海运产生的二氧化碳排放量占全球温室气体总排放量的很大一部分。根据国际海事组织(2009年第二份海事组织温室气体研究报告)的数据，2007年海运排放了1.046亿吨(所有吨都是公吨)的二氧化碳，占世界二氧化碳排放总量的3.3%。国际海事组织(海事组织)目前正在讨论减少航运温室气体排放的技术措施和基于市场的措施。本文研究了减速对海上运输的直接排放量和成本的影响，为便于对世界船队进行汇总，选择了船级。结果表明，减少航运中的二氧化碳排放有很大的潜力。负减排成本(成本最小化)可以减少19%的排放量，零减排成本可以减少28%的排放量。由于这些减排纯粹是基于较低的速度，它们现在可以在一定程度上实现。(C)2011爱思唯尔有限公司。保留所有权利。
CO2 emissions from maritime transport represent a significant part of total global greenhouse gas (GHG) emissions. According to the International Maritime Organization (Second IMO GHG study, 2009), maritime transport emitted 1046 million tons (all tons are metric) of CO2 in 2007, representing 3.3% of the world's total CO2 emissions. The International Maritime Organization (IMO) is currently debating both technical and market-based measures for reducing greenhouse gas emissions from shipping. This paper presents investigations on the effects of speed reductions on the direct emissions and costs of maritime transport, for which the selection of ship classes was made to facilitate an aggregated representation of the world fleet. The results show that there is a substantial potential for reducing CO2 emissions in shipping. Emissions can be reduced by 19% with a negative abatement cost (cost minimization) and by 28% at a zero abatement cost. Since these emission reductions are based purely on lower speeds, they can in part be performed now. (C) 2011 Elsevier Ltd. All rights reserved.
