Ship fuel tax will bring down the speed
A US$60 per tonne fuel tax could lead to a decrease in carbon dioxide (CO2) emissions of up to 20 per cent, according to a new study led by James Corbett of the University of Delaware. A higher fuel tax of around US$150 per tonne could lead to an average speed-related CO2 reduction of up to 30 per cent.
A speed reduction mandate targeted to achieve 20-per-cent CO2 reduction in the container fleet is shown to cost between US$30 and 200 per tonne of CO2 abated, depending on how the fleet responds to a speed reduction mandate.
