Summary/Abstract: The aim of the paper was to attempt to evaluate changes in the degree of pollution at the level of Voivodeships in the years 2004- 23 2014. Assessment was carried out by construction of Voivodeship rankings. These rankings were created on the basis of synthetic variables resulting from the normalization of variables by unitarisation zeroed method and the quotient mapping. It was also paid attention to the problem of outliers. It was proved that depending on the approach to this problem, it can be obtained significantly different results for clustering Voivodeships into classes.
