CarbonChain's Costly Calculus: CBAM's Crippling Default Dilemma for Steel

The European Union's Carbon Border Adjustment Mechanism has crossed a decisive threshold, transforming from a bureaucratic reporting exercise into a live, accruing financial liability for steel importers worldwide. Jack Laing, carbon specialist at United Kingdom-based carbon accounting platform CarbonChain, delivered a forensic & alarming assessment at the Irepas 2026 Spring Conference, revealing that the gap between default emission values & verified actual emissions data could translate into costs two to four times higher for importers relying on published averages rather than installation-level verification. The definitive phase of the mechanism began on January 1, 2026, & the compliance clock is now running. Here is a comprehensive examination of what Laing's presentation revealed, & what it means for every participant in the global steel value chain.

Definitive Phase's Dawning: CBAM's Financial Fangs Finally Bared The transition from the Carbon Border Adjustment Mechanism's transitional reporting phase to its definitive financial phase on January 1, 2026, represents one of the most consequential regulatory inflection points in the history of global steel trade, & Jack Laing, carbon specialist at CarbonChain, was unequivocal in characterizing its significance. "The definitive phase of CBAM, which began on January 1, 2026, has transformed the mechanism from a reporting exercise into a financial mechanism for importers," Laing stated, framing the shift in terms that leave no room for complacency among importers who may have treated the transitional phase as a low-stakes compliance rehearsal. Carbon Border Adjustment Mechanism costs are now actively accruing throughout 2026, & importers must account for these costs in their financial planning & supply chain management. The consequences of failing to do so are not merely regulatory but commercial: as Laing noted, failure to account for these costs shifts the financial burden elsewhere in the supply chain, creating unexpected liabilities for parties who may not have anticipated bearing them. The mechanism's architecture mirrors the European Union Emissions Trading System, the bloc's flagship carbon pricing instrument, creating a deliberate alignment between the carbon cost faced by domestic European producers & the carbon cost applied to imported goods. This alignment is the mechanism's fundamental purpose: to ensure a level playing field between European producers who bear the full cost of carbon compliance under the Emissions Trading System & overseas producers who have historically been able to sell into the European market without equivalent carbon cost obligations. The financial obligations that began accruing on January 1, 2026, will crystallize into actual payment requirements from February 1, 2027, when importers must begin purchasing Carbon Border Adjustment Mechanism certificates. The certificate prices are based on the quarterly average European Union Emissions Trading System price, creating a direct financial link between the carbon price in the European market & the cost imposed on imported goods. For steel importers who have not yet established the verification infrastructure required to use actual emissions data rather than default values, the financial exposure materializing in 2027 could be substantial, & the window for remediation is narrowing rapidly.

Default Values' Devastating Differential: the Punitive Price of Unpreparedness The most immediately alarming finding from Jack Laing's CarbonChain presentation is the magnitude of the cost differential between default emission values & verified actual emissions data, a differential that has the potential to render entire trade flows economically unviable if importers fail to secure installation-level verification from their upstream suppliers. Default values, published by the European Union & based on average emissions by product code, production route, & country of origin, are deliberately designed to be punitive. This is not an accidental feature of the mechanism but an intentional design choice: by setting default values above the actual emissions of most producers, the European Union creates a powerful financial incentive for importers to invest in the verification infrastructure required to use actual emissions data rather than relying on published averages. Laing was explicit about the scale of this incentive: the gap between default & actual emissions can reach two to four times higher costs, particularly for products sourced from countries such as China, India, & South Africa. This means that an importer sourcing steel from a Chinese blast furnace, basic oxygen furnace producer & relying on default values rather than verified actual emissions data could face Carbon Border Adjustment Mechanism costs two to four times higher than an importer sourcing from the same producer but armed installation-level verified emissions data. The financial implications of this differential are enormous. Laing provided a concrete illustrative example: a steel re-roller installation an emissions intensity of 1.343 metric tons of CO₂ per metric ton of steel, compared to a benchmark of 0.782 metric tons of CO₂ per metric ton, results in a calculated Carbon Border Adjustment Mechanism cost of approximately €46.42 ($50.10 USD) per metric ton, assuming a European Union Emissions Trading System price of €80 ($86.40 USD) per metric ton. This example demonstrates that even for a producer whose actual emissions are known & verified, the cost exposure above the benchmark is substantial. For a producer relying on default values that may be significantly higher than actual emissions, the cost exposure is correspondingly greater, & the financial incentive to invest in verification is correspondingly more compelling. The benchmarks against which emissions are measured decrease annually in line the phase-out of free European Union Emissions Trading System allowances, meaning that cost exposure begins from the first year & increases over time, creating an escalating financial pressure that will intensify throughout the decade.

