在上周举行的国际海事组织（IMO）海上环境保护委员会第80届会议（MEPC 80）上，与会代表通过了2023年船舶温室气体减排战略。以下是2023减排战略的核心重点：

①减排目标：尽快达到国际海运温室气体（GHG）排放的峰值，在接近2050年前后达到净零排放。考虑到不同国情，努力通过愿景中提出的，与《巴黎协定》第二条规定的长期气温目标一致的减排路径，逐步消除海运温室气体排放。

②指示性校核点：到2030年，国际海运温室气体年度排放总量比2008年至少降低20%，并力争降低30%；到2040年，国际海运温室气体年度排放总量比2008年至少降低70%，并力争降低80%。

③替代能源和技术：到2030年，国际海运中采用的零/近零温室气体排放技术、燃料或能源使用占比至少达到5%，并力争达到10%。

Last week’s meeting of the International Maritime Organization’s Marine Environmental Protection Committee  (MEPC 80)saw member states adopt the 2023 IMO Strategy on Reduction of GHG Emissions from Ships. Here are the emphasis of 2023 IMO GHG Strategy:   

①LEVELS OF AMBITION: To peak GHG emissions from international shipping as soon as possible and to reach net-zero GHG emissions by or around, i.e., close to, 2050, taking into account different national circumstances whilst pursuing efforts towards phasing them out as called for in the Vision consistent with the long-term temperature goal set out in Article 2 of the Paris Agreement.

②INDICATIVE CHECKPOINTS: To reduce the total annual GHG emissions from international shipping by at least 20%, striving for 30%, 

by 2030, compared to 2008; and to reduce the total annual GHG emissions from international shipping by at least 70%, striving for 80%, 

by 2040, compared to 2008.

③TECHNOLOGIES, FUELS, ENERGY SOURCES: Uptake of zero or near-zero GHG emission technoloqies, fuels and/or energy sources to represent at least 5%, striving for 10%, of the energy used by international shipping by 2030.
