Air pollution is causing people to die 5.5 years earlier on average
Air pollution is a significant issue in China, with far-reaching consequences for public health and the environment. The burning of fossil fuels, particularly coal, has led to toxic air, causing severe health issues and reducing life expectancy. According to a 2013 study published in the Proceedings of the National Academy of Sciences, air pollution has cut 5.5 years from the average life expectancy of people in northern China. This is attributed to the increased incidence of stroke, heart disease, and cancer due to toxic air quality.
The impact of air pollution on public health in China is profound. A report by the Chinese University of Hong Kong estimated that air pollution kills approximately 1 million people annually. Additionally, a 2015 study by the non-profit organization Berkeley Earth found that 1.6 million people in China die prematurely each year from heart, lung, and stroke-related issues caused by polluted air. These figures highlight the severe consequences of air pollution on human health in the country.
The sources of air pollution in China are diverse and interconnected. The country's rapid industrialization and reliance on manufacturing and heavy industries have led to excessive emissions of greenhouse gases. Over the years, China's economic growth has been linked to increased energy consumption and physical capital expansion, contributing to air pollution. Despite recent efforts to reduce pollution, the issue remains prevalent, with over 40% of major air pollutant concentrations exceeding Chinese standards across 337 cities.
The effects of air pollution extend beyond human health, impacting the environment and agriculture as well. Contaminated water, heavy metal pollution, and solid waste have affected China's cultivable land and agricultural productivity. Approximately 38,610 square miles (100,000 square kilometres) of cultivated land have been polluted, and an estimated 6 million tonnes of food grain are contaminated by heavy metals annually. This pollution has resulted in substantial economic losses and poses a threat to food safety and sustainable agriculture, as noted by the State Environmental Protection Administration.
To address the issue of air pollution and its impact on public health, the Chinese government has implemented various measures. Beijing, for example, launched a four-colour alert system in 2013, which was revised in 2016 to standardise alert levels across multiple cities. Additionally, China has tightened targets for ozone-forming pollutants and fine particles as part of a three-year action plan aimed at improving air quality. These efforts reflect a growing recognition of the urgency to tackle air pollution and mitigate its detrimental effects on human health and the environment.

1.6 million people die each year from heart, lung and stroke problems
Air pollution in China is a significant issue, causing a range of health problems for its citizens. A 2015 study by the non-profit organisation Berkeley Earth estimated that 1.6 million people in China die each year from heart, lung, and stroke problems due to polluted air. This figure represents a significant toll on the country's population and highlights the severe consequences of air pollution.
The high number of deaths attributed to air pollution in China is a result of several factors. Firstly, China is the world's leading annual emitter of greenhouse gases and mercury, according to data from 2022. The country's rapid industrialisation and reliance on energy-inefficient and polluting industries have led to excessive emissions, with over 40% of major air pollutant concentrations exceeding Chinese standards across 337 cities. The burning of fossil fuels, particularly coal, is a significant contributor, causing people in northern China to die on average 5.5 years sooner than expected.
In addition to respiratory issues, air pollution in China has been linked to increased rates of stroke, heart disease, and cancer. The presence of heavy metals in the soil, such as mercury, lead, and cadmium, further exacerbates the problem, impacting human health through ingestion, skin contact, and respiratory intake. The elderly population in China is particularly vulnerable to the effects of air pollution, with a higher proportion of air pollution-related deaths occurring in individuals over 50 years of age.
While China has made some progress in reducing air pollution in recent years, it continues to face significant challenges. The immense population growth and urbanisation since the 1980s have contributed to soil pollution and light pollution, impacting the quality of life and health of its citizens. The Chinese government has implemented measures such as the Air Pollution Prevention and Control Action Plan in 2013, which has shown some improvements in air quality. However, the country's continued economic growth and dependence on manufacturing and heavy industries suggest that addressing air pollution will remain a complex and ongoing issue.
The social and economic costs of air pollution in China are also significant. The reduction in life expectancy and the impact on public health result in substantial losses for the country. Additionally, the environmental damage caused by pollution threatens food safety and sustainable agriculture, further underscoring the urgency of addressing this critical issue. Overall, the high number of deaths from heart, lung, and stroke problems in China due to air pollution underscores the need for sustainable development policies and effective environmental protection measures.

