This document discusses the potential role of the Clean Development Mechanism (CDM) in supporting carbon dioxide capture and storage (CCS) projects. It provides an overview of the CDM and describes how a CCS methodology was submitted for approval but the CDM Executive Board decided CCS project eligibility requires agreement from COP/MOP. Methodological issues for CCS projects are discussed as well as the requirements for registering a CCS project under the CDM. The document argues that the CDM can help increase returns for CCS projects and attract financing by generating saleable emissions credits.
