A method for calculating the carbon index, i.e. CO₂ emissions in the production of a ton of rolled steel and intermediate products is proposed. The data on the use of various types of energy carriers in the production of sinter, coke, cast iron, steel and rolled products are presented. Carbon indexes for the production of these products are calculated and ways to reduce them are analyzed. It is shown that the carbon index of the production of a ton of rolled steel obtained for converter steel is slightly lower than the same index for the EU steelmaking enterprises, but the total carbon index of Russian rolled steel is 6.6 to 46 % higher than the European one due to the low share of electrometallurgy use in our country. Increasing the proportion of steel smelted in electric furnaces is the only viable way to reduce the carbon footprint to European levels and lower the carbon tax stipulated in the Paris Climate Agreement.
