The 2023 IQAir World Air Quality Report reveals a disparity in access to crucial air quality data, particularly in developing countries, where the scarcity of monitoring infrastructure leaves populations vulnerable to the unseen dangers of polluted air.
Leveraging data from low-cost sensors alongside traditional air quality monitoring stations, the report not only highlights these severe disparities in air pollution exposure and data but also serves as a call to action for the international community to expand and enhance air quality monitoring networks.
