What You'll Learn
China's carbon emissions and the global climate crisis
China's carbon emissions and environmental degradation pose a significant threat to global efforts to combat climate change. As the world's largest emitter of anthropogenic air pollutants and greenhouse gases, China's actions have far-reaching consequences. International trade has further exacerbated this issue, redistributing emissions related to the production of goods and services and altering global emission levels.
China's rapid industrialization has resulted in severe environmental problems, including air pollution, water pollution, soil contamination, and desertification. These issues not only endanger the health and livelihoods of China's vast population but also have international repercussions. A 2007 article by The New York Times highlighted how environmental degradation in China poses a political challenge to the ruling Communist Party.
The sources of China's air pollution have evolved from coal combustion to a combination of coal-fired power and motor vehicle emissions. Chemical factories and industrial sites are significant contributors, along with electronic waste, rare-earth metal mining, and pesticide use. China's growing dependence on coal power undermines its pollution control efforts and its goal to peak climate-warming emissions by 2030.
Recognizing the urgency of the situation, China has implemented various measures to address its environmental crisis. In 2019, China enacted its first comprehensive law to prevent soil pollution, imposing penalties on polluters. The country also banned the import of waste from other countries, a move that impacted Western waste exporters. Additionally, China has set targets to reduce CO2 and energy intensity levels, aligning with its previous five-year plan.
However, China's progress in combating pollution and carbon emissions remains a concern. While air quality improvements were noted during the COVID era, PM2.5 levels rebounded in 2023, falling short of WHO standards. China's hydro potential and the development of hydropower schemes have also raised concerns about seismic hazards and biodiversity loss. The risk of nuclear accidents is another emerging issue as the country expands its nuclear power infrastructure.

Air pollution and its health impacts
China's pollution problem has been well-documented, with air pollution being a particular concern. The country is the world's largest emitter of anthropogenic air pollutants, and the health impacts of this pollution are not only a domestic issue but also an international one.
Air pollution has been linked to a range of negative health outcomes, including respiratory and cardiovascular diseases, lung cancer, and stroke. Fine particles in polluted air can penetrate deep into the lungs and cardiovascular system, causing chronic obstructive pulmonary diseases and respiratory infections. The World Health Organization (WHO) has been tracking air quality and its effects on these health outcomes since 2013. According to the Chinese Ministry of Health, industrial pollution has made cancer the leading cause of death in China, with ambient air pollution alone killing hundreds of thousands of citizens each year. A 2007 report by the World Bank and SEPA estimated that up to 760,000 people die prematurely each year in China due to air and water pollution combined.
Indoor air pollution is also a significant issue, contributing to an additional 300,000 deaths in China annually. The use of coal and solid fuels by households, especially in rural areas, significantly contributes to indoor air pollution. The emissions from these sources are less filtered and can contain harmful pollutants such as SO2, NOx, CO, and BC.
The economic costs of air pollution in China are also substantial. A 2018 study estimated that $38 billion in revenue is lost each year due to early deaths and lost food production as a result of air pollution. The social impacts of air pollution have also led to protests by Chinese citizens over the poor air quality in their cities.
While China has made some progress in improving air quality, especially during the Covid era, it is premature to celebrate the end of its war against pollution. The concentration of PM2.5, the most harmful type of particulate matter, still exceeds the WHO standard, and overall PM2.5 levels rebounded in 2023 after a decade of decline.

