The paper deals with possibilities of low carbon technology application in metallurgy. It sums up the world wide experience with them and presents possibilities of their application in metallurgical production in view of carbon dioxide emission responsible for greenhouse effect and global warming of the Earth. It summarizes research projects in this field and presents the results and conclusion resulting from them. It is aimed at the possibilities of low carbon application in sinter and subsequently in blast furnace process. It presents research on reducibility of metallurgical ekosinter produced with share of biomass in comparison with sample of industrial one. It describes the testing methodology carried out in accordance with ISO 4695:2007. The samples were tested in reduction atmosphere created by 40% CO2 and 60% N2 simulating conditions in blast furnace aggregate at temperature 950°C. The obtained results confirmed better reducibility rate of ekosinter which reached the reduction index (dR/dt) 1.15, in comparison with industrial sinter of reduction index 0.83.
