CBAM Glossary
Every CBAM term you need to know, explained simply for Indian exporters. From embedded emissions to CN codes, default values to Authorised Declarants — your complete reference guide.
CBAM Fundamentals
CBAM(Carbon Border Adjustment Mechanism)
A regulation by the European Union that imposes a carbon price on certain goods imported into the EU. It mirrors the EU Emissions Trading System (EU ETS) price for domestic producers, ensuring imported goods face the same carbon cost. CBAM applies to iron & steel, aluminium, cement, fertilizers, electricity, and hydrogen.
EU ETS(EU Emissions Trading System)
The EU's carbon market where European manufacturers buy and surrender emission allowances. CBAM is designed to extend the EU ETS carbon price to imports, so that foreign producers face the same carbon cost as EU producers. The CBAM certificate price tracks the EU ETS allowance price.
CBAM Transitional Period
The phase from October 2023 to December 2025 where EU importers must report embedded emissions quarterly but do not yet need to purchase CBAM certificates. The definitive period begins January 2026, when financial obligations kick in.
Definitive Period
Starting January 2026, the phase where CBAM becomes fully operational. EU importers must purchase and surrender CBAM certificates based on the actual embedded emissions of imported goods. Default values are heavily penalized, making actual emission data from exporters essential.
Carbon Price
The price per tonne of CO₂ equivalent that must be paid under CBAM. This tracks the EU ETS price, which has fluctuated between €50-100/tCO₂. For Indian exporters, this translates to a significant additional cost on EU-bound shipments if default values are used instead of actual emission data.
Carbon Leakage
The risk that companies relocate carbon-intensive production to countries with less stringent climate policies, thereby increasing global emissions. CBAM was designed to prevent carbon leakage by ensuring imports face the same carbon price as EU-produced goods.
Carbon Tax Credit
If an exporter has already paid a carbon price in their home country (e.g., a carbon tax or ETS), this amount can be deducted from the CBAM certificate obligation. India does not currently have a carbon pricing mechanism equivalent to the EU ETS, so Indian exporters generally cannot claim this deduction.
Emissions & Calculations
Embedded Emissions
The total greenhouse gas emissions (measured in tonnes of CO₂ equivalent) released during the production of CBAM goods. This includes both direct emissions (Scope 1) from the manufacturing process and, for some goods like aluminium, indirect emissions (Scope 2) from electricity consumption. Accurate embedded emission data is critical — it directly determines your CBAM tax liability.
Direct Emissions (Scope 1)
Greenhouse gas emissions that occur directly from the production process — such as emissions from blast furnaces in steelmaking, chemical reactions in cement kilns, or combustion of fuels on-site. These are always included in CBAM embedded emission calculations for all covered sectors.
Indirect Emissions (Scope 2)
Emissions from the generation of electricity consumed during production. Under CBAM, indirect emissions are currently mandatory for aluminium and relevant for other sectors. For Indian aluminium producers, this is especially significant because India's coal-heavy power grid has high emission factors.
Default Values
Emission values assigned by the EU when an exporter fails to provide actual production data. Default values are set at the worst-performing installations in the EU (or based on country averages plus a markup), resulting in significantly higher CBAM costs — often 30-50% more than actual values for efficient Indian producers. Using actual data from CarbonSettle can save up to 40%.
Specific Embedded Emissions
Embedded emissions per unit of product, expressed in tonnes of CO₂e per tonne of goods (tCO₂e/t). This is the key metric used to calculate CBAM liability. Lower specific embedded emissions mean lower CBAM costs for your EU buyer.
Grid Emission Factor
The amount of CO₂ emitted per unit of electricity generated in a specific grid or region, expressed in tCO₂/MWh. India's national grid emission factor is approximately 0.7-0.8 tCO₂/MWh due to high coal dependence. CarbonSettle uses CEA-verified India-specific grid factors for accurate calculations rather than generic international defaults.
Precursor Products
Intermediate goods used in the production of CBAM goods. For example, pig iron is a precursor to steel. Under CBAM, emissions from precursor production must be included in the embedded emissions of the final product. This means emissions from your entire supply chain matter.
