中文简介：

CII（碳强度指标）是一个运营指数，它必须在每个日历年的年底根据航行的海里和排放的二氧化碳来计算。碳强度将温室气体的排放与所运货物的数量和航行距离联系起来。达到现如今国际海事组织（IMO）规定的碳排放的主要选择是：降低速度、优化船体、提高船舶利用率、性能监测、增加运力、引进节能设备、改善水动力、船体涂层、船体清洁、CFD（计算流体动力学）、创新节能技术、电池和燃料电池以及/或新燃料。

English introduction：

CII is an operational Index which has to be calculated at the end of each calendar year based on the nautical miles sailed and CO2 emitted. Carbon intensity links the GHG emissions to the amount of cargo carried over distance travelled. The main options to meet the Required CII are: speed reduction, trim optimization, ship’s utilization, performance monitoring, capacity increasing, introduction of energy efficient consumers, hydrodynamic improving, hull coating, hull cleaning, CFD, innovative energy efficiency technology, batteries and fuel cells, and/or new fuels.
