東京製鐵 List of Products and Services

Tokyo Steel's green steel product "Almost Zero" is a new low CO2 steel material born from a future-oriented spirit of challenge. The CO2 emissions from electric arc furnace steelmaking are approximately 0.4 tons per ton of crude steel, of which 0.3 tons is attributed to electricity (Scope 2). Therefore, by utilizing non-fossil certificates and "Demand Response (Up DR)," we have reduced CO2 emissions caused by electricity. The CO2 emissions of this product are calculated based on the "ISO 14067" and "Carbon Footprint Guidelines (Ministry of Economy, Trade and Industry, Ministry of the Environment)" and represent the carbon footprint (CFP). [Key Points] - CO2 emissions are "almost zero" (approximately 0.1 tons of CO2 emissions per ton of crude steel; for reference, blast furnace: about 2 tons, electric furnace: about 0.4 tons) - Cost-effective pricing unique to electric furnaces (Brand EX ¥6,000/ton) - Verified by a third-party organization - Products delivered to customers with the same quality and delivery times as regular products, regardless of type *For more details, please download the PDF or feel free to contact us.
