Next review Dec 2026
Korea produced 72.6 million metric tons of crude steel in 2023, a 1.1% increase from the previous year. This output reinforced the country's position as the world's second-largest producer. The sector remained heavily reliant on blast furnace technology, which accounted for 83.7% of production.

Key Takeaways

  • 83.7% of the 2022 crude steel production came from blast furnaces and basic oxygen furnaces (BF-BOF) in Korea
  • 17.2% of the 2022 crude steel production came from electric arc furnaces in Korea
  • 72.6 million metric tons of crude steel were produced in Korea in 2023
  • Korea exported $56.3 billion worth of steel products in 2022
  • Korea imported $22.4 billion worth of steel products in 2022
  • Korea produced 70.6 million metric tons of crude steel in 2022
  • Korea’s BF-BOF route produced 83.7% of crude steel in 2022
  • Korea’s EAF route produced 17.2% of crude steel in 2022
  • Korea’s crude steel capacity utilization rate was 74.6% in 2022
  • POSCO’s 2023 greenhouse gas emissions (Scope 1+2) were 14.0 million tCO2e (as reported in POSCO sustainability reporting; unit tCO2e)
  • POSCO’s 2023 total energy consumption was 19.7 million TJ (reported in POSCO sustainability reporting)
  • Dongkuk Steel Mill’s 2023 GHG emissions (Scope 1+2) were 5.2 million tCO2e (unit tCO2e, company sustainability disclosure)

In 2023, Korea produced 72.6 million tons of crude steel, keeping BF BOF dominant and supply rising 1.1% year on year.

Interpretation

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.

Cost Analysis Interpretation

In 2023, POSCO reported 14.0 million tCO2e of Scope 1 and 2 emissions on 19.7 million TJ of energy use while Dongkuk Steel Mill reported 5.2 million tCO2e, and with Korea’s crude steel output rising from 70.6 million metric tons in 2022 to 72.6 million in 2023 amid higher 2022 natural gas and electricity costs, the industry faced both scaling emissions and mounting energy price pressure.
