Report 2025<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The World Air Quality Report 2025, published by IQAir, presents a comprehensive assessment of air pollution across the globe, with a focus on PM2.5, fine particulate matter that poses significant risks to human health.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">PM2.5 particles are smaller than 2.5 micrometres, penetrate deep into the lungs and bloodstream, and are linked to cardiovascular, respiratory, and developmental diseases, particularly in children.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The report analyses data from 9,446 cities across 143 countries, sourced from over 40,000 regulatory monitoring stations and low-cost sensors, contributed by governments, research institutions, non-profit organisations, private entities, and citizen scientists.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">PM2.5 concentrations are reported in micrograms per cubic metre (\u00b5g\/m\u00b3), benchmarked against <a href=\"https:\/\/vajiramandravi.com\/upsc-exam\/world-health-organisation\/\" target=\"_blank\"><strong>World Health Organization<\/strong><\/a> (WHO) annual guidelines, facilitating international comparison and risk assessment.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Compared to prior editions, the 2025 report expanded geographic coverage, incorporating previously under-monitored regions and cities, thereby enhancing the global understanding of air quality patterns.<\/span><\/li>\n<\/ul>\n<h2><b>Key Highlights of World Air Quality Report 2025<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">The key findings of the World Air Quality Report 2025 reveal alarming trends in global and Indian air quality, underscoring both the widespread nature of PM2.5 pollution and the urgent need for effective mitigation strategies.<\/span><\/p>\n<p><b>Global Findings of World Air Quality Report 2025<\/b><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Only 14% of global cities met the WHO annual PM2.5 guideline of 5 \u00b5g\/m\u00b3 in 2025, down from 17% in 2024, highlighting deteriorating global air quality.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">130 out of 143 countries and territories failed to meet safe air quality standards.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Asia remains the worst-affected region, with all of the world\u2019s top 25 most polluted cities located in India, Pakistan, or China.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Pakistan emerged as the most polluted country, followed by Bangladesh and Tajikistan.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Wildfires, driven by climate change, and industrial emissions contributed significantly to global PM2.5 pollution, releasing about 1,380 megatonnes of carbon from biomass burning.<\/span><\/li>\n<li style=\"font-weight:
