ArcelorMittal Brazil launched a goal of reducing its CO ₂ emissions by 10% by 2030 on 8 June 2021. The commitment was announced during an event to disseminate the ArcelorMittal 2020 Sustainability Report, as part of the company''s actions to mark Environment Week. The goal established for the ArcelorMittal Group''s operations in Brazil is an intermediate step within the steel producer''s global effort to become carbon neutral by 2050. Globally, the company has already committed to investments of around BRL 1.9 billion for the development of carbon neutral technologies by the ArcelorMittal Group''s Research & Development Centers.
Among the initiatives to be developed and implemented by ArcelorMittal Brazil are the increase in the use of scrap as a raw material, the use of natural gas and the optimization of the use of charcoal in the units that already use the fuel.
Globally, ArcelorMittal is studying alternative technologies to use process gases containing CO2, producing ethanol for consumption and use in the chemical industry. A process for the use of wood residues for the production of biofuel is also under development, similar to the process for the production of charcoal that is already used in Brazil. A promising technology, at an early stage of development at ArcelorMittal Hamburg Germany will allow the replacement of fossil carbon by hydrogen produced with clean energy to reduce iron ore.
In ArcelorMittal''s Long Steel segment, a large part of the steel production is obtained through the use of steel scrap in electric furnaces, which has a lower CO2 emission intensity. In addition, the Juiz de Fora unit uses charcoal as a bio-reducing agent for iron ore in its blast furnaces. Charcoal comes from planted forests, and the pig iron production process allows the CO2 cycle to be closed, the CO2 emitted is sequestered by ArcelorMittal BioFlorestas'' renewable forest stock. Thus, in addition to contributing to the climate, forest management favors biodiversity.
In the Flat Steel segment, the Tubarão industrial plant, the Group''s largest plant in Brazil, is self-sufficient in electricity, using the gases generated in its processes, with an internal generation equivalent to the consumption of approximately 1 million people a year. The unit is also a pioneer among steel producers in registering and trading carbon credits and has two Clean Development Mechanism Projects approved by the United Nations Executive Committee on Climate Change. One of them stands out for being the first project approved for an integrated steel company in the world and co-generates electricity through the use of gases generated in the steelworks. The other project adopted with the generation of carbon credits is the recovery of heat from one of the coking plants, which produces an average of 170 MW of electricity, with the potential to generate credits of 2.5 million tons of CO2 in ten years.
