海运中的EFF是什么意思？

EFF：New Environmental Fuel FeeEffective from 1st December 2019, Maersk will introduce a Environmental Fuel Fee (EFF) on all trades, which will apply to all spot business and contracts with validity up to 3 months.从2019年12月1日起，马士基将对所有行业征收环境燃油费（EFF），该费用将适用于所有现货业务和有效期不超过3个月的合同。The EFF tariff will be trade-specific and reflect the fuel-related cost increases that result from compliance to the IMO 2020 regulation (calculated as the price difference between high sulphur fuel and low sulphur fuel multiplied by a trade factor).EFF关税将针对特定贸易，并反映因遵守IMO 2020法规而导致的与燃料相关的成本增加（计算方法为，高硫燃料和低硫燃料的价格差乘以贸易系数）。

The EFF tariffs will only be reviewed in case of significant fuel price fluctuations (more than 50 USD/ton).仅在燃料价格出现重大波动（超过50美元/吨）的情况下，才对EFF关税进行审核。

The EFF tariffs applicable from 1st December 2019 will be announced end-October 2019.从2019年12月1日起适用的EFF关税将在2019年10月底宣布。

上面提到的IMO 2020 regulation，

From 1st January 2020, a new regulation will come into force to reduce air pollution from ships globally. Whereas today ships can use fuel with up to 3.5% sulphur content (outside Emission Control Areas), the new global sulphur cap will be 0.5%.从2020年1月1日起，一项新法规将生效，以减少全球船舶的空气污染。
