EU CBAM Takes Effect — Impact on Korean Exporters (2025 Analysis)

EU CBAM Takes Effect Today — What It Means for Korean Exporters
“When carbon becomes a tariff.” The EU’s CBAM now tests the competitiveness of Korean exporters.
Summary

As of November 18, 2025, the EU’s Carbon Border Adjustment Mechanism (CBAM) is officially in effect. Korean exports—particularly steel, aluminum, cement, and fertilizer—will now face additional costs based on carbon emissions. This shift directly affects price competitiveness, profit structures, and long-term market access. Companies must urgently strengthen carbon reduction technologies, process efficiency, and supply chain restructuring.

1️⃣ Background and Purpose of CBAM

The European Union (EU) has long strengthened its climate policies to curb carbon emissions and maintain industrial competitiveness. Among these measures, CBAM stands out as one of the most impactful, effectively functioning as a "carbon tariff" on imported goods.

Why CBAM?

EU companies already pay substantial carbon costs under the Emissions Trading System (ETS). Competing against overseas firms with no such burden puts them at a disadvantage, prompting the EU to introduce CBAM.

Policy Objective

CBAM is not simple protectionism — it is a mechanism designed to push global industries toward low-carbon production. The message is clear: “If you export to the EU, you must bear similar carbon costs.”

2️⃣ Core Structure and Covered Sectors

Under CBAM, exporters must submit detailed carbon emission reports and purchase CBAM certificates to offset emissions embedded in their products.

Sectors Covered in 2025

The EU currently applies CBAM to six high-emission industries:

  • Steel
  • Aluminum
  • Cement
  • Fertilizer
  • Electricity
  • Hydrogen

Future Expansion

By 2030, CBAM is expected to expand to include chemicals, glass, paper, automotive components, and additional industrial sectors — creating mounting pressure on Korean manufacturers.

3️⃣ Impact on Korean Export Companies

CBAM will reshape the fundamentals of Korean manufacturing — processes, supply chains, and energy sources — far beyond simple cost increases.

1) Rising Cost Burden

High-emission industries face significant pressure as CBAM certificate purchases reduce export margins. Steel manufacturers using blast furnace methods will be hit hardest, while electric-arc furnace producers hold a relative advantage.

Cost Simulation Example

With an ETS price of €80 per ton, a product emitting 1 ton of carbon must pay an equivalent CBAM charge. In short, carbon competitiveness now directly equals export competitiveness.

2) Structural Risks for Korean Industries

Korean manufacturing still relies heavily on fossil-fuel-based processes. Companies with high EU export dependence face larger impacts, and SMEs lack the resources to build required monitoring systems.

Key Challenges

  • Rising costs for carbon data collection and verification
  • Burden of energy transition investments
  • Lack of low-carbon process infrastructure
  • Costs of building EU-compliant reporting systems
Carbon data governance is becoming the new standard for EU market competitiveness.

4️⃣ Corporate & Government Response Strategies

1) Corporate Strategies

Korean companies must rethink carbon reduction as a survival strategy, not a voluntary ESG initiative.

Three Mandatory Steps

  • Accurate Measurement — Build reliable carbon monitoring systems
  • Low-carbon Processes — Shift to electric-arc furnaces, efficient equipment
  • Supply Chain Alignment — Manage carbon emissions of raw materials

2) Government Strategies

The transition is too large for companies to manage alone — government support is essential.

Government Support Areas

  • Expanded R&D for carbon-reduction technologies
  • Carbon data platform support for SMEs
  • Tax incentives and financial assistance
  • Strengthened cooperation channels with the EU

5️⃣ Importance of Supply Chain & Technology Shift

CBAM cannot be solved by improving only the final manufacturing process. Emissions embedded in the entire supply chain directly affect export pricing.

Key Points in Supply Chain Carbon Management

Securing low-carbon raw materials and components is essential. Suppliers reliant on coal or gas may gradually become excluded.

Technology Shift Strategies

  • Switch to renewable-energy-based power sources
  • Adopt high-efficiency, low-emission production methods
  • Evaluate CCUS (Carbon Capture, Utilization & Storage)
  • Build real-time carbon monitoring infrastructure

6️⃣ FAQ — Frequently Asked Questions

Q1. Does CBAM start charging costs immediately?
A. Some sectors will face immediate costs, while others will be phased in. However, reporting and verification obligations begin right away, meaning companies unprepared now may face significant penalties or surging costs later.
Q2. Is the Korean government offering support?
A. Yes. Support measures include R&D funding, SME carbon-data platforms, consulting programs, tax incentives, and EU cooperation channels. The national carbon-data platform is expected to dramatically ease SME burdens.
Q3. What is the most practical way to reduce carbon emissions?
A. The most effective approaches include improving process efficiency, transitioning to low-carbon equipment, adopting electric-arc methods, and implementing energy-management systems. CCUS technologies may play a role in long-term strategies.
Q4. Does CBAM also affect SMEs?
A. Yes — even if SMEs do not export directly. Large corporations now require carbon-footprint data from suppliers, meaning SMEs lacking proper systems may struggle to maintain contracts.
Q5. Isn’t CBAM a violation of WTO rules?
A. The EU argues that CBAM is an environmental policy, making WTO challenges difficult. While concerns about fairness remain, major changes to the system are unlikely in the near future.

7️⃣ Conclusion & Outlook

CBAM presents both risks and opportunities for Korean manufacturers. Companies that move early on carbon reduction and process innovation may secure a competitive edge in the EU market.

The most critical factor now is carbon-management capability. Carbon is no longer just a cost — it is a core part of corporate competitiveness. Now is the time to reorganize your entire value chain into a low-carbon model.
