⚠️ Very high CBAM exposure. Reducing actual emissions and providing verified data could significantly reduce this.
Estimate only. Actual cost depends on verified embedded emissions, EU ETS price at time of certificate purchase, and applicable deductions.
EMBEDDED EMISSIONS · SCOPE 1, 2 & 3

Scope 3 Embedded Emissions Guide

CBAM vs Full Scope 3: CBAM requires calculating "embedded emissions" = Scope 1 (direct) + Scope 2 (electricity) + precursor embedded emissions. Full Scope 3 (GHG Protocol Categories 1–15) goes much further. We help you with both — CBAM first, then full Scope 3 for your buyers and ESG reporting.
