Shipping currently accounts for 3.2% of anthropogenic CO2 emissions and its emissions are forecasted to increase 2-3 fold until 2050. While a significant potential exists to increase the efficiency of ships and thus reduce emissions, much of this potential is left untapped because of a lack of adequate incentives. The introduction of a global emissions trading scheme for shipping or a global emissions levy would provide the right incentive to make shipping contribute to the solution of the climate problem.
This report provides a full overview of climate issues for maritime transport. It shows: – Past, current and future CO2 emissions of shipping. – Current and future climate impact of shipping. – A comprehensive list of technical and operational measures to reduce emissions. – The costs and abatement potential of these options. – An assessment of policies to reduce the climate impact of shipping.
The report has been written by a consortium led by MARINTEK for the IMO. CE Delft was responsible for assessing costs and potential of technical and operational options to reduce emissions and for the policy evaluation.
