Atmospheric Monitoring, Reporting, and Verification (aMRV)

Atmospheric Monitoring, Reporting, and Verification or aMRV refers to climate-monitoring approaches that measure greenhouse gas concentrations and fluxes directly in the atmosphere rather than relying only on activity-based calculations or emissions estimates. These systems use technologies such as satellites, atmospheric sensors, eddy covariance towers, aircraft measurements, and remote sensing networks to track carbon dioxide, methane, and other greenhouse gases in near real time. aMRV is increasingly used in carbon markets, carbon removal projects, methane monitoring, and national climate reporting because it can provide independent validation of emissions reductions and carbon removals across large geographic areas.
