Carbon Border Adjustment Mechanism (CBAM) — UPSC Notes

The EU’s Carbon Border Adjustment Mechanism (CBAM) is arguably the most consequential climate-trade instrument of the 2020s. It taxes embedded carbon in imports of carbon-intensive goods entering the EU, starting definitively in 2026. For India — whose steel and aluminium exports to the EU run into billions of dollars — the CBAM is simultaneously a climate challenge and a trade policy threat. For UPSC, CBAM sits at the intersection of environment (GS-III), international relations (GS-II), and economy.

What is CBAM?

The problem: carbon leakage

• When the EU tightens its own carbon policies (e.g., through EU ETS, making emissions costly), energy-intensive EU producers face higher costs.
• Carbon leakage occurs when:
• Companies relocate production to countries with laxer climate rules, or
• EU products are replaced by more carbon-intensive imports.
• Net effect: global emissions don't fall; they simply shift.

CBAM as a carbon tariff

The EU's response: charge imports from third countries a carbon levy equivalent to what EU producers pay under the EU ETS. This is meant to:

• Level the playing field for EU producers.
• Prevent carbon leakage.
• Incentivise foreign producers to decarbonise.
• Protect EU's climate ambition under the European Green Deal and "Fit for 55" package.

How CBAM works

Covered sectors (initial list)

Cement, iron and steel, aluminium, fertilisers, electricity, hydrogen — chosen because they are carbon-intensive and at highest risk of leakage.

Timeline

CBAM certificate pricing

Certificates are priced at the weekly average EU ETS auction price (roughly €70-100 per tonne in 2024).

Credits for third-country carbon pricing

If the exporter has already paid a carbon price in its home country, that amount can be deducted. Domestic carbon pricing in the exporting country thus reduces CBAM cost.

Merits of CBAM (EU view)

Preventing carbon leakage

• Directly addresses the leakage problem.
• Reduces outsourcing of pollution to countries with weaker policies.

Protecting EU industry

• EU producers subject to EU ETS will not be unfairly undercut by non-EU imports.

Aligning with EU Green Deal

• Supports EU's climate neutrality by 2050 and the 55% emissions cut by 2030 target.

Raising global ambition

• Foreign producers will have incentive to decarbonise or risk losing EU market.

Revenue generation

• CBAM revenues estimated at €1-10 billion/year — potential source for EU own resources and climate finance.

Issues with CBAM — India's concerns

1. Industrial interests

• In FY2022, India exported ~USD 10 billion of steel and aluminium products to the EU.
• CBAM could add an effective 20-35% price burden on these exports versus ~2-3% average EU duties on domestic producers.
• Could seriously affect Indian steel, aluminium, cement, fertiliser exporters.

2. CBDR violation

• CBAM applies equally to all non-EU exporters, ignoring the Common But Differentiated Responsibilities and Respective Capabilities principle of UNFCCC.
• Developing countries with low historical cumulative emissions are penalised.
• Particularly unfair to developing countries whose per-capita emissions are a fraction of developed countries'.

3. Green protectionism

• Critics argue CBAM is disguised trade protectionism.
• Differences between effective CBAM charge (~20-35%) and EU domestic carbon cost (~2-3% passthrough) raise WTO concerns.

4. Valuation of embedded carbon

• Methodologies for calculating embedded emissions vary.
• Indian producers may face higher default values in absence of verified data — a reporting-cost burden.

5. Historic responsibility

• Developing countries contributed least to historic emissions; CBAM ignores this.

6. Free Trade Agreements

• If India signs an FTA with EU, the CBAM applicability is ambiguous. India might lose tariff protection on EU imports without CBAM reciprocity.

7. WTO compatibility

• WTO law permits non-discriminatory environmental measures (Article XX GATT). CBAM's selective coverage and default values raise MFN and national treatment concerns.
• India, China, South Africa, Brazil (BASIC) have challenged CBAM's legitimacy at the UNFCCC.

India's response

Domestic carbon pricing

• Carbon Credit Trading Scheme (CCTS) notified 2023 — reduces CBAM exposure by creating domestic carbon price.
• PAT scheme integration into CCTS.

Negotiating with EU

• Seeking exemption or reduced rates for Indian manufacturers, particularly SMEs and iron-steel sector.
• Requesting recognition of India's NDCs and climate actions.

Decarbonising industry

• Green Steel Policy (2024) — guidelines for hydrogen-reduced steel.
• Green Hydrogen Mission (2023).
• Renewable energy scale-up to lower embedded carbon in industry.
• CCUS pilot projects.

Independent carbon tax (commerce minister's proposal)

• India's own carbon tax to protect manufacturing sector — would be deductible under CBAM.

Trade diversification

• Reducing over-reliance on EU market; diversifying to Global South partners.

Multilateral challenge

• Raising CBAM at WTO, UNFCCC, G20 forums.
• India hosted dialogues during its G20 presidency (2023).

Similar instruments elsewhere

• UK CBAM — announced for 2027.
• US Clean Competition Act proposals.
• Canada, Australia exploring similar mechanisms.

CBAM is likely to be replicated globally — creating a network of carbon-border policies and shaping post-2025 trade patterns.

Latest developments (2024-26)

Updated context: verify with EU Commission, GoI commerce ministry, CBAM registry.

• CBAM transitional phase — quarterly reports required; significant compliance burden for Indian exporters.
• CCTS operational — first compliance cycle 2025-26.
• EU-India trade negotiations — CBAM remains a sticking point in FTA talks.
• COP29 — BASIC countries criticised CBAM again; no UNFCCC resolution.
• India considering retaliatory tariffs or carbon-equivalent trade measures.
• Green Steel Policy 2024 — BEE notified standards for low-emission Indian steel.

UPSC relevance

GS-III mapping

• Environment; climate change.
• Economy — industrial competitiveness, exports.

GS-II overlap

• International relations — India–EU.

Prelims bullets

• CBAM — Carbon Border Adjustment Mechanism.
• Part of EU Green Deal / Fit for 55 package.
• Covers: cement, iron/steel, aluminium, fertilisers, electricity, hydrogen.
• Transitional phase: Oct 2023 – Dec 2025.
• Definitive phase: from 1 January 2026.
• CCTS — India's Carbon Credit Trading Scheme.

Mains angles

• "Analyse the EU's Carbon Border Adjustment Mechanism and its implications for India's export economy and climate diplomacy."
• "Is CBAM consistent with the UNFCCC principle of CBDR? Examine."
• "Discuss India's strategies to mitigate the impact of CBAM on its industries."

Essay hooks

• Trade and climate — the 21st-century fault line.
• CBAM as green protectionism or climate leadership?
• India's balancing act — defending exports while greening industry.

Quick revision

Bottom line for UPSC: CBAM is the first major attempt to internalise carbon in international trade — arguably necessary for climate integrity, but problematic under CBDR. India's response must combine domestic decarbonisation, multilateral advocacy, and negotiated exemptions.
