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.
