Scrubber: a potentially overestimated compliance method for the Emission Control Areas - The importance of involving a ship's sailing pattern in the evaluation
Gu, Yewen; Wallace, Stein W. (Discussion paper;13/17, Working paper, 2017-10-30)Different methods for sulphur emission reductions, available to satisfy the latest Emission Control Areas (ECA) regulations, may lead to different sailing patterns (route and speed choices of a vessel) and thus have ... -
The Impact of Bunker Risk Management on CO2 Emissions in Maritime Transportation Under ECA Regulation
Gu, Yewen; Wallace, Stein W.; Wang, Xin (Discussion paper;17/16, Working paper, 2016-11-16)The shipping industry carries over 90 percent of the world’s trade, and is hence a major contributor to CO2 and other airborne emissions. As a global effort to reduce air pollution from ships, the implementation of the ECA ...
