Air Pollution In China: Who Suffers Most?

Air pollution in China has been a significant issue for decades, causing widespread environmental and health problems. The country's rapid industrialization, population growth, and urbanization have led to increased burning of fossil fuels, resulting in smog and high levels of fine particulate matter pollution (PM2.5). This pollution has contributed to hundreds of thousands of premature deaths annually and reduced the life expectancy of Chinese citizens. While China has made substantial progress in reducing air pollution since declaring a 'war against pollution' in 2014, it still faces challenges in meeting World Health Organization (WHO) guidelines and improving overall air quality for its citizens.

Air pollution causes 350,000-500,000 premature deaths in China annually

Air pollution is a pressing issue in China, causing an estimated 350,000 to 500,000 premature deaths annually. This figure represents the devastating impact of pollution on the health of Chinese citizens, with the majority of the country's population still living in areas with poor air quality.

The main causes of air pollution in China include industrial activities, transportation, coal power plants, and the burning of fossil fuels for household energy needs. These sources release fine particles into the air, which, when inhaled, can penetrate deep into the lungs and cardiovascular system. Over time, exposure to these pollutants can lead to serious health issues, including respiratory and cardiovascular diseases, stroke, heart disease, and lung cancer.

The problem of air pollution in China has been recognised, and efforts have been made to address it. In 2014, China declared a "war against pollution", and since then, the country has made significant progress. By 2022, pollution levels had decreased by 41% compared to 2013, resulting in a potential gain in life expectancy for Chinese citizens. However, despite these improvements, air pollution remains a serious issue, with levels still exceeding the World Health Organization (WHO) guidelines.

The impact of air pollution varies across different regions of China. For example, in 2017, Tibet had the highest death rate per 100,000 population attributable to household air pollution from solid fuels, while Shanghai and Beijing had the lowest rates. Additionally, there are social inequalities in exposure to air pollution, with lower socioeconomic groups often bearing a disproportionate burden of the health risks associated with poor air quality.

To further improve air quality and reduce premature deaths, China can continue to implement measures such as increasing forest cover, improving energy efficiency, and transitioning to cleaner energy sources. Additionally, providing accessible and accurate information about air pollution risks can empower individuals to take protective actions, further reducing the health impact of air pollution.

China's air pollution has international consequences

China's air pollution has contributed to millions of premature deaths worldwide each year, with fine particles in the air causing respiratory and cardiovascular diseases. The pollution has also spread internationally, with sulfur dioxide and nitrogen oxides falling as acid rain on cities like Seoul, South Korea, and Tokyo. According to the Chinese Ministry of Health, industrial pollution has made cancer the leading cause of death in the country, and 500 million people lack access to safe and clean drinking water.

China's energy-related emissions of carbon dioxide have increased significantly, and its industries lead the world in mercury emissions, a harmful neurotoxin. The country's rapid expansion of coal-powered electricity generation and increasing consumption of coal contribute to pollution and emissions. Despite plans to reduce coal consumption, China continues to build new coal power plants, impacting the global environment and climate change efforts.

The social and economic impacts of China's air pollution are felt both domestically and internationally. Air pollution affects the quality of life and economies, with China's air pollution resulting in approximately 2 million deaths annually, including those from household air pollution caused by cooking with polluting fuels and technologies. The pollution also affects water resources, with massive algal blooms caused by high nutrient pollution, leading to marine life loss and water shortages.

China's efforts to combat air pollution have shown progress, with the country committing to peaking carbon emissions by 2030 and increasing the share of non-fossil fuels. The "War against Pollution" campaign has achieved reductions in particulate pollution, and if these improvements are sustained, China's average life expectancy could increase by 2 years. However, challenges remain, and China's leaders must balance economic growth with environmental and social welfare to address the international consequences of its air pollution effectively.

China's war on pollution is improving air quality

China's rapid industrialization, population growth, and urbanization have led to severe air pollution, causing widespread environmental and health issues. The country's war on pollution, declared in 2014, has shown significant progress, indicating a promising trajectory in improving air quality.

China's anti-pollution campaign has focused on tackling PM2.5, the most harmful type of air pollutant. Efforts to reduce PM2.5 concentrations have resulted in a 50% decline between 2013 and 2019, with further improvements during the COVID-era from 2020 to 2022. This success is attributed to stricter emissions standards for factories and power plants, as well as transitioning to cleaner fuels, which has led to substantial health benefits. According to a study, China's energy conversion has helped prevent 400,000 premature deaths annually, with residents experiencing improved air quality and visible blue skies.

