WHAT IS ADDITIONALITY IN CDM PROJECTS ?
GHG emissions from a CDM activity must be reduced below those that would have occurred in the absence of the projects. It must be shown that the project would not have been implemented without the CDM. Without this "additionality" requirement, there is no guarantee that CDM projects will create incremental GHG emissions reductions equivalent to those that would have been made in Annex I counties,or play a role in the ultimate objective of stabilizing atmospheric GHG concentrations.
