Mexico has developed a comprehensive national Measurement, Reporting, and Verification (MRV) framework aimed at supporting its transition to a low-carbon economy, driven by legislation and policies mandating emission tracking and evaluation. The framework includes a range of mechanisms such as national emissions registries and a voluntary greenhouse gas (GHG) reporting program, enhancing institutional capacities and decision-making processes. Success factors include strong political support, incorporation of indicators in policy-making, and the integration of MRV from the beginning of climate strategy design.
