  • According to the report the five most polluted countries for 2021 were India, Chad, Pakistan and Tajikistan.

According to IQAir’s report, global air pollution has declined to unhealthy levels by 2021. IQAir is a company that monitors global air quality, and sells air-purification products. The report found that pollution levels in every country and 97% cities exceeded the World Health Organization’s guidelines for air quality.

Frank Hammes (CEO of IQAir), stated that it was shocking that no major country or city is providing safe and clean air to its citizens as per the latest World Health Organization guidelines. “This report shows how much work is still needed to ensure that everyone has safe and clean air to breathe. Now is the time to act.

According to the report, India, Chad and Pakistan were the five most polluted nations in 2021. The United States was ranked 90th on this list.

The report stated that although air quality in the United States has improved over 50 years, fine particle pollution has increased by 7% between 2020-2021.

According to the report, the country’s dependence upon fossil fuels, the severity of wildfires and the varying enforcement levels of the Clean Air Act (from administration to administration) have all contributed to U.S. Air pollution. “Nationwide, 264 millions people lived in areas where PM2.5 levels were higher than the WHO annual guideline in 2021.”


The WHO standards for fine particle pollution were met in only 222 of the 6,475 cities analyzed worldwide, according to the report. The guidelines were met by New Caledonia, the French territory of France, and Puerto Rico and Virgin Islands, the United States territories.

Avinash Chanchal, Greenpeace India Campaign manager, stated in a statement that the report included. “We understand air pollution better than ever before how it damages our health and economies,” he said. “This report is a wakeup, revealing how people around the globe are denied clean air. Particulate matter is caused by burning fossil fuels such as coal, oil, and fossil gas, as well unsustainable development and agricultural activities. The development of renewable energy resources, clean-powered, accessible public transport are essential to address the air pollution crisis. Air pollution solutions can also solve the climate crisis. Clean, fresh air should be a human right and not a privilege.
