1、JUNE 2022WORKING PAPER 2022-20Decarbonizing Chinas coastal shipping:The role of fuel efficiency and low-carbon fuels Authors:Xiaoli Mao and Zhihang MengKey words:energy efficiency,China,coastal shipping,decarbonizationSummaryAt the 75th UN General Assembly in September of 2020,Chinese President Xi J

2、inping announced that Chinas overall carbon dioxide(CO2)emissions will peak by 2030 and that carbon neutrality will be reached before 2060(China Dialogue,2020).This is a huge commitment for China as the worlds largest emitter of greenhouse gases(GHG)in 2019(UCS,2022)and as the second largest economy

3、.One year later,China released an action plan designed to cap its CO2 emissions before 2030(National Development and Reform Commission(NDRC)Peoples Republic of China,n.d.).But the world is still waiting to learn what“carbon neutralization”means for the country,and what an action plan for reaching th

4、is target by 2060 will look like.Informing these goals is a study by the Institute for Climate Change and Sustainable Development at Tsinghua University(ICCSD),which offers insight into Chinas long-term,low-carbon development strategy and transition pathways(Tianjie,2020;ICCSD,2021).For the transpor

6、rm action plan for the shipping sector,the ICCT takes a first look at Chinas domestic coastal shipping sector and provides recommendations for actionable long-term decarbonization pathways designed to avoid exceeding its current share of transportation-sector CO2.Specifically,we used the sectors 201
