Mostly True
Emissions among South Korea's major corporations diverged last year, with power generation and steel companies reducing their carbon output while semiconductor and IT companies recorded increases, according to a review of primary sources.
Carbon emissions from large companies did not move in a single direction over the past year. Power generation and steel firms — traditional heavy emitters — posted declines in their emissions. In contrast, companies in the semiconductor and IT sectors saw their emissions rise.
The semiconductor industry's upward trend reflects the sector's expanding production activity, as chipmakers including Samsung and SK hynix operate energy-intensive fabrication lines. IT companies likewise registered higher emissions over the period.
The divergence suggests that decarbonization progress among heavy industry has been partially offset by growth-driven emissions elsewhere in the economy, particularly in industries tied to chip manufacturing and data infrastructure.
Based on the available evidence, the claim is assessed as mostly true.
Verdict: Mostly True
