The multi-step process to measure the amount of greenhouse gas (GHG) emissions reduced by a specific mitigation activity, such as reducing emissions from deforestation and forest degradation, over a period of time and to report these findings to an accredited third party.

Measurement – ‘Processes of data collection over time, providing basic datasets, including associated accuracy and precision, for the range of relevant variables. Possible data sources are field measurements, field observations, detection through remote sensing and interviews.’ (UN-REDD, 2009).

Reporting – ‘The process of formal reporting of assessment results to the UNFCCC, according to predetermined formats and according to established standards, especially the IPCC [Intergovernmental Panel on Climate Change] Guidelines and GPG [Good Practice Guidance].’ (UN-REDD, 2009).

Verification. – ‘The process of formal verification of reports, for example the established approach to verify national communications and national inventory reports to the UNFCCC.’
