Abstract In this study, we selected 22 energy-saving and emission-reduction measures, evaluated the emission reduction potentials, reduction costs and co-benefits, and tried to get the optional path for the CO2 mitigation of China’s iron and steel industry. The results showed that: based on the current steel output and production structure, the total emission reduction potentials are 146.8Mt CO2, 314.2kt SO2, 265.7kt NOx and 161.5kt PM10, respectively, accounting for about 9.7%, 13.1%, 27.3% and 8.9%. If consider energy-saving benefits, 10measures are cost-effective and the total emission reduction potentials are 98.0 Mt CO2、210.0kt SO2、211.0kt NOx and 89.0kt PM10, respectively. If we consider the energy-saving and co-benefits, 14measures are cost-effective and the total emission reduction potentials are 123.4 Mt CO2、264.0kt SO2、234.0kt NOx and 130.0kt PM10, respectively. For the iron and steel industry, we should consider the reduction costs, energy savings and co-benefits, based on the emission reduction cost and choose the most cost-effective measures.
