CBAM Quarterly Reporting Calculator

The EU Carbon Border Adjustment Mechanism prices the carbon embedded in imported goods. The core is one line — embedded emissions = quantity × (direct + indirect intensity) — but the certificate liability then layers on the 2026–2034 phase-in and a rebate for any carbon price already paid at origin. Pick a CBAM good, get the embedded tCO₂e, the certificates due, and the euro cost, then jump to the full reporting tool.

The climate disclosure & compliance suite

CBAM is one of a family of mandatory climate-reporting regimes. Each calculator below runs the full methodology on GreenCalculus.com — with structured disclosures, schema-aligned exports, and jurisdiction-specific rules.

Why the cost lags the emissions: During the transitional period (Oct 2023 – Dec 2025) importers file a quarterly CBAM report of embedded emissions with no financial liability. From 2026 the definitive regime begins, but obligations phase in as EU ETS free allocation phases out — only 2.5% of embedded emissions need certificates in 2026, rising to 100% by 2034. A carbon price already paid in the country of production is deductible, so certificates = embedded × phase-in × (1 − origin price ÷ ETS price). Default values are illustrative — the live tool uses the Commission's published default-value tables per good and country.