Compliance Calendar's Crucial Cadence: Timelines, Thresholds & Tight Deadlines The compliance timeline for the Carbon Border Adjustment Mechanism's definitive phase is precisely defined, & Jack Laing's presentation at the Irepas conference provided a detailed roadmap of the obligations & deadlines that importers & their upstream producers must navigate in the coming months. For the 2026 monitoring year, the compliance sequence unfolds as follows: operators must collect emissions data throughout 2026, a continuous process requiring real-time monitoring & recording of production-level emissions across all relevant installations. In the first quarter of 2027, operators must prepare emissions reports based on the data collected during 2026, a document that will form the basis for the importer's Carbon Border Adjustment Mechanism declaration. By the second quarter of 2027, these emissions reports must be verified by an accredited third-party verifier, introducing an external quality assurance step that adds both time & cost to the compliance process. Importers must begin purchasing Carbon Border Adjustment Mechanism certificates from February 1, 2027, a date that represents the first actual cash outflow associated the mechanism's financial obligations. Certificate prices are based on the quarterly average European Union Emissions Trading System price, creating a direct & transparent link between the European carbon market price & the cost imposed on imported goods. The final deadline for submitting Carbon Border Adjustment Mechanism declarations & surrendering certificates for 2026 emissions is September 30, 2027, a date that will become one of the most significant compliance deadlines in the global steel trade calendar. From 2027 onward, the compliance obligations become more complex: importers must comply a quarterly obligation to hold Carbon Border Adjustment Mechanism certificates covering at least 50% of embedded emissions, a requirement that demands continuous monitoring of import volumes & emissions data rather than a single annual reconciliation. Laing noted that no certificate purchases are required during 2026 due to transitional provisions, but this grace period should not be mistaken for an absence of obligation: the financial liabilities for 2026 emissions will crystallize in 2027, & importers who have not prepared their verification infrastructure during 2026 will face the full burden of default values when those obligations come due.

Value Chain's Vulnerable Vertices: Producers, Importers & Verification's Vital Role One of the most practically significant aspects of Jack Laing's CarbonChain presentation was his analysis of how Carbon Border Adjustment Mechanism compliance responsibilities are distributed across the steel value chain, & the dependencies & potential bottlenecks that this distribution creates. The mechanism assigns distinct responsibilities to different parties: producers are responsible for generating installation-level emissions data, the granular, facility-specific measurements that form the foundation of the entire compliance architecture. Importers, designated as declarants under the mechanism's terminology, are responsible for reporting to the relevant authorities & purchasing the certificates required to cover the embedded emissions in their imports. This division of responsibility creates a critical dependency: importers rely entirely on verified emissions data from their upstream producers to fulfill their own compliance obligations. If a producer cannot or will not provide verified installation-level emissions data, the importer is forced to fall back on default values, incurring the punitive cost differential that Laing identified as potentially two to four times higher than costs based on actual verified data. This dependency makes verification capacity a potential bottleneck in 2027, as the demand for third-party verification services from accredited verifiers is expected to surge as the September 30, 2027, declaration deadline approaches. The verification industry, while growing, may not have sufficient capacity to process the volume of verification requests that will be generated as importers & their suppliers scramble to secure verified emissions data ahead of the deadline. Laing's identification of this bottleneck risk is a practical warning that importers should not wait until 2027 to initiate the verification process: the earlier they engage their suppliers & accredited verifiers, the greater the likelihood of securing verified data in time to avoid the default value penalty. For producers, the implication is equally clear: the ability to provide verified emissions data to importers is rapidly becoming a commercial prerequisite for maintaining access to European markets on competitive terms, & investment in the measurement, reporting, & verification infrastructure required to generate that data is no longer optional but strategically essential.

