http://www.urbanemissions.info/: In 2015, the World Health Organization (WHO) released a compilation of air quality data across the world and estimated the corresponding health impacts on premature mortality and morbidity – Delhi is among the top 10 for cities with the worst air quality. Air pollution in (urban and rural) India is a growing public concern, and city of Delhi (its capital) is one of the most studied city with a disproportionate share of media attention. Yet, we do not seem to have decisive answers to simple questions like how polluted is the city, what are the main sources, and where to start to control pollution in the city.
Bloomberg, John Trozi: Deaths from pollution exceeds many other cases including high-sodium diet, obesity, alcohol, road accidents, and malnutrition. Nine million annual deaths and a economic damage of trillions of dollars.
NY Daily News: Environmental pollution — from filthy air to contaminated water — is killing more people every year than all war and violence in the world. More than smoking, hunger or natural disasters. More than AIDS, tuberculosis and malaria combined. One out of every six premature deaths in the world in 2015 — about 9 million — could be attributed to disease from toxic exposure, according to a major study released Thursday in The Lancet medical journal. The financial cost from pollution-related death, sickness and welfare is equally massive, the report says, costing some $4.6 trillion in annual losses — or about 6.2% of the global economy.
World Nuclear News: According to the International Energy Agency, IEA, some 6.5 million deaths annually are linked to outdoor and indoor air pollution, "with the number set to increase significantly in coming decades unless the energy sector takes greater action to curb emissions." "Energy production and use - mostly from unregulated, poorly regulated or inefficient fuel combustion - are the most important man-made sources of key air pollutant emissions: 85% of particulate matter and almost all of the sulfur oxides and nitrogen oxides." NOTE: This far exceeds realistic projections of deaths from increased carbon dioxide in the atmosphere. CO2 is absolutely essential for life on Earth. "The more the better."
