As the European Union's Carbon Border Adjustment Mechanism (CBAM) approaches its full implementation in 2026, it is emerging as a key topic in global economics and climate policy. This system imposes tariffs on the carbon emissions embedded in products imported into the EU, driven by two main goals: addressing climate change and ensuring competitiveness. Major trading partners, including South Korea, are accelerating their efforts to analyze the potential impact of this system on their economies and business environments, and to formulate countermeasures. CBAM entered a transitional period in October 2023, requiring importers to report carbon emissions, and will move into a full implementation phase in 2026, entailing actual financial burdens. The initial scope of application covers carbon-intensive industrial products such as steel, cement, aluminum, fertilizers, electricity, and hydrogen. The scope is expected to gradually expand thereafter and will operate in conjunction with the EU Emissions Trading System (ETS). To understand the introduction of CBAM, it is necessary to examine the history of EU climate policy. Over the past few decades, the European Union has set sustainable development and environmental protection as key policy objectives. In particular, the European Green Deal is a landmark plan that clearly outlines the long-term goal of achieving carbon neutrality by 2050. In line with this plan, the EU has introduced several phased measures, and CBAM is a continuation of these environmental policies. The core of CBAM is to prevent carbon leakage and enhance fairness. Carbon leakage refers to the phenomenon where companies sensitive to greenhouse gas emissions relocate their production bases to countries with less stringent carbon regulations. This not only diminishes the effectiveness of the EU's internal climate policies but also raises concerns that it could weaken global decarbonization efforts. Therefore, CBAM serves as a type of environmental tariff designed to prevent goods produced outside the EU from entering the European market cheaply by circumventing strict European emission regulations. Its purpose is to prevent unfair competition by applying the same standards across all countries and to promote compliance with environmental obligations. A report by the Clingendael Institute, titled 'Why European Industry Needs Carbon Diplomacy in the CBAM Era,' published on April 27, 2026, assessed that CBAM will help EU domestic industries and external suppliers compete under the same standards and will serve as a key tool to promote global decarbonization. The report emphasizes that CBAM is essential not only for preventing carbon leakage but also for encouraging partner countries to adopt their own carbon pricing policies, thereby aligning international trade with the EU's climate goals. This analysis suggests that the EU's move is not merely protectionism aimed at safeguarding its own borders, but a strategic effort to promote global sustainability. The Clingendael report particularly highlights the importance of 'carbon diplomacy.' It suggests that instead of unilaterally imposing regulations through CBAM, the EU should establish mutually recognizable carbon pricing mechanisms through dialogue with key trading partners. This approach is presented as a way to accelerate global decarbonization while minimizing trade friction. The report argues that EU industries, in cooperation with governments, should lead carbon policy cooperation with third countries, and that this is the path to maintaining the long-term competitiveness of European industry. However, there is also debate about the economic repercussions of CBAM. AllianceBernstein, in its analysis 'Carbon Emission Regulations Could Redefine Corporate Strengths' dated April 29, 2026, predicted that carbon regulations would increase cost burdens for individual companies, clearly distinguishing 'winners and losers' in the process. Specifically, this analysis raises concerns that if free allowances within the EU Emissions Trading System (ETS) gradually decrease while CBAM tariffs simultaneously increase, domestic producers might actually become competitively disadvantaged compared to external producers. According to AllianceBernstein's analysis, when CBAM is fully implemented, EU domestic companies could face a double burden. On one hand, the cost of purchasing emission allowances under the ETS will increase, and on the other hand, while CBAM tariffs will raise costs for external competitors, if the coordination between these two mechanisms is not perfect, unexpected competitive distortions could arise. This suggests that how to bridge the gap between the policy ideal of encouraging global decarbonization and market realities will be a critical variable for policy success. Once CBAM is fully implemented, many countries whose economies heavily rely on exports to the EU are likely to face its direct impact. In South Korea's case, the steel, chemical
