforts, China still faces significant challenges in balancing economic growth with environmental and social welfare.

The economic costs of pollution
China's rapid industrialization and economic growth have come at a cost: the country now faces immense environmental degradation and pollution. Air pollution in China has been a major source of concern since the Industrial Revolution, and it continues to pose a significant challenge to the country's social, economic, and political welfare.
One of the main contributors to the economic costs of pollution in China is the impact on public health. Air pollution leads to millions of premature deaths worldwide each year, with an estimated 1.24 million people dying from exposure to air pollution in China in 2017 alone. Long-term exposure to pollutants can cause various health risks, including respiratory diseases, cancer, and cardiovascular and cerebrovascular diseases. The social costs of these health impacts are significant, with higher rates of absenteeism in the workforce and reduced productivity. Additionally, healthcare costs for treating pollution-related illnesses can be substantial, impacting both individuals and the government.
Another economic cost of pollution in China is the impact on food production and agriculture. Water pollution, caused by industrial discharges, has contaminated China's waterways, making them largely unfit for direct human use. An estimated 6 million tonnes of food grain are contaminated by heavy metals each year, resulting in direct losses of $2.57 billion. Soil pollution, due to population growth, has also affected cultivable land, with solid waste covering or destroying vast areas. Additionally, air pollution from smog-inducing ozone and fine particles has destroyed millions of tonnes of rice, wheat, maize, and soybean crops.
Pollution has also led to social unrest and protests by Chinese citizens expressing their concerns about air quality. The Chinese government has responded with measures to improve air quality, such as reducing coal consumption and closing polluting mills, factories, and smelters. These efforts have shown some success, with a decrease in PM2.5 levels in key cities. However, balancing economic growth with environmental and social welfare remains a significant challenge for China.

The Chinese government's response to the problem
The Chinese government has implemented various measures to tackle the country's pollution problem, which has been a significant issue since the Industrial Revolution.
In 2013, the State Council issued an Action Plan for the Prevention and Control of Air Pollution, aiming to reduce PM2.5 by 10% from 2012 to 2017. The plan focused on reducing coal consumption by closing polluting mills, factories, and smelters, and transitioning to eco-friendly energy sources. As a result, there was a 23.6% decrease in PM2.5 levels in 74 key cities between 2013 and 2015, while China maintained a stable economic growth rate.
The Chinese government has also addressed lead poisoning, which was a prevalent issue among Chinese children due to pollution from metal smelters and the battery industry. In response, the government suspended battery factory production and took measures to silence criticisms. Additionally, the government has acknowledged the issue of "white pollution," primarily caused by the agricultural sector's waste management practices, and imposed bans on certain practices in the late 1990s.
To combat air pollution, the government declared a "war on air pollution" and implemented a comprehensive program with the support of the World Bank and the International Bank for Reconstruction and Development (IBRD). This program focused on energy efficiency, renewable energy, and emissions control, with a $500 million loan from IBRD leveraging additional financing for pollution control initiatives.
China has also committed to peaking carbon emissions and achieving carbon neutrality. In October 2021, the central government issued "working guidance" on its efforts to peak carbon emissions and its action plan to peak CO2 emissions before 2030. This laid the foundation for China's "1+N" climate policy system, aiming to provide direction and political guidance for decarbonization efforts.
While the Chinese government has made efforts to address pollution, challenges remain in balancing economic growth with environmental and social welfare. The country's rapid industrialization and reliance on coal have resulted in intense levels of environmental degradation, threatening global health and the economy.

The role of coal and other fossil fuels in causing pollution
China's pollution problem has been a significant issue for decades, with the country's rapid industrialization and economic growth contributing to intense levels of environmental degradation. While various forms of pollution have increased, air pollution has been a primary concern, threatening the health and welfare of Chinese citizens and the global community.
Coal and other fossil fuels have played a significant role in causing pollution in China. China is the world's largest consumer and producer of coal, and it has been a dominant component of the country's energy mix. In 2019, coal accounted for 57.7% of China's energy consumption, and the country's coal combustion has contributed more than 20% of global CO2 emissions from fossil fuels annually for the past decade. Coal-fired power generation is expected to remain a significant part of China's energy structure for the next 30 to 40 years.
The direct combustion of coal has caused severe pollution and ecological degradation, leading to increased greenhouse gas emissions. Coal production and rapid economic growth have also increased the emission of harmful pollutants such as carbon dioxide, sulfur dioxide, nitrogen oxide, and particulate matter (PM2.5 and PM10). Long-term exposure to these pollutants poses serious health risks, including respiratory diseases, cancer, and cardiovascular issues.
Large coal-powered industries, such as the steel industry, have become key drivers of China's economic development and significant contributors to air pollution. Household coal use, especially in rural areas for heating and cooking, also plays a role in air pollution, as these emissions are less filtered. China's coal-fired power stations were responsible for more than 15% of global CO2 emissions in 2020, and the country's coal production also produces methane emissions.
China has recognized the need to reduce pollution and has implemented policies to address the issue. The government has set goals to strictly control coal consumption and plans to start phasing down coal use. Efforts to develop clean coal technologies and reduce carbon emissions are also underway, with a focus on combustion and pollutant control. China's leaders are facing the challenge of balancing economic growth with environmental and social welfare.