Country-Level Complexity: Differential Destinies & Divergent Decarbonization Depths The country-level impact of the Carbon Border Adjustment Mechanism varies significantly across the major steel-exporting nations, & Jack Laing's presentation provided a nuanced assessment of the specific challenges & opportunities facing producers in different jurisdictions. Turkey, as the largest exporter of long steel products to the European Union, occupies a relatively favorable position due to its electric arc furnace-dominant production route, which generates substantially lower CO₂ emissions per metric ton of steel than blast furnace, basic oxygen furnace production. However, uncertainties remain regarding the treatment of carbon pricing deductions for Turkish producers, & the resolution of these uncertainties will materially affect the net Carbon Border Adjustment Mechanism cost exposure of Turkish exporters. India faces a particularly complex compliance landscape due to its mixed production routes, encompassing both blast furnace, basic oxygen furnace & electric arc furnace production, & the complexity of its precursor supply chains, which involve multiple production steps each generating embedded emissions that must be tracked & verified. Egypt & Commonwealth of Independent States countries are exposed to the full Carbon Border Adjustment Mechanism costs due to the absence of recognized carbon pricing systems in their jurisdictions: the mechanism allows deductions for carbon prices paid in the country of production, but only for pricing systems that the European Union recognizes as equivalent or comparable to its own Emissions Trading System. China, the world's largest steel producer, presents the highest embedded emissions profile among major exporters, reflecting its overwhelming reliance on blast furnace, basic oxygen furnace production using high-coal-intensity inputs. Chinese producers face some of the highest Carbon Border Adjustment Mechanism cost exposures globally, a factor that will increasingly affect the competitiveness of Chinese steel exports in the European market as the mechanism's financial obligations escalate. Vietnam faces growing exposure through its expanding electric arc furnace-based production using imported scrap, a production route whose emissions profile depends heavily on the carbon intensity of the electricity grid powering the furnaces.

Scope's Sweeping Expansion: Indirect Emissions, Downstream Goods & 2028's Disruption The Carbon Border Adjustment Mechanism as it currently stands covers direct emissions from a defined set of industrial sectors, but Jack Laing's presentation made clear that the mechanism's scope is set to expand significantly in the coming years, creating additional compliance complexity & cost exposure for a much wider range of importers & supply chain participants. The mechanism is expected to expand to include indirect emissions, designated as Scope 2 emissions, which encompass the CO₂ generated in producing the electricity consumed by manufacturing processes. For electricity-intensive steel production routes, particularly electric arc furnace operations in countries electricity grids are heavily dependent on fossil fuels, the inclusion of Scope 2 emissions will substantially increase cost exposure, potentially transforming the relative competitive position of producers in different jurisdictions. The product scope of the mechanism is projected to widen to include downstream goods such as screws, tubes, & wire products, categories that currently fall outside the mechanism's coverage but that contain significant embedded steel emissions. This expansion is expected to cover approximately 180 additional product categories & to bring an estimated 7,500 additional importers into the compliance framework by 2028, a dramatic broadening of the mechanism's reach that will require a corresponding expansion of verification capacity, compliance infrastructure, & regulatory expertise across the supply chain. For steel producers whose products are currently outside the mechanism's scope, this expansion represents a significant future compliance obligation that should be factored into investment & operational planning decisions being made today. The combination of Scope 2 inclusion & downstream product expansion means that the Carbon Border Adjustment Mechanism of 2028 will be a substantially more complex & financially demanding instrument than the mechanism that entered its definitive phase in January 2026, & the organizations that invest in compliance infrastructure now will be far better positioned to manage that expanded obligation than those who defer preparation until the expanded scope comes into force.

United Kingdom's Unilateral CBAM: Dual Compliance's Daunting Double Burden A development that received particular attention in Jack Laing's CarbonChain presentation is the imminent introduction of the United Kingdom's own Carbon Border Adjustment Mechanism, which is set to enter into force on January 1, 2027, creating a separate but parallel regulatory framework that will require dual compliance from exporters targeting both European Union & United Kingdom markets. The United Kingdom Carbon Border Adjustment Mechanism covers the same core industrial sectors as its European Union counterpart, including iron & steel, aluminum, cement, fertilizers, & hydrogen, but it operates as an entirely independent regulatory instrument the United Kingdom's own Emissions Trading Scheme rather than the European Union Emissions Trading System. Key features of the United Kingdom mechanism include a £50,000 ($63,500 USD) annual threshold below which importers are exempt from compliance obligations, & quarterly Carbon Border Adjustment Mechanism rates linked to the United Kingdom Emissions Trading Scheme price rather than the European Union price. The existence of two separate but structurally similar Carbon Border Adjustment Mechanisms, operating on different legal bases, different pricing mechanisms, & different administrative frameworks, creates a significant additional compliance burden for exporters who sell into both markets. These exporters must maintain separate emissions reporting & verification processes for each mechanism, purchase certificates under two different systems, & navigate two sets of regulatory requirements that, while similar in concept, differ in detail in ways that matter enormously for compliance purposes. For steel producers in countries such as Turkey, India, & South Korea, which export significant volumes to both the European Union & the United Kingdom, the dual compliance requirement represents a material increase in administrative complexity & cost. Laing's conclusion was measured but unambiguous: Carbon Border Adjustment Mechanism cost exposure is already material & increasing, the difference between default & verified emissions data translates into millions of euros in potential cost impact, & the combination of scope expansion, verification requirements, & dual compliance obligations will increase compliance complexity across the steel value chain in ways that demand immediate & sustained attention from every participant in global steel trade.
