EU’s Carbon Border Adjustment Mechanism (CBAM) & its Global Implications

In July 2025, BRICS nations including India condemned and rejected the EU’s Carbon Border Adjustment Mechanism (CBAM) and similar measures, warning they undermine developing countries’ clean-energy transitions. The EU’s CBAM is a kind of carbon tariff on imported carbon-intensive goods (such as steel, cement and aluminium) that forces high-emission exports to Europe to pay the same carbon price as EU products. Critics say such policies could unfairly penalize India and other developing exporters. By equating import carbon costs with those paid domestically, CBAM has sparked debates over climate justice and trade fairness.

What exactly is the EU CBAM and how is it defined?

• The EU’s Carbon Border Adjustment Mechanism (CBAM) is a levy on imports of select carbon-intensive goods to equalize carbon costs between foreign producers and EU manufacturers. Covered products include heavy-industry materials like steel, cement, aluminium, fertiliser, electricity and hydrogen.
• EU importers of these goods must report the embedded carbon emissions of each import. From 2026 onward, they must buy CBAM certificates (at the EU’s carbon price, around €75–100 per tonne CO₂) for each tonne of CO₂ in the imported goods, unless the exporter can prove that carbon was already priced abroad (in which case the corresponding cost is deducted).
• Key features:
  • Covers ~303 product categories in key industrial sectors.
  • Fees expressed in €/tonne CO₂, matching the EU carbon price.
  • Phases: reporting-only (2023–2025) followed by full implementation in 2026.
• The mechanism is designed to be WTO-compliant by treating imports the same as domestic products for carbon pricing. It effectively extends the EU Emissions Trading System (ETS) price to imported goods.

Why did the EU introduce the CBAM and what issues does it address?

• To prevent carbon leakage: Without CBAM, EU factories under strict emissions rules might lose market share to foreign competitors in countries with laxer climate policies. By taxing carbon on imports, CBAM discourages relocating production purely to avoid carbon costs.
• To ensure fair competition: It aligns the cost of carbon for imports with that for EU-made products. This protects EU industries (like steel and cement) by removing any price advantage from dirtier imports, while still allowing consumers access to imported goods.
• To reinforce climate goals: Pricing carbon at the border encourages producers worldwide to decarbonize. CBAM is part of the EU Green Deal’s push to meet targets (e.g. 55% emission cut by 2030) by covering emissions embodied in trade.
• As the EU imports about 15% of global goods, CBAM significantly broadens the scope of carbon pricing. Proponents argue it creates a global incentive for cleaner production without relying on every trading partner to impose its own carbon tax.

When was CBAM enacted and what is its implementation timeline?

• Proposal and adoption: CBAM was first proposed in 2021 and formally approved by the EU Parliament and Council in 2023.
• Transitional phase (2023–2025): From October 1, 2023, EU importers began collecting and reporting carbon emissions data for covered imports. During this phase no CBAM payments are due; it serves as a trial and data-gathering period.
• Definitive phase (2026 onwards): From January 1, 2026, the full CBAM regime comes into effect. EU importers must purchase CBAM certificates at the EU carbon price according to their reported emissions. This is when the actual carbon tariff is paid.
• The EU will review CBAM’s performance in 2025 and plans to expand the list of covered goods gradually. By 2030, more sectors may be added to ensure CBAM covers the majority of emissions in traded industries.

Where does the EU CBAM apply and which goods are covered?

• CBAM applies at the EU customs frontier: it affects any covered goods imported from outside the EU. Goods produced within the EU (already covered by the ETS) are not subject to CBAM.
• Covered products: Initially, CBAM targets specific carbon-intensive goods in sectors at risk of carbon leakage (steel and iron, cement, aluminium, fertilisers, electricity and hydrogen). In total ~303 product codes are in scope.
• Geographic reach: It impacts exporters globally to the EU market. Major affected exporters include India, China, Russia, Turkey and others that supply large quantities of covered goods to Europe. For example, around 25% of India’s steel exports go to the EU.
• Certain imports are excluded: for instance, electricity from EU offshore wind farms (considered EU-origin) or products already priced under equivalent carbon rules. CBAM strictly taxes third-country goods entering the EU market.

