In the light of an uncertain post-2020 climate regime, possibilities for the incremental transition from market-based mechanisms such as the Clean Development Mechanism (CDM) to various forms of a new market mechanism (NMM), domestic Emissions Trading Schemes (ETS) or domestic Non-ETS instruments such as Nationally Appropriate Mitigation Actions (NAMAs) become ever-more relevant. In their research project, "Opportunities for a stepwise transition from CDM towards NMM and emissions trading and the respective capacity building needs", Perspectives GmbH and adelphi outline possible options for the successful transition from CDM activities towards such future climate policy instruments for the German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB).
