China's Pollution Problem: Environmental Impact And Concerns

China has been notorious for being one of the world's biggest polluters, with various forms of pollution causing widespread environmental and health problems. China's industrial assets are young, averaging 10-15 years, and the country produces nearly 60% of the world's steel and cement, as well as 30% of the primary chemicals used to make plastics and fertilizers. This has resulted in high levels of air pollution, with 99.9% of China's 1.4 billion people living in areas where the annual average particulate pollution level exceeds the WHO guideline. In addition, China's waterways have been seriously contaminated by industrial discharges, making the water unsafe for human use. China has made some efforts to reduce pollution, such as implementing peak emission action plans and other climate targets, and increasing its installed renewable capacity. However, as of 2023, China continued to emit HFC-23, a super pollutant, at high levels.

Industrial pollution

China's industrial expansion since the late 1970s has contributed to record levels of air and water pollution. The country's rapid economic growth has come at a high environmental cost, with industrial firms discharging inorganic compounds and toxic gases into the water and air during production activities. This has resulted in serious water and air contamination, causing widespread environmental and health problems.

China's industrial pollution has been linked to increased cardiorespiratory and digestive cancer death rates, with the country's waterways largely unfit for direct human use. According to the World Bank, hundreds of thousands of premature deaths and incidents of serious respiratory illness have been caused by exposure to industrial air pollution in China. The Chinese Ministry of Health has also reported that industrial pollution has made cancer the leading cause of death in the country.

China's unsafe industrial processes have also made it the world's greatest emitter of mercury, a neurotoxin that poses a significant threat to public health and the environment. Additionally, China is the biggest producer and exporter of plastic products, contributing to the pollution of the environment with unmanaged plastic waste.

To tackle industrial pollution, China has implemented various measures, including the adoption of smart technologies to identify pollutants and the development of green infrastructure in cities like Beijing and Nanjing. Despite these efforts, China's overall level of air pollution remains unhealthy, affecting not only its own citizens but also downwind countries.

China's recent efforts to boost its economy by increasing industrial production have led to concerns about rising pollution levels, with several cities issuing pollution alerts. This highlights the ongoing challenge of balancing economic growth with environmental protection.

Soil pollution

China's environmental crisis, the result of decades of rapid industrialization, has had a significant impact on the country's soil. Soil pollution, in particular, has emerged as a critical issue, posing threats to both human health and the environment.

The presence of heavy metals, such as mercury, lead, cadmium, copper, nickel, chromium, and zinc, in contaminated soil, has severe health implications. These toxic substances can enter the human body through various routes, including ingestion, skin contact, respiratory intake, and oral intake, leading to adverse effects on human metabolism. China's waste production has increased, and insufficient efforts to develop effective recycling systems have been attributed to a lack of environmental awareness. This has contributed to the contamination of soil, further exacerbating the problem.

Intensive agriculture, increasing exposure to wind and rain, and the excessive use of fertilizers have led to soil erosion and depletion in China. The country's carbon content in soils is significantly lower than the world average, indicating a reduction in the concentration of organic matter. The overuse of fertilizers has resulted in soil acidification and the formation of dense, hardpan soil, impacting the fertility and health of the soil.

China's rapid industrialization has also left a legacy of polluted industrial and commercial areas. Abandoned industrial and mining sites, electronic waste sites, waste disposal sites, and agricultural land contaminated with heavy metals and agrochemicals are all sources of soil pollution. The contamination of land has not only affected the environment but also food safety and sustainable agriculture. Approximately 38,610 square miles (100,000 square kilometres) of China's cultivated land has been polluted, impacting the country's ability to produce safe and sustainable food.

To address the issue of soil pollution, China has launched initiatives such as the national soil census, which aims to update the last survey conducted 40 years ago. Additionally, the Contaminated Site Management Project, financed by a $15 million grant from the Global Environment Facility, aims to help clean up contaminated sites and improve soil pollution management. China is also focusing on protecting the health of its most fertile terrain, known as "black soil," which contributes significantly to the production of rice, soybeans, and corn.

Water pollution

The impact of water pollution on human health in China is alarming. Critical deficits in water supply and sewage treatment infrastructure have increased exposure to infectious and parasitic diseases, industrial chemicals, heavy metals, and algal toxins. In 2011, it was reported that 280 million Chinese people drank unsafe water, and a 2014 study found that heavy metals contaminated 17-20% of Chinese farmland. The lack of coordination between environmental and public health objectives, a fragmented water resource management system, and the treatment of water as a common property resource exacerbate the challenges in improving water quality and addressing health threats.

