EU CBAM · Definitive period 2026–2034 · Iron & steel, cement, aluminium, fertilisers, hydrogen, electricity

Reading the fine print
of the EU carbon border.

CarbonLenz is an AI CBAM evidence scanner for EU importers. It reads messy supplier emissions evidence, extracts the CBAM fields, flags what's missing, and shows whether relying on EU default values is costing the importer money — from 2026 through 2034. Nobody else does this.

02 Why this exists
The EU Carbon Border Adjustment Mechanism starts charging importers in 2026 and ramps to full exposure by 2034. Importers receive messy, often unverified supplier evidence — and without it, they fall onto punitive EU default values. CarbonLenz turns that evidence into money impact and a next action.

03 About

EU importers pay carbon tax from 2026. Their suppliers send messy evidence. CarbonLenz turns that mess into money.

The EU Carbon Border Adjustment Mechanism (CBAM) starts its definitive phase in 2026. Importers of iron & steel, cement, aluminium, fertilisers, hydrogen, and electricity must declare embedded emissions and surrender CBAM certificates. If the supplier's evidence is incomplete or unverified, the importer falls onto punitive EU default values — and pays more.

CarbonLenz uses AI to read supplier evidence, extract the CBAM fields, check what's missing, and calculate the financial gap between the forced default and the achievable-if-verified cost — across the full 2026–2034 phase-in ramp. All calculations use official EU data with source citations.
