International Day of Clean Air for Blue Skies

Racing for Air

Air is our first contact with the world, and when one stops breathing, the end has arrived. Unfortunately, pollution of the very air we breathe is proving to be a significant environmental health risk of our time. Blue skies are visual indicators of clean air. “The International Day of Clean Air for Blue Skies” is observed on 7 September. The observation is to encourage innovation and policy action to reduce emissions and improve air quality. ~99% of the world’s population breathes polluted air, and air pollution is the second leading risk factor for premature death. The combustion of fossil fuels, industrial emissions, transportation, agricultural activities such as crop burning, and waste management contribute to it. Natural Sources also contribute—volcanic eruptions, dust storms, pollen, and sea spray. As we race for air, every step counts. Need to invest in renewable energy, eco-friendly agriculture, waste management, and deforestation prevention.

Air pollution knows no borders. Our solutions must be as global as the problem.
World Health Organisation

Air is our first contact with the world, and when one stops breathing, the end has arrived. Unfortunately, pollution of the very air we breathe is proving to be a significant environmental health risk of our time. Blue skies are visual indicators of clean air. Clean air allows sunlight to scatter naturally, giving the sky its blue hue (Rayleigh scattering). Pollutants in the air absorb and scatter light differently, leading to the sky losing its blueness. “The International Day of Clean Air for Blue Skies” is observed on 7 September. The observation is to encourage innovation and policy action to reduce emissions and improve air quality. 99% of the world’s population breathes polluted air, with children and older people bearing the brunt of its effects. Air pollution is the second leading risk factor for death (~8.1 million premature deaths annually), and the global economic cost is estimated at ~$8.1 trillion per year. This year’s theme is “Racing for Air”, emphasising the urgency of accelerating solutions and urging a shift from problem-focused narratives to solution-driven action. We are not just racing for air; we are racing for life, equity, and a sustainable future. It is a preventable crisis, and the solutions are within reach, says António Guterres, UN Secretary General.    

Clean Air is Not a Luxury, But a Basic Human Right.
United Nations Environment Programme

Measured by average PM2.5 concentration, Bangladesh, Pakistan, and India are topping the list of the most polluted countries. Cities like Delhi, Dhaka, and Lahore report air quality levels crossing hazardous levels. China was once among the most polluted countries globally, but it is showing improvement. Countries like Finland, Iceland, and New Zealand top the list of least polluted countries, benefit from renewable energy, low population density, and vast natural landscapes that act as air filters.

A complex mix of natural and human-made sources causes air pollution. Combustion of Fossil Fuels, Industrial Emissions, and Transportation contribute to it. Agricultural Activities, especially crop burning, exacerbate the situation. Waste Management, due to the open burning of garbage, landfills, and incinerators, is exacerbating the problem. Natural sources, like volcanic eruptions and dust storms, also contribute.

Early humans used fire for cooking and warmth, releasing smoke and particulates into the air. The Industrial Revolution marked the true beginning of large-scale air pollution. The term “smog” (a combination of “smoke” and “fog”) was coined in the early 20th century. With enhanced urbanisation and motorisation, airborne pollutants began to travel across borders, making air pollution a global issue. Science and technology are providing tools for pollution monitoring through satellite imagery and AI-based forecasting.   

Ancient Indian scriptures offer profound insights into the relationship between humans and nature, including early reflections on air quality and environmental ethics. The Rigveda and Atharvaveda contain hymns that praise air as a life-sustaining force.

Blue Skies Reflect the Silent Grace and Whispers of The Wind’s Soft Care.
Every Child Deserves Blue Skies to Call Their Home.

Clean air is crucial for maintaining health, promoting climate resilience, and advancing social justice. “The International Day of Clean Air for Blue Skies” is not just a day of reflection but a call for action. As we race for air, every step counts. Need to invest in renewable energy, eco-friendly agriculture, waste management, and deforestation prevention.

The Race for Clean Air is Not About Speed – It is About Direction.
