| Abstract: | The International Maritime Organization (IMO) promotes global “green shipping” through rule-making in accordance with its mandate under the Kyoto Protocol. The IMO rules related to reduction in greenhouse gas emissions can be divided into two types: technical and operational measures; and market-based measures. As to the former, important regulations have been adopted that are mandatory for ships irrespective of their flag. The latter are still in the drafting process, and in view of deep divisions between member states, it will be difficult to reach early agreement. In the development of rules for emissions reduction in IMO, the common but differentiated responsibility principle (CBDR) conflicts severely with the non-discrimination principle which has long been a traditional and basic principle of IMO regulation. Considering the peculiarities of the shipping industry, a fuller understanding of CBDR will be necessary in order to find a reasonable and feasible way to reconcile these two principles. |
