CarbonIQbykyra is a free calculation and simulation engine for CII Rating, EU ETS carbon cost and FuelEU Maritime compliance — built for owners, charterers, technical managers and financiers who need the numbers now, not at the next audit. Run scenarios, project ratings across a full year of Sea Days and Port Days, and score vessel climate alignment under the Poseidon Principles.
A–E
CII rating bands, projected per vessel
100%
EU ETS maritime scope by 2026
−2%
FuelEU GHG intensity cut required from 2025
365
Sea/Port day combinations simulated per voyage year
01
Attained vs. required CII, computed to IMO's DCS methodology. Enter fuel consumption, distance and capacity and get this year's rating letter — plus a projection of next year's band as thresholds tighten.
02
Model EUA exposure per voyage or across the fleet under the ETS phase-in, with intra-EU, extra-EU and at-berth legs weighted correctly. Stress-test against carbon price scenarios before you buy allowances.
03
Track GHG intensity against the declining FuelEU targets, model pooling and banking/borrowing across the fleet, and surface the penalty exposure of a compliance deficit before it's booked.
04
The core simulation: a full matrix of every plausible split of sea days and port days across the year, each cell resolving to a projected CII rating. See exactly how many extra port days it takes to fall a band, or how a busier trading pattern protects one.
05
Calculates vessel and fleet climate alignment against the IMO decarbonization trajectory used in Poseidon Principles reporting — the figure ship financiers and lessors need for disclosure, in the format they expect.
06
Calculates idle speed, idle fuel consumption and idle distance from the parameters you provide — isolating idle time's drag on CII, ETS and FuelEU figures from genuine transit performance.
01
Attained vs. required CII to IMO's DCS methodology, with next year's projected band.
02
EUA exposure per voyage or fleet-wide, stress-tested against carbon price scenarios.
03
GHG intensity vs. declining targets, with pooling and banking/borrowing modeled in.
04
Every plausible trading pattern, each cell resolving to a projected CII band.
05
Vessel and fleet climate alignment against the IMO decarbonization trajectory.
06
Idle speed, fuel consumption and distance from your parameters, isolated from transit performance.
Every calculation traces back to a published standard: IMO's 2023 GHG Strategy and CII/DCS guidance, the EU MRV and ETS Regulations, the FuelEU Maritime Regulation, and the Poseidon Principles framework. No black boxes — every scenario shows the formula and thresholds behind the number.
Owners & operators
Project CII rating across the fleet before the annual filing, and test which trading pattern protects the rating.
Charterers
Model EU ETS and FuelEU cost exposure into a charter before you fix it, not after the invoice.
Fleet technical managers
Run the Sea Days / Port Days matrix per vessel to plan drydock and idle time without dropping a band.
Banks & financiers
Generate the Poseidon Principles alignment score needed for portfolio climate disclosure.
