China's Contribution To Global Air Pollution

China's air pollution has been a pressing issue for decades, threatening the health of its citizens and the global economy. As the world's leading emitter of greenhouse gases and mercury, China's rapid industrialization and energy consumption patterns have resulted in intense levels of air pollution. While China has made notable strides in reducing pollution since declaring a “war against pollution” in 2014, with pollution levels down by 41% compared to 2013, it continues to face significant challenges in mitigating the environmental, social, and economic impacts of air pollution.

China's air pollution impact on its citizens

China's air pollution has had a significant impact on its citizens, threatening both their health and economic well-being. As the world's leading annual emitter of greenhouse gases and mercury, a harmful neurotoxin, China's air pollution has resulted in numerous health issues and premature deaths among its population.

According to a study published in the medical journal The Lancet, an estimated 1.24 million people died from exposure to air pollution in China in 2017. Since 2000, the number of deaths attributed to air pollution in the country has exceeded 30 million. The high levels of air pollution, particularly from fine particulate matter (PM2.5), have been associated with various diseases, including stroke, heart disease, lung cancer, chronic obstructive pulmonary diseases, and respiratory infections. The burning of solid fuels, such as coal, in households and industries has significantly contributed to this issue.

The social and economic impacts of air pollution in China are also notable. Chinese citizens have expressed their concerns and frustrations through protests and documentaries, highlighting the negative effects of air pollution on their quality of life. Additionally, air pollution has led to significant economic costs, with estimates suggesting losses of up to $38 billion annually due to early deaths and reduced food production.

While China has made some progress in reducing pollution since declaring a "war against pollution" in 2014, the levels still exceed the World Health Organization's (WHO) guidelines. The Chinese government's commitment to achieving carbon neutrality by 2060 is a positive step, but the continued construction of coal-fired power plants and the increasing emissions raise concerns about the country's ability to meet its climate goals.

The domestic repression by the Chinese Communist Party (CCP), including limits on press freedoms, has slowed down the implementation of changes that could significantly reduce emissions and improve the environment. However, public disclosure of environmental data and collaboration with international organizations, such as the U.S. Environmental Protection Agency, have prompted China to strengthen its standards for monitoring and improving air quality.

China's air pollution impact on the world

China's air pollution has had a significant impact on both its citizens and the world. As the world's leading annual emitter of greenhouse gases and mercury since 2006, China's emissions continue to rise, with energy-related carbon dioxide emissions increasing by more than 80% between 2005 and 2019. This has resulted in serious social, economic, and political problems, as well as health issues for people worldwide.

The effects of China's air pollution are felt locally and globally. In China, air pollution contributes to approximately 2 million deaths per year, with ambient air pollution causing over 1 million deaths and household air pollution accounting for another million. According to the World Bank, outdoor air pollution alone caused 350,000 to 400,000 premature deaths annually, while indoor pollution contributed to an additional 300,000 deaths. Poor water quality also leads to 60,000 premature deaths each year in China.

China's rapid industrialization and reliance on coal as a cheap energy source have been major contributors to its air pollution. While coal consumption has decreased over the past three decades, it still accounted for 57.7% of China's energy consumption in 2019. Large coal-powered industries and power plants are key drivers of China's economic development but have severe environmental impacts. Vehicle emissions are also a significant factor, with 45% of Beijing's air pollution in 2018 attributed to this cause.

The global impact of China's air pollution is significant. Together with India, China accounts for 63.5% of world coal consumption, contributing to high levels of global air pollution. China's emissions threaten the global economy and global health, with the potential to cause millions of premature deaths worldwide each year. The destruction of the environment and disregard for air, land, and water quality by the Chinese Communist Party have drawn criticism from international leaders.

However, there are signs of improvement. China has invested significantly in reducing air pollution, and levels of harmful particulates in the air fell by 40% from 2013 to 2020. China is also the world's largest producer of electric cars, and afforestation measures are being implemented. Since declaring a ""war against pollution"" in 2014, China has made remarkable progress, with pollution levels down by 41% compared to 2013. These improvements are expected to increase the average life expectancy of Chinese citizens by 2 years.

China's air pollution sources

China's air pollution has been a pressing issue, threatening the health and economy of its people and the world. While China has made some progress in reducing pollution, it remains a significant concern. Here are some key sources of China's air pollution:

Industry and Power Plants:

China's rapid industrialization has been a major contributor to air pollution. Beijing, the capital, suffers from high levels of pollution due to its industries. Power plants, particularly coal-fired ones, are a significant source of emissions. The adoption of flue-gas desulfurization technology has helped reduce sulfur dioxide emissions, but overall emissions from power plants remain high compared to other countries due to the lack of flue gas treatment in most facilities.

Transportation:

The transportation sector is another significant source of air pollution in China. Vehicle emissions, particularly in densely populated cities like Beijing, contribute to the poor air quality.

