Bangkok, Thailand – The Asia Climate Summit 2025 featured a compelling panel discussion on the expanding global influence of the European Union’s Carbon Border Adjustment Mechanism (CBAM). Once perceived as a regional trade policy tool, CBAM is now reshaping the climate policy landscape far beyond Europe’s borders — prompting countries to reassess their carbon pricing strategies, industrial competitiveness, and diplomatic postures.
From Skepticism to Strategy
CBAM’s early reception outside the EU was marked by skepticism and a “wait-and-see” attitude. That stance is rapidly shifting. Many of the EU’s key trading partners are now moving from passive observation to active adaptation — implementing or strengthening domestic carbon pricing mechanisms, especially through Emissions Trading Systems (ETS), to mitigate potential trade impacts and align with emerging international norms.
A Catalyst for Domestic Carbon Markets
The panel emphasized CBAM’s catalytic effect in accelerating carbon pricing initiatives globally. In Asia, major economies like China, India, and Japan are advancing their ETS frameworks. China is expanding its system to include CBAM-relevant sectors such as cement, steel, and aluminum, alongside reforms in carbon accounting to increase international compatibility. India’s broader carbon market — initially focused on CBAM-targeted industries — is gaining momentum.
This trend is mirrored in other regions. Australia, the UK, and Brazil are exploring their own border carbon adjustments. In the Middle East, the UAE is assessing CBAM’s implications for its key export sectors — notably aluminum, steel, and fertilizers — with an eye toward decarbonization through clean energy. Meanwhile, Turkey’s long-delayed ETS plans are gaining traction, propelled by CBAM’s market signals.
The message was clear: CBAM is no longer just a European climate instrument. It is a global regulatory force influencing national climate policy decisions.
Balancing Environmental Ambition and Trade Fairness
From the EU’s standpoint, CBAM is a logical extension of its net-zero ambition. As the EU tightens its own ETS and phases out free allowances, CBAM serves to prevent carbon leakage by applying equivalent carbon pricing to imported goods — not to penalize trade partners, but to ensure fair competition. The cost, the EU asserts, will ultimately fall to European consumers.
Still, CBAM faces significant pushback, especially from developing economies. Critics argue that it undermines the principle of “common but differentiated responsibilities,” with concerns that CBAM could act as a de facto trade barrier. The policy’s unilateral nature — with the EU setting rules, collecting revenues, and deciding their use — has prompted diplomatic disputes, including WTO challenges and firm resistance from the BASIC countries (Brazil, South Africa, India, and China).
As full implementation looms in 2026, key challenges remain:
Recognition of Carbon Pricing Abroad: One unresolved issue is whether the EU will recognize carbon prices effectively paid in other jurisdictions. Transparent and comparable methodologies — potentially via Article 6 of the Paris Agreement — are essential for equitable treatment and revenue deduction.
Avoiding Global Fragmentation: With multiple countries designing their own border carbon mechanisms, there’s a rising risk of a fragmented landscape. Without interoperability or mutual recognition, businesses could face duplicative compliance and growing trade friction.
Ensuring Environmental and Economic Integrity: CBAM’s effectiveness will be tested by how well it addresses circumvention and maintains a level playing field as free allowances disappear. The risk of emissions simply shifting to downstream or excluded products remains a critical concern.
The panel underscored the need for stronger multilateral dialogue. Bilateral initiatives, such as the EU–UK plan to link their ETS systems, offer a glimpse of what coordinated frameworks could look like — reducing compliance burdens and enhancing climate ambition.
Conclusion: A Double-Edged Instrument
The discussion closed with a clear takeaway: CBAM is both a driver of global decarbonization and a source of political and economic complexity. Its ultimate success will depend not only on its environmental impact, but also on its ability to foster collaboration, ensure fairness, and avoid unintended trade distortions.
As the international climate policy arena evolves, CBAM stands as a symbol of the next phase: where climate ambition, trade, and diplomacy must be integrated — not isolated.
