Air Pollution: China's Deadly Silent Killer

Air pollution is a significant issue in China, with the country leading the world in annual emissions of greenhouse gases and mercury. This has had a detrimental impact on the health of its citizens, with approximately 1 million people dying prematurely each year from air pollution, primarily due to PM2.5, PM10, and other particulate matter. The problem has been exacerbated by the Chinese Communist Party's domestic repression, which has slowed down necessary changes to reduce emissions. However, China has made notable improvements in air quality in recent years, especially during the Covid era, with a 50% decrease in PM2.5 concentrations between 2013 and 2019.

Air pollution causes 1-2 million deaths per year in China

Air pollution is a severe issue in China, causing approximately 1-2 million deaths per year. The primary sources of air pollution in China are industry, transportation, coal power plants, and household solid fuel usage. While some progress has been made to improve air quality, particularly during the Covid era from 2020 to 2022, air pollution remains a critical issue threatening public health, the economy, and people's quality of life.

According to the World Health Organization (WHO), China's air quality exceeds the safe guidelines for PM2.5 concentrations, with 81% of the population living in regions exceeding the interim target 1. This has significant health implications, as short-term and long-term exposure to PM2.5 and other pollutants increases the risk of mortality and morbidity. The health impacts of air pollution exposure include lung cancer, chronic obstructive pulmonary disease (COPD), ischemic heart disease (IHD), and stroke.

The Chinese government has recognized the severity of the problem and launched an anti-pollution campaign in 2013, targeting PM2.5 reduction. This campaign achieved a 50% decrease in PM2.5 concentrations by 2019. Additionally, the Ministry of Ecology and Environment reported that the average annual concentration of PM2.5 in 339 major Chinese cities further decreased to 29 μg/m³ in 2022. These improvements are reflected in the visible "Beijing blue" and "China blue" skies.

Despite these improvements, China still has a long way to go in its battle against air pollution. The continued destruction of the environment by the Chinese Communist Party (CCP) and the repression of press freedoms slow down the implementation of necessary changes. The disclosure of environmental data and scientific exchanges have proven to be beneficial in the past, and sustainable development policies are crucial to reducing the impact of air pollution on public health and economic development.

The air pollution crisis in China underscores the importance of access to risk-related information for residents. Providing information about air pollution risks empowers people to take preventive measures and make behavioral changes to reduce potential health risks. It is essential to address the gap between the recognition of the issue and the adoption of protective actions to further mitigate the health impacts of air pollution.

Ambient air pollution causes over 1 million deaths

Air pollution is responsible for about 2 million deaths in China annually. Of these deaths, ambient air pollution alone causes over 1 million deaths. The major contributors to air pollution in China are industry, transportation, coal power plants, and household solid fuel usage.

The harmful effects of air pollution on health are well-documented. Particulate matter (PM) pollution, especially PM2.5, has been identified as the leading cause of mortality and morbidity in China. Short-term and long-term exposure to PM2.5 increases the risk of mortality and morbidity without a discernible threshold, and can lead to premature death from lung cancer, chronic obstructive pulmonary disease (COPD), ischemic heart disease (IHD), and stroke. The magnitude of the long-term health effects of air pollution in China is comparable to that of developed countries, while the short-term impacts are relatively smaller.

The Chinese government has recognized the severity of the problem and has implemented anti-pollution campaigns to address it. The campaign launched in 2013 focused on reducing PM2.5 concentrations, which resulted in a 50% decrease in PM2.5 levels by 2019. China continued to make progress in improving air quality during the Covid era, and the average annual concentration of PM2.5 in 339 major Chinese cities fell to 29 μg/m³ in 2022.

Despite these efforts, air pollution remains a significant issue in China. In 2017, the entire population of China lived in areas with PM2.5 concentrations above the World Health Organization (WHO) Air Quality Guideline, and 81% lived in regions exceeding the WHO Interim Target 1. The high levels of air pollution have led to economic losses of over 100 billion US dollars and negatively impacted the quality of life for many Chinese citizens.

To further combat air pollution, sustainable development policies and clean air policies need to be implemented and enforced. Additionally, providing risk-related information about air pollution can empower people to take preventive measures to protect their health. Overall, China's efforts to improve air quality have shown promising results, but continued action is necessary to reduce the devastating impact of air pollution on human health and the economy.

Household air pollution causes 1 million deaths

Air pollution is a pressing issue in China, threatening the health of its citizens and the global economy. According to the World Health Organization (WHO), air pollution is responsible for about 2 million deaths in China annually. Of these deaths, ambient air pollution alone causes more than 1 million deaths, while household air pollution accounts for another 1 million. This means that household air pollution is a significant contributor to the overall death toll from air pollution in China.

