As one of largest energy consumption sector, China iron and steel (IS the energy saving potential in 2025 is 44 million tons of coal equivalent, and the contribution shares of three pathways are 51.1%, 34.1%, and 14.8%, respectively. Therefore, in the next few years, upgrading large and medium-sized advanced capacity has the largest contribution share of energy conservation in three pathways. The implementation of energy conservation mainly relies on the stock energy saving of the first two pathways. The key policy strategies should be promoting advanced energy-saving technology and phasing out backward production capacity in the next few years. Moreover, enhancing industrial concentration, promoting the EAF production, and optimizing the product structure should be encouraged to implement the energy-saving pathways.
