Open Emission

THE WHY

Cutting emissions starts with understanding them. EU MRV analysis has been possible since 2018, when the regulation began publishing millions of data points on ship emissions. but that raw data is hard to use.

A ship's true performance is more than just its total emissions. You need to compare it to its true peers, track its year-on-year improvement, and understand what its future might look like under the new CII rules. The same approach works for operators, comparing their entire fleet's performance against similar companies.

Open Emission takes complex, public EU MRV data and turns it into ship emission intelligence you can actually act on — the story behind the numbers, and where you stand in it.

THE DATA

Since 2018, ships calling at European ports have reported their fuel use and emissions under the EU MRV regulation. This public dataset is the foundation for every maritime emissions analysis we produce.

THE METHOD

We apply machine learning algorithms to EU MRV data for ship emission analysis.

Peer grouping uses clustering techniques to identify genuinely comparable vessels based on type, size, and age. Life-linear regression measures how each ship's carbon intensity is changing over time. Cosine similarity finds operators running similar fleets.

The output is ship emission intelligence: statistical analysis, openly documented and reproducible from the public EU MRV records.

THE OUTPUT

Following are some of the deep insights that we get.

Peer Benchmarking

Where each ship's emission pattern sits among its true peers — vessels of similar type, size, and age.

Operator Score

Where each company's emission pattern sits among operators running similar fleets.

Ship Rankings

Statistical performance positioning across the entire EU MRV fleet, segmented by type.

Voyage Analysis

The breakdown of where a ship's emissions actually occur — at sea, on international legs, or at berth.

CII Projection

A simplified CII projected forward to 2030. The year each ship is likely to slip from C to D or E.

Year-on-Year Trend

The change in a ship's emission pattern compared to the change among its peers.

Fleet Overview

A snapshot of each operator's fleet. The focus is on the share of emissions coming from D and E rated ships — because that is where the real decarbonisation effort needs to go.
