Xi'an's air pollution is linked to respiratory mortality
Xi'an, China, is known for its poor air quality. The city is an important industrial epicentre, and its air pollution problem is severe. Unpermitted and fugitive dust emissions are rampant in Xi'an and its neighbouring cities. There has been a lack of effective air pollution management policies in the past, and even recent efforts to improve air quality have been hampered by administrative loopholes and inadequate infrastructure. For instance, while Beijing successfully reduced its PM2.5 concentration by switching households from coal to natural gas, Xi'an struggled with an insufficient supply of gas and inadequate gas-transporting infrastructure. As a result, rural households in Xi'an continued to rely on coal for heating during the winter.
The Chinese government has identified the Fen-Wei Plain, which includes Xi'an, as a new focal point of air pollution control in its "2018-2020 Three-Year Action Plan for Winning the Blue Sky War". This plan allows for more flexibility in choosing cleaner energy sources and promises policy and financial support to ensure that alternative energy solutions are affordable for residents. The Xi'an municipal government has also revised its "Regulations on the Prevention and Control of Ambient Air Pollution" to hold local governments and emitting industries accountable for meeting targets.
Despite these efforts, air pollution continues to be a fundamental problem in Xi'an and has been linked to respiratory mortality. A time-series study assessed the respiratory mortality risks associated with short-term exposures to ambient air pollution (PM2.5, SO2, and O3) and meteorological parameters (temperature and relative humidity) from 2014 to 2016. The results showed that out of 7,965 cases of respiratory mortality, 62.9% were attributed to chronic lower respiratory diseases, 28.5% to influenza and pneumonia, and 8.6% to other forms of respiratory diseases.
While the study provides valuable insights into the potential relationship between air pollution and respiratory mortality in Xi'an, more research is needed to adequately describe the associations and mechanisms that trigger this health outcome in non-metropolis cities like Xi'an. The complex nature of ambient air pollutants and health effects can vary by location, and the impact of short-term exposure to air pollution on public health can no longer be neglected.

The Chinese government has identified the Fen-Wei Plain as a focal point of air pollution control
Xi'an, an ancient city in China, has been facing air quality issues. The city has struggled with an insufficient supply of gas and inadequate gas-transporting infrastructure, leading to a continuous reliance on coal for heating during the winter, especially in rural households. In addition, unpermitted and fugitive dust emissions have been rampant in Xi'an and its neighbouring cities. The local government has faced criticism for its ineffective air pollution management policies and lack of enforcement, with scandals revealing attempts to tamper with emission readings.
Recognising the urgent need to address these environmental concerns, the Chinese central government has identified the Fen-Wei Plain, which spans the provinces of Shaanxi, Henan, and Shanxi, as a critical area for air pollution control. This decision is part of the "2018-2020 Three-Year Action Plan for Winning the Blue Sky War", also known as the second phase of the "Ten Measures for Air". The Fenwei Plain has been designated as one of the three key regions for air pollution control since 2018, replacing the Pearl River Delta (PRD) region.
The Fenwei Plain faces significant air pollution challenges, with high levels of PM2.5, PM10, SO2, and NO2. The spatial autocorrelation of SO2 concentration has been decreasing yearly, and the impact of government policies on improving environmental pollution in the region is evident. The "Three-Year Action Plan to Win the Blue Sky Defense War" implemented in 2018, along with the Autumn and Winter Action Plan for 2018–2019, contributed to a notable decrease in PM2.5 levels.
To address the specific issues in the Fen-Wei Plain region, the new action plan offers flexibility in choosing cleaner energy alternatives and provides policy and financial support to ensure their affordability. Quantified goals have been set, targeting the elimination of major pollution sources, including capping total coal consumption, increasing railway freight transport, phasing out diesel-powered trucks, and controlling construction dust. These measures are designed to reduce air pollution and improve the environmental conditions in the Fen-Wei Plain and affected cities like Xi'an.

