REFRIGERANTS

A strong progress was made in reducing refrigerant-related emissions in 2024, supported by the rollout of ultrasonic leak detection systems across the fleet. This positive trend was not maintained in 2025. Refrigerant use increased significantly compared to previous years, driven by a number of operational factors.

One vessel experienced a leakage in the gas plant, which has since been repaired, but resulted in a substantial loss of refrigerant. In addition, maintenance activities on gas plants across several vessels required additional refrigerant use.

Furthermore, also changing cargo from LNG to ethylene, requires the use of the cargo refrigeration compressor. For one of our ships this operational change led to replacement of refrigerants during the year. As a result of these combined factors, total refrigerant use increased to almost three times the previous level, with associated CO₂-equivalent emissions increasing by a factor of 3.3.

While these increases are primarily linked to specific incidents and operational changes, they underline the importance of continued focus on leak prevention, maintenance and system optimisation. We remain committed to reducing refrigerant emissions and will continue to monitor performance closely and implement measures to limit losses where possible.
