Cooperative control of regional transboundary air pollutants

Abstract

Background: After food and water, clean air is essential for continuity of life on the planet. Complex trans-boundary air pollution problem is often linked to sustenance and eutrophication. Air pollution problem has no universal conventions like Montreal and Kyoto protocols in case of refrigerants, except regional cooperative solutions. Polluter-pays principle is typically restricted to the source country. Under article 16, International Environment Law mentions the polluter-pay principle without any legitimate power to mitigate the transboundary air pollution risks. Mongolia, Botswana, and Pakistan are ranked as the most polluted countries, although their accumulative emissions are lesser than any of the coal power producing countries. Results: China, South Africa, and India produce 68-79% of their electricity using coal-fired power plants, emitting harmful pollutants into the common air. Regional winds drive upwind smog into their adjacent downwind countries like Pakistan. This paper compares the published transboundary air pollutant flows data of the most polluted countries (Mongolia, Botswana, Pakistan) with the cleanest ones (Estonia, Mauritius, Australia). Conclusions: Air pollution externality problem can only be solved either by regional cooperation or global environment law which yet does not exist. Drawing an analogy from water contamination laws, this work proposes an extension of the polluter-pays principle to transboundary air pollutants to compensate the public losses. We should collectively go for the international environmental law as we cannot divide air like land. Industrialization near the border may be banned to avoid air pollutant migrations to neighbors.

Preliminary Assessment of Air During COVID-19 Lockdown: An Unintended Benefit to Environment

“…Environmentally, the city of gardens 'Lahore' has been converted into the city of concrete in the past three decades. Urban sprawl (Liaqat et al, 2017;Sabir and Anjum, 2017), economic development (Pervaiz et al, 2019), industrial expansion (Raja et al, 2010;Rehman et al, 2019) vehicular emissions (Ilyas, 2007;Shirwani et al, 2019;Ali et al, 2020) and biomass burnings (Sidra et al, 2015;Abas et al, 2019) are the variety of sources deteriorating the natural environment (Pervaiz et al, 2019) of the city. On the top, semi-arid climate of the city strongly supports to accumulate the air pollutants in the atmosphere (Shahid et al, 2013).…”

Review of carbon dioxide (CO 2 ) based heating and cooling technologies: Past, present, and future outlook

“…The centuries‐long journey from fire to wire gave prosperity and economic growth at the expense of invisible climate change calamity. Dire famines, flash floods, acidic waters, and heat and cold waves have started affecting the global community . The people who never contributed to greenhouse gas (GHG) emissions might be the first victims of climate change aftereffects.…”
