| Methodology description | The Factor de Emisión del Sistema Eléctrico Nacional (FESEN) is the official Mexican grid electricity emission factor, published annually by the Secretaría de Medio Ambiente Recursos Naturales (SEMARNAT) based on data provided by the Comisión Reguladora de Energía (CRE). It represents the average CO₂e emissions per MWh of electricity delivered to the national grid, accounting for the full generation mix — including gas, hydroelectric, solar, wind, and other sources — from all power plants supplying the Sistema Eléctrico Nacional. The factor is used for mandatory Scope 2 indirect GHG reporting by establishments subject to the Registro Nacional de Emisiones (RENE). |
