What You'll Learn
Industrial pollution
The effects of industrial pollution in China are evident in the degradation of aquatic and soil ecosystems. The Ministry of Environmental Protection and the Academy of Engineering of China reported that over 3 million Chinese families lack access to clean water due to water system contamination. Additionally, industrial pollution has been linked to increased cardiorespiratory and cancer mortality rates among residents. Studies have shown a correlation between exposure to air and water pollution and deteriorating health, with persistent exposure to ambient particulate matter in the air leading to higher death rates.
China has recognized the need to address industrial pollution and has implemented measures to improve its environmental record. The 13th Five-Year Plan (2016-2020) resulted in a 30% decrease in PM2.5 levels, and the country has set carbon neutrality goals. However, challenges remain, with some provinces prioritizing economic growth over environmental concerns and approving coal power plant projects.
The spatial distribution of industrial pollution in China is notable, with higher pollution indices in coastal regions that have higher industrial output values. This trend has been observed through the use of pollution emission heatmaps and indices, which track pollution intensities at the source. The clustering of polluting industries in specific regions exacerbates the environmental and health impacts on those areas.
To effectively mitigate industrial pollution, China must enforce strict and uniform pollution controls, set clear emission limits, and address the free-rider problem among polluting firms. Additionally, public disclosure of environmental data and increased press freedoms can facilitate lasting improvements in air and water quality, benefiting both China's citizens and the global community.

Greenhouse gases
China's air pollution is a pressing issue that poses significant risks to the health and well-being of its citizens and the world at large. As the world's leading emitter of greenhouse gases, China's actions and progress in addressing this issue are crucial.
In 2023, China emitted over 12.6 gigatonnes (Gt) of CO2-equivalent (CO2eq) greenhouse gases, accounting for 35% of global emissions. This figure includes emissions from coal power plants, coal mining, and blast furnaces used in iron and steel production, with coal burning alone contributing 79% of CO2 emissions. China's state coal production is responsible for 14% of historical global emissions, according to the Carbon Majors Database.
The power sector is the largest emitter of greenhouse gases in China, contributing 27% of emissions in 2020. Most electricity in China is generated from coal, which accounted for 65% of the electricity generation mix in 2019. While the percentage of coal has decreased in recent years, the construction of new coal-fired power plants is still prevalent, and coal remains the primary energy source.
China's industrial production is another significant source of greenhouse gases, emitting 1.26 Gt of GHGs in 2020. Cement and steel production are estimated to contribute 15% of emissions each, while transport and agriculture also play a role, accounting for less than 10% and 7.65% of emissions, respectively, in 2022. China's waste treatment processes also produce substantial amounts of methane, carbon dioxide, and nitrous oxide.
While China has made some progress in reducing emissions, such as surpassing its wind and solar capacity targets ahead of schedule, the country still faces challenges. The recent rebound in economic activities and fossil fuel consumption has led to an increase in emissions. Additionally, domestic repression and limits on press freedoms have slowed the implementation of changes that could positively impact the environment and reduce emissions.

Coal-fired power plants
China is the world's largest producer, consumer, and user of coal-derived electricity. In 2021, coal-fired power stations generated over half of the country's electricity.
Despite pledges to end inefficient fossil fuel subsidies in 2009, direct subsidies for coal power remained in place as of 2020. Quotas also forced utility companies to buy coal power over cheaper renewable power.
In 2024, China started construction on 94.5 gigawatts of new coal-fired power capacity, the highest level in the past 10 years. This surge in construction has been attributed to industry interests seeking to advance coal expansion under the banner of energy security.
China's push for new coal power is in direct conflict with President Xi Jinping's pledge to "strictly limit" coal consumption between 2021 and 2026 and the country's 2030 carbon-peaking action plan.
To meet its climate goals, China will need to phase out coal power without carbon capture by 2045. Strong action was taken in 2016 and 2017 by the National Energy Administration (NEA) to curb construction and cancel future coal-fired capacity. However, the retirement and mothballing of old coal plants remain low, and new coal-fired power plants continue to be built.

Population growth
China is the world's most populous country, with a population of over 1.4 billion people. This large population has contributed to the country's air pollution problem in several ways. Firstly, as the population grows, so does the demand for energy, particularly for coal-fired power plants, which are the largest contributor to CO2 emissions in the country. China is currently increasing the construction of coal-fired power plants, which will further contribute to air pollution.
Secondly, the population's transportation choices impact air quality. As more people choose to drive cars or use other fossil fuel-powered transportation, the levels of pollutants in the air increase. This is especially true in large cities like Beijing, where traffic congestion and vehicle emissions contribute significantly to the poor air quality.
Thirdly, the high population density in Chinese cities means that many people are exposed to polluted air, which can have significant health consequences. According to the World Health Organization (WHO), air pollution kills an estimated seven million people worldwide every year, with China accounting for about two million of those deaths. The fine particles in polluted air can penetrate deep into the lungs and cardiovascular system, causing various diseases, including stroke, heart disease, lung cancer, and respiratory infections.
Lastly, the population's household solid fuel usage, particularly for cooking, contributes to air pollution. In 2019, about one million deaths in China were attributed to household air pollution from cooking with polluting fuels and technologies.
Overall, China's large and growing population plays a significant role in the country's air pollution crisis, impacting the environment, the economy, and the health and quality of life of its citizens.

Soil pollution
China's rapid industrialization, population growth, and lax environmental oversight have contributed to large-scale pollution, including severe air pollution. While the Chinese government has implemented environmental policies such as the Air Pollution Prevention and Control Action Plan, soil pollution has not received the same level of attention and enforcement. This is beginning to change, with the development of environmental laws and increased government transparency.
The American embassy's independent air quality monitoring in Beijing prompted Chinese citizens to question the discrepancies between government data and the embassy's findings. This led to increased transparency and continuous air quality monitoring in all cities. Similarly, NGOs and activists have pushed for the release of data on polluted lands, resulting in the publication of a nationwide survey in 2014. This growing awareness and advocacy are now extending to soil pollution.
China is working towards addressing soil pollution through regulations under its new soil pollution control law. The polluter pays principle is a key goal, but enforcement challenges exist due to the difficulty of identifying responsible parties. To effectively tackle soil pollution, China must improve its information and science-based risk assessment of contaminants in soils. This includes defining background conditions, pollution status, relevant policies, site evaluation, and remediation strategies.
The financial commitment to soil remediation is significant, with investments reaching up to RMB 4,633,000 million (£526,000 million). As such, it is crucial that sound science and knowledge inform the decisions on how this funding is allocated to address soil pollution effectively.