Water pollution and contamination
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. As the world's largest source of greenhouse gas emissions, China suffers from notoriously bad air pollution. China's carbon emissions and broader environmental degradation also endanger global efforts to fight climate change, as well as economic growth, public health, and government legitimacy.
Water pollution is a serious and widespread problem in China. Decades of high economic growth driven by rapid industrialization were fuelled by a single-minded orientation to development, even at the expense of water quality. Corporations in the West were happy to outsource production to Chinese firms that paid low wages and were unconstrained by environmental controls. Local governments have often failed to crack down on polluting industries. In 2011, reports emerged that said Luliang Chemical Industry in Yunnan province had disposed of 5,000 tonnes of chemical waste next to a river used as a drinking water source. According to local residents, more than 140,000 tonnes of waste had already accumulated over 22 years. A year later, seven people, including employees and contractors of Luliang Chemical Industry, were found guilty by the Qilin District Court of Qujing of illegally discharging chromium-contaminated waste. The local government, however, took no action to regulate the company’s chemical waste disposal, and there was no monitoring system in place to track the transport of hazardous materials.
According to the Institute of Public and Environmental Affairs, a Beijing-based NGO, officials monitor the quality of surface water at 12,226 sites across the country. Of these sites, just 35% have water of good quality, another 32% are suitable for water supply, 20% are suitable for industrial or agricultural use but not for human contact, and 13% are useless. Even in Shanghai, one of China’s richest, most environmentally aware, and modern cities, 52 out of 65 monitoring sites have water not suitable for human contact. In 2015, 85% of the water in the city’s major rivers was undrinkable according to official standards, and 56.4% was unfit for any purpose.
China's water pollution problem has international repercussions. Dirty water discharges into the world's oceans, and water-borne pollutants are embedded in the food products that China exports. If polluted water cannot be used for irrigation, then Chinese agricultural production falls and global food prices rise. China has been taking steps to address this issue. In 2019, China’s first comprehensive law to prevent soil pollution took effect, requiring polluters to limit their output or pay for contamination. Two years later, China banned the import of all waste from other countries. The Thirteenth Five Year Plan in 2016 set specific goals for water consumption and water quality, aiming to reduce water consumption by 23% from 2015 levels by 2020, upgrade urban sewage facilities, and increase rates of wastewater treatment.

Soil pollution and contamination
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 is also an international concern that threatens the global fight against climate change. China's carbon emissions and broader environmental degradation endanger economic growth, public health, and government legitimacy.
Soil contamination is one of the most pressing environmental issues in China. Three decades of rapid economic development have resulted in widespread soil pollution, which has contaminated food crops and jeopardized public health. Heavy metals, nitrites, and organic pollutants in contaminated water and soil could increase the potential risk of cancers. Official estimates say that China produces 12 million tons of heavy-metal-contaminated grain annually, with an economic cost of more than $3.2 billion.
The sources of heavy metals in farmland soils include mining and smelting, sewage irrigation, sludge reuse, and fertilizer application. In 2000, a sampling survey of 3000 km2 of prime preserved cropland area found that 12.1% of the cropland had heavy metal concentrations above the acceptable standards. In 2011, it was estimated that lead, zinc, and other heavy metal pollution affected 10% of China's arable land.
China has recognized the importance of addressing soil pollution and degradation. In 2018, the country adopted its first soil pollution law, the Soil Pollution Prevention and Control Law, which holds polluters and users accountable for risk management and remediation obligations. In 2019, China's first comprehensive law to prevent soil pollution took effect, requiring polluters to limit their output or pay for contamination. While these laws demonstrate a shift towards prioritizing the environment, the challenge of financing the remediation of existing damage remains.

China's international trade and global pollution
China's environmental crisis, the result of decades of rapid industrialization, not only threatens the health and livelihoods of its 1.4 billion people but also the global fight against climate change. As the world's largest source of greenhouse gas emissions, China suffers from notoriously bad air pollution.
China's carbon emissions threaten global efforts to fight climate change. Its broader environmental degradation endangers economic growth, public health, and government legitimacy. Chemical factories and other industrial sites are mainly to blame, but trash, electronic waste, rare-earth-metal mining, overuse of pesticides, and contaminated water also contribute.
China's pollution has international repercussions. As the world's largest emitter of anthropogenic air pollutants, measurable amounts of Chinese pollution are transported via the atmosphere to other countries, including the United States. In 2006, Chinese pollution resulted in one or more extra days of non-compliance with the US ozone standard in the Los Angeles area and many regions in the eastern United States. On a daily basis, export-related Chinese pollution contributes a maximum of 12-24% of sulfate concentrations over the western United States.
International trade affects global air pollution by redistributing emissions related to the production of goods and services and potentially altering total global emissions. The US outsourcing of manufacturing to China has led to increased sulfate pollution in the western United States and decreased pollution in the east.
China has taken some steps to address its environmental issues. In 2019, China's first comprehensive law to prevent soil pollution took effect, requiring polluters to limit their output or pay for contamination. In 2021, China reported a 39% increase in performance in managing and controlling harmful and toxic chemicals.
