Calculate your vessel's Carbon Intensity Indicator (CII) rating in seconds. Get your A–E rating, full-year projection, and improvement recommendations.
Methodology: AER = CO₂ ÷ (GT × Distance), where CO₂ = Fuel × Conversion Factor (per IMO MEPC.245(66)). Reference CII and rating boundaries per IMO MEPC.339(77) and MEPC.354(78). Required CII applies the annual reduction factor vs 2019 baseline. This tool is for indicative purposes — official reporting requires verified IMO DCS data from your flag state or RO.
