The impact of economic growth
Beijing, China's capital, has been notorious for its hazardous levels of air pollution. In 2007, the New York Times published an article highlighting the severity of China's pollution problem, stating that industrial pollution has made cancer the leading cause of death in the country. China's dramatic economic growth and urbanisation, coupled with a surge in individual wealth, have contributed to a deterioration in air quality. The increase in wealth has empowered more individuals to afford motor vehicles, with the number of motor vehicles on Beijing's roads doubling to 3.3 million, and nearly 1200 added each day. Emissions from these vehicles contribute to nearly 70% of the city's air pollution.
However, Beijing has been actively combating this issue and has made significant progress in improving its air quality. The city has embraced electric mobility, with a cumulative number of 610,000 electric vehicles on the road, and has shut down polluting enterprises and rectified polluting businesses. Beijing has also implemented stricter regulations and clean air policies, such as limiting the use of coal-fired boilers and providing cleaner fuels for homes. The city's efforts have resulted in a reduction of particle pollution by more than 60% over a decade, from 2013 to 2022.
The Chinese government has played a crucial role in tackling air pollution, with the State Council issuing an Action Plan for the Prevention and Control of Air Pollution in September 2013. The plan aimed to reduce coal consumption by closing polluting mills, factories, and smelters, and transitioning to eco-friendly energy sources. Beijing also launched a four-colour alert system in 2013, based on the air quality index (AQI), to monitor and address air pollution levels.
Despite these improvements, Beijing still experiences air pollution episodes, and the levels of pollution remain above the World Health Organization's guidelines. The complex nature of the problem was further revealed during the Covid lockdowns, when a significant drop in economic activity and traffic did not lead to the expected decrease in pollution levels. This highlights the regional and global dimensions of the issue, as pollutants can be transported over long distances, affecting areas far beyond Beijing.
Overall, Beijing's efforts to improve its air quality have been commendable, and the city has made significant strides in reducing pollution levels. The combination of strict regulations, clean energy initiatives, and public health considerations has resulted in noticeable improvements. However, the challenges posed by economic growth, population increase, and industrial activities continue to impact the city's air quality, requiring ongoing efforts and innovative solutions to ensure sustainable progress.
