石油设备网讯 据世界石油网站5月17日报道，国际海事组织（IMO）周五同意对某些类型的船舶制定更严格的能效目标，以加快采取行动减少该行业的排放。
国际海事组织的海洋环境保护委员会本周在伦敦召开会议，讨论更严格的硫排放规则以及其他措施，以实现到2050年将温室气体排放量从2008年水平削减50%的长期目标。
国际航运业约占全球二氧化碳排放量的2％，这是导致全球变暖的主要温室气体。
根据国际海事组织的能源效率设计指数(EEDI)，该组织为新船设定了强制性目标，规定不同船型和大小的船只在提供相同运输量的前提下，所允许的最大二氧化碳排放量。
该协议草案显示，到2022年，新集装箱船的效率将提高50％，而之前的目标是到2025年效率提高30％。
到2022年，新型通用货船、天然气和液化天然气运输船以及混合柴油电力游轮的效率也必须提高30%。
国际清洁运输委员会(ICCT)表示，此举将在2022年至2050年间减少7.5亿吨二氧化碳排放，相当于同期国际航运总排放量的2%左右。
ICCT海洋项目主任Dan Rutherford表示，“国际海事组织决定提高并加强一些新船的能效目标，这是应对气候变化的一个适度但必要的步骤。”
然而，一些环保人士表示，目前建造的一些效率最高的船只已经超过了目标，应该制定更严格的目标。

IMO agrees on stricter efficiency targets for some ships
The International Maritime Organization (IMO) on Friday agreed stricter energy efficiency targets for certain types of ships in an effort to speed up action to cut the sector’s emissions.
The IMO’s Marine Environment Protection Committee has been meeting in London this week to discuss tougher rules on sulfur emissions and other measures towards meeting a long-term goal of cutting greenhouse gas emissions by 50% from 2008 levels by 2050.
The international shipping sector accounts for about 2% of global carbon dioxide (CO2) emissions, the main greenhouse gas blamed for global warming.
Under its Energy Efficiency Design Index (EEDI), the IMO set mandatory targets for new ships on the maximum amount of CO2 emissions allowed for different vessel types and sizes to provide the same amount of transportation.
A draft of the agreement shows that new container ships will now be required to be up to 50% more efficient by 2022, compared with the previous target of up to 30% more efficient by 2025.
New general cargo ships, gas and liquefied natural gas (LNG) carriers and hybrid diesel-electric cruise ships will also have to be up to 30 percent more efficient by 2022.
The International Council on Clean Transportation (ICCT) said the move could reduce CO2 emissions by about 750 million tonnes from 2022 to 2050, equating to around 2% of all emissions from international shipping over that period.
“The IMO’s decision to move up and tighten energy efficiency targets for some new ships is a modest but necessary step to combat climate change,” said Dan Rutherford, ICCT’s marine program director.
However, some environmental campaigners said the target is already being beaten by some of the most efficient ships being built today and stricter goals should be set.
