Crunching the Hydro Numbers 2010: First Quarter Update on the CDM

First published on


  • The number of projects that entered the CDM pipeline stayed the same between the fourth quarter of 2009 and the first quarter or 2010 (See Fig. 1).
  • The percent of hydropower projects entering the CDM pipeline relative to all CDM projects continues to be on a downward trend since 2007 (see Fig. 2).
  • The percent of projects rejected out of the total number of projects requesting registration was 7.4% in 2007, 3.8% in 2008, and 2.0% in 2009 (this does not include withdrawn projects). 2009 saw an increase in rejections due to heightened scrutiny by the CDM Executive Board.
  • The percent of registered projects that were involved in the review process (which includes projects that require corrections) has been growing over the years (see Fig. 4): 9.5% in 2005, 9.1% in 2006, 19.3% in 2007, 56.9% in 2008, 70.4% in 2009, 56.3% in 2010 (as of April). This is also likely the result of pressure by stakeholders for the CDM to review projects with questionable additionality and sustainability claims, and the CDM Executive Board’s response.
  • 46.6% of all hydro projects in the CDM pipeline have requested registration since 2004, while 41.5% of all hydro projects have actually been registered. Figs. 3 and 4 show the fate of projects requesting registration and being registered by year.
  • Hydro projects continue to be the most prevalent type of project in the CDM pipeline (28% of all projects). 71% of hydro projects are located in China (the distribution among regions has been largely unchanged). 66% of all CERs issued come from China as well. Figs. 5 and 6 are based on the UNFCCC CDM pipeline database, last updated on March 1, 2010.
