What You'll Learn
China's pollution levels fell 42% from 2013 to 2021
China's rapid industrialization and economic growth have come at a cost: intense levels of air pollution that present serious social, economic, and political challenges. The country's heavy reliance on coal and other polluting industries have contributed significantly to this issue. However, there is good news on the horizon. China's pollution levels fell by 42% from 2013 to 2021, indicating that the country is making significant progress in its "war against pollution."
China's air pollution problem has been a pressing issue for several years. The country's rapid economic development, largely powered by coal, has resulted in immense environmental degradation. In 2013, China's Academy for Environmental Planning pledged $277 billion to combat urban air pollution, recognizing the urgency of the situation. The State Council also issued an Action Plan for the Prevention and Control of Air Pollution in 2013, aiming to reduce PM2.5 levels and coal consumption.
PM2.5, or particulate matter smaller than 2.5 micrometers in size, poses the greatest danger to human health. It can penetrate deep into the lungs and enter the bloodstream, causing various health issues. In 2012, Zhong Nanshan, the president of the China Medical Association, warned that air pollution could become China's biggest health threat. Studies have shown that air pollution contributes to millions of premature deaths worldwide each year, with unhealthy levels of PM2.5 leading to approximately 1.42 million premature deaths in China in 2019 alone.
The measures implemented by the Chinese government appear to be effective. In 2015, the average PM2.5 in 74 key cities under the monitoring system showed a 23.6% decrease compared to 2013. This decline continued, and by 2022, pollution levels were down by 41% compared to 2013. As a result, the average Chinese citizen can expect to live two years longer compared to 2013, provided these reductions are sustained.
However, despite this progress, China still faces challenges. While the country's overall particulate pollution average complies with its national standard of 35 µg/m³, it significantly exceeds the World Health Organization (WHO) guideline of 5 µg/m³. As of 2024, 99.9% of China's 1.4 billion people live in areas where annual average particulate pollution levels exceed the WHO guideline. If current pollution levels persist, China could lose 3.6 billion total life years.
China's success in reducing pollution levels demonstrates its commitment to balancing economic growth with environmental and social welfare. The country has invested significantly in renewable energy sources, pledging RMB2.5 trillion ($367 billion) in 2017 for renewable power generation. While there have been setbacks, such as a decrease in clean energy investments in 2019, the overall trend indicates that China is on the right path toward improving its air quality and the health and well-being of its citizens.

Air pollution in China
Air pollution has become a pressing issue in China, with severe consequences for the environment, public health, and political stability. The country's rapid industrialization and economic growth have come at the cost of intense levels of air pollution, which presents a series of complex challenges.
China's economic development has been heavily reliant on coal, a cheap but highly polluting energy source. While the percentage of energy consumption from coal has decreased over the past few decades, it still accounted for 57.7% in 2019. Electricity generation and large coal-powered industries, such as the steel industry, have been major contributors to air pollution. Additionally, the use of coal and solid fuels by households, especially in rural areas, significantly impacts air quality, as these emissions are less filtered.
The increase in motor vehicles has also played a significant role in China's air pollution crisis. In 2018, vehicle emissions were responsible for about 45% of Beijing's air pollution and nearly 30% in Shanghai. The concentration of exhaust from vehicles in larger cities exacerbates the problem. Topography and weather patterns further influence the distribution of air pollution, as seen in Beijing, where pollutants from nearby factories are carried by winds and trapped by surrounding mountains.
The health impacts of air pollution in China are dire. According to the World Bank, industrial air pollution has caused hundreds of thousands of premature deaths and serious respiratory illnesses. The Chinese Ministry of Health has also attributed cancer, the leading cause of death in the country, to industrial pollution. The annual Air Quality Life Index report found that China's pollution levels in 2021 had decreased by 42% compared to 2013, resulting in a 2.2-year increase in the average lifespan of Chinese citizens. However, Beijing's particulate pollution remains 40% higher than the most polluted county in the United States and exceeds the World Health Organization's guidelines.
China has recognized the urgency of addressing air pollution and has implemented measures to improve air quality. The success in Beijing, where monthly air quality has improved significantly since 2013, demonstrates that progress is possible through concerted efforts. However, challenges remain, and China continues to grapple with the delicate balance between economic growth and environmental protection.