Household air pollution is caused by the use of polluting fuels and technologies for cooking, heating, and lighting. In China, the proportion of the population using solid fuels for cooking has decreased significantly over the years, dropping to 32.2% in 2017 from 84.4% in 1990. However, this still translates to millions of people being exposed to harmful household air pollution.

The use of solid fuels, such as biomass (wood, animal dung, and crop waste), coal, and kerosene, for cooking and heating results in the release of particulate matter and other pollutants. These pollutants have severe health impacts, including inflammation of the airways and lungs, impaired immune response, and reduced oxygen-carrying capacity of the blood. Prolonged exposure to household air pollution increases the risk of developing non-communicable diseases, including stroke, ischaemic heart disease, chronic obstructive pulmonary disease (COPD), and lung cancer.

Women and children bear the brunt of the health impacts of household air pollution as they are typically responsible for household chores such as cooking and collecting firewood. In 2020, household air pollution was responsible for an estimated 3.2 million deaths worldwide, including over 237,000 deaths of children under the age of five. The ingestion of kerosene by accident is also the leading cause of childhood poisonings, and it contributes to a large number of severe burns and injuries in low- and middle-income countries.

To address the issue of household air pollution in China and worldwide, strong policy actions are necessary. Strategies to improve access to clean household energy include providing financial support for cleaner technologies and fuels, improving ventilation and housing design, and conducting communication campaigns to encourage the adoption of clean energy practices. By implementing these measures, the number of deaths and illnesses caused by household air pollution can be significantly reduced, improving the health and well-being of those affected.

China's emissions are increasing

China's air pollution is responsible for about 2 million deaths per year. Of those deaths, ambient air pollution causes over 1 million deaths, and household air pollution from cooking with polluting fuels and technologies causes another million deaths. Since 2000, the number of people who have died from air pollution in China exceeds 30 million.

China's air pollution is caused by industry, transportation, coal power plants, and household solid fuel usage. China is the world's leading annual emitter of greenhouse gases and mercury, and its emissions are increasing. Energy-related emissions of carbon dioxide in China have increased by more than 80% between 2005 and 2019. Overall emissions in China have been steadily increasing over the past two decades, with a sharp rise of 3.4% from 2018 to 2019.

Despite some progress in reducing emissions, China's air pollution remains at an alarming rate and affects both the Chinese population and the global economy and health. The Chinese Communist Party's destruction of the environment has been criticized for slowing down changes that could reduce emissions and benefit the environment.

To address the issue of increasing emissions, China announced its intention to peak carbon emissions by 2030 and achieve carbon neutrality by 2060. The country is exploring carbon-trading schemes and aiming for a greener power grid to reduce emissions and promote a green economic recovery.

In addition, China is making progress in reducing emissions from electric vehicles (EVs). Studies show that Chinese EVs achieve greater emissions reductions over time due to improved efficiency and a greener power grid. By 2030, transitioning to nickel-cobalt-manganese batteries and adopting a cleaner electricity mix could lead to a 53% emissions reduction throughout the entire life cycle of EVs compared to internal combustion vehicles.

Air pollution is the fourth leading risk factor for deaths in China

Air pollution is a pressing issue in China, with the country facing challenges from both ambient air pollution and household air pollution. The former has become a leading risk factor, particularly in urban areas, while the latter, though decreasing, still affects a significant portion of the population. According to the World Health Organization (WHO), air pollution is responsible for about 2 million deaths in China annually.

A study by The Lancet in 2017 revealed that air pollution was the fourth leading risk factor for deaths and disability-adjusted life-years (DALYs) in China that year. The study, which analyzed data from 1990 to 2017, found that ambient PM2.5 pollution and household burning of solid fuels were significant contributors to air pollution-related deaths. While there has been a decreasing trend in the use of solid fuels for cooking, with a significant drop from 84.4% in 1990 to 32.2% in 2017, the exposure to household air pollution remains a concern.

The health impacts of air pollution are far-reaching. Fine particles in polluted air can penetrate deep into the lungs and cardiovascular system, causing various diseases, including stroke, heart disease, lung cancer, chronic obstructive pulmonary diseases, and respiratory infections. The Western Pacific region, which includes China, bears a significant share of deaths from air pollution. The high levels of air pollution in China are attributed to various factors, including industry, transportation, coal power plants, and household solid fuel usage.

China has taken some steps to address air pollution, and there have been reductions in PM2.5 concentrations in heavily polluted areas such as Beijing. However, air pollution remains a critical issue, with the country facing the dual challenge of reducing ambient and household air pollution while also tackling economic and developmental priorities. Sustainable development policies and improved standards for monitoring air quality are crucial to mitigating the impact of air pollution on public health and the economy.
