Carbora estimates your Carbon Border Adjustment Mechanism liability line by line: embedded emissions, the official phase-in factor for your reference year, rebate for carbon already priced abroad, certificates to surrender — and a professional PDF declaration report. No account, no subscription.
| Good | Qty | tCO2e | Cost |

Free tools multiply emissions by the full carbon price and overstate your 2026 cost ~40×. Carbora applies the official phase-in factor (2.5% in 2026, rising to 100% in 2034) for the year you choose.
If your supplier's country already prices carbon, Article 9 lets you deduct it. Carbora nets it off per line — most calculators ignore it.
Add every CN line of a mixed shipment — steel, aluminium, cement — each with its own default value, quantity and origin. Get a professional PDF report for your CBAM declarant.

Carbora is an automated estimation tool. Figures use indicative EU default emission values and the certificate price you enter; your actual liability depends on verified producer data, the official default values in force, and the quarterly EUA price. This is not legal, customs or tax advice. Confirm with your authorised CBAM declarant or competent authority.
