Carbon border adjustment mechanism

Also called: CBAM, Border carbon adjustment · Topic: International Trade Policy, WTO and Intellectual Property · NCERT: Beyond NCERT

Meaning

A Carbon border adjustment mechanism (CBAM) is a charge on carbon-intensive imports. It equals the carbon price that domestic producers already pay, and it aims to stop carbon leakage. The European Union pioneered it under Regulation (EU) 2023/956.

It matters because it turns climate policy into a trade barrier. Indian exports of steel, aluminium, cement and fertiliser to the EU now face an extra cost based on how much carbon was released in making them.

Formula (simplified): CBAM cost = embedded emissions (tCO₂ per tonne) × [EU ETS price − carbon price already paid in the exporting country] During the phase-in, this cost is scaled down by the share of free allowances the EU still gives its own producers.

Explanation

Why CBAM exists: the carbon leakage problem

• Carbon leakage means emissions move to another country instead of being cut. Production shifts, or buyers start importing from countries with weaker climate rules.
• The chain inside the EU:
• EU producers pay a carbon price under the EU ETS (Emissions Trading System, a market where firms must buy permits for each tonne of CO₂ they emit).
• Their costs rise, so cheaper imports from countries with no carbon price win market share.

• Emissions stay the same globally, but EU jobs and output are lost.

• CBAM's fix: charge imports the same carbon price at the border. EU goods and foreign goods then compete on equal terms.

How it works: sectors, certificates and timeline

• Sectors covered (6): iron and steel, aluminium, cement, fertilisers, hydrogen and electricity.
• Embedded emissions are the CO₂ released while making a product. The importer must measure and report them.
• Timeline:
• Transitional phase, October 2023 to December 2025: importers only report embedded emissions. They pay nothing.
• Definitive regime from 1 January 2026: importers must buy CBAM certificates to cover those emissions.

• Certificate purchases are phased in slowly. At the same time, free EU ETS allowances to EU producers are phased out by 2034 (verify current).

• Why the two are linked: while EU firms still get free permits, charging importers in full would be unfair to them. So the CBAM charge rises only as free permits fall.

Worked example: why a home carbon price matters

• 1 tonne of Indian blast-furnace steel embeds 2.5 tCO₂.
• EU ETS price = €80/tCO₂. Carbon price already paid in India = €10/tCO₂.
• CBAM cost = 2.5 × (80 − 10) = €175 per tonne, before any phase-in reduction.
• If India had no carbon price: 2.5 × 80 = €200 per tonne.
• The lesson:
• The carbon price paid at home is deducted from the CBAM charge.
• So that money stays with India instead of going to the EU.
• The CBAM bill falls when (a) the exporting country's carbon price rises, or (b) the product is made with fewer emissions, for example scrap-based electric arc furnaces instead of blast furnaces.

In India

• Exports at risk:
• CBAM may raise the compliance burden on Indian steel exports to the EU. It may also add costs on fertiliser, aluminium and cement [1][2].
• It could reshape value chains, not only exports to the EU [1].
• MSMEs and secondary steel producers lack the tools to measure and document embedded emissions [2].

• Indian steel exporters already face high logistics costs, non-tariff barriers and safeguard duties (temporary extra import duties to protect a home industry from a sudden rise in imports). CBAM reporting adds to these [2].

• Government response:

• The Ministry of Steel held a Chintan Shivir (brainstorming meeting) on CBAM and AI in steel [1].

• India's domestic answer: Carbon Credit Trading Scheme (CCTS):

• Legal base: the Energy Conservation (Amendment) Act, 2022, in force from 1 January 2023 [4]. Section 14(w) of the EC Act, 2001 lets the Centre, in consultation with the Bureau of Energy Efficiency (BEE), specify a carbon credit trading scheme [5].
• CCTS notified on 28 June 2023 to create the Indian Carbon Market (ICM) [5][6]. It is overseen by the National Steering Committee for the Indian Carbon Market (NSC-ICM) [5].

• 9 compliance sectors: aluminium, chlor-alkali, cement, fertiliser, iron and steel, pulp and paper, petrochemicals, petroleum refinery and textiles [5][7]. These deliberately overlap with CBAM sectors.

• India–EU FTA (concluded 2026): CBAM provisions [3]:

• a forward-looking MFN assurance: any CBAM flexibility the EU gives a third country will also extend to India;
• technical cooperation on recognising India's carbon prices and Indian verifiers (the bodies that check emission data);
• financial and targeted support to help India cut emissions and meet the new rules.

Don't confuse with

• Carbon leakage: this is the problem, where emissions move abroad. CBAM is the tool meant to prevent it.
• EU ETS: this is the EU's internal carbon market for its own producers. CBAM applies the same carbon price at the border to imports.
• CCTS (India): India's domestic carbon market, notified in 2023. It is not a border charge. But carbon prices paid under it can be deducted from the CBAM bill.
• EU Deforestation Regulation (EUDR): also a green non-tariff barrier, but it asks for proof that goods (coffee, cocoa, rubber, soy, palm oil, wood, cattle) did not come from deforested land. It does not price carbon emissions.

Prelims Hooks

• EU CBAM's legal base is Regulation (EU) 2023/956.
• Six sectors: iron and steel, aluminium, cement, fertilisers, hydrogen and electricity. Trap: textiles and refineries are CCTS sectors, not CBAM sectors.
• Transitional phase (October 2023 to December 2025) = reporting only, no payment. Payment through CBAM certificates starts with the definitive regime from 1 January 2026.
• CBAM charge = embedded emissions × (EU ETS price − carbon price paid at home). A domestic carbon price reduces the charge.
• India's CCTS was notified on 28 June 2023 under the Energy Conservation (Amendment) Act, 2022. The nodal technical body is BEE [5][6].
• The India–EU FTA (2026) gives India a forward-looking MFN assurance on any CBAM flexibility the EU grants others [3].

Mains Points

• Climate tool or green protectionism?
• For the EU: it stops carbon leakage and puts EU and foreign producers on equal terms.

• India's objections:

  • it is unilateral, with rules set by the EU alone, outside the UNFCCC;
  • it goes against CBDR-RC (common but differentiated responsibilities and respective capabilities). Under this principle, rich countries caused most past emissions, so they should do more rather than tax poorer countries' exports;
  • it acts as green protectionism, meaning climate rules used as a hidden trade barrier;
  • it hits steel and aluminium, for which the EU is a major market.

• India's three-part response (GS-III):

• build a domestic carbon price (CCTS), so the revenue stays in India;
• use FTA safeguards: the India–EU FTA's MFN assurance and recognition of Indian carbon prices [3];

• decarbonise steel through green hydrogen and scrap-based EAF (electric arc furnace).

• The MSME challenge: measuring and documenting embedded emissions is costly for small and secondary steel producers [2]. India needs low-cost measurement systems, accredited Indian verifiers and targeted finance. Otherwise, CBAM could push small exporters out of EU value chains [1].
