The Emergence of Unilateral Carbon Trade Barriers

The European Union (EU) will fully implement the Carbon Border Adjustment Mechanism (CBAM) starting January 2026. This system requires importers of carbon-intensive products to bear carbon costs equivalent to those of EU domestic products, targeting six key industries: steel, aluminum, cement, electricity, fertilizers, and hydrogen.

The problem is that this measure is being implemented unilaterally without prior consultation with the World Trade Organization (WTO) or trading partners. EU importers must purchase certificates corresponding to the carbon emissions of these products, and these costs are likely to be passed on to exporters in developing countries.

Burden Concentrated on Developing Countries

According to a research report published last month by the International Monetary Fund (IMF), while CBAM's impact on the gross domestic product (GDP) of Middle Eastern and Central Asian countries is limited, the blow to specific industries such as steel and fertilizers is severe.

While the system ostensibly aims to address climate change and protect EU domestic producers, it actually functions as an additional trade barrier for developing countries. Producers in developing countries must bear additional costs for disclosing carbon emission information and face pressure to rapidly transform their production methods.

The Paradox of Climate Justice

Nobel Economics Prize laureate Esther Duflo explains this through the concept of 'moral debt'. Despite developed countries being the main culprits of the climate crisis, they maintain consumption patterns while merely relocating production to developing countries, yet impose additional costs on developing country products.

The UN Framework Convention on Climate Change has reached international consensus on 'Just Energy Transition'. However, CBAM is a unilateral measure that bypasses such multilateral agreements, showing the contradiction of reduced financial support for industrial transition in developing countries while trade restrictions are strengthened.

CBAM's Mechanism and Problems

Revenues from carbon certificates purchased by EU importers under CBAM are incorporated into the EU budget and used to support domestic producers. This is essentially a structure that subsidizes EU industry at the expense of developing country producers.

Furthermore, the WTO has not yet made an official determination on whether CBAM complies with international trade rules. While the EU claims it is compatible with WTO regulations, it will take considerable time to demonstrate actual damages. In the meantime, exporters in developing countries and their national economies must bear substantial losses.

Fragmentation of Global Trade Order

CBAM is likely to have long-term impacts on the global trade order beyond being a simple environmental measure. Unilateral measures risk deepening the fragmentation of international trade, increasing trade disputes, and further widening the gap between strong and weak parties.

Developing countries struggle to secure funds needed for production facility conversion amid limited fiscal capacity. With international concessional finance support also declining, structural transformation is becoming even more difficult.

Future Outlook [AI Analysis]

The implementation of CBAM is likely to make the international trade environment more complex. If other developed countries introduce similar systems, the export competitiveness of developing countries could weaken overall.

Meanwhile, as developing countries' resistance to such unilateralism grows, there are concerns that multilateral climate and trade negotiations may reach a deadlock. A new international framework that simultaneously realizes climate justice and trade justice is needed.

Developing countries are expected to seek multifaceted response strategies, including strengthening regional cooperation and utilizing WTO dispute settlement procedures to address CBAM.
