Countries with the Cleanest Air 2023
About This Dataset
Countries with the Cleanest Air 2023
The twenty countries with the lowest PM2.5 air pollution (micrograms per m3) in 2023, from World Bank figures for the 200 countries that reported that year. Greenland records the lowest figure at 1.64, with Northern Mariana Islands (2.68) and Guam (3.47) next. The population-weighted average exposure to fine particles smaller than 2.5 micrometres, in micrograms per cubic metre. It is modelled from satellite readings and ground monitors, because most countries have too few monitors for a direct national average.
Analysis
Greenland (1.64), Northern Mariana Islands (2.68) and Guam (3.47) record the three lowest figures. Across the twenty shown, values run from 1.64 up to 6.41, a spread of 4.77. Northern Mariana Islands, the next country up, records 1.63 times the figure for Greenland. 2 of the 20 sit within double the lowest figure, 3.28 or less. The chart shows the twenty lowest of 200 reporting countries, so it describes the bottom of the distribution rather than the world average. Countries recorded as zero are left out: the World Bank writes zero where a country did not report.

How the figures are calculated
- Values are shown as reported by the source. Nothing is rescaled, rebased or converted — the only changes are thousand separators and decimals shown to two places.
- Entities are ranked lowest-first, because on this measure a lower number is the better result.
