Environmental Performance
Atmospheric emissions
In 2020 total emissions of atmospheric pollutants across all businesses of Severstal reduced by 9% from 2019.
Severstal Russian Steel reduced its emissions mostly through the introduction of combined blowing in Cherepovets Steel Mill converters, more than four-fold reduction in working hours of Sintering Machines 4–9 without the bed layer at Cherepovets Steel Mill Sinter Plant 2 following the completion of maintenance work, and the sale of Balakovo Long Product Mill in 2020.
Severstal Resources reduced pollutant emissions of pollutants in 2020 from the previous period, mostly due to greater methane recycling in Vorkutaugol mine boilers..

Reducing water consumption
Total water intake in 2020 reduced by 6.4% to 66,022 thousand cubic metres. The overall reduction in water intake reflects greater use of storm water collectors.
Water intake from surface bodies reduced by 8.5%
Water intake from underground sources
Water intake from alternate sources for production needs reduced by 5%
Water intake from Vodokanal municipal utility reduced by 5.4%
