What You'll Learn
Air pollution in Beijing
Beijing, China's capital, has been suffering from severe air pollution. The city's economic growth, population increase, and surging number of vehicles have put immense pressure on its environment, particularly its air quality. Beijing's GDP, population, and number of vehicles sharply increased by 1078%, 74%, and 335% respectively between 1998 and 2017. As the world's largest automobile producer and consumer, China has struggled with the detrimental impacts of increased oil consumption.
Beijing's air pollution is mainly caused by high levels of coal consumption, especially during the winter heating season, and vehicle emissions. In 2013, the city's air quality deteriorated, reaching an average of 101.56 micrograms of PM2.5 particles per cubic meter. On days with severe pollution, masks became a common sight on the streets, as residents tried to protect themselves from the harmful effects of air pollution, which include increased risk of heart and respiratory diseases.
Recognizing the severity of the problem, the Beijing government published a plan to tackle air pollution in 2013. They have implemented a series of comprehensive air pollution control programs. These efforts have targeted different sources of pollution, including coal consumption and vehicle emissions. The government aims to reduce coal consumption by closing polluting mills, factories, and smelters and switching to eco-friendly energy sources. Beijing has also implemented Low Emission Zones (LEZs), which restrict access for polluting vehicles and drive the adoption of cleaner, emission-compliant modes of transportation.
In 2016, Beijing created an integrated air quality monitoring network, utilizing technologies such as high-resolution satellite remote sensing and laser radar. Over 1000 sensors were distributed across the city to precisely identify areas and times with high emissions. These dynamic strategies have helped Beijing make remarkable strides in improving its air quality in recent years, setting an example for other cities facing similar challenges.

Water pollution
The consequences of this water pollution are dire, with fish becoming extinct in more than 5% of the total river length across the country, and over 20 waterways becoming unsuitable for agricultural irrigation. The health of China's citizens is also at risk, with around 300 million people, or a quarter of the population, affected by the water crisis.
The central government has recognised the severity of the problem and has implemented stricter regulations on pollutants, investing billions of dollars in water projects. However, water quality remains poor, with a 2006 report revealing that Chongqing's tap water contained 80 out of 101 banned pollutants.
China is also undertaking massive water projects, such as the Three Gorges Dam and the South-North water diversion, to address water scarcity and flood control. However, these projects have faced criticism for their potential to contribute to the spread of disease and their impact on downstream water resources.
The country's rapid industrialization and urbanization have been major contributors to water pollution, with chemical factories, trash, electronic waste, rare-earth-metal mining, and overuse of pesticides playing a significant role. The export of these environmental problems has also incited international concern, highlighting the global impact of China's policies and the need for cooperative solutions.

Light pollution in urban areas
China's pollution is largely centred in its urban areas, with Beijing and other major cities suffering from high levels of air pollution. Light pollution in these urban areas is a significant issue, impacting both people and wildlife. The intense levels of light pollution in cities like Beijing and Shanghai are due to high-rise buildings, vast networks of streetlights, and dense concentrations of advertising billboards. This phenomenon, known as skyglow, affects astronomical observations and disrupts the natural patterns of both humans and wildlife.
Light pollution in Chinese cities has various causes and effects. One example is the impact on residential areas adjacent to brightly lit commercial streets, where unwanted light from billboards and streetlights invades homes, affecting sleep quality for residents. Another consequence is the disorientation of migratory birds, who collide with buildings due to the bright city lights. Along coastlines, artificial lighting can disrupt the spawning patterns of the Asian horseshoe crab, which relies on moonlight to guide this process.
The industrial and residential sectors in China are significant contributors to light pollution. While lighting is essential for safety, productivity, and comfort, its excessive and inefficient use leads to adverse effects. Industrial areas, with their continuous lighting needs, and residential zones, with decorative lighting, both play a role in light pollution. Economic growth and urbanisation have also contributed to the increasing brightness of China's nightscape.
To address light pollution, strategies such as adopting energy-efficient LED lighting and implementing regulations to manage outdoor lighting intensity and direction can be employed. These measures can help reduce the impact on wildlife and ecosystems, as well as contribute to carbon footprint reduction efforts in urban areas.
While light pollution is a concern, it is important to note that China faces various other environmental pollution issues. Water pollution, for instance, has affected rivers and agricultural irrigation. Air pollution, largely due to greenhouse gas emissions, poses a significant threat to public health, with high levels of PM2.5 contributing to the most severe health impacts. China has recognised these challenges and is taking steps to address them, including strengthening air quality monitoring standards and transitioning to eco-friendly energy sources.

