Including a review mechanism (or sunset clause) would facilitate subsequent changes. In cases in which the decisions that established existing institutions already provide for review mechanisms, it may be useful to provide guidance on further review of interlinkages between such institutions in the future. Table 11 (below) provides an outline summary of characteristics of the current proposal for continuing with existing international institutions. It will take time to assess effectiveness of planning. Nevertheless, there are specific proposals included in the Geneva text for new international institutions as options to enhance adaptation (as well as a proposed option to have no new institutional arrangements for adaptation). The proposals for new institutional arrangements are for: a subsidiary body for adaptation, an adaptation registry, an international clearing house and registry, and a global knowledge platform.