China's economic growth has come at the expense of environmental health, resulting in dangerous levels of water pollution. The country's export of environmental problems has raised international concerns. Beijing's leadership has consistently prioritized economic development, leading to poor soil health and water pollution. However, environmental degradation has become a growing political issue in China, and the government has launched efforts to reduce water pollution. In 2015, China's State Council issued the Water Pollution Prevention and Control Action Plan, setting targets for 2030. The National People's Congress also passed major revisions to the Water Pollution Prevention and Control Law in 2018, introducing a system of "river chiefs" and "lake chiefs" to hold local officials accountable for addressing specific bodies of water pollution.

Despite these efforts, water pollution remains a critical issue. In 2018, the Ministry of Ecology and Environment reported that 6.9% of surface water in China's river basins was "Below Grade V" quality, unfit for any use. The coastal manufacturing belt, including the Hai River basin and the Liao River basin, faces severe pollution. Even with the closure of thousands of pollutant sources, a third of China's waterways remain below government standards for water quality. The lack of wastewater treatment infrastructure in rural areas and poor enforcement of environmental regulations compound the problem.

Air pollution

China's carbon-intensive industries, including coal-fired power plants, have significantly contributed to air pollution. According to news reports, the country is increasing the construction of coal-fired power plants, which are the largest contributors to carbon dioxide emissions. Additionally, the total number of vehicles in China reached 360 million in 2020, making vehicle emissions a major culprit, especially in larger cities. Beijing, for example, has been plagued by heavy smog, with vehicle emissions blamed for about 45% of the city's air pollution in 2018. The confluence of topography, weather patterns, and proximity to polluting industries further exacerbates the problem in specific regions.

The health impacts of air pollution in China are severe. Epidemiological studies suggest that poor air quality in northern Chinese cities causes significant health complications, including respiratory, cardiovascular, and cerebrovascular diseases. According to the Chinese Ministry of Health, industrial pollution has made cancer the leading cause of death in the country. Various estimates indicate that hundreds of thousands of people die prematurely each year due to outdoor and indoor air pollution. A study by the Health Effects Institute found that unhealthy levels of PM2.5 led to approximately 1.42 million premature deaths in China in 2019, while another study in the medical journal The Lancet reported that 1.24 million people died from air pollution in 2017.

The Chinese government has implemented policies to address air pollution and curb emissions. Beijing, for instance, has committed to achieving carbon neutrality by 2060 and signed the 2015 Paris Agreement on climate change. However, critics argue that the government has offered few details on how it plans to achieve these goals while continuing to struggle with balancing economic growth, easing public discontent, and addressing social welfare.

Public awareness of China's poor air quality has sparked government action, and the country has made some improvements in environmental protection. The U.S. Embassy in Beijing began monitoring the city's air quality in 2008, and its data disclosure prompted China to strengthen its standards for monitoring and improving air quality. Now, U.S. embassies and consulates monitor air pollution in over 70 cities worldwide, providing real-time data through the ZephAir mobile application. Additionally, China is one of the few countries rapidly increasing its forest cover, which helps reduce air pollution.

Greenhouse gas emissions

China's greenhouse gas emissions are the highest in the world, accounting for 35% of the total as of 2023. In 2020, China emitted 12.3 billion tonnes of CO2 equivalent, amounting to 27% of global emissions. China's citizens now have carbon footprints well above the global average, and the country is home to half of the world's coal power plants. The vast majority of these CO2 emissions come from burning fossil fuels such as coal, oil, and natural gas for power generation, transportation, and industrial processes. China's agricultural sector also accounted for around 7% of its total greenhouse gas emissions in 2014, with emissions consisting mainly of methane and nitrous oxide.

China's energy sector is undergoing a transition, with a focus on electricity and a call for an "energy revolution" to combat pollution. While China has made some improvements, the overall level of air pollution remains unhealthy, and its emissions continue to affect downwind countries. China's unsafe industrial processes also make it the world's greatest emitter of mercury, a major public health threat.

In addition to its domestic emissions, China's international projects have also been criticized for their environmental impact. The Belt and Road Initiative (BRI), for example, has been accused of lacking clear environmental guidelines and has resulted in the displacement of local populations, negative impacts on water quality, and pollution of adjacent land.

China has committed to peak emissions by 2030 and net-zero by 2060. However, the country continues to build coal-fired power stations and faces challenges in integrating renewable energy sources into its existing infrastructure. Nonetheless, China is also a leader in the deployment and manufacture of low-carbon technologies, and some analyses suggest that it may overachieve its renewable energy and emission reduction goals.
