An important innovation with which the Clean Development Mechanism assists host countries in achieving sustainable development is its long-term approach to development. The emission reductions from CDM projects will have to be verified by an independent “operational entity” for as long as 21 years. The PCF contract with the West Nile company runs through 2017. Thus, a regular review and veri- fication of the project’s technical, commercial and emission-reduction performance is critical for a successful commercial relationship with any carbon buyers.