The World Bank acknowledges China's progress in environmental protection, particularly in increasing forest cover and reducing air and water pollution. Lauri Myllyvirta, a lead analyst at Greenpeace, commended China's efforts, noting a 30% decrease in PM2.5 levels over five years, exceeding targets. Zou Yi, another analyst, described the annual improvements in China's air quality as "remarkable," emphasizing the positive impact on residents' health and life expectancy.

However, it is important to recognize that challenges remain. China's pollution levels still exceed the World Health Organization's guidelines, and geographical factors, such as Beijing's bowl-like shape, can exacerbate air quality issues. Additionally, there are concerns about potential backsliding, especially during winter, when unfavorable weather conditions can worsen pollution levels.

Despite these challenges, China's war on pollution is making notable strides. Sustaining and building upon these efforts is crucial to ensure continued progress in improving air quality, reducing health risks, and extending the life expectancy of China's residents.

China's pollution clean-up inadvertently caused a surge in global warming

China's rapid industrialization has resulted in an environmental crisis that has threatened the health and livelihoods of its 1.4 billion citizens and contributed to the global fight against climate change. Air pollution in China has been linked to various health issues, including respiratory and cardiovascular diseases, stroke, heart disease, lung cancer, and respiratory infections. In 2013, Beijing suffered a severe bout of smog that sparked government action and led to the announcement of a "war against pollution" in 2014.

China has made significant progress in reducing air pollution since then, with pollution levels down by 41% compared to 2013. The country has fitted scrubbers to coal power plants, tightened rules governing vehicle exhausts, and implemented policies to curb emissions, such as signing the 2015 Paris Agreement and pledging to be carbon neutral by 2060. These efforts have had a positive impact on the health of Chinese citizens, with an estimated increase in life expectancy of 2 years compared to 2013.

However, there has been an unintended consequence of China's pollution clean-up. Researchers have found that the reduction in air pollution has contributed to a surge in global warming. China's dirty air had been inadvertently cooling the planet, and by removing the pollution, the full effect of greenhouse gas-driven warming is now being observed. The analysis suggests that China's air pollution crackdown is responsible for 80% of the increased rate in global warming since 2010, contributing to an extra 0.05°C (0.09°F) per decade.

While the clean-up efforts have had a positive impact on public health in China, the consequences for the climate are significant. The warming effect was masked by the artificial cooling from pollution, and the removal of aerosols has resulted in a more pronounced warming trend. This complex interplay between pollution and climate change underscores the importance of comprehensive assessments of environmental policies and their potential global impacts.

Industrial pollution has made cancer China's leading cause of death

China's rapid industrialization has had a devastating impact on its environment, and the consequences for public health have been dire. According to the Chinese Ministry of Health, industrial pollution has made cancer the leading cause of death in the country.

The situation is particularly severe in China's cities, where high levels of air pollution cause hundreds of thousands of premature deaths each year. Fine particles in the air from the burning of fossil fuels, industry, transportation, and coal power plants can cause respiratory and cardiovascular issues, as well as lung cancer. A 2012 study found that these particles were one of the key pollutants responsible for a large fraction of damage to the health of Chinese citizens. The World Health Organization (WHO) guideline for safe levels of particulate pollution is 5 µg/m³, but China's national standard is more than seven times higher at 35 µg/m³. Despite this, China's particulate pollution average complies with its own national standard, and the country has made progress in reducing pollution levels in recent years. Since declaring a ""war against pollution" in 2014, China has reduced its fine particulate air pollution (PM2.5) by 41% compared to 2013 levels.

However, the immense urban growth of Chinese cities has led to a substantial increase in the demand for consumer goods, vehicles, and energy, which in turn has increased the burning of fossil fuels and contributed to smog. This has had a significant impact on the health of Chinese citizens. According to the World Bank, outdoor air pollution was causing 350,000 to 400,000 premature deaths annually, with an additional 300,000 deaths attributed to indoor air pollution and 60,000 to waterborne pollution. Chinese officials have asked that some of these results not be published to avoid social unrest.

The impact of industrial pollution is also evident in the emergence of so-called "cancer villages" across China. These communities, often located along polluted waterways or downstream from industrial parks, have seen an unusually high number of residents suffering from the same types of cancer. Protests have been sparked by the health fallout from pollution, and in some cases, offending industries have been closed or communities relocated. However, in many instances, contamination continues, and the government has been accused of looking the other way.