38,610 square miles of cultivated land are polluted
The State Environmental Protection Administration believes that pollution is a threat to the environment, food safety, and sustainable agriculture in China. A staggering 38,610 square miles (100,000 km2) of China's cultivated land has been polluted, with contaminated water being used to irrigate a further 31.5 million square miles (21,670 km2). In addition, 2 million square miles (1,300 km2) have been covered or destroyed by solid waste. This accounts for one-tenth of China's cultivable land, and the pollution is causing significant losses. Approximately 6 million tonnes of food grain are contaminated by heavy metals annually, resulting in direct losses of around 29 billion yuan (US$2.57 billion).
The presence of heavy metals, including mercury, lead, cadmium, copper, nickel, chromium, and zinc, in the soil has detrimental effects on human health. These toxic substances can enter the human body through various routes, such as ingestion, skin contact, the soil-food chain, respiratory intake, and oral intake. The impact of this land pollution on public health is severe and far-reaching.
Furthermore, air pollution in China, largely from burning fossil fuels, has led to premature deaths and a range of health issues. Studies indicate that people in northern China are dying on average 5.5 years sooner than expected due to toxic air, which has contributed to increased rates of stroke, heart disease, and cancer. An estimated 1.6 million people in China die annually from heart, lung, and stroke problems caused by polluted air, according to a 2015 study by Berkeley Earth. Other estimates, such as a study published in The Lancet, suggest that 1.24 million people died from air pollution in 2017 alone.
The Chinese Communist Party's environmental policies have been criticized for prioritizing economic growth over the health and well-being of its citizens and the planet. China has been the world's largest annual emitter of greenhouse gases since 2006, and its emissions continue to rise. While China has recently tightened targets for ozone-forming pollutants and fine particles, the impact of decades of pollution on its cultivable land and people's health is profound and will take significant time and effort to ameliorate.

China's energy consumption and emissions are increasing
China's rapid development over the past three decades has resulted in excessive emissions of greenhouse gases. The burning of fossil fuels, principally coal, has caused severe air pollution, threatening the health of Chinese citizens and contributing to environmental degradation. According to a 2012 study, China's economic growth has been dependent on energy-inefficient and polluting industries, with a reliance on manufacturing and heavy industries. This has led to an increase in energy consumption and subsequent emissions.
China's energy consumption and emissions are intricately linked to its industrialization and economic growth. While the country has made efforts to transition to renewable energy sources, its energy needs continue to be largely met by fossil fuels, particularly coal. China is the world's leading annual emitter of greenhouse gases and mercury, with its emissions showing an upward trend. Between 2005 and 2019, energy-related emissions of carbon dioxide in China surged by more than 80%.
The consequences of this pollution are dire. According to various studies and reports, the air pollution caused by these emissions is significantly impacting the life expectancy and health of China's population. A 2013 study found that severe pollution during the 1990s reduced the average life expectancy of people in northern China by 5.5 years. Another study from 2015 estimated that 1.6 million people in China die annually from heart, lung, and stroke problems attributable to polluted air. More recently, a 2017 study in The Lancet concluded that approximately 1.24 million deaths in China that year were due to air pollution exposure.
China's energy consumption and emissions have far-reaching implications beyond its borders as well. As the largest developing country in the world, China's actions have a significant impact on global health and the economy. The Chinese government has recognized the urgency of the situation and is pushing for emissions reductions and improved air quality. The transition to gas in industrial and residential sectors is one such initiative, although the young and highly efficient coal fleet remains a dominant player in energy production.
While China grapples with the challenges of reducing emissions and improving air quality, the health and well-being of its citizens continue to be at risk. The extensive pollution has led to contaminated water, soil, and food, further exacerbating the health impacts. It is imperative that China accelerates its transition to renewable energy sources and implements stringent measures to curb emissions. Only then can the country hope to reverse the trend of increasing energy consumption and emissions, safeguarding the health and future of its citizens and contributing to global sustainability efforts.
