“…The area covered within this study boundary is referred to as "airshed" and in general terms a "study domain". Khan et al (2024) [3] reviewed air quality studies conducted across the globe using the airshed concept. While confusing, there is no set definition for how big or small can an airshed be.…”

“…(2) to study emission intensities and enforce regulations at state(s) level or multiple provincial level, the examples of the establishment of the California Air Resources Board in the United States and Beijing-Tianjin-Hebei region airshed in China, involved as assessment of resource allocations and knowledge sharing mechanisms among multiple stakeholders crossing administrative boundaries [6,7]. (3) to study the impact of local emissions and evaluate the boundary contributions via chemical transport modeling, urban airsheds were defined for 20 Indian cities [8]. (4) Singapore, a country and a city, has to work in a nested airshed environment -a smaller airshed to study the contributions of the local emission sources at great detail and a larger airshed covering the neighboring countries Malaysia and Indonesia, which account for a large portion of Singapore's pollution during the open fire season [9].…”

“…While the concept of defining airsheds and conducting air pollution analysis are officially in practice in the United States and the European Union, the concept is still in its nascent stage for the low-and middle-income countries (LMIC) [3]. To date, most of the air quality management studies in LMIC are limited to the administrative boundaries, such as ambient monitoring campaigns [10].…”

Air pollution knows no boundaries, which means for a city or a region to attain clean air standards, must not only look at the emission sources within its own administrative boundary, but also at sources in the immediate vicinity and those originating from long-range transport. And there is a limit to how much area can be explored to evaluate, govern, and manage as designated airsheds for cities and larger regions. This paper discusses the need from an official airshed framework for India’s air quality management, urban airsheds designated for India’s 131 non-attainment cities under the national clean air programme, and proposes climatically and geographically appropriate regional airsheds to support long-term planning. Between 28 states, eight union territories, 36 meteorological sub-regional divisions, and six regional meteorological departments, establishing the proposed 15 regional airsheds for integrated and collaborative air quality management across India is a unique opportunity.

“…Many factors driving air pollution, notably, the combustion of fossil fuels, are also significant contributors to greenhouse gas emissions [28]. Consequently, initiatives aimed at mitigating air pollution present a mutually beneficial strategy addressing both climate concerns and public health [29][30][31]. By reducing the burden of diseases linked to air pollution, such policies contribute to both the immediate and long-term efforts to alleviate the impacts of climate change [1].…”

Presently, there is growing discourse surrounding climate change, global warming, and the possibility of urban smog. Daily, we encounter air pollutants unwittingly, often oblivious to the substantial adverse impacts they may impart on our health. This manuscript furnishes a thorough examination of the shifts in the concentrations of distinct air pollutants, namely, sulphur oxides (SOx), nitrogen oxides (NOx), and particulate matter PM2.5 and PM10, within the contexts of the United Kingdom (a country progressively transitioning to alternative energy sources) and Poland (a country in the EU with the second lowest climate policy evaluation in the climate change performance index or CCPI) from 1970 to 2020. This comparative study between the two countries clearly showed the importance of the transition to clean energy sources. The UK’s efforts towards cleaner energy sources have led to reduced emissions of sulphur oxides (SOx) and particulate matter. In contrast, Poland’s heavy dependence on energy primarily from coal over the years has resulted in elevated pollution levels, notably in the concentration of pollutants such as particulate matter. This study also revealed that changes in emissions predominantly stem from technological advancements and economic activities. Additionally, political regulations and the gradual phase-out of specific fuels or energy-rich substances and their substitution with alternative energy sources have also imparted considerable influence.