The Xi'an municipal government revised its air pollution regulations to hold key stakeholders accountable
Xi'an, an ancient Chinese city, has been facing severe air pollution issues. The city has struggled with an insufficient supply of gas and inadequate gas-transporting infrastructure, leading to a continuous reliance on coal for heating, especially during winters in rural areas. In addition, fugitive dust emissions and administrative loopholes in pollution-combatting operations have further exacerbated the problem.
Recognizing the urgent need to address these environmental challenges, the Xian municipal government has taken decisive action by revising its air pollution regulations. The updated "Regulations on the Prevention and Control of Ambient Air Pollution" aim to hold key stakeholders accountable for improving air quality.
Under these revised regulations, local governments at the municipal, district, and county levels are required to establish evaluation and accountability systems. These systems directly link the jurisdiction's progress in air pollution management to the performance assessments of officials. This approach ensures that those responsible for implementing effective measures are held accountable for their success or failure.
The emitting industries, another key stakeholder group, also face stricter requirements and higher financial penalties. They are mandated to maintain at least three years of original monitoring records and are subject to fines of up to C$6 million (RMB￥30 million) for non-compliance.
These regulatory changes are part of a broader effort to enhance air quality and protect human health in Xi'an and other cities in the Fen-Wei Plain region. The Chinese central government has identified this region as a new focal point of air pollution control, demonstrating its commitment to tackling environmental issues beyond previously targeted regions.
By revising its air pollution regulations, the Xian municipal government has demonstrated its dedication to addressing the city's air quality issues. Through increased accountability, stricter requirements, and financial incentives, these regulations aim to drive meaningful progress in improving the health and well-being of Xi'an residents.

The lack of effective air pollution management policies has contributed to the problem
Xi'an, China, is known to have poor air quality and severe air pollution. The city is an important industrial epicentre, and its air pollution is linked to industrial, energy, transport, and land-use factors.
Additionally, unpermitted and fugitive dust emissions remain rampant in Xi'an, and there have been scandals involving local officials tampering with emission readings. The municipal government has revised regulations to hold stakeholders accountable for failing to meet targets, but the focus on industrial emissions and the lack of comprehensive policy enforcement contribute to the persistent air pollution issues.
Furthermore, China's energy investments, both domestically and overseas, have largely been geared towards fossil fuels, which can lock countries into traditional, high-polluting energy sources. While China has made commitments to address climate change, such as the 2015 Paris Agreement, and set goals for reducing coal consumption, the lack of effective policy implementation at the local level in cities like Xi'an has hindered progress in improving air quality.
The health impacts of air pollution in Xi'an are significant, with studies showing associations between short-term exposure to air pollutants and respiratory mortality. The complex nature of ambient air pollutants and health effects varies by location, making it crucial to have effective policies and studies specific to non-metropolitan cities like Xi'an to adequately address the problem.

Rapid industrialization has led to intense levels of air pollution in China
China's rapid industrialization has resulted in severe air pollution, causing significant social, economic, and political issues. The country's past economic growth has been heavily reliant on fossil fuels, particularly coal, which has led to a rise in carbon dioxide emissions and other pollutants. This has contributed to China becoming the world's largest emitter of anthropogenic air pollutants, with the pollution spreading beyond its borders to other countries, including the United States.
While China has taken steps to address this issue, the transition from fossil fuels to cleaner energy sources has been challenging. Despite plans to reduce coal consumption, China continues to expand its coal-powered electricity generation capacity with new power plants. From 2017 to 2018, China's coal consumption increased, and it is forecasted that this trend will continue in the coming years. As a result, coal-powered industries will remain a significant source of pollution and carbon emissions.
The Chinese government has implemented policies such as the "2018-2020 Three-Year Action Plan for Winning the Blue Sky War" to tackle air pollution. This plan focuses on the Fen-Wei Plain, spanning Shaanxi, Henan, and Shanxi provinces, as a new priority area for air pollution control. The plan includes targets such as capping total coal consumption, increasing the use of railway freight transport, eliminating diesel-powered trucks, and controlling construction dust.
Additionally, the Xi'an municipal government has revised its "Regulations on the Prevention and Control of Ambient Air Pollution" to hold local governments and emitting industries accountable for failing to meet pollution reduction targets. Stricter requirements and higher fines have been imposed on emitting businesses, while governments at various levels are required to establish evaluation and accountability systems.
However, Xi'an continues to face challenges in effectively reducing air pollution. There has been an insufficient supply of gas and inadequate infrastructure for transporting it, leading to a continued reliance on coal for heating during winters, especially in rural areas. Moreover, dust emissions remain rampant, and scandals involving local officials tampering with emission readings highlight administrative loopholes in the city's pollution-combatting efforts.
