Methodological sheet of the indicator available for the Autonomous Community of the Basque Country.
| Available indicator |
Average annual levels of fine suspended particles ($PM_{2.5}$ and $PM_{10}$) in cities (weighted by population) |
|---|---|
| Target |
11.6 By 2030, reduce the adverse per capita environmental impact of cities, including by paying special attention to air quality and municipal and other waste management |
| Goal |
11- Make cities and human settlements inclusive, safe, resilient and sustainable |
| Definition |
Average concentration of suspended particles smaller than 10 microns ($PM_{10}$) or 2.5 microns ($PM_{2,5}$) in municipalities with more than 50,000 inhabitants weighted according to population |
| Theoretical formula |
\[CMPM^{t} = \frac{\sum_{m \in M^{t}}CMPM_{m}^{t}}{\sum_{m \in M^{t}}P_{m}^{t}}\]
where: $M^{t} $ = set of municipalities with more than 50,000 inhabitants where there are monitoring stations that participate in the evaluation of air quality in year $t$ $CMPM_{m}^{t} $ = average concentration of suspended particles in the municipality $m$ in year $t$ $P_{m}^{t}$ = population of the municipality $m$ in year $t$ |
| Available disaggregations |
