Can CDM monitoring requirements be reduced while maintaining environmental integrity?

Abstract

Monitoring, reporting, and verification (MRV) requirements in the Clean Development Mechanism (CDM) are perceived to be of high quality, but also complex and stringent. Only one-third of the registered projects successfully managed initial verification and already received carbon credits. The time required to achieve first issuance remains high despite considerable improvements in other CDM project cycle steps. This leads to the question of whether MRV provisions in the CDM represent barriers that could be lowered while ensuring the CDM's integrity. The CDM requirements are compared with the MRV provisions of the EU Emission Trading System (EU ETS). The comparison shows that CDM–MRV provisions are often stricter and less flexible compared to similar provisions in the EU ETS. Due to structural differences between the EU ETS and the CDM, some different MRV approaches are justified and reflect the CDM's disparate objectives and complexity. It is found that some CDM provisions result in barriers which seem avoidable and do not contribute to the CDM's environmental integrity. Recommendations are made for CDM-specific improvements and general structural changes to improve cost-efficiency and reduce uncertainty with relevance to policy developments around future market mechanisms.
