What You'll Learn
China's air pollution problem
The problem has been exacerbated by industrialization, population growth, and the use of polluting fuels and technologies. Various forms of pollution, including air, soil, and water pollution, have had widespread environmental, health, and economic impacts. The contamination of China's waterways by industrial discharges has rendered many unfit for direct human use, and soil pollution, caused partly by the use of contaminated water for irrigation, has affected cultivable land.
The Chinese government has acknowledged the severity of the issue and taken steps to address it. In 2013, the government published a plan to tackle air pollution, aiming to reduce coal consumption and switch to eco-friendly energy sources. This campaign resulted in a 50% decrease in PM2.5 concentrations by 2019 and continued improvements during the COVID-era from 2020 to 2022.
Despite these efforts, air pollution remains a pressing concern. It is responsible for about 2 million deaths in China annually, causing diseases such as stroke, heart disease, lung cancer, and respiratory infections. The problem is particularly acute in major cities like Beijing, where residents often have to cope with heavy smog.
To combat this, the Beijing government has implemented temporary measures, such as shutting down industrial facilities and reducing car emissions ahead of significant events. However, there is a need for long-term, comprehensive strategies that address multiple pollutants simultaneously to effectively tackle China's air pollution crisis.

The impact of pollution on health
China's rapid economic and social development has resulted in severe air pollution, which has had adverse impacts on society and public health. Air pollution is responsible for about 2 million deaths in China per year. Of these deaths, ambient air pollution alone caused more than 1 million deaths, while household air pollution from cooking with polluting fuels and technologies caused another million deaths in the same period. According to a recent study in the medical journal The Lancet, an estimated 1.24 million people died from exposure to air pollution in 2017. Since 2000, the number of people who have died from air pollution in China tops 30 million, according to New Scientist magazine.
Air pollution leads people to be exposed to fine particles in polluted air that penetrate deep into the lungs and cardiovascular system, causing diseases including stroke, heart disease, lung cancer, chronic obstructive pulmonary diseases, and respiratory infections. China's capital, Beijing, suffers from high levels of air pollution. The Chinese government published a plan to tackle the air pollution problem in 2013. The main goal of the plan was to reduce coal consumption by closing polluting mills, factories, and smelters, and switching to other eco-friendly energy sources. These policies have been taking effect, and in 2015, the average PM2.5 in 74 key cities under the monitoring system was 55 μg/m3, showing a 23.6% decrease as of 2013.
In addition to air pollution, China also faces significant soil pollution and water pollution issues. 38,610 square miles (100,000 km2) of China's cultivated land have been polluted, with contaminated water being used to irrigate a further 31.5 million square miles (21,670 km2). An estimated 6 million tonnes of food grain are contaminated by heavy metals every year, causing direct losses of 29 billion yuan (US$2.57 billion). The agricultural sector is a particularly significant source of waste, with Chinese farms generating more pollution than factories.
Overall, pollution has had a significant impact on the health of people in China, leading to various diseases and premature deaths. The Chinese government has taken some steps to address the issue, but air pollution remains at an alarming rate and continues to affect the economies and people's quality of life.

The trade-off between economic growth and environmental protection
China's rapid economic growth has lifted millions of people out of poverty, but it has also led to immense environmental degradation. The country's economic development has been largely dependent on industrialization, urbanization, and motorization, all of which have significantly contributed to the pollution problem.
China's growth has been heavily reliant on coal, a cheap but highly polluting source of energy. While the percentage of energy consumption from coal has decreased over the years, it still accounted for 57.7% in 2019. As a result, China is the world's leading annual emitter of greenhouse gases and mercury. The country's air pollution has been linked to millions of premature deaths, with an estimated 1.24 million people dying from exposure to it in 2017 alone.
Recognizing the severity of the issue, the Chinese government has implemented various measures to tackle air pollution. In 2013, the government published a plan to reduce coal consumption by shutting down polluting mills, factories, and smelters, and transitioning to eco-friendly energy sources. This resulted in a 23.6% decrease in PM2.5 levels in 74 key cities between 2013 and 2015, while also maintaining a stable economic growth rate. In 2014, China announced a "war against pollution," which has shown remarkable progress, with a 41% decrease in fine particulate air pollution (PM2.5) between 2013 and 2022.
However, challenges remain. China's overall particulate pollution average complies with its national standard, but it still exceeds the World Health Organization (WHO) guideline. Additionally, the trade-offs between environmental protection and economic growth present a complex dilemma, especially for developing countries like China. The country's steel industry, a key driver of economic development, became the biggest polluter in 2017, surpassing electricity generation. Moreover, the agricultural sector, with its heavy use of plastic and electronic waste, also contributes significantly to pollution.
Balancing economic growth and environmental protection is a delicate task. While China has made notable strides in reducing pollution, sustaining these improvements and meeting international standards will be crucial in the coming years to ensure the health and well-being of its citizens and the world.

