ABSTRACT: As global warming caused by greenhouse gases grows (GHGs) into a global
environmental threat, carbon dioxide emissions are drawing increasing attention
in these years. Among all emission sources, transportation is a major
contributor to climate change because of its high dependence on fossil fuels.
The International Maritime Organization (IMO) has therefore been promoting the
reduction of fuel usage and carbon emissions for container ships by such
measures as improving shipping route selection, shipping speed optimization,
and constructing clean energy propulsion systems. In this paper, a review of
the impact of carbon dioxide emissions on climate change is presented; the
current situations of carbon dioxide emissions, decarbonizing methods, IMO
regulations, and possible future directions of decarbonizing in the maritime
transportation industry are also discussed. Based on the result, it is
found that in the case that non intelligent ships still occupy the vast
majority of operating ships, the use of new energy as the main propulsion fuel
has the defects of high renewal cost and long effective period. It is more
likely to achieve energy conservation and emission reduction in the shipping
industry in a short period of time by using intelligent means and artificial
intelligence to assist ship operation.
