Initiatives to carbon-neutrality in R&D of steel products

We have formulated a target of reducing total CO2 emissions by 30% by 2030, compared to the 2013 baseline and of achieving carbon neutrality in 2050. We are working to develop and actually implement breakthrough technologies in steelmaking process and eco-friendly products. Our eco-friendly steel products have advanced functions and reliability and are used in diverse areas including energy, transportation and construction equipment, and household products. They typically help our customers become more efficient while making their products lighter or lengthening product life. That translates into the saving of resources and energy, and into a reduction in CO2 emissions at the point of use at our customers, thereby contributing to lessening the environmental impact. These steels that support carbon neutralization must have various environmentally friendly properties, such as high strength, high toughness, and resistance to hydrogen embrittlement. Here, we provide an overview of the metallurgy required for the development of these advanced steel materials, with a particular focus on their suitability for a hydrogen society.
