Dewan ETS Calculator
Free EU & UK ETS carbon calculator for shipping voyages
Instant EU & UK ETS carbon liability estimates for shipping voyages — dry bulk, tankers, containers, gas carriers and Ro-Ro. Free, no sign-up.
Hey PH 👋
I built Dewan because shipping professionals were calculating
EU ETS costs in spreadsheets with wrong formulas — or paying
consultants for a number that takes 30 seconds to compute correctly.
The rules are genuinely tricky: a Hamburg→Felixstowe voyage
triggers both EU ETS (50% sea leg) and UK ETS (100% port stay)
independently, in different currencies. Most tools get this wrong.
Dewan is free, no sign-up, and the methodology is fully documented
at dewan.ai/methodology.
Would love feedback from anyone in maritime, carbon markets, or
shipping finance — happy to answer questions about the calculation
logic.