China's war on pollution
Industrialization and Economic Growth
China's economic development has been powered significantly by coal, a cheap but highly polluting energy source. While coal consumption has reduced over the years, it still accounted for 57.7% of the country's energy usage in 2019. The large coal-powered industries are major contributors to China's air pollution, and the steel industry became the biggest polluter by 2017.
Air Pollution and Health Impact
Air pollution in China has led to alarming health consequences. Fine particles in the polluted air penetrate the lungs and cardiovascular system, causing diseases such as stroke, heart disease, lung cancer, and respiratory infections. According to the World Health Organization (WHO), air pollution kills an estimated seven million people worldwide annually, with China experiencing about two million deaths per year due to air pollution.
Policy Initiatives and Interventions
China has implemented various measures to tackle air pollution. In 2013, the Chinese government published a plan to reduce coal consumption by shutting down polluting mills, factories, and smelters, transitioning to eco-friendlier energy sources. As a result, there was a 23.6% decrease in PM2.5 levels in 74 key cities between 2013 and 2015. In 2014, China announced a "war against pollution," and by 2022, pollution levels had decreased by 41% compared to 2013.
Plastic Waste and Agriculture
China has also addressed plastic waste, coining the term "white pollution" to describe the proliferation of white plastic bags, Styrofoam containers, and light-colored materials in the environment. In 2008, a ban was imposed on providing free plastic bags in supermarkets and shops, encouraging the use of cloth bags. This led to a 10% reduction in plastic bags in the garbage the following year. However, the agricultural sector, including Chinese farms, remains a significant source of pollution, generating more waste than factories.
International Cooperation
International cooperation has played a role in China's war on pollution. The U.S. Embassy in Beijing began monitoring the city's air quality in 2008, leading to improved air quality standards in China. The U.S. Department of State also launched the ZephAir mobile application, providing real-time air quality data to citizens worldwide.
In summary, China's war on pollution has shown progress, with decreasing pollution levels and improvements in life expectancy. However, challenges remain, especially in balancing economic growth with environmental and social welfare. China continues to grapple with the trade-offs between economic development and environmental protection, highlighting the complexities of addressing pollution in a developing country.

The role of the US in monitoring China's air quality
China has long suffered from high levels of air pollution, which has threatened the health of its citizens and the economy. In 2008, the US Embassy in Beijing began monitoring the city's air quality and publicly disclosing the data. This prompted China to strengthen its standards for monitoring air quality and improve it. The US Embassy's actions also encouraged scientific exchanges with the US Environmental Protection Agency.
The US State Department has also played a pivotal role in raising awareness and spurring policy change in China. The independent data source allowed citizens, media, and environmental groups to hold authorities accountable and ensured that the reported improvements were genuine. The US State Department's decision to cease sharing data from regulatory-grade air quality monitors at embassies and consulates worldwide is a significant loss for China. This is because, in China, it is illegal to publicly share air quality data from non-government monitors.
The US embassies and consulates are now monitoring air pollution in more than 70 cities worldwide and disseminating air-quality data in real-time through ZephAir, a mobile application recently launched by the US Department of State. This app provides reliable information about air quality and allows citizens to protect themselves from air pollution.