Emission Intensity
The amount of greenhouse gas emitted per unit of output, typically expressed as tCO₂e per tonne of product. Lower emission intensity means lower CBAM costs. Indian exporters who can demonstrate lower emission intensity through actual data (rather than defaults) can significantly reduce their EU buyer's CBAM bill.
Compliance & Reporting
CBAM Certificate
A digital certificate purchased by the EU importer (Authorised Declarant) to cover the embedded emissions of imported CBAM goods. Each certificate covers one tonne of CO₂e. The price is linked to the weekly average EU ETS allowance auction price. Certificates must be surrendered annually by May 31st.
Authorised Declarant
The EU-based importer or customs representative who is registered with the CBAM Authority and is legally responsible for reporting embedded emissions and purchasing CBAM certificates. Indian exporters don't directly buy CBAM certificates — their EU buyer's Authorised Declarant does. However, the exporter must provide the actual emission data.
CN Code(Combined Nomenclature Code)
The EU's product classification system used to identify which goods fall under CBAM. Each exported product is mapped to a CN code (e.g., CN 7206 for iron, CN 7601 for unwrought aluminium). The CN code determines which CBAM reporting rules and emission calculation methodologies apply.
CBAM Report
The formal declaration submitted by the Authorised Declarant to the EU CBAM Authority. It contains the quantity of imported goods, their embedded emissions, and any carbon price already paid in the country of origin. From 2026, reports must be submitted annually and are the basis for CBAM certificate obligations.
EU XML Format
The specific XML data format required by the EU CBAM registry for submitting emission reports electronically. Exporters need to provide data in this exact format for their EU importers. CarbonSettle automatically generates EU-compliant XML files from your production data.
Installation
In CBAM context, the physical production facility (factory, plant, or mill) where CBAM goods are manufactured. Each installation must track and report its emissions separately. One company may operate multiple installations, each with different emission profiles.
Verification
The process of independently auditing and confirming the accuracy of reported embedded emissions. From 2026, CBAM emission data must be verified by an accredited verifier. CarbonSettle provides full audit preparation and verifier coordination as part of its managed service.
CBAM Authority
The national authority in each EU member state responsible for implementing CBAM — registering Authorised Declarants, selling CBAM certificates, and overseeing compliance. Each member state has its own CBAM Authority.
Quarterly CBAM Report
During the transitional period (Oct 2023 – Dec 2025), EU importers were required to submit quarterly reports detailing the embedded emissions of imported CBAM goods. From 2026, reporting shifts to annual declarations with financial obligations.
Industry-Specific Terms
BF-BOF(Blast Furnace - Basic Oxygen Furnace)
The traditional steelmaking route using iron ore, coal/coke in a blast furnace to produce pig iron, then converting it to steel in a basic oxygen furnace. BF-BOF is the most carbon-intensive steelmaking method, with specific emissions of 2.0-2.5 tCO₂/t steel. Most large Indian steel plants (SAIL, Tata Steel, JSW) use this process.
EAF(Electric Arc Furnace)
A steelmaking process that melts scrap steel or DRI using electric arcs. EAF has lower direct emissions than BF-BOF but its carbon footprint depends heavily on the electricity source. In India, where the grid is coal-heavy, EAF Scope 2 emissions can be significant.
DRI(Direct Reduced Iron)
Iron produced by reducing iron ore using natural gas or coal, without melting. DRI (also called sponge iron) is used as feedstock for EAF steelmaking. India is the world's largest DRI producer. DRI-EAF is a common route for Indian secondary steelmakers.
CEA(Central Electricity Authority)
India's government body that publishes official grid emission factors for the Indian power grid. CEA data is critical for CBAM calculations because it determines the Scope 2 (indirect) emission component. CarbonSettle uses the latest CEA-verified data for accurate calculations.
Clinker
The intermediate product in cement manufacturing, produced by heating limestone and other materials in a kiln at ~1450°C. Clinker production is extremely carbon-intensive due to both fuel combustion and the chemical release of CO₂ from limestone (calcination). Clinker and cement are both covered under CBAM.
Calcination
The chemical process in cement production where limestone (CaCO₃) is heated to release CO₂ and produce calcium oxide (CaO). This process emission accounts for approximately 60% of cement's carbon footprint and cannot be reduced through energy efficiency alone.
