New concepts under the Clean DevelopmentMechanism (CDM), namely standardized baselines andsuppressed demand, should facilitate the implementation ofCDM energy access projects, particularly in Least DevelopedCountries (LDCs), by reducing transaction costs andreflecting the real emission reductions achieved.Governments and authorities in LDCs can play a prominentrole in making these new CDM opportunities available. Theimprovement of the regulatory framework can facilitate thedevelopment of innovative carbon-based financing schemesrequired for successful scaling-up of CDM energy accessprojects in LDCs. The main purpose of this paper is tooutline how the new CDM concepts of standardized baselinesand suppressed demand may be used to promote energy accessprojects under the CDM, in the context of new and expandedrole of host country Designated National Authorities (DNAs).In the process, the paper also identifies challenges in theuse of these concepts and opportunities for furthersimplification. By way of illustration, one specific energyaccess technology, solar home systems, is analyzed indetail. The paper is organized as follows: chapter one isintroduction; chapter two provides an overview of thecurrent status of CDM projects in LDCs; chapter threeintroduces energy access projects in LDCs; chapter fouroutlines new approaches under the CDM for energy accessprojects; chapter five goes into the challenges for theapplication of standardized baselines in LDCs; and chaptersix gives recommendations on implementing the new CDM concepts.
