| Since the Industrial Revolution in 18 century, global economy has kept a rapid development tendency. As its derived demand, shipping industry has seen a quite strong growth, accompanied by shocking environmental problems including global warming it aroused. Therefore, how to reduce carbon emission in shipping industry turns to be substantially urgent. Meanwhile, when it comes to the second half of 20 century, ships becomes larger and larger, especially among the containerships, crude tankers and dry bulkers. Due to the advanced technologies and shipbuilding methods, large vessels turns to be more compatible with the concept of low-carbon shipping. Based on these, this thesis wants to discuss the influence which larger ships put on the carbon reduction of shipping industry.There are two objectives of this thesis. First is to see whether larger ships could bring carbon reduction of global fleet, if yes, how is the effect. Second is how much is the abatement cost, whether it is cost-effective. Based on former researches, this thesis established a abatement cost leading model with four sub-models. Establishing normal fleets and EOS fleets, comparing its results to see carbon reduction and abatement cost of larger ships.About the empirical analysis part, this thesis focuses on the global dry bulker fleet, crude oil tankers and containerships fleet list on Clarkson Database, until April 2015. The conclusion shows that emissions can be reduced by as much as 22% with a negative abatement cost. Larger ships could bring emission reduction remarkably and it is cost-effective.Last but not least, based on all the above conclusions, recommendations are put forward to shipping emission reduction of China. On account of our national conditions, this thesis offers proposals to administration departments of shipping industry. Draw conclusions and respects in the end. |
