What is CBAM?

Carbon Border Adjustment Mechanism (CBAM) is the European Union''s mechanism for putting a carbon cost on the embedded emissions of certain imported goods.

It is intended to prevent carbon leakage—where production shifts from countries with stricter climate policies to countries with less stringent ones.

One-line definition for exam:

CBAM is an EU climate-trade instrument that seeks to equalise the carbon cost of certain imported goods with that faced by EU producers.

Which sectors are covered?

Initially, six sectors:

The EU''s definitive CBAM regime began on 1 January 2026.

The transitional period was 2023–2025, during which importers mainly reported embedded emissions; the definitive regime introduces financial obligations involving CBAM certificates.

Why is India concerned?

This is the most important UPSC angle.

India exports CBAM-covered products—particularly iron and steel—to the EU. The EU itself reported India among the major countries of origin for CBAM-covered imports.

India''s concerns

① Export competitiveness - If an Indian steel producer has relatively high embedded emissions, the EU importer may have to purchase more CBAM certificates, potentially making the Indian product less competitive.

② Developing-country concern - India has argued that developed countries should account for the different historical responsibilities and development needs of developing countries when designing climate-related trade measures.

③ Possible protectionism - India and other developing countries have raised concerns that climate measures at the border could function as trade barriers, even though the EU describes CBAM as a climate measure rather than a conventional tariff.

④ Measurement burden - Indian exporters need reliable systems to measure, report and verify embedded carbon emissions. The EU published detailed guidance in August 2026 specifically covering emissions calculations and verification for non-EU producers.

What is India''s response?

India has been developing its own Indian Carbon Market / Carbon Credit Trading Scheme (CCTS).

The CCTS framework was notified in 2023, with the Bureau of Energy Efficiency playing a key role in its implementation.

The basic idea is important:

India creates its own carbon-market mechanism → Indian industries reduce emissions → credible carbon pricing/credits → potentially better integration with international carbon markets.

Also remember:

CBAM is an EU mechanism; CCTS is India''s domestic carbon-market framework.

They are not the same scheme.

Why is CBAM in the news in 2026?

The big change

CBAM moved from the transitional phase to the definitive regime on 1 January 2026.

Under the definitive system, EU importers have obligations concerning embedded emissions and CBAM certificates. The certificate price is linked to the EU Emissions Trading System (EU ETS).

And importantly for India:

The EU–India trade agreement finalised in January 2026 did not remove CBAM. India and the EU agreed to continue technical discussions on carbon pricing, while the EU maintained the CBAM mechanism.

CBAM: Advantages vs Concerns

EU''s stated rationale

• Prevent carbon leakage
• Encourage cleaner production
• Create comparable carbon costs for EU and foreign producers
• Support EU climate targets

Concerns raised by India/developing countries

• Could increase costs for exporters
• May affect competitiveness of developing-country industries
• Creates significant measurement/verification requirements
• Raises questions about CBDR-RC — Common but Differentiated Responsibilities and Respective Capabilities
• Potential tension with principles of the multilateral trading system
