This report uses the US Air Quality Index (AQI) to visualize PM2.5 levels that exceed the WHO target. The index translates daily pollutant concentrations into 6 categories ranging from “good” (green) to “hazardous” (maroon).
This 2021 World Air Quality Report presents an overview of the state of global air quality in 2021. The report is based on PM2.5 air quality data from 6,475 cities in 117 countries, regions
18 Μαρ 2020 · The US AQI is among the most widely recognized index for communicating air quality. The index converts pollutant concentrations into a color-coded scale of 0-500, where higher values indicate increased health risk.
supports this need. The Air Quality Life Index (AQLI) shows that strong pollution policies pay back in additional years of life for people across the world. The AQLI’s latest data reveals that reducing air pollution to meet the World Health Organization’s (WHO) guideline would add 2.2 years onto global life expectancy.
This article published in the WHO bulletin in 2023, presents an overview of close to 50 years of WHO's activities in gathering air quality data and their use in global assessments and efforts to reduce health risks caused by air pollution.
In the State of Global Air 2024 interactive app, you can explore, compare, and download data and graphics reflecting the latest air pollution levels and associated burden of disease for over 200 individual countries, territories, and regions, as well as track trends from 1990 to 2021.
Displaying up-to-date information for Europe, users can gain insights into the air quality in individual countries, regions and cities. The Index is based on concentration values for up to five key pollutants, including: particulate matter (PM 10); fine particulate matter (PM 2.5); ozone (O 3);
