    The question of rating of the condition of the air in the regions of Ukraine is very relevant. An important component is the choice of the optimal rating method. The purpose of the work is to review methodological approaches to the rating of the condition of atmospheric air (on the example of the city of Chernivtsi). The results of the calculation of CAPI and I5 showed that the maximum was noted in 2017 due to abnormally high concentrations of phenol, the minimum was in 2018. The value of I5 is fully correlated with the value of CAPI, which means the expediency of using I5 in particular for rating. According to the value of I5, the quality of the air is characterized by the level of "slightly polluted". Nitrogen dioxide, hydrogen fluoride and formaldehyde were included in the "three" priority pollutants. The value of In changes similarly to CAPI. In comparative analysis for individual regions, it can be used as an alternative indicator. The dynamics of changes in the index AQI for individual pollutants are similar to their time course. At index values of 100%, the air quality is characterized as "poor", although this corresponds to the level of the MRS. According to indicators of sustainable development in the "Ecological systems" category, a significant deterioration of circumstances is noted, for the "Environmental load" category - a significant improvement in circumstances is noted. The condition of the air underwent positive changes until 2018. Since 2019, indicators have deteriorated.
