EU’s Carbon Border Adjustment Mechanism (CBAM)

Why in News?

The Government of India is reportedly preparing a scheme to bear 90% of the compliance cost incurred by MSMEs exporting to the European Union under the Carbon Border Adjustment Mechanism (CBAM).

What is CBAM?

CBAM is an EU mechanism designed primarily to address carbon leakage. Carbon leakage occurs when production shifts to countries with less stringent climate policies, or when European products are replaced by more carbon-intensive imports.

It complements the EU’s Emissions Trading System (EU ETS). While the EU ETS puts a carbon price on emissions from covered activities within Europe, CBAM seeks to ensure that imported goods also reflect the carbon emissions generated during their production. The EU states that the mechanism is designed to be compatible with WTO rules.

CBAM is therefore different from a conventional customs tariff. Its liability is linked to the embedded emissions of covered products rather than simply their monetary value.

How Does CBAM Work?

During the transitional phase, importers mainly had to report the embedded emissions of covered goods. Since 1 January 2026, financial obligations have been introduced under the definitive regime.

EU importers crossing the applicable threshold must obtain authorised CBAM declarant status, report the embedded emissions of imported goods and surrender the required number of CBAM certificates. The certificate price is linked to EU ETS allowance prices. For 2026, it is based on a quarterly average of EU ETS auction prices, while from 2027 it will use a weekly average.

Where a carbon price has already been paid in the country of production, the corresponding amount can be deducted. This is intended to prevent the same emissions from being charged twice.

Which Products are Covered?

CBAM currently covers six carbon-intensive sectors:

• Iron and steel
• Aluminium
• Cement
• Fertilisers
• Electricity
• Hydrogen

These sectors were selected because of their significant emissions and exposure to carbon-leakage risks. The EU is also examining changes to broaden CBAM coverage, particularly for certain downstream products, reflecting concerns that companies could otherwise avoid the mechanism by exporting processed products rather than basic materials.

Why is CBAM Important for India?

CBAM has direct implications for India because iron and steel and aluminium exports are among the products covered by the mechanism. India was also among the major countries of origin for CBAM-covered imports recorded when the definitive system entered into operation in January 2026.

For Indian exporters, the challenge is not limited to the potential financial cost. They increasingly need reliable systems to measure, report and verify emissions at the production stage. Companies with cleaner production processes and credible emissions data may be better placed to manage the new requirements, while smaller firms may face higher compliance costs.

The issue of verification has consequently become important. In August 2026, the European Commission issued detailed guidance on the verification and accreditation of CBAM emissions data, with the verification system being progressively operationalised during 2026-27.

Implications for India’s Economy

CBAM could increase the cost of Indian carbon-intensive exports to the European market, particularly where production involves relatively high emissions. This may affect the competitiveness of Indian firms and could encourage exporters to redirect some products towards other markets.

At the same time, CBAM creates an incentive for Indian industries to invest in energy efficiency, renewable energy, cleaner technologies and low-carbon production. In sectors such as steel, the transition towards cleaner production methods could therefore become important not only for meeting climate goals but also for maintaining access to major export markets.

The impact will also extend to Indian MSMEs, which may have fewer financial and technical resources for emissions measurement, certification and technological upgrades.

CBAM and India-EU Trade Relations

CBAM has become an important issue in the broader India–EU economic relationship. The EU is one of India’s major trading partners, and European environmental regulations are increasingly influencing the conditions under which Indian products access the European market.

This means that traditional tariff negotiations are no longer sufficient to understand international trade. Carbon standards, environmental regulations, traceability and emissions verification are becoming important components of market access.

For India, engagement with the EU on technical standards, verification procedures, carbon accounting and recognition of domestic efforts to reduce emissions will therefore be important.

WTO and Climate Justice Debate

CBAM has also generated a wider debate over the relationship between trade rules and climate action. The EU argues that CBAM prevents carbon leakage and places imported and domestic producers on a comparable carbon-cost footing. Developing countries, however, have raised concerns about the implications of such measures for their exports and development prospects.

The debate also connects with the principle of Common but Differentiated Responsibilities and Respective Capabilities (CBDR-RC) under the international climate regime. Developing countries have historically contributed less to cumulative emissions and often face greater financial and technological constraints in shifting towards low-carbon production.

Thus, the challenge is to reconcile climate ambition with a trading system that takes differences in development and technological capacity into account.

Conclusion

CBAM represents a major shift in the global trading environment, where carbon intensity is increasingly becoming a factor in market access. For India, it presents both an export challenge and an incentive to accelerate industrial decarbonisation. Its significance therefore extends beyond Europe to the future of global trade, climate diplomacy and India’s economic competitiveness.
