2026 phase-in at 100%
Applies the surrender percentage for the emission year you pick: 40% for 2024 emissions, 70% for 2025, 100% for 2026 onwards. A carrier still billing on 70% is billing last year's rule.
50% or 100% voyage scope
Emissions are 100% in scope between two EEA ports and at berth in an EEA port, but only 50% on a voyage into or out of the EEA from a non-EEA port. Getting this backwards doubles the line.
Methane and N2O from 2026
CH4 and N2O joined the EU ETS on 1 January 2026, as CO2e. The tool counts them for 2026 emissions and leaves them out for 2024 and 2025, so the same LNG dual-fuel voyage gives a different answer per year.
The euro difference on the line
Compares the allowances actually owed against what the carrier billed and names the gap in euro and in percent, which is the sentence you put in the dispute email.
Surrender deadline
Holds the 30 September surrender date for the emission year so a correction invoice is disputed before the allowances are handed over, not after.

Questions people ask

What does the EU ETS Ocean Surcharge Check actually do?

It re-runs the ETS surcharge line on an ocean freight invoice. You type the emission year, the voyage leg, the CO2 and CH4+N2O tonnes allocated to your shipment, the EUA price and the amount billed. It returns the allowances actually owed, the correct euro figure, and the gap between that and the invoice.

Who is this for?

Freight forwarders, import cost controllers and shippers moving containers into or out of the EEA who receive an ETS or EUA surcharge line from the carrier. It is for the person who has to approve that line, not for the shipping company that reports emissions and surrenders the allowances.

Why will a chatbot not answer this correctly?

Because the rule changed on 1 January 2026 in two places at once. The surrender obligation went from 70% of 2025 emissions to 100% of 2026 emissions, and methane and nitrous oxide entered the system as CO2e. A model trained earlier answers with 70% and CO2 only, and it cannot see which voyage leg you shipped on.

What is free and what does the full version add?

Free covers the whole calculation: 7 typed fields, all 5 checks, unlimited invoice lines, in the popup and on the web page, with no key. The full version at $60 adds a different axis, not more answers - it saves each checked line as a .csv row you keep, and sets reminders 30, 14 and 1 days before the surrender deadline.

What would it cost to have a person check these lines?

A US customs consultant bills $34 to $79 an hour and independent trade-compliance firms charge $150 to $400 an hour, and they normally take a whole freight portfolio rather than a single surcharge line. Ocean post-audit firms work on gainshare, keeping a share of whatever they recover for you.
