Abstract：The iron and steel industry is a typical resource- and energy-intensive industry and one of key industries for the energy conservation and emission reduction. The progress and problems in the energy conservation and emission reduction achieved by China's iron and steel industries since the 12th Five-Year Plan were summarized. Based on the dynamic material flow analysis method， the steel demand forecast and the scrap recovery model were constructed. Based on the evaluation of 35 energy saving and emission reduction technologies， combined with the energy consumption and CO2 emission models， the energy saving potential of the China's iron and steel industry by 2050 and the impact of various factors were analyzed. Finally， several ways to improve the energy efficiency were proposed which provides the theoretical guidance for the green and low-carbon transformation and sustainable development of the China's iron and steel industry.
