Maritime carbon compliance and green ship finance. SeaO2 takes one voyage — fuel, route, vessel particulars — and returns what EU ETS will cost, what FuelEU will penalise, which abatement investment pays back fastest, and where your fleet sits against Poseidon Principles.
EU ETS phase-in from 2026. Every tonne of CO₂ on an EEA voyage now carries a price.
The annual deadline to surrender allowances for the previous year's emissions.
FuelEU greenhouse gas intensity target by 2030, tightening from −2% today.
These are regulatory facts the platform calculates against — not product performance claims.
Fuel type and consumption, route scope, vessel particulars. The simulator returns Well-to-Wake emissions, EU ETS allowance cost at the applicable phase-in rate, FuelEU compliance balance and penalty, and CII rating.
FuelEU surpluses on cleaner vessels are matched against deficits elsewhere, including the RWD=2 incentive multiplier for renewable fuels. Time-charter ETS liability is split between owner and charterer along BIMCO lines.
MACC ranks abatement measures by cost per tonne of CO₂ and payback period. Fleet AER is plotted against Poseidon Principles trajectories, and the result exports as a PDF report for the bank.
Shipowners and technical managers pricing 2026 exposure before it lands. Charterers splitting ETS liability under BIMCO clauses. Maritime lenders checking a borrower's Poseidon alignment before the margin is set.