Who implements the CBAM and who is impacted by it?

• Implementation: The European Commission designed CBAM, and each Member State’s customs authority enforces it. EU importers of covered goods must register in a CBAM system and report annually.
• Affected parties: EU-based companies importing the goods bear the compliance cost. They must obtain emissions data from their foreign suppliers to fulfill reporting.
• Exporters at risk: Countries with heavy exports of covered goods to the EU will pay more. For instance, India, China and Russia – which export large volumes of steel and other covered goods – will see those exports taxed. Analysts estimate Indian steel exporters could incur about €174 per tonne extra (~₹15,400, ≈16% of value) under full CBAM at current EU carbon prices.
• EU industries benefit: EU producers of the same goods pay no extra cost (carbon costs are already in their production). This gives a relative advantage to European manufacturers.
• Other governments: The UK and Canada are reportedly considering similar border carbon measures, indicating CBAM-like policies may spread beyond the EU.

How does the EU CBAM mechanism operate in practice?

• Emissions reporting: Importers must quantify the CO₂ embedded in each shipment of covered goods. This includes direct emissions from production; some sectors also require reporting indirect emissions (e.g. electricity used).
• Carbon certificates: From 2026, importers surrender CBAM certificates each year. Each certificate corresponds to one tonne of CO₂ and costs the current EU ETS allowance price. The number of certificates equals the reported emissions of the import. For example, if 1 tonne of imported steel contains 2 tCO₂ and the carbon price is €80/t, the importer must purchase €160 worth of certificates per tonne of steel.
• Offset deduction: If a foreign producer shows it has already paid a carbon price abroad (for example, via a domestic carbon tax), the importer is credited that amount. This avoids double taxation of the same emissions.
• Enforcement and penalties: Customs authorities verify the reports and certificate purchases. Failure to report or buy enough certificates can lead to fines or blocked imports. The system thereby enforces compliance.

What is the significance of the EU’s CBAM in climate policy and trade?

• Climate impact: CBAM extends carbon pricing to international trade, potentially reducing global emissions by disincentivizing high-emission production. It helps ensure that EU climate targets account for emissions in imports as well as domestic output.
• Economic fairness: By internalizing the externality of carbon emissions on imports, CBAM levels the playing field. Low-carbon exporters gain an advantage, while high-emitting factories see their goods become more expensive in the EU. This can shift investment toward greener production worldwide.
• Market signaling: As the EU is a large market (~15% of world trade), CBAM sends a strong signal that carbon will be priced globally. Companies worldwide may adopt cleaner technology to maintain access to the lucrative EU market.
• Geopolitical dimension: CBAM has become a major topic in international negotiations. Developing countries see it as a test of climate justice; the EU argues it is necessary for climate protection. The outcome will influence future climate collaboration and trade rules.
• Potential revenue: Although CBAM revenues (from certificates) go into member states’ budgets, the EU has discussed using them for climate purposes. How these funds are used could affect global perceptions of CBAM’s fairness.

What limitations and criticisms has CBAM encountered?

• Limited scope: Initially, CBAM applies only to a narrow list of products. Many emissions-intensive goods (e.g. chemicals, plastics, apparel) are excluded, limiting its overall climate impact until expanded.
• Complexity: Accurately measuring CO₂ in imported goods is difficult. Use of default emission values can overcharge some exporters, while detailed verification requires data many firms lack. This complexity raises compliance costs, especially for smaller exporters.
• Equity concerns: Critics argue CBAM ignores the “common but differentiated responsibilities” principle. Developing countries with lower historical emissions view it as a disguised tariff that shifts the burden of climate action onto them without compensating benefits.
• Legal disputes: Some fear CBAM may conflict with WTO rules. Several countries (including India and China) have signaled possible trade complaints, arguing CBAM could violate non-discrimination provisions unless carefully structured.
• Economic burden: Small exporters and poorer countries face a higher relative impact. Studies project significant effects – for example, Africa’s exports to the EU could fall by ~5.7% under CBAM fees. Without support, many enterprises in developing nations may struggle to adapt.
• Delayed effect: Because CBAM’s reporting phase runs to 2025, the real cost signal only starts in 2026. Critics say this gradual rollout reduces immediate pressure on exporters to decarbonize.

