Is slow steaming a sustainable means of reducing CO_2 emissions from container shipping?

摘要

Slow steaming strategies have been implemented by most shipping lines and significantly reduce CO_2 emissions from international shipping. This article measures the rate at which CO_2 emissions have been reduced for various container trades and estimates the bunker break-even price at which this strategy is sustainable in the long run. It is found that shows such reductions can only be sustained given a bunker price of at least $350-$400 for the main container trades.
