This table provides metadata for the actual indicator available from UK statistics closest to the corresponding global SDG indicator. Please note that even when the global SDG indicator is fully available from UK statistics, this table should be consulted for information on national methodology and other UK-specific metadata information.
Annual mean levels of fine particulate matter (e.g. PM2.5 and PM10) in cities (population weighted)
Annual mean levels of fine particulate matter (e.g. PM2.5 and PM10) in cities (population weighted). The mean annual concentration of fine suspended particles of less than 2.5 microns in diameters (PM2.5) is a common measure of air pollution.
|Unit of measurement
Annual mean (micrograms per cubic meter)
The mean annual concentration of fine suspended particles of less than 2.5 microns in diameters (PM2.5) is a common measure of air pollution. The mean is a population-weighted average for urban population in a country, and is expressed in micrograms per cubic meter. Air pollution consists of many pollutants, among other particulate matter. These particles are able to penetrate deeply into the respiratory tract and therefore constitute a risk for health by increasing mortality from respiratory infections and diseases, lung cancer, and selected cardiovascular diseases
The annual urban mean concentration of PM2.5 is estimated with improved modelling using data integration from satellite remote sensing, population estimates, topography and ground measurements (WHO, 2016a; Shaddick et al, 2016).
The data for this indicator are provided by WHO, which use data from the Defra(Department for environment, food & rural affairs), who are the main producer of air quality statistics in the UK. The most recent data on air-pollution in the UK can be found in the Air Information Resource and the publication on air quality .
Please note that the SDG indicator is different from the PERT (Populatoin Exposure Reduction Target) in the Air quality targets in the Environment act , due to a difference in methodology.
Data follows the UN specification for this indicator. This indicator has been identified in collaboration with topic experts.
