Abstract: Electric arc furnace steelmaking route does not play the role of carbon reduction in China due to the excessive use of hot metal. This unique route is called the “Chinese style” electric arc furnace steelmaking route. Employing the emission factor method， the Sankey diagram of CO₂ emissions of “Chinese style” electric arc furnace steelmaking route is built to explore the path of carbon emissions. The results show that the CO₂ emissions per ton of steel in the whole route are 3.070t， among which the CO₂ emissions from electric arc furnace steelmaking takes the largest share of 1.400t. Particularly， excessive CO₂ emissions of 1.419t are produced because of the utilization of hot metal for electric arc furnace steelmaking. The reason for the excessive use of hot metal is that China’s steel industry is in the developing period， the scrap steel index is low， the recovery and utilization system of scrap steel is incomplete and the price of industrial electricity is high.
