英文摘要	The critical role of the iron and steel industry in decarbonizing global energy systems calls for refined strategies of climate mitigation. Here, based on a newly developed database of individual iron and steel facilities worldwide, we explore the distinct differences in age-to-capacity ratio and emissions intensity of primary steelmaking plants. We customize regional cost-effective decarbonization strategies by targeting a certain proportion of plants. We find that the more effective indicator for targeted decarbonization in developing regions is emissions intensity, while for developed countries it is age-to-capacity ratio. Whichever indicator we use to target plants, the strategy of transformation towards secondary steelmaking is generally more cost-effective than efficiency improvement in most cases, although obvious regional priorities exist. Our results emphasize the region-specific priorities of mitigation indicators and strategies in targeting plants, which help with designing short-term, cost-effective strategies for reducing steel-related CO2 emissions. The decarbonization of the global iron and steel industry is important for energy systems mitigation. Using a facility-level database, this Article presents cost-effective, region-specific strategies targeting plants with a large age-to-capacity ratio and/or high emissions intensity.
