Here is IETA's input to the UNFCCC on the review of the CDM modalities and procedures. This call for input was issued by the SBI at COP 19/CMP 9 in Warsaw (UNFCCC document available here) and asks for technical advice and guidance on a few particular elements of the CDM modalities and procedures. 

IETA has responded to each query on the modalities and procedures, and our underlying message is to not undermine confidence in the market and to strengthen opportunities for project participants and investors in the CDM.
