Carbon Footprint Assessment Becomes Critical for Indian Manufacturers as EU CBAM Rules Take Effect in 2026

India's iron and steel exports to the European Union dropped 24.4% between FY24 and FY25, falling from USD 7.71 billion to USD 5.82 billion, with iron and steel shipments alone down 35.1% to USD 3.05 billion. This is not a demand slowdown. It is the earliest visible cost of not measuring carbon.

The European Union's Carbon Border Adjustment Mechanism entered its definitive phase on 1 January 2026, and the EU, which accounted for €118 billion in goods trade with India in 2025 and 11.1% of India's total trade, is now attaching a verified carbon cost to every tonne of steel, aluminium, cement, and fertiliser crossing its border. For Indian manufacturers, carbon footprint assessment has moved from a sustainability talking point to a line item that determines whether an export order is even worth taking.

Why 2026 Is the Inflection Point:

Three regulatory shifts have converged in the same 12-month window, and together they explain why carbon footprint assessment has become urgent rather than optional for Indian manufacturers.

● CBAM's definitive phase: After a reporting-only transitional period running from October 2023 to December 2025, EU importers must now purchase CBAM certificates to cover the verified embedded emissions in every shipment, with the first annual declaration and certificate surrender for 2026 imports due by 30 September 2027. Without verified plant-level emissions data, exporters are assigned EU default values that assume the dirtiest production route in their category, and these defaults carry a markup that rises 10% in 2026, 20% in 2027, and 30% from 2028 onward.
● SEBI's BRSR Core mandate: India's Business Responsibility and Sustainability Reporting framework already requires the top 1,000 listed companies by market capitalisation to disclose environmental, social, and governance data, and reasonable assurance on BRSR Core indicators became mandatory starting FY 2024-25, pulling carbon and resource data further up the audit chain.
● India's Carbon Credit Trading Scheme: The CCTS is being positioned as the domestic mechanism to internalise carbon costs at home in the same sectors CBAM targets, giving manufacturers a reason to establish credible baseline emissions data now rather than waiting for a border levy to force the issue.

The Cost of Not Measuring: Sector-Specific CBAM Exposure:

Carbon cost exposure varies sharply depending on production route, which is exactly why manufacturers who cannot document their real emissions face the steepest penalties. Reported figures from early 2026 illustrate the gap:

● Indian blast-furnace-based hot-rolled steel faces a CBAM cost of roughly €254 per tonne under EU default values, compared with about €100 per tonne for Turkish electric-arc-furnace steel and around €94 per tonne for Vietnamese steel, since the same product carries very different carbon costs depending on the production route
● Indian aluminium carries a default CBAM cost of around €50 per tonne, though separate industry estimates suggest coal-dependent aluminium exports could face additional costs of USD 1,500 to USD 1,600 per tonne once broader cost pass-through is accounted for
● Cement producers face a structurally harder problem, since process emissions from limestone calcination cannot be eliminated by switching fuels alone, making carbon capture the primary long-term compliance route
● Estimates for the cement and steel sectors put profit margin declines in a range of USD 65 to USD 160 per tonne between 2026 and 2036 as CBAM costs compound
The gap between a verified emissions figure and a default value is the single biggest lever a manufacturer controls, and it is only available to those who have already completed a structured carbon footprint assessment.

What a Carbon Footprint Assessment Actually Measures:

A carbon footprint assessment for Indian manufacturing operations follows the GHG Protocol Corporate Standard, which organises emissions into three scopes:

● Scope 1: Direct emissions from fuel combustion, process reactions, and fugitive sources at the facility itself
● Scope 2: Indirect emissions from purchased electricity, calculated using state-wise emission factors published by the Central Electricity Authority
● Scope 3: Emissions across the value chain, including raw material extraction, logistics, product use, and disposal, which for many manufacturers make up the largest share of total footprint

Emission factors for this exercise are drawn from India-specific sources, CEA data for grid electricity and IPCC methodologies for combustion emissions, rather than generic global averages, since regional grid mix and fuel composition materially change the result. The output is structured to feed multiple downstream requirements at once: CDP disclosure, Science Based Targets initiative pathway alignment, BRSR compliance, and CBAM-grade documentation for EU-facing exporters.

Building Assessment Capability Ahead of Compliance Deadlines:

Manufacturers that treat carbon footprint assessment as a one-time reporting exercise typically fall behind the compliance curve. A more durable approach includes:

● Establishing installation-level data collection systems rather than annual spreadsheet-based estimates, since third-party verification under CBAM's definitive phase requires auditable, plant-level records
● Engaging EU-recognised or ISO 14065-compliant verifiers early, given that verification capacity is limited and demand is rising sharply across steel, aluminium, and cement exporters simultaneously
● Mapping Scope 3 emissions across the supply chain, since customer-driven ESG due diligence from European and North American buyers increasingly extends scrutiny beyond the manufacturer's own gate
● Aligning internal carbon data systems with both BRSR Core assurance requirements and CBAM verification standards, so the same underlying dataset serves domestic and export compliance without duplicated effort

The Indian government has also signalled support for smaller exporters navigating this transition, with a proposed scheme to cover a significant share of CBAM compliance costs for micro, small, and medium enterprises, recognising that verification and data infrastructure costs fall disproportionately hard on smaller manufacturers without in-house sustainability teams.

Beyond Compliance: The Business Case for Carbon Data:

Carbon footprint assessment is increasingly a competitiveness tool, not just a compliance obligation. Manufacturers with verified low-carbon production routes can access premium demand segments and defend unit pricing even as certificate costs rise, since carbon differentiation with auditable data is becoming a genuine market differentiator rather than a marketing claim. Conversely, manufacturers exporting largely to the EU without diversification face compounding costs as CBAM's default-value markup climbs annually, while those diversifying toward markets in Africa, West Asia, and Latin America, paired with credible low-carbon data, can defend margins that pure EU-dependent exporters cannot.

Domestically, India already contributes nearly 7% of global greenhouse gas emissions, and industrial water demand is projected to exceed supply by over 50% by 2030, underscoring that carbon and resource data are converging into a single sustainability data infrastructure that manufacturers need regardless of export exposure.

IMARC Engineering's Approach to Carbon Footprint Assessment:

IMARC Engineering conducts Scope 1, Scope 2, and Scope 3 carbon footprint measurement for manufacturing operations across pharmaceuticals, chemicals, food processing, FMCG, and industrial sectors in India, using India-specific emission factors and structuring outputs to meet CDP, SBTi, and BRSR requirements alongside export market ESG due diligence. The approach extends into decarbonisation pathway development for manufacturers pursuing SBTi targets or net zero commitments, translating a verified emissions baseline into a specific, sequenced set of reduction measures.

Conclusion:

Carbon footprint assessment in India has moved from an ESG talking point to a financial necessity, driven by CBAM's definitive phase, BRSR Core assurance, and rising customer-driven due diligence. Manufacturers that build verified, plant-level emissions data now protect export margins and unlock premium markets. Those that wait face rising default-value penalties with every passing compliance year.