Carbon emissions
China's environmental crisis, the result of decades of rapid industrialization, has led to the country becoming the world's largest source of greenhouse gas emissions in recent years. The country's carbon emissions threaten global efforts to fight climate change and endanger economic growth, public health, and government legitimacy. An estimated 1.24 million people died from exposure to air pollution in China in 2017, according to a study in the medical journal The Lancet.
China's carbon emissions are falling, but not fast enough. A study found that the country's carbon emissions edged down by 1% in the first six months of 2025 compared to the previous year. Lauri Myllyvirta, the lead analyst at the Centre for Research on Energy and Clean Air, stated that for China to reach its declared goal of carbon neutrality by 2060, emissions would need to fall by 3% on average over the next 35 years.
China has been installing solar panels at a rapid pace, with electricity from solar sources now surpassing hydropower and poised to surpass wind power. The country has also seen a significant increase in the use of electric vehicles and a shift towards electrification in the industrial sector, reducing carbon emissions and urban air pollution. However, China's heavy reliance on coal remains a serious concern, and the economy needs to transition to less resource-intensive sectors.
China's pollution problem is not limited to carbon emissions and air pollution. Water pollution is also a significant issue, with 19% of the main rivers in China being polluted, affecting fish populations and agricultural irrigation. Light pollution is another concern, particularly in larger urban cities and coastal areas. Chemical factories, industrial sites, trash, electronic waste, rare-earth metal mining, and pesticide overuse contribute to overall pollution levels.

Pollution in western China
China's environmental crisis, the result of decades of rapid industrialization, threatens the health and livelihoods of the country's 1.4 billion people and the global fight against climate change. The People's Republic of China is the world's leading annual emitter of greenhouse gases and mercury. This noxious air pollution threatens China's people, as well as global health and the world's economy. An estimated 1.24 million people died from exposure to air pollution in China in 2017, according to a study in The Lancet.
Pollution in China is a broad topic encompassing various forms, including air pollution, water pollution, and soil pollution, which have intensified following industrialization and rapid economic growth. While pollution is prevalent across China, there are regional variations, with some areas experiencing more severe pollution than others. Western China, in particular, has seen a recent increase in air pollution due to several factors.
Firstly, western China has witnessed a rise in energy-intensive industries, such as steel, non-ferrous metals, and coal-to-chemical processing. This shift in industrial activity towards energy-rich regions like Xinjiang and Inner Mongolia has resulted in increased emissions and air pollution levels. The long-process method of steel production, prevalent in western China due to the abundance of ores and coal, contributes significantly to this pollution.
Secondly, the burning of crop stubble in springtime to clear fields for new planting has further exacerbated air pollution in western China. This agricultural practice, combined with increased industrial output, has led to a recent upturn in pollution levels in the region. Additionally, firework displays during national festivals have also contributed to the worsening air quality.
To address the pollution problem, China has implemented initiatives such as Operation National Sword (ONS) in 2017 to monitor and regulate recyclable waste imports, banning 24 categories of solid waste and reducing the allowed contamination level for plastic waste. The country has also shown progress in improving air quality since declaring a war on pollution in 2013, with average levels of fine particulate matter (PM2.5) dropping significantly between 2014 and 2022.