Coal and Biomass Combustion:

Coal combustion, including for household heating and cooking, is a primary source of particulate matter emissions. The Chinese government has taken steps to reduce coal consumption by closing polluting mills, factories, and smelters, but the country is also increasing its construction of coal-fired power plants. Biomass combustion also contributes to particulate emissions.

Population Growth:

China's immense population growth since the 1980s has exacerbated pollution problems. This has led to increased soil pollution and contaminated water, threatening food safety and sustainable agriculture.

Mercury Emissions:

Beijing's industries lead the world in mercury emissions, a harmful neurotoxin. Mercury pollution poses risks to both human health and the environment.

Indoor Air Pollution:

The large-scale use of formaldehyde in constructing building products and furniture contributes to indoor air pollution, affecting the health of those who occupy these spaces.

While China has implemented measures to address air pollution, such as the "'war against pollution'" announced in 2014, it continues to face challenges in reducing emissions and improving air quality for its citizens and the global community.

China's air pollution levels over time

China's air pollution levels have been a major public health issue and have threatened the global economy and global health. The country has the highest annual emission of greenhouse gases and mercury. The air pollution in China has been caused by industry, transportation, coal power plants, and household solid fuel usage.

In 2012 and 2013, China experienced record-high air pollution, with an average Air Quality Index (AQI) of over 300 in Beijing, and readings of up to 800 at individual recording stations. This led to the Chinese government enforcing stricter regulations and publishing an Action Plan for the Prevention and Control of Air Pollution in September 2013. The plan aimed to reduce PM2.5 (fine particulate matter that is deemed the most harmful) by over 10% from 2012 to 2017.

The anti-pollution campaign resulted in a 50% reduction in average PM2.5 concentrations from 2013 to 2019. Additionally, from 2013 to 2018, the average concentration of PM2.5 and sulfur dioxide dropped by 42% and 68% respectively in the first batch of 74 cities that implemented the 2012 Environmental Air Quality Standards. The overall pollution in China fell by 10% between 2017 and 2018, and the country's air quality continued to improve during the Covid era (2020-2022).

However, in 2021, China authorized 218 GW of new coal power, and by 2023, its coal production and imports had surged, with coal's share of the energy mix returning to the 2017 level of 60%. This escalating reliance on fossil fuels has contributed to air pollution. While China's overall particulate pollution average is in compliance with its national standard of 35 µg/m³, it still exceeds the World Health Organization (WHO) guideline of 5 µg/m³.

Despite some improvements, air pollution in China remains a serious issue, and the country continues to face challenges in its battle against pollution.

China's air pollution compared to other countries

China's air pollution has been a significant cause for concern, with the country being the world's leading annual emitter of greenhouse gases and mercury since 2006. The country's rapid industrialization has led to intense levels of air pollution, threatening its citizens' health and well-being and impacting the global economy and environment. China's energy-related emissions of carbon dioxide increased by over 80% between 2005 and 2019, according to the International Energy Agency. However, it is important to note that China has also made notable progress in reducing pollution in recent years.

China's air pollution levels, particularly fine particulate matter (PM2.5), have been decreasing since the country declared a "war against pollution" in 2014. From 2013 to 2017, PM2.5 levels dropped by 33% in over 70 cities, and by 2019, Beijing recorded its lowest PM2.5 reading ever. This downward trend continued through 2022, with pollution levels down by 41% compared to 2013. As a result, the average Chinese citizen is expected to live two years longer than in 2013 if these reductions persist.

While China's overall particulate pollution average meets its national standard of 35 µg/m³, it still surpasses the World Health Organization's (WHO) guideline of 5 µg/m³. In 2019, China's cleanest city, Linzhi in Tibet, recorded a US Air Quality Index (AQI) figure of 27, while Hotan in Xinjiang Province had the worst air quality with an AQI of 179. The high levels of PM2.5 in China are primarily due to the combustion of coal, fossil fuels, and biomass, with power stations and large coal-powered industries being significant contributors.

In comparison to other countries, China's air pollution levels are among the highest globally. India, another coal-dependent country, reported that coal burning generated 46.8% of its energy consumption in 2018-2019. Together, China and India accounted for 63.5% of world coal consumption in 2019, significantly impacting global air quality. China's emissions and pollution levels also affect other countries, as noted by the U.S. Embassy in Beijing, which began monitoring the city's air quality in 2008 and prompted China to enhance its air quality standards.

To combat air pollution, China has invested heavily, pledging over $277 billion in 2013. The country is encouraging a shift from coal to natural gas and has the most electric vehicles on its roads globally. Additionally, China became the leading global source of clean energy investments in 2017 and established the world's largest carbon trading market that year. However, China's overseas energy investments during this period were largely geared towards fossil fuels, potentially locking recipient countries into high-polluting energy sources.
