COMPLIANCE & REGULATORY
The Carbon Border Adjustment Mechanism requires exporters of goods in covered sectors to declare the embedded carbon content of every tonne sold into EU markets. From 2026, that declaration becomes a carbon cost — calculated quarterly, submitted to the EU CBAM registry, and directly tied to the carbon price EU producers pay under the Emissions Trading System.
For manufacturers and producers in Iron & Steel, Cement, Aluminium, Fertilizers, Electricity, and Hydrogen, CBAM is not a future obligation. It is an active reporting requirement with quarterly deadlines and real financial consequences if the calculation is wrong.
Iron & Steel, Cement, Aluminium, Fertilizers, Electricity, and Hydrogen — including downstream products and processors within each category. Any company exporting these goods to the EU is in scope, regardless of company size or export volume.
CBAM declarations are submitted every three months. From 2026, each declaration carries a direct carbon cost — the difference between the carbon price paid at production and the EU ETS carbon price. Errors in calculation are not corrected retroactively without penalty exposure.
Embedded carbon calculations require production-process data at site and product level, sector-specific emission factors, and methodology alignment with EU CBAM regulation. Default values are available — but relying on them without assessing sector-specific alternatives can lead to significantly overstated carbon costs.
CBAM embedded carbon calculations are not a sustainability exercise. They are a financial calculation — one that determines how much your business pays per tonne of goods exported to the EU from 2026. Companies that invest in accurate, production-level calculations consistently pay less than those relying on default values or conservative estimates.
Semtrio's CBAM advisory is built around precision. We work directly with process teams, sustainability departments, and procurement to map every relevant emission source across your production sites, apply the correct methodology for your specific goods and sector, and produce calculation files that hold up to EU declarant verification.
Our delivery covers the full CBAM obligation cycle: embedded carbon calculation, quarterly submission package preparation, validation support, and the regulatory update monitoring that keeps your methodology current as CBAM requirements evolve. We have delivered 300+ embedded carbon calculations and 150+ submission packages across Iron & Steel, Cement, Aluminium, Fertilizers, Electricity, and Hydrogen operations — with 100% of submission deadlines met.
OUR PROCESS
A complete CBAM compliance system — from first calculation to quarterly submission.
From quarterly reporting to permanent CBAM infrastructure.
For organizations managing CBAM across multiple facilities, product lines, or export markets, a quarterly calculation project is not a sustainable operating model. The definitive CBAM regime requires continuous data, year-on-year comparability, and the ability to answer — in real time, as production runs — what the carbon cost of each product will be when it reaches the EU border.
Carbondeck CBAM is the digital infrastructure that makes this possible. The platform creates a digital twin of your production lines — modeling facilities, production routes, and material inputs in a single system, integrated with your ERP to receive production and energy data continuously. Product emission intensity is tracked by facility and production line in real time, with financial impact calculated against live EU ETS carbon prices. The result is a CBAM data position that is always current, always audit-ready, and directly tied to the pricing decisions that protect your EU margin.
As an accredited Climateware consulting partner, Semtrio deploys Carbondeck CBAM for clients who need a permanent system — not a quarterly rebuild. We configure the platform, run the initial scope and data mapping, and train your team to own the ongoing process. Semtrio provides the advisory expertise. Carbondeck provides the infrastructure.
Explore Carbondeck CBAMCBAM embedded carbon calculations draw on the same emissions data as your corporate GHG inventory — structuring both together eliminates duplication and improves accuracy across all frameworks.
Learn moreFor manufacturers in CBAM-covered sectors, the same production-level emissions data that supports CBAM calculations is the foundation of CDP Climate disclosure — structuring both from a single data source eliminates duplication and strengthens performance across frameworks.
Learn moreEU buyers requiring CBAM-compliant suppliers frequently also require EcoVadis scores — managing both as a coordinated system reduces data duplication and strengthens supplier positioning.

CBAM embedded carbon calculation is not a generalist sustainability exercise. It requires production-process knowledge, sector-specific methodology, and direct familiarity with how the EU declarant system works in practice — including how it changes as the regulation matures from transitional phase into the definitive regime.
Semtrio has delivered over 300 embedded carbon calculations and more than 150 CBAM submission packages across operations in Iron & Steel, Cement, Aluminium, Fertilizers, Electricity, and Hydrogen. Every submission has been delivered ahead of its quarterly deadline. That record reflects both the rigour of our methodology and the discipline of our delivery process — not just in any single engagement, but consistently across a portfolio of exporters with different production profiles, data quality levels, and site structures.
Our CBAM delivery integrates with Carbondeck where clients need a permanent data infrastructure for multi-site, multi-product calculation management. For clients with complex production footprints — multiple sites, downstream processed products, or multi-entity export structures — Carbondeck provides the data architecture that makes quarterly CBAM reporting a system rather than a project.
