| 摘要： | Shipping is responsible for around 3% of global carbon emissions, according to the 4th IMO greenhouse gas (GHG) study. This share needs to be reduced, however, there are three major issues, among many others, which make shipping a hard-to-abate sector. First, there is a large installed base of engines with single-fuel technology. Although single-fuel engines can be operated on net-zero fuels, such as certain biofuels, coupled with the limited availability, price level, and possible sustainability issues, it becomes an indirect challenge. Second, adding to the fleet issue is the outlook to 60% growth in deadweight tons (dwt) by the mid-century, bringing the total fleet from 3.1 billion dwt in 2022 to an expected 5.1 billion dwt in 2050. While energy efficiency may increase, we can factor in an expected increased energy demand of 50-60% in comparison to today. |
