A new study suggests the EU’s carbon border levy could encourage trading nations to adopt their own carbon pricing, amplifying global emissions reductions beyond Europe’s borders.
The European Union’s carbon border levy could do more than shield heavy industry from cheaper, high-emission imports. A new academic study suggests it may also encourage trading partners to adopt their own carbon prices, amplifying the bloc’s climate impact well beyond Europe’s borders.
The research, published in the Journal of the Association of Environmental and Resource Economists and led by the Potsdam Institute for Climate Impact Research, models how the EU’s Carbon Border Adjustment Mechanism could reshape international climate policy. The mechanism, which began extending the EU’s domestic carbon price to imports in early 2026, currently covers steel, iron, aluminium, cement, fertilisers, electricity and hydrogen.
According to the authors, countries exporting into the EU face a choice: pay the border charge or introduce their own carbon pricing and effectively join a wider climate coalition. The study argues that this dynamic can create incentives for policy diffusion, especially for economies already deeply integrated into European supply chains.
Timothé Beaufils, the study’s lead author, said the mechanism is meant to help European industry decarbonise without losing competitiveness, but that its effects outside the bloc are equally important. Leonie Wenz, a co-author at PIK, said the findings support the idea of a Brussels effect, in which rules set in the EU spill over into other jurisdictions.
Using a model that combines trade economics and game theory, the researchers simulated trade flows across 56 sectors and 43 countries. They assumed an EU carbon price of $100 per tonne and found that, without a border adjustment, emissions cuts inside the bloc would be partly undone by higher emissions elsewhere. In that scenario, EU emissions fall by 505 million metric tonnes a year, but global cuts amount to only 305 million tonnes because production shifts abroad and lower global prices encourage additional fossil fuel use.
With the border adjustment in place, leakage falls sharply. The study says the share of avoided emissions offset outside the EU drops from 40% to 15%, lifting the global reduction to 399 million tonnes.
The strongest result comes when trading partners respond by introducing their own pricing systems. In that case, the model shows global emissions falling by 691 million tonnes a year, 73% more than under EU policy alone. Canada, Japan, South Korea and Taiwan emerge as the most likely candidates to join such a coalition in order to avoid the additional burden of the EU levy.
The OECD has previously said CBAM is designed to curb carbon leakage by aligning the carbon costs faced by foreign producers with those borne by EU competitors. It has also warned that, without such a measure, some emissions reductions achieved in Europe can be partly displaced overseas.
The new study suggests the diplomatic and industrial implications could be broader still. It finds that extending CBAM to additional sectors would strengthen the incentive for more countries to adopt carbon pricing, including potentially the United States. China, by contrast, would only be expected to join under a much lower carbon price.
The authors caution that the precise numbers depend on model assumptions, but say the central conclusion is robust: the EU’s border carbon policy could help push other economies towards stronger climate action at a time when international negotiations remain slow.

- https://www.oecd.org/en/blogs/2025/03/eu-carbon-border-adjustment-mechanism-what-is-it-how-does-it-work-and-what-are-the-effects.html – This OECD blog post examines the European Union’s Carbon Border Adjustment Mechanism (CBAM), which aims to prevent carbon leakage by aligning the carbon costs of foreign producers with those of EU producers within the EU market. It estimates the impact of CBAM on global carbon emissions and European production, highlighting that without CBAM, for every ton of CO₂ emissions avoided within the EU, approximately 0.19 tons of emissions would leak overseas. The post discusses how CBAM seeks to address this issue by imposing a carbon price on imported goods, thereby encouraging other countries to adopt similar carbon pricing measures.

It discusses how CBAM aims to level the playing field between EU and non-EU producers by imposing a carbon price on imported goods, thereby preventing carbon leakage and encouraging other countries to adopt similar carbon pricing measures. The brief also outlines the sectors initially covered by CBAM and the expected timeline for its implementation, offering insights into the broader implications for global trade and climate policy.

The article examines how CBAM will affect global trade, particularly focusing on countries like Canada, South Africa, Brazil, and Turkey, which are expected to be significantly impacted due to their high levels of exports to the EU. It discusses the implications of CBAM on these countries’ economies and the broader global trade landscape, highlighting the need for strategic responses to mitigate potential adverse effects.

Using a global computable general equilibrium model, the study simulates various scenarios to assess the effects of CBAM on industry output, export and import flows, carbon emissions, and trade balances. The findings indicate notable variations among the three countries, with China experiencing a marked drop in export and import demand, likely leading to a decrease in domestic output. The study recommends addressing the CBAM carbon tax through national mitigating policies and enhanced cooperation among Korea, China, and Japan.

Using a global, multisector, computable-general-equilibrium model and the GTAP database, the study evaluates the potential economic impacts of CBAM. The findings suggest that CBAM could have significant effects on trade flows, industry output, and carbon emissions in the affected countries. The study emphasizes the need for these countries to develop strategies to mitigate the potential adverse effects of CBAM on their economies.
- https://pubmed.ncbi.nlm.nih.gov/38396180/ – This study, published in the journal Environmental Science and Pollution Research, examines the impact of the EU’s Carbon Border Adjustment Mechanism (CBAM) on the global iron and steel trade and emission reduction. The research analyzes how CBAM, which imposes a carbon price on imported goods, affects the international trade dynamics of the iron and steel industry and its potential to reduce global carbon emissions. The findings suggest that CBAM could lead to significant changes in trade patterns and contribute to emission reductions, highlighting the importance of considering such mechanisms in global climate policy.
