LNG carrier player GasLog has revealed an increase in its carbon intensity for 2022 as it was forced to use less LNG as a fuel.

The Peter Livanos-controlled shipowner said in its latest sustainability report that total CO2 emissions actually decreased last year, mainly because of the partial operation of two vessels as floating storage units (FSUs).

“However, worldwide port congestion and lower usage of LNG as fuel, instructed by our charterers, changed the fleet’s operating profile and had a direct negative impact on our AER [annual efficiency rating], which increased,” GasLog added.
