South Korea has denied reports that it was discussing semiconductor investments as the first US project. The statement addresses recent market speculation regarding potential bilateral trade dynamics between the two nations.

The denial clarifies the current status of negotiations, countering claims that specific talks were underway to position chip manufacturing as a primary investment vehicle for US capital in South Korea.

What the Numbers Show

No financial data or quantitative metrics were disclosed in the source material. The report is purely qualitative, focusing on the denial of negotiations rather than any financial outcomes or deal values.

Researchers from Pusan National University have developed a modeling framework to simulate the effects of proposed reforms to Phase IV of the Korean Emissions Trading Scheme (K-ETS) on South Korea's electricity market. The study, published in Energy Policy, indicates that changing benchmarking mechanisms alone is insufficient to drive decarbonization and must be combined with expanded auctioning, higher carbon pricing, and complementary support systems.

South Korea launched the K-ETS in 2015 to limit greenhouse gas emissions, with the power sector expected to contribute nearly 44.3% of the country's total national emissions reduction target. The government has proposed reforms for the fourth implementation phase (2026-2030), largely based on the European Union Emissions Trading System (EU-ETS). However, market conditions in Korea differ significantly from those in the EU, raising questions about whether similar outcomes will be achieved.

Policy Variables Analyzed

The research team, led by Assistant Professor Dowon Kim, applied a computational model of the Korean electricity market to multiple scenarios involving three key policy variables:

• Benchmarking mechanism: Shifting from a fuel-specific standard to a uniform benchmark for all power plants regarding free emission allowances.
• Auctioning share: Increasing the percentage of allowances companies must purchase through auctions.
• Carbon pricing: Raising the cost charged for producing emissions.

Impact on Power Generation Companies

Analysis revealed that shifting from a fuel-specific to a uniform benchmark reduced free emission allowances and profits for fossil fuel-based power generation companies. Coal-based companies faced sharp profit declines, whereas natural gas-based companies were less affected.

Increasing the auctioning share raised the cost of generating an additional unit of electricity, particularly for coal-based companies. This provided a gentle nudge toward lower-emission fuels like gas, though the effects of these two reforms were described as small.

The strongest impact came from increasing carbon pricing, which raised both electricity generation and emissions costs more for coal than for gas. This led companies to partially shift from coal to gas generation.

What the Numbers Show

The data highlights a divergence in cost sensitivity between fuel types under the proposed reforms. While both coal and gas generators face increased costs, the disproportionate impact on coal-based profits suggests that carbon pricing acts as a more effective lever for fuel switching than benchmarking or auctioning adjustments alone. This aligns with the finding that integrated policies are necessary to drive decarbonization while protecting sector stability, given the highly centralized nature of Korea's electricity market which limits companies' ability to recover rising costs through consumer charges.
