The Comparisons of Speed Reduction with Other Policy Instruments in GHG Mitigation from Containerships

Greenhouse gas from ships has attracted increasing attention and speed reduction has been shown as one of potential approaches to substantially reduce ship-based CO2. The fundamental engineering and economic models are applied to evaluate the CO2 emission reduction effect and its marginal abatement cost under various policy scenarios. The models indicate that opportunity costs will be much lower if the speed reduction policy is mandated when fuel price is low compared to when fuel price is high. This paper provides a methodology to compare policy options and analyze their effects both from emission control and economic perspectives. The author shows how cap-and-trade and emission levy incentive speed reduction and achieve maximum emission reduction with minimum costs. It shows that a cap-and-trade market can decrease CO2 between 1% and 15%, less effective than mandated speed reductions. An emission levy of $150 per ton can reduce emissions up to 25%. These results are discussed in the context of policy-based choices for best approach to reducing ship-based emissions.
