Measurement, Reporting and Verification (MRV) of climate change mitigation activities is an essential part of the project cycle in all relevant carbon standards and particularly important to assure the accuracy and credibility of carbon credits.

Digital MRV is still a nascent field. This paper provides a snapshot of the state of activities, actors, opportunities, and barriers in the digital MRV space in two project types that are particularly important to current voluntary carbon markets: - technologies for decentralized energy provision (e.g. PV and cook stoves), as well as - carbon storage in forestry and agriculture.
