China’s Air Pollution: A Decades-Long Battle for Cleaner Skies
Beijing Breathes Easier, But China’s Air Quality Battle Continues
Beijing is experiencing a noticeable improvement in air quality, a transformation driven by years of concerted effort from the Chinese government. What was once a city shrouded in smog is now seeing families enjoying parks and retirees practicing gymnastics outdoors. However, the fight against pollution is far from over, and challenges remain across the country.
From ‘Airpocalypse’ to Gradual Improvement
Fifteen years ago, Beijing was often choked by severe smog. Zhao, 83, recalls a time when the pollution was so bad she wouldn’t venture outside. Today, she finds the air “very good.” This shift reflects a significant policy push to tackle pollution, initially spurred by public concern and highlighted by foreign data.
Between 2014 and the end of 2023, particulate matter (PM2.5) levels nationally decreased by 41%. This improvement has had a tangible impact on public health, with average life expectancy increasing by 1.8 years, according to the Air Quality Life Index (AQLI) from the University of Chicago.
Early Measures and the 2008 Olympics
China’s initial efforts to improve air quality included the installation of desulfurization technologies in power plants, temporary factory closures, and traffic controls. These measures brought temporary improvements, notably during the 2008 Olympic Games.
However, the situation deteriorated as public awareness grew, fueled by the publication of foreign data. This led to the Communist Party of China publishing a ten-point action plan, declaring “war on pollution.”
A “Miracle” Achieved Through Strong Policy
The approach involved enhanced monitoring, relocation or closure of coal plants and mines, reduced vehicle traffic, and laying the groundwork for widespread electrification in major cities. According to Tonny Xie, director of the Bluetech Clean Air Alliance, “I think everyone will agree that China has accomplished a real miracle.”
The AQLI attributes the global decline in pollution since 2014 “entirely” to China’s progress.
Persistent Challenges and Regional Variations
Despite the overall improvement, challenges persist. Cities like Shanghai still regularly appeared among the 20 most polluted globally as of winter 2025. Even with progress, the current Chinese definition of “good” air quality (35 micrograms per cubic metre of PM2.5) is significantly higher than the World Health Organization’s recommendation of 5 micrograms per cubic metre.
Linda Li, a running coach who has lived in both Beijing and Shanghai, notes that pollution still disrupts training schedules, requiring 5-7 days of cancellation per month.
Shifting Pollution and the Rise of Renewables
Recent research suggests that pollution is now shifting westward as heavy industry relocates to regions like Xinjiang. Chengcheng Qiu, from the centre for Research on Energy and Clean Air (CREA), explains that “the easiest solutions to implement” have already been deployed.
However, there is reason for optimism. China is becoming a major power in renewable energy, and data shows a nearly 2% decrease in power generation from coal-fired plants in 2025, despite overall demand increasing.
The Path Forward: A Transition to Clean Energy
The future of air quality in China hinges on a continued transition away from fossil fuels. Chengcheng Qiu emphasizes, “there is only one clear path to cleaner air: abandoning fossil fuels and letting clean energy become the engine of the next stage of development.”
China aims to reduce its PM2.5 concentration from 35 to 25 micrograms per cubic metre by 2035, signaling a continued commitment to improving air quality.
FAQ
Q: Has Beijing’s air quality really improved?
A: Yes, significantly. PM2.5 levels have decreased by 41% nationally between 2014 and 2023, and life expectancy has increased.
Q: What steps did China take to improve air quality?
A: Measures included installing pollution control technologies, closing factories, restricting traffic, and investing in renewable energy.
Q: Is the air quality in China now considered “good”?
A: While improved, China’s definition of “good” air quality is still more lenient than the World Health Organization’s standards.
Q: What are the remaining challenges?
A: Pollution is shifting to other regions, and a complete transition away from fossil fuels is still needed.
Did you know? The improvement in air quality in China has contributed to a global decline in pollution levels since 2014.
Pro Tip: If you are travelling to China, check the air quality index (AQI) for your destination and consider wearing a mask during periods of high pollution.
