Developing direction to improve blast furnace smelting technology to increase energy efficiency and improve environmental performance by reducing carbon dioxide emissions is an urgent task today in global metallurgy. According to the International Energy Agency (IEA), by 2050 blast furnace production will remain the dominant link in steel production, as it is the most costeffective with a thermal efficiency of up to 90 % or more. Blast furnace production consumes 40–75 % of the energy resources of the metallurgical plant, so the blast furnace has the greatest potential to reduce carbon dioxide emissions. The paper presents the results of the analysis of directions of reduction of carbon dioxide emissions and reduction of carbon consumption in blast furnace production due to improvement of existing technologies and introduction of innovative technologies of CO2 emission reduction based on injection of blast furnace fuel additives into the blast furnace; coke oven gas; washed flue gas. Paul Wurth, ThyssenKrupp and Primetals are world leaders in the development of technical and technological solutions to reduce CO2 emissions in blast furnace production. But the solutions offered by foreign companies are not always applicable to blast furnace production in Ukraine, they require scientific study and adaptation to the conditions of Ukraine, including the energy balance of enterprises, raw material conditions, blast furnace equipment, technology and competitiveness of iron-carbon intermediate, the presence of energy. Ukraine needs to develop its own concept of reducing CO2 emissions, taking into account the competitiveness of iron-carbon intermediate, which depends on the energy intensity of blast furnace production. Therefore, it is very important to assess and analyze the directions of reduction of CO2 emissions in metallurgy abroad for further development of blast furnace smelting regimes that reduce carbon dioxide emissions in relation to the existing and future conditions of metallurgical enterprises of Ukraine.
