The concept of Reducing Emissions from Deforestation and Forest Degradation (REDD+) has become a key debate of international cooperation on climate change. While most countries acknowledge the importance of so called community carbon benefits under REDD+ interventions, they are only just beginning the process of defining institutional arrangements for the sharing of economic benefits in REDD+. The Tanzanian Community Carbon Enterprise and UN-REDD+ models offer two examples of benefit sharing mechanisms which remains to be analyzed. The various actors and groups involved in designing these models have varying degrees of negotiation powers and diverse interests regarding the objectives, design and implementation of REDD+. This raises questions of institutional choices: how REDD+ benefit sharing mechanisms influences equity in forms of recognition of local representation and accountability of the non-governmental organizations to agrarian communities and in various levels of governance.
