Performance Metrics Interpretation

In Korea, crude steel output rebounded after the 2019 to 2020 dip while capacity utilization improved to 78.2% in 2023, yet production remains heavily BF-BOF driven at 83.7% in 2022, meaning the sector’s CO2 intensity is likely still higher than it would be with a larger EAF share that reached only 17.2% in 2022.