Soil pollution in China
China's rapid industrialization and urbanization over the last few decades have resulted in immense levels of environmental degradation. While air pollution is the most pressing issue, soil pollution has also been identified as a key national priority.
Soil pollution refers to the occurrence of substances in the soil caused by human activities, which can degrade soil quality and function, damage soil structures, and harm human and environmental health. In China, soil contamination is caused by agricultural activities, urbanization, industrialization, and other human activities. Heavy metals, such as cadmium, are naturally present in soils, but elevated levels derived from these human activities can be toxic. Southern China, in particular, faces widespread exceedance of contaminant limits in food crops due to elevated inputs of contaminants, the acidic nature of the soil, and crop species that are prone to heavy metal accumulation.
China first developed its own Soil Environmental Quality Standards (SEQS) in 1995, and there are now 63 current standards related to soil environmental protection. The National Investigation Bulletin of Soil Pollution Status (NIBSPS) issued by the Ministry of Environmental Protection of the People's Republic of China (MEP-PRC) has also recognized the importance of soil pollution and degradation, committing to investing up to RMB 4,633,000 million (£526,000 million) in soil remediation.
To address soil pollution, China must identify the sources of contaminants to agricultural systems, minimize contaminant inputs, reduce heavy metal phytoavailability in soil, and select crop species that are less prone to accumulating heavy metals. Social-economic evaluation and effective enforcement of environmental protection laws are also crucial to implementing these strategies.

Water pollution in China
China's rapid industrialization and urbanization, coupled with insufficient investment in basic water supply and treatment infrastructure, have resulted in widespread water pollution. China's economic growth has been powered by coal, a cheap but highly polluting source of energy. In addition, the country's large coal-powered industries are key drivers of its economic development and have contributed to its air pollution problems.
The water pollution crisis in China has had a significant impact on the country's social, economic, and political landscape. Approximately 700 million people, over half of China's population, consume drinking water contaminated with animal and human waste. This water exceeds maximum permissible levels by up to 86% in rural areas and 28% in urban areas. The volume of wastewater produced is also alarming, with the potential for serious consequences on human health.
China's water crisis is both natural and man-made. According to estimates, 70% of China's rivers and lakes are contaminated, and half of its cities have significantly polluted groundwater. The iconic Yellow River is frequently unfit even for swimming, and experts have described the Yangtze as "cancerous." Large cities like Shanghai and Chongqing rely on these rivers for drinking water, so people across the country suffer from water pollution.
The Chinese government has addressed the pollution problem by issuing stricter regulations and investing billions in water projects. However, water quality remains poor. The country's hydraulic engineering projects, such as the Three Gorges Dam and the South-North water diversion project, aim to address water issues and generate clean energy. Still, critics argue that they may contribute to the spread of disease and negatively impact downstream water resources.
The consistent pursuit of economic growth at the expense of environmental health has led to dangerous levels of water pollution and poor soil health in China. This has become a growing political issue, and the export of these problems has incited international concern. China's unprecedented geoengineering projects and their impact on water resources have affected not only the country but also its Asian neighbors and the global environment.

China's ban on plastic bags
China's rapid industrialization and economic growth have led to intense levels of pollution, presenting serious social, economic, and political challenges. One of the key contributors to China's air pollution is electricity generation, along with large coal-powered industries, which are major drivers of its economic development. In recent years, Beijing has taken steps to address environmental issues, including a ban on single-use plastic bags and other items.
China, one of the world's biggest producers and users of plastic waste, introduced a ban on all non-degradable plastic bags in major cities, with the aim of reducing plastic waste by 30% in five years. The ban, which came into effect on January 1, 2021, prohibits restaurants from providing single-use plastic straws and stores in major cities from providing plastic shopping bags. This includes ultra-thin plastic bags less than 0.025 mm thick, agricultural mulch films, and single-use foam clamshells and plastic cotton swabs. The production and sale of these items are also banned.
The new policy was issued by the National Development and Reform Commission and the Ministry of Ecology and Environment, targeting not just stores but also postal delivery outlets, with a ban on non-degradable plastic packaging and disposable plastic woven bags by the end of 2022. The restaurant industry must reduce the use of single-use plastic items by 30%, and hotels must not offer free single-use plastic items by 2025. Markets selling fresh produce will be exempt from the ban until 2025.
This ban on plastic bags is part of China's broader efforts to tackle pollution and improve air quality. While the country's economic growth has lifted millions out of poverty, it has also resulted in immense environmental degradation. China's leaders are now facing the challenge of balancing economic growth with environmental and social welfare.
