Introduction

The European Union is preparing to take a significant next step in its climate and trade policy by expanding the scope of its Carbon Border Adjustment Mechanism, commonly referred to as CBAM. According to draft policy proposals, the European Commission intends to include a broader range of imported products under the carbon border levy, extending beyond the initial focus on raw materials such as steel, cement, aluminum, fertilizers, electricity, and hydrogen. The proposed expansion reflects the EU’s determination to close regulatory gaps, strengthen its climate ambitions, and prevent carbon leakage as global trade adapts to stricter environmental standards.

Understanding The Carbon Border Adjustment Mechanism

The Carbon Border Adjustment Mechanism was developed as part of the European Union’s wider climate strategy to reduce greenhouse gas emissions and reach climate neutrality by 2050. Within the EU, industrial producers are required to pay for their emissions under the Emissions Trading System, which places a price on carbon and incentivizes companies to reduce pollution. However, this system also creates the risk that production may move to countries with weaker environmental regulations, a phenomenon known as carbon leakage.

CBAM was designed to address this challenge by imposing a carbon cost on imported goods equivalent to what EU producers pay domestically. Importers must report the embedded emissions associated with their products and purchase carbon certificates corresponding to those emissions. The mechanism ensures that imported goods do not enjoy an unfair cost advantage over EU-made products simply because they are produced in jurisdictions with lower environmental standards.

Initially, CBAM focused on sectors considered most vulnerable to carbon leakage and most emissions-intensive. However, as implementation planning progressed, policymakers identified potential loopholes that could undermine the system’s effectiveness. The proposed expansion is intended to address these vulnerabilities.

Why Does The EU Want To Expand The Scope?

The draft proposal to widen CBAM reflects concerns that limiting the mechanism to raw materials alone could encourage manufacturers to shift production strategies in ways that avoid carbon costs. For example, instead of exporting steel to the EU, a foreign producer might export finished products such as machinery or appliances that contain steel but fall outside the original CBAM scope. This would allow emissions-intensive production to continue without being subject to the carbon levy.

To counter this risk, the European Commission is considering extending CBAM to cover additional products including car parts, household appliances like refrigerators and washing machines, construction materials, power transformers, electrical cables, and farming machinery. These goods often rely heavily on carbon-intensive materials and manufacturing processes, making them relevant from a climate accounting perspective.

Economic And Industrial Implications

The proposed expansion of the carbon border levy is expected to have wide-ranging economic implications for both EU and non-EU industries. Importers of newly covered products would face additional administrative and financial obligations, including emissions reporting and the purchase of carbon certificates. For some manufacturers, particularly those operating in regions with high carbon intensity, this could increase production costs and reduce price competitiveness in the European market.

At the same time, EU policymakers argue that the measure could drive positive change by encouraging cleaner production practices globally. Exporters seeking to maintain access to the EU market may invest in energy efficiency, cleaner technologies, or lower-carbon inputs to reduce their exposure to the levy. Over time, this could contribute to global emissions reductions, aligning trade incentives with climate objectives.

Within the EU, some of the revenue generated by the expanded carbon border levy may be used to support domestic industries that face higher costs due to the transition to low-carbon production. Draft proposals suggest that a portion of CBAM revenues could be allocated to help EU manufacturers invest in emissions reduction technologies, provided they demonstrate clear commitments to decarbonization. This approach aims to balance competitiveness concerns with climate goals.

Revenue Use And Policy Design Challenges

The expansion of CBAM could generate substantial public revenue over the coming years. Estimates suggest that by the end of the decade, revenues could reach several billion euros, depending on carbon prices, trade volumes, and the final list of covered products. How these funds are used will be a critical policy question.

European policymakers are exploring options to use CBAM revenues to support the green transition, including funding industrial decarbonization, innovation, and infrastructure. However, the design of such support mechanisms must navigate complex legal constraints, particularly international trade rules. Providing direct rebates or export subsidies to EU companies could raise concerns about compliance with global trade agreements, which generally restrict measures that distort competition.

Global Trade And Diplomatic Reactions

The EU’s carbon border policy has already drawn attention and criticism from several major trading partners. Countries with export-oriented industries have expressed concern that the expansion of CBAM could function as a trade barrier, disproportionately affecting developing and emerging economies. Some governments argue that while climate action is essential, unilateral measures risk fragmenting global trade and placing undue burdens on countries with fewer resources to transition quickly.

There are also concerns about administrative complexity. Accurately measuring and verifying embedded emissions across diverse manufacturing processes can be challenging, particularly for smaller exporters. Without adequate support or clear guidance, compliance costs could become a significant obstacle to market access.

In response, the EU has emphasized that CBAM is intended to be non-discriminatory and compatible with international trade rules. The mechanism applies equally to domestic and foreign producers and is based on objective emissions data rather than country of origin. EU officials also argue that CBAM could encourage greater international cooperation on carbon pricing and climate standards over time.

Legal Considerations And WTO Compatibility

Ensuring that the expanded carbon border levy complies with international trade law is one of the most complex aspects of the proposal. The EU maintains that CBAM is consistent with global trade rules because it mirrors domestic carbon pricing and does not favor local products over imports. The mechanism is framed as an environmental measure aimed at addressing climate change rather than a protectionist tool.

However, legal challenges remain a possibility, particularly if trading partners perceive the policy as discriminatory or overly burdensome. The inclusion of compensation measures for EU industries could also attract scrutiny if they are seen as indirect subsidies. To minimize legal risks, the EU is expected to emphasize transparency, uniform application, and clear methodologies for emissions calculation.

Implementation Timeline And Next Steps

The draft proposal to expand CBAM is still subject to political negotiation within the European Union. It must be formally presented, debated, and approved by both the European Parliament and the Council, representing EU member states. During this process, details such as product coverage, reporting requirements, revenue use, and transitional arrangements may be revised.

If adopted, the expanded scope would likely be implemented in phases, aligned with the full introduction of carbon payments under CBAM starting in 2026. Businesses affected by the new rules will need time to adapt their reporting systems, supply chains, and production methods. Policymakers are expected to consider transitional measures to ease the adjustment, particularly for smaller firms.

Conclusion

The European Union’s plan to expand its carbon border levy marks a decisive step in integrating climate policy with global trade. By extending CBAM to additional products, the EU aims to close loopholes, protect the integrity of its carbon pricing system, and reinforce its commitment to reducing global emissions. The proposal highlights the growing recognition that climate responsibility must extend across entire value chains, not just at the point of raw material production.

At the same time, the expansion introduces significant economic, legal, and diplomatic challenges. Its success will depend on careful policy design, international engagement, and clear implementation frameworks that balance environmental ambition with fairness and competitiveness.
