Which Chinese Polluters? Uncovering China's Worst Corporate Offenders

China's rapid industrialization has led to a significant increase in various forms of pollution, causing widespread environmental and health issues. The country's immense population growth since the 1980s has resulted in increased soil pollution, with an estimated 38,610 square miles of cultivated land contaminated. Air pollution, largely from coal-burning power plants and vehicles, has also led to premature deaths and health issues. In 2017, nearly 14,000 companies in China were found to have failed to meet environmental standards for controlling air pollution. This raises the question: which specific industries and companies are the worst offenders when it comes to pollution in China?

China's coal-burning power plants

China's rapid industrialization has resulted in widespread environmental and health issues. A 2015 study by Berkeley Earth, a non-profit organization, estimated that 1.6 million people in China die prematurely each year due to heart, lung, and stroke problems caused by polluted air. Another study by the Health Effects Institute found that in 2019, there were about 1.42 million premature deaths in China due to unhealthy levels of PM2.5, with an additional 363,000 deaths attributed to household air pollution from burning solid fuels.

Chinas coal-burning power plants have been identified as a significant contributor to the country's air pollution. A study published in ScienceDirect in 2020 utilized the COVID-19 outbreak as a quasi-natural experiment to analyze the impact of coal-fired power plants on air quality. The study found that during the lockdown period, when most economic activities were halted, the daily concentrations of PM2.5, SO2, and NOx remained relatively high, indicating that coal-fired power plants, which continued operating, were a major source of air pollution. This finding aligns with previous research by Liang et al. (2020) and Pan et al. (2016), underscoring the need for stricter controls and the eventual phasing out of coal-fired power plants.

China's reliance on coal as the main energy source presents logistical challenges, as nearly half of the country's rail capacity is dedicated to transporting coal to power plants, many of which are old and inefficient. The Chinese government has recognized the problem and taken steps to address it, including retiring older coal plants and investing in renewable energy sources. In 2017, China pledged to spend $367 billion on renewable power generation through 2020, but investments in clean energy fell by 8% in 2019, casting doubt on the country's commitment.

Additionally, China has continued to finance coal projects internationally, despite its 2021 pledge to phase out such financing. Through initiatives like the Belt and Road Initiative, China has provided loans and investments for coal-fired projects in other countries, even as it works to reduce its domestic coal consumption. This dichotomy between China's climate rhetoric and its actions has drawn criticism, highlighting the need for concrete steps to align with its goal of achieving net-zero carbon emissions by 2060.

While China has made efforts to reduce pollution from coal-burning power plants, the scale of the problem and the country's continued investment in coal projects, both domestically and internationally, suggest that addressing this issue will be a long-term challenge.

Mercury pollution from Chinese companies

China is currently considered the largest mercury-emitting country in the world. However, the actual mercury pollution status in China remains unknown to the rest of the world. In 1995, it was estimated that about 402 metric tons of mercury were emitted into the atmosphere from China, with the largest source being coal combustion, which includes coal-fired power plants and domestic uses, accounting for 36.1% of total anthropogenic emissions.

The province of Guizhou has received national and international attention due to its high geochemical background of mercury and the significant mercury emissions from coal combustion and mining activities. The coal in this region is often mercury-enriched, and the combustion of such coal has contributed to high levels of mercury pollution in the environment.

In addition to domestic pollution, Chinese companies have also been criticized for causing mercury pollution in other countries, such as Cameroon. Civil society groups and environmental think tanks in Cameroon have raised concerns about the pollution of rivers in the country's eastern and northern regions by gold mining companies. Specifically, two Chinese companies, Mencheng Mining and Zinquo Mining, have been accused of allowing significant amounts of mercury and cyanide to contaminate water sources, endangering the health of miners, local residents, and wildlife.

Chinese companies violating pollution rules

China has been facing alarming levels of air pollution, which has often blanketed large cities such as Beijing. The country has witnessed a rise in various forms of pollution due to industrialisation, leading to severe environmental and health issues. A 2015 study by Berkeley Earth, a non-profit organisation, estimated that 1.6 million people in China die prematurely each year from heart, lung, and stroke problems due to polluted air.

In 2017, environmental inspectors in northern China found that nearly 14,000 companies, or 70% of the businesses examined, failed to meet environmental standards for controlling air pollution. These companies operated in a range of industries, including wool processing and furniture production, and were found to be in unauthorised locations, lacking the necessary certificates, and failing to comply with emissions standards. This situation has contributed to severe air, water, and soil pollution, impacting the health and well-being of Chinese citizens.

