NOTAS DE LA VARIABLE

Emisiones de gases de efecto invernadero El Inventario Nacional de Emisiones de Gases de Efecto Invernadero (INEGEI) comprende las estimaciones de las emisiones por fuentes y sumideros. Estas cifras remplazan las reportadas previamente, en la Cuarta Comunicación Nacional ante la Convención Marco de las Naciones Unidas sobre el Cambio Climático (CMNUCC), ya que incluyen información actualizada y correcciones en la metodología.
Las categorías de emisión están definidas por el Panel Intergubernamental sobre el Cambi o climático (PICC). Los gases que reporta el Inventario, son los incluidos en el Anexo A del Protocolo de Kioto: bióxido de carbono (CO2), metano (CH4), óxido nitroso (N2O), hidrofluorocarbonos (HFC), perfluorocarbonos (PFC ) y hexafluoruro de azufre (SF6).
Las emisiones de este inventario se expresan para cada contaminante en unidades de CO2 equivalente, los cuales se estiman multiplicando la cantidad de emisiones de cada gas por su valor de potencial de calentamiento. Potenciales de calentamiento: CO2=1, CH4=21, N2O=310, HFC entre 2800 y 11700, PFC entre 6500 y 9200, y SF6=23900; valores que son estimados en un horizonte de 100 años.
La categoría Energía incluye las emisiones que son resultado de la exploración, producción, transformación, manejo y consumo de productos energéticos.
En la categoría Cambio de Uso de Suelo y Silvicultura, se reportan las absorciones (dado que éstas representan lo contrario a “emisiones”, se presentan en números negativos), en el concepto de “Abandono de tierr as agrícolas”, lo que se traduce en revegetación del suelo.
Las emisiones de CO2 por quema de biomasa están contempladas en las categorías Agricultura, Cambio de Uso de Suelo y Silvicultura; se publica como información adicional para conocer la cantidad que se utiliza de biomasa como energético.
La categoría Transporte Internacional Aéreo y Marítimo (Bunkers), contempla las aeronaves o embarcaciones que cargan combustible en el país, con destino final en el extranjero. Se estiman las emisiones pe ro no se consideran emisiones nacionales. Están a cargo de la CMNUCC, a través de la “International Civil Aviation Organization (ICAO) Y “The international Maritime Organization (IMO)”, para realizar medidas de mitigación.
En este inventario para la categoría Desechos se empleó la información relativa a la cantidad y tipo de desechos sólidos eliminados en sitios gestionados anaerobios y semiaerobios, sitios no gestionados someros y profundos, y sitios no categorizados.
