Sectoral mechanisms: Will it be a piece of cake?

The purpose of this report is to assess potential emissions reductions from four different sector approaches that are currently being debated in the international climate negotiations: i) sector commitments, ii) sector crediting mechanism (SCM), iii) Nationally Appropriate Mitigation Actions (NAMAs) and iv) CDM with standardized baselines. These are compared to the CDM as we know it today with project-based baselines.
