Revelle™ by Wilhelmsen
Real-time, correct, and verified fuel and emission data
Pioneering direct CO₂ & CH₄ measurement for global shipping
We are working with a select group of partners to pioneer direct CO₂ and CH₄ measurement from onboard sensors to class verification to automating EU MRV/ETS input.
Our first installation has received DNV Statement of Compliance, and the full Revelle™ 3.0 platform will be ready for global deployment.
We provide direct, real‑time emission monitoring for ships, delivering verified emissions data accepted for EU MRV, ETS, IMO DCS and FuelEU reporting.
Generic IMO/IPCC emission factors, sludge losses, incomplete combustion, manual data entry errors, and engine variability all compound into a systematic bias.
The result: most operators calling European ports overreport CO2 emissions. calling European ports overreport CO2 emissions.
With EU ETS now applying a carbon price to every tonne of reported CO₂, that overreporting has a direct, measurable cost.

| Correct carbon tax | Better data for performance |
|
Revelle 3.0 system delivers actual CO₂/ CO4, estimated CO₂/ CO4 leading to correct EU ETS cost and correct CII rating. The system delivers traceability, calibration and maintenance. |
Reduce fuel consumption and lower emissions by giving your performance teams access to real-time data enabling shipowners and charterers to report the actual greenhouse gas emissions and fuel consumption to the mandatory regulatory frameworks. |

| Correct data for compliance | Deliver on sustainability goals |
|
Verified, audit-ready emission data integrated into your EU MRV and IMO DCS reporting systems. |
Accurate emissions data enables credible climate action. The system reduces operational burden and supports sustainable economic activity |
