The research project seeks to identify the CDM SD tool's possible shortcomings, and to make structured recommendations on how to improve the EB's SD tool. Findings from this project are meant to have a lighthouse effect on the development of provisions on Sustainable Development within other carbon mechanisms of the UNFCCC and beyond. This report represents the consolidated findings of three work packages within this research project. The first chapter provides some background on the subject at hand, and leads into the report. The following chapter covers the assessment and comparison of the SD provisions of selected flexible mechanisms and multilateral standards.