What challenges does the CBAM face in global acceptance and implementation?

• International resistance: By mid-2025, the BRICS bloc officially denounced CBAM as unfair. Overcoming such strong opposition is a diplomatic hurdle for the EU. Achieving buy-in or compromise (for example via WTO or UN climate forums) is not guaranteed.
• Administrative burden: EU customs had to add new procedures, and suppliers worldwide must learn emissions accounting. Ensuring accurate reporting (and preventing fraud or misreporting) across global supply chains is difficult.
• Supply chain shifts: A real concern is that multinational companies may relocate production to the EU (where carbon costs were already paid) to avoid CBAM, instead of paying the border tax. This could hollow out industries in exporting countries and undermine local economies.
• Coordination with carbon markets: If other countries implement their own carbon pricing, aligning them with CBAM is complex. Misalignment could lead to double costs or loopholes, requiring complex bilateral or multilateral arrangements.
• Political balance: The EU must balance climate goals with trade relations. If CBAM is seen as too punitive, it could force the EU to grant exemptions or modify rules, diluting its effectiveness. Maintaining trade partners’ cooperation will require delicate negotiation.
• Time pressure: Industries worldwide have limited time to adapt. Without rapid investment in cleaner technology, sectors like steel and cement in India and elsewhere risk heavy charges or lost markets by 2030–2035.

What could be the way forward to address CBAM concerns and improve cooperation?

• Multilateral dialogue: Climate and trade forums (UNFCCC, WTO, G20) could set guidelines on carbon-adjustment measures. Agreements on standardized emissions accounting or shared rules could build trust and prevent conflicts.
• Technical assistance: The EU has offered guidance and training on CBAM; this support should be expanded. Funding and technology transfer to help exporters measure emissions and upgrade to cleaner processes would ease the burden on developing economies.
• Revenue use: One proposal is to allocate a share of CBAM revenues to climate projects in affected countries. For example, funding renewable-energy initiatives or carbon-offset programs abroad could demonstrate solidarity and ease equity concerns.
• Gradual implementation: Giving least-developed countries extra time or lower rates before full CBAM kicks in could help them prepare. Linking rate increases to verifiable emissions reductions would reward early action.
• Domestic action by exporters: Countries like India are promoting green hydrogen and electric furnaces in steel production. Accelerating these shifts (via subsidies or regulations) will reduce CBAM costs and improve competitiveness.
• Policy refinement: The EU plans to review CBAM’s effects by 2025. Based on feedback, it can adjust emission factors, expand or narrow sectors, and ensure transparency. Iterative improvements will help make CBAM effective and more acceptable globally.

How does the EU CBAM compare with other climate-related trade measures?

• Unlike a typical domestic carbon tax or emissions trading scheme (which only applies to in-country emitters), CBAM is a border-adjustment: it explicitly targets imports based on their carbon content.
• In contrast to import bans on unsustainable goods (e.g. a ban on illegally deforested timber), CBAM uses a price mechanism. It penalizes high-emission goods with a tax rather than prohibiting them outright, which allows continued trade of compliant products.
• Both CBAM and domestic carbon pricing aim to reduce emissions. CBAM’s novelty is its trade focus: its effect depends on export countries’ responses, whereas a domestic carbon tax works within a single economy.
• The table below summarizes key differences between CBAM and traditional domestic carbon pricing:

Conclusion

The EU’s CBAM is a pioneering policy at the intersection of trade and climate. It internalizes the carbon cost of international trade, helping to protect EU climate goals from being undercut by dirty imports. For India and other developing nations, CBAM poses a challenge but also an incentive to decarbonize industry. Balancing ambitious climate targets with equitable trade will require ongoing international cooperation, technology partnerships and support for economies bearing larger transition costs. The success of CBAM will ultimately hinge on collaborative solutions that advance emissions reduction without unduly punishing vulnerable exporters.
