从表9可以看出，据估计，从引进的EEDI和SEEMP，二氧化碳排放量到2020年的将减少高达200万吨，到2030年将达到4.2亿吨。换句话说，与通常[3]相比，二氧化碳排放量到2020年将减少10-17％，到2030年将减少19-26％。此外，EEDI和SEEMP到2020年将节省200-800亿美元的燃料成本，到2030年将节省900-3100亿美元。

By the adoption of technical and operational measures, IMO became the first [4] international organization which made a successful regulatory regime for the reduction of GHG emission. Considering this research topic on shipbuilding industry, only EEDI will be examined in the next section.

通过采取技术和业务措施，国际海事组织成为了第一个成功制定减少温室气体排放的监管制度的国际组织。考虑到本课题的研究对造船业，仅在下一节探讨EEDI。

能效设计指数

The adoption of EEDI will severely affect the ship design to save fuels or reducing GHG emissions. It needs to review the detailed reason why the EEDI can influence shipbuilders. The detailed EEDI calculation formula is complex and the simplified EEDI formula is as follows.

采用EEDI将对船舶节省燃料设计和减少温室气体排放量产生有效影响。EEDI可以影响到造船的详细的原因的值得探讨。详细的EEDI计算公式复杂，简化EEDI公式如下。

(g/ton?mile)

EEDI indicates the efficiency that is expected for a ship to achieve, based on the ship specifications, calculated by engine power, specific fuel cost, deadweight and speed. The lower value of EEDI means the better efficiency. The transport work can be obtained by doing multiplication of deadweight of a ship and ship’s speed. According to the type of ship and size the amount of CO2 emission will change. Also, technology potentials could contribute the index of energy efficiency.

通过计算发动机输出功率，燃油成本，载重量和速度等船舶的规格，EEDI阐明了船舶将实现的预期。 EEDI的较低值表示较好的效率。运输工作可以做船舶和船的速度载重吨的乘法来获得。根据船的类型和尺寸来调整二氧化碳排出量。此外，技术潜力有助于提高能源效率的指标。

As illustrated in Figure 13, the EEDI requires that CO2 emission should be dropped by 30%. In the first phase (2015-2019), ships applied EEDI should reduce 10% of the reference line which could be calculated by MARPOL Annex VI. In the second phase (2020-2024), those ships should reduce 20% of the reference line. In the last phase (after 2025), emissions should be cut further 10% of the second phase (Altenburg, 2011).

如图13所示，EEDI需要二氧化碳排放量减少30%。在第一阶段（2015-2019），应用EEDI的船舶应在原基础上减少10%，参考线来自MARPOL公约附则VI。在第二阶段（2020-2024），这些船舶应在原基准线上减少20%。在最后阶段（2025年之后），排放量应由第二阶段进一步减少10%（Altenburg，2011）。
