Environmental quality – municipal index

Municipal index for the theme Environmental quality is based on the indicators Green area within 200 metres of housing, share of urban population (%), Lakes with good ecological status, share (%), rivers with good ecological status, share (%), groundwater bodies with good chemical and quantitative status, share (%). The KPIs are normalised so that all municipalities’ values are placed on a scale from 0 to 100 where 0 is the worst and 100 is best (for some indicators, inverted scale is used). In the next step, the normalised indicator values are weighed together into indices at aspect level (currently, the theme is based on indicators in two aspects). This is done with averages, all indicators weighed together with the same weight in each aspect. Then the index at aspect level is weighed together to the thematic level according to the same principle and these values also fall between 0 and 100. The weighting is equal for all aspects of the theme.
