Which products are affected—and why this matters for India
The initial scope of the mechanism covers sectors that are both high-emission and heavily traded, including steel, aluminium, cement, fertilisers, electricity, and hydrogen. European authorities have indicated that coverage may expand over time. The United Kingdom has also announced plans for a similar system.
For India, the exposure is significant. Roughly 22 per cent of India’s steel and aluminium exports are destined for the European market. In the financial year 2024–25, those exports were valued at about $5.8 billion. Even before the mechanism became fully operational, exports to Europe fell around 24 per cent year-on-year, a decline that industry participants and analysts link to early compliance friction during the reporting phase that began in late 2023.
How the mechanism works in practice
The system does not collect a tax at the border in the traditional sense. Instead, it operates through a sequence that blends regulation with commercial negotiation.
For each shipment entering Europe, the embedded carbon emissions are calculated at the level of the specific production facility that made the goods. That emissions figure is then multiplied by the prevailing European carbon price, which has recently traded in the €70–€80 per tonne of carbon dioxide range.
The formal obligation to comply falls on the European importer, who must report emissions and, in the charging phase, purchase certificates corresponding to the carbon content of the import. Economically, however, the burden does not remain with the importer. Buyers treat the carbon cost as a procurement expense and push it back through price renegotiation.
The result is that Indian exporters do not write a cheque to European authorities, but still receive lower realised prices.
Why 2026 matters even before full payments begin
Although importers are required to formally surrender carbon certificates only from 2027, the pricing effect begins earlier. Markets anticipate known costs. From 1 January 2026, every shipment entering Europe is priced as if the carbon cost already applies.
For exporters, this means margins adjust now, not later. Contracts are rewritten in advance, reflecting future obligations.
What the carbon cost looks like on an invoice
The most intuitive way to understand the impact is to treat carbon as a line item on an export invoice.
Consider coal-based steel produced using the blast furnace route, which remains common in India. Industry estimates place emissions at around 2.4 tonnes of carbon dioxide per tonne of steel for this method. At a European carbon price of €80 per tonne, this implies a carbon cost of approximately €192 per tonne of steel.
On a typical European sale price of €600 per tonne, the implied carbon charge equals about one-third of the headline price. Importers rarely absorb this fully. Market assessments suggest 50–70 per cent of the cost is pushed back onto exporters.
That translates into a price reduction of roughly €95–€133 per tonne, compressing realised prices by 16–22 per cent. This occurs before accounting for audit fees, data systems, or contract renegotiation costs.
The mechanism therefore behaves not as a compliance formality, but as a structural reset of export margins.
Who ultimately bears the cost
Legally, the system is designed so that European importers purchase the required certificates. Economically, the burden is distributed along the value chain.
- Indian exporters absorb the largest share through lower prices.
- European importers act as transmission points, embedding carbon costs into procurement.
- Consumers may see limited pass-through, constrained by demand sensitivity.
- European public finances ultimately receive revenue via certificate purchases linked to the internal carbon market.
For exporters without strong pricing power or alternative markets, the adjustment is particularly severe.
Why plant-level data is now as important as price
A critical feature of the mechanism is that it does not rely on corporate averages or sustainability disclosures. It is facility-specific and audit-driven.
Only emissions directly linked to production processes and electricity use are counted. If exporters fail to provide verified plant-level data, European authorities require importers to apply default emission values, which are deliberately set 30–80 per cent higher than typical actual emissions to discourage non-reporting.
These defaults can nearly double the carbon cost. Importers will not absorb that risk, making accurate measurement and verification essential for competitiveness. From 2026 onwards, emissions must be certified by auditors accredited under internationally recognised standards, and India currently has a limited pool of such verifiers.
How contracts and production choices are changing
As carbon becomes priced, it is being written directly into contracts. European buyers are increasingly insisting on clauses that:
- pass carbon costs through to exporters,
- reopen prices if carbon prices change,
- require warranties on emissions data accuracy, and
- permit third-party audits of production facilities.
Some exporters are already quoting dual prices: a base commodity price and a carbon-adjusted price linked to verified emissions.
Production routes matter more than ever. Coal-based steel faces the highest burden; gas-based and scrap-based production faces significantly lower costs. The mechanism rewards cleaner processes regardless of geography.
Why India is structurally more exposed
The system allows deductions if a country already imposes a comparable carbon price domestically. India does not operate a nationwide carbon tax at European levels, relying instead on regulatory standards and efficiency programmes. As a result, Indian exporters typically receive little or no offset against the European carbon charge.
Combined with Europe’s importance as a destination market, this creates a disproportionate impact.
The “mid-cap trap”
The adjustment does not affect all exporters equally. Large, integrated firms can invest in cleaner technologies, maintain internal carbon-accounting teams, and spread verification costs across volumes. Mid-sized exporters face a triple squeeze: higher relative compliance costs, weaker bargaining power, and greater exposure to punitive default values.
The structural effect is consolidation. Market access increasingly favours capital-rich, data-ready producers, potentially reshaping India’s export base.
Why a uniform carbon price hits developing exporters harder
A central critique of the mechanism is not the idea of pricing carbon, but how it is priced. Europe applies a single, high carbon price to imports regardless of the exporter’s economic context. While a tonne of carbon dioxide is physically identical everywhere, the cost of reducing or absorbing that tonne is not.
European carbon prices have hovered around €70–€80 per tonne, while China’s prices are far lower and India does not operate a comparable nationwide carbon tax. When Europe extends its price through the border mechanism, it effectively imports a rich-economy cost structure into developing-economy production systems.
Decarbonisation requires heavy upfront investment — cleaner furnaces, better scrap processing, reliable clean power, and access to long-term finance. European producers transition within subsidy-supported, low-cost capital ecosystems. Many Indian producers, especially mid-sized firms, face higher borrowing costs and thinner margins, making the same emissions reduction far more expensive per unit of output.
The result is a “carbon affordability gap”: identical emissions can have unequal economic consequences. One producer absorbs the cost as part of a planned transition; another loses export viability. This is why the mechanism, while emissions-neutral on paper, is widely seen as economically regressive across countries, imposing disproportionate pressure on late-industrialising economies.
Climate policy—and industrial strategy
While framed as a climate-fairness tool, the trade effects mirror industrial protection. Steel and aluminium—responsible for roughly 10 per cent of global emissions—are also among the most protected sectors in advanced economies. The United States maintains high import tariffs; Europe is adding a carbon-linked cost layer.
The mechanism operates on two tracks simultaneously: pricing emissions and reinforcing domestic industrial competitiveness. This dual character explains why exporting countries see it not as neutral regulation, but as climate policy with industrial consequences.
What trade negotiations can and cannot change
Ongoing India–Europe trade talks can ease friction—through mutual recognition of verification systems, transitional buffers, or clearer dispute-resolution rules—but they are unlikely to eliminate the core logic of carbon pricing applied to imports.
The strategic response is therefore two-fold: domestic readiness in measurement and cleaner production, and international negotiation to manage transition costs.
Why this matters
The carbon border mechanism is not a temporary hurdle. It represents a fundamental rewiring of trade around verified emissions intensity. For Indian exporters, the competitive question is no longer only whether they can produce cheaply, but whether they can prove—plant by plant—how much carbon they emit, and still protect margins once Europe prices carbon into trade.
Carbon has become a trade currency. The adjustment now underway is determining who can afford to trade.
