Calculators
Maritime compliance calculators
Each one runs the same function the platform runs, on coefficients cited to the instrument and recomputed at every build. No sign-up, no data kept.
IMO CII
IMO CII rating calculator
Attained CII, required CII and the A–E band for one ship-year, computed with the same engine and the same MEPC coefficients this site publishes.
EU ETS
EU ETS shipping cost calculator
Allowances to surrender for one ship-year under the maritime EU ETS, computed with the same engine and the same Directive shares this site publishes, plus the cost at whatever EUA price you enter.
FuelEU
FuelEU Maritime penalty calculator
Well-to-wake GHG intensity, the compliance balance against the year's target and the penalty for one ship-year — computed with the same engine and the same Annex II factors this site publishes.
FuelEU
FuelEU Maritime pooling calculator
Whether an Article 21 pool is valid, how the surplus is allocated across the ships and how much penalty the pool avoids — computed with the same engine the platform runs.
More calculators are being added as each regulation's compute path is verified. A calculator only ships once its numbers are recomputed against the engine at build time — an unverified figure is worse than no tool.
