Carbon Intensity Calculations for Shipping
Measure your fleet's carbon intensity (CII)
Our CII Assessment tool
calculates the carbon intensity indicator for your ship from just nine datapoints.
Get a simple overview per ship
Our assessment tool creates
a simple to
rating for your ship's carbon
intensity.
IMO compliance self-assessment and forecasting
IMO MARPOL Annex VI measures require ships to reduce their carbon intensity by 40% by 2030 and 70% by 2040 to meet the passing grade.
| Ship Grade | CO2 Emission Boundary |
|---|---|
| A | Superior bound |
| B | Lower bound |
| C | Required CII range |
| D | Upper bound |
| E | Inferior bound |
Forecast retrofitting dates
Quickly assess when your ship will need to be
retrofitted to meet the IMO's
to grade
requirements. The CII Calculator will show you the years in which
your ship will need to be retrofitted to meet the IMO's MARPOL Annex VI
requirements.
