Slow steaming for LNG carriers in an effort to meet the International Maritime Organization’s carbon intensity reduction targets will result in higher global CO2 emissions, according to a study by consultants Rystad Energy.

The consultant said the saving in CO2 emissions from limiting the speed of steam-turbine and slow-speed diesel LNG carriers to 15 knots will be dwarfed by the pollution from gas-to-coal switching that the move would cause in Asia.
