Carbon credits are issued only after a project quantifies its climate outcome through monitoring, reporting and verification, usually shortened to MRV. Each stage has a distinct purpose.
Monitoring
The project collects the parameters required by its methodology. A biochar facility may record feedstock, energy use, production conditions and laboratory results. A soil carbon programme may combine farm activity data, sampling and model outputs. A refrigerant project records recovered gas, storage, transport and destruction.
The monitoring plan defines instruments, frequency, calibration, quality controls and record retention before the first monitoring period begins.
Reporting
The project converts raw data into a monitoring report. It explains calculations, deviations, missing data, uncertainty and the final quantity requested for issuance.
A good report is traceable. An auditor should be able to move from the headline tonnes back through equations, source files and operational records.
Verification
An independent validation and verification body reviews the report against the registered project design and methodology. The auditor tests samples, recalculates results, examines controls and may conduct site visits.
Findings are resolved before the verifier issues an opinion. The registry then reviews the verification package and, if accepted, issues serialised units.
Validation is different
Validation happens before registration and asks whether the project design is eligible and capable of producing legitimate outcomes if implemented. Verification looks backward at what actually occurred.
Digital MRV
Sensors, remote sensing, mobile data and automated pipelines can improve coverage and reduce manual error. Technology does not remove the need for methodology discipline, data governance and independent assurance.
Sentinel Earth designs MRV with operations in mind, from batch-level biochar data to plot-level agricultural monitoring and end-to-end refrigerant tracking.
