China's Air Pollution: Global Reach, Local Reasons

China's air pollution has had devastating effects on its citizens, causing an estimated 1.24 million deaths in 2017 alone, according to a study in The Lancet. The country's rapid industrialization and urbanization have led to intense levels of air pollution, threatening global health and the world economy. China's pollution has spread internationally, with sulfur dioxide and nitrogen oxides falling as acid rain on Seoul and Tokyo and even reaching Los Angeles. The country's efforts to curb air pollution have resulted in a surge in global warming, as the cooling effect of certain pollutants is no longer masking the planet's rising temperatures.

China's air pollution: a global health threat

China's air pollution is a pressing issue that not only affects its citizens but also poses a significant threat to global health and the world's economy. The country's rapid industrialization, economic growth, and population boom have led to a surge in various forms of pollution, with air pollution being particularly detrimental.

The burning of fossil fuels, especially coal, is a primary contributor to China's air pollution. Coal is the largest source of greenhouse gas emissions in China, with approximately 66% of the country's power generated from it. In 2014, China's coal usage was higher than the rest of the world combined, with an annual tonnage of 4 billion. This has severe health implications for those exposed, as fine particles from polluted air penetrate deep into the lungs and cardiovascular system, causing diseases such as stroke, heart disease, lung cancer, and respiratory infections.

The impact of China's air pollution extends beyond its borders. Pollutants like sulfur dioxide and nitrogen oxides have been carried by winds to neighboring countries like South Korea and Japan, falling as acid rain on cities like Seoul and Tokyo. According to the Journal of Geophysical Research, these pollutants have even reached the west coast of the United States. The global reach of China's air pollution underscores the urgency of addressing this issue.

China has not turned a blind eye to this problem. In recent years, the Chinese government has taken steps to address air pollution, transitioning to cleaner fuels and improving monitoring standards. Since 2013, levels of PM2.5, a dangerous microscopic particle, have been reduced significantly in many cities. By 2017, Beijing had achieved a 25% reduction in particulate air pollution, and in 2019, the city experienced its lowest PM2.5 reading to date. Additionally, over 4 million homes have switched from "dirty" fuels like coal to cleaner alternatives.

Despite these efforts, air pollution remains a critical concern. The immense urban growth and the ever-increasing number of motorized vehicles continue to exacerbate the problem. As China grapples with the challenge of balancing economic development and environmental protection, the health and economic repercussions of its air pollution persist, impacting not only its citizens but also the global community.

The war on air pollution

China's air pollution has become a pressing issue, not just for its citizens but also for the world. The country's rapid industrialization, economic boom, and population growth have led to a significant increase in various forms of pollution, threatening the environment, food safety, and sustainable agriculture. China is the world's leading annual emitter of greenhouse gases and mercury, with air pollution causing approximately 1.24 million deaths in 2017 alone.

However, the problem is far from solved. Air pollution in China remains alarmingly high, impacting the economy and people's quality of life. Major cities like Beijing continue to be shrouded in toxic air, with vehicles, power stations, and industrial emissions contributing significantly to the pollution. The health consequences are dire, with air pollution causing respiratory and cardiovascular diseases, including stroke, heart disease, and lung cancer, and respiratory infections.

Internationally, China's air pollution has spread beyond its borders. Sulfur dioxide and nitrogen oxides have fallen as acid rain on Seoul, South Korea, and Tokyo, and according to the Journal of Geophysical Research, the pollution has even reached Los Angeles in the United States. The global impact of China's air pollution underscores the urgency of the country's efforts to combat this issue.

To win the war on air pollution, China must continue to prioritize the transition to cleaner energy sources and implement stricter emission control measures. Improving air quality monitoring systems and increasing environmental oversight are also crucial steps. While the country has made notable progress, the scale and complexity of the problem demand sustained and comprehensive action. The health and well-being of people in China and beyond depend on the success of these efforts.

Air pollution reaches the US

China's air pollution is not just a problem for its citizens but also for global health and the world economy. The country is the world's leading annual emitter of greenhouse gases and mercury. The immense urban growth of Chinese cities has substantially increased the need for consumer goods, vehicles, and energy, which has, in turn, increased the burning of fossil fuels, resulting in smog.

The air pollution problem in China is caused by a combination of factors, including the enormous economic boom, a large increase in the number of motorised vehicles, population growth, increased manufacturing outputs, and natural reasons, such as topography and seasonal weather. For instance, the number of vehicles registered in Beijing is 3.3 million, and this figure increases by 1,200 each day. Vehicle emissions contribute to almost 70% of Beijing's polluted air. The most dangerous pollutants include PM2.5, sulphur dioxide (SO2), nitrogen dioxide (NO2), and carbon monoxide (CO).

The health consequences of air pollution are severe. In 2017, an estimated 1.24 million people died from exposure to air pollution in China, according to a study in the medical journal The Lancet. Since 2000, the number of people who have died from air pollution in the country tops 30 million, according to New Scientist magazine. Air pollution has also led to school closures, agricultural complications, and the shuttering of major attractions.

The impact of China's air pollution has spread internationally. According to the Journal of Geophysical Research, the pollution reaches as far as Los Angeles in the US. The US Embassy in Beijing has been monitoring the city's air quality since 2008, and its public disclosure of data has prompted China to strengthen its standards for monitoring and improving air quality. Now, US embassies and consulates are monitoring air pollution in over 70 cities worldwide and disseminating real-time air quality data through the ZephAir mobile application. This app allows citizens around the world to protect themselves from air pollution, a leading cause of death.

Beijing's air quality crisis

Beijing, China's capital city, has long suffered from a severe air quality crisis. On the evening of 11 January 2013, Beijing was enveloped in a thick dark cloud of smog, with air pollution levels 22 times higher than World Health Organization guidelines. The crisis is driven by heavy industry growth, lax environmental regulation, and an energy-intensive economic growth model reliant on infrastructure and fixed asset investment. The burning of fossil fuels and rapid urbanisation have also contributed to Beijing's poor air quality, leading to respiratory and cardiovascular issues among residents.

The Chinese government has recognised the severity of the problem, with the State Council announcing a RMB 1.7 trillion plan in 2013 to address the nation's chronic air pollution crisis. This plan, the "2013-2017 Air Pollution Prevention Action Plan", aimed to tackle the issue through inter-ministerial coordination between China's top economic, energy, and environmental agencies.

Despite some progress, air pollution remains a significant concern in Beijing. Real-time air pollution maps and phone apps provide residents with access to air quality information, highlighting the ongoing public health crisis. The availability of such data has increased awareness among the public and authorities, with air pollution contributing to approximately 2 million deaths annually in China.

The crisis has also had international implications, with pollution spreading beyond China's borders. Cities like Seoul, Tokyo, and Los Angeles have experienced the effects of Beijing's air pollution, underscoring the global impact of local environmental issues. Beijing's air quality crisis serves as a stark reminder of the urgent need for sustainable practices and effective pollution control measures to protect public health and the environment.
