This paper offers a preliminary analysis of several scenarios for integration of sectoral approaches in international and national climate policy.
We consider four broad types of sectoral approaches:
• A global action, i.e. a unilateral move by industry to foster GHG improvements
• A global agreement between industry and Parties to the UNFCCC
• A series of national policies targeting a sector, with some intergovernmental co-ordination
• A sectoral crediting mechanism whereby reductions recorded at a sector level may be eligible for emission credits
