CDM Watch Submission on the expansion of the usability of the small scale methodology AMS-III.AV “Low greenhouse gas emitting water purification systems”.  The new methodology SSC-III.AV in its current version will lead to a disproportionate generation of CERs that are not based on actual emissions reductions (suppressed demand). Although suppressed demand needs to be addressed, it has to be balanced and cannot be done in a way that seriously undermines the environmental integrity of CDM projects.
