For the first time, a commercial vessel has a sensor capable of measuring in real time the emissions of black carbon, one of the most harmful pollutants in shipping. The technology was installed on the Falstria Swan, a vessel operated by Uni-Tankers, as part of the Cleanship Project. This multidisciplinary collaboration brings together the Danish Technological Institute, Green Instruments and several naval entities with the aim of decarbonize the maritime industry.
An emission sensor with measurement accuracy
The sensor developed by Green Instruments provides accurate data on soot particles emitted by engines during actual offshore operations. This capability is essential in view of the imminent arrival of stricter regulations by the IMO and the European Union to reduce black carbon emissions. black carbon emissionsemissions, which account for about 20 % of the total CO₂ equivalent in international shipping.
Funded by the Danish Environmental Protection Agency with 18 million kroner, Cleanship seeks evidence on the performance of new technologies, including biofuels. biofuelsThis data-driven insight will enable shipping companies to make more effective decisions in the face of new technologies, including biofuels, engine performance optimization and reduced energy consumption. This data-driven insight will enable shipping companies to make more effective decisions in the face of climate change.
Green Instruments’ contribution to broader monitoring
In addition to the soot sensor, the Green Instruments CEMS system measures gases such as CO₂, CH₄ and N₂O. The collected data is converted into operational indicators using GreenView Emissions Insight software, providing reports compatible with regulations such as the ETS and the EU fuel system.

Real-time data enables shipping companies to move beyond decisions based on estimates. They can now accurately identify which onboard practices or technologies reduce emissions. This approach anticipates regulatory requirements and represents a tool for improving operational efficiency and sustainability.