China has not shied away from taking concrete steps to address this issue. They have retired older, less efficient coal plants and invested in renewable energy sources. In 2017, China pledged to spend RMB2.5 trillion ($367 billion) on renewable power generation, including solar, wind, hydroelectric, and nuclear energy. However, their commitment to funding renewable energies has been questioned as investments in this sector decreased by 8% in 2019 compared to the previous year.

Additionally, China has tightened its environmental regulations, implementing some of the world's toughest emissions standards. This has caught many international companies off guard, resulting in fines or even shutdown orders. While these efforts are commendable, the social and political problems caused by air pollution persist, and many Chinese citizens have expressed frustration with the public health hazard it poses.

Chinese companies with poor environmental practices

China's rapid industrialization has led to a significant increase in various forms of pollution, causing widespread environmental and health issues. The country's immense population growth since the 1980s has resulted in increased soil pollution, with an estimated 38,610 square miles (or 100,000 square kilometres) of cultivated land contaminated. This, along with air and water pollution, poses a severe threat to food safety and sustainable agriculture.

A 2015 study by the non-profit organization Berkeley Earth estimated that 1.6 million people in China die annually from heart, lung, and stroke problems due to polluted air. Another study by the Health Effects Institute found that in 2019, about 1.42 million premature deaths in China were linked to unhealthy levels of PM2.5, with an additional 363,000 deaths attributed to household air pollution from burning solid fuels.

The Chinese government has taken steps to address air pollution, particularly that stemming from coal-burning. They have invested in renewable energy sources and pledged to replace older, less efficient coal plants with more advanced facilities. However, China's investments in clean energy decreased by 8% in 2019 compared to the previous year, casting doubt on their commitment to renewable energies.

Despite these efforts, air pollution remains a significant issue, with Chinese companies often failing to meet environmental standards. In 2017, environmental inspectors in northern China found that nearly 14,000 companies, or 70% of inspected businesses, did not meet standards for controlling air pollution. These companies operated in various sectors, including wool processing and furniture production, and were found to be in unauthorized locations, lacking proper certificates, and failing to meet emissions standards.

Green groups have named and shamed some of China's biggest publicly listed polluters, including top state enterprises Sinochem International Corp and Aluminum Corp of China Ltd (Chinalco). These large state-owned firms were found to have emitted pollutants beyond national standards, indicating a failure of oversight by local authorities.

China's international trade practices have also come under scrutiny, as production for exports contributes to air pollution in other countries, including the United States. The Belt and Road Initiative (BRI), a trade network linking China with the world, has been criticized for lacking clear environmental guidelines, safety standards, and worker protections. Many BRI-funded projects fall short of international standards, resulting in negative ecological consequences for host countries.

China's impact on global air pollution

China's rapid industrialization, combined with its immense population growth, has had a significant impact on global air pollution. As the world's largest emitter of anthropogenic air pollutants, China's actions have far-reaching consequences, with its pollution reaching other countries, including the United States.

The country's industrialization has led to a rise in various forms of pollution, causing severe environmental and health issues. Notably, China's air pollution has resulted in approximately 2 million deaths per year, with ambient air pollution causing over 1 million of those deaths. The sources of this pollution are diverse, including coal combustion, biomass combustion, vehicle emissions, and industrial activities.

China's commitment to addressing global climate change through the 2015 Paris Agreement is a positive step. They pledged to peak carbon emissions by 2030 and increase the use of non-fossil fuels to 20% by the same year. In 2020, President Xi Jinping further committed to achieving carbon neutrality by 2060. However, questions remain about China's ability to meet these targets, as they must balance economic growth with social and environmental well-being.

While China has taken steps to reduce pollution, such as investing in renewable energy sources and implementing stricter emissions standards, its actions have not always aligned with its commitments. For example, China continues to expand its coal-powered electricity generation capacity, with coal consumption increasing in 2017 and 2018. Additionally, many companies in China continue to operate without meeting environmental standards, contributing to severe air, water, and soil pollution.

The impact of China's pollution extends beyond its borders. Studies have shown that a significant portion of China's emissions are associated with the production of goods for export, particularly to the United States. This means that the environmental impact of China's exports is felt globally, affecting not only China but also the importing countries.
