This study examines the impact of carbon neutrality policies on Korea and explores potential government responses to the rapidly evolving global policy landscape concerning carbon and trade. Specifically, it focuses on the European Union’s Carbon Border Adjustment Mechanism (CBAM) and how South Korea's carbon neutrality policies might influence the CBAM's impact. In addition, it analyzes the effects of each carbon neutrality policy option on Korea’s economy, including trade and GDP, and emissions.

This study finds that the EU CBAM may not affect Korean exports due to its relatively narrow scope of products and emissions covered in the current version of the policy. However, its influence is likely to grow if the scope of regulated products expands and the range of indirect emissions covered increases. The study then considers carbon pricing, green technology R&D, and green supply chain policies as strategic directions for Korea's government to both respond to global policy changes, such as CBAM, and achieve climate neutrality. Although both increasing carbon prices and developing carbon reduction technologies mitigate the negative impacts of CBAM by decreasing CBAM tariff rates, their effects on Korea's production, exports, income, and welfare differ.

Green supply chain policies involve adjusting trade costs according to the carbon intensity and price of intermediate inputs’ origins. This aims to reduce production's embedded indirect emissions and increase the carbon price already paid in source countries. The study evaluates two opposing approaches to implementing this policy: lowering trade costs for 'green' suppliers and raising them for 'dirty' suppliers. The results indicate that decreasing trade costs, as opposed to increasing them, results in higher GDP, greater export competitiveness, and improved welfare. The study shows that although different policy options are themselves effective in responding to CBAM and reducing carbon emissions in Korea overall, their impact on Korea’s economy and emissions are heterogeneous. Therefore, understanding the complex consequences of these policies and selectively implementing them based on the distinct characteristics of the affected industries is crucial.
