WebFOCUS Report
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. Las cifras que se presentan en este reporte se estimaron conforme a la metodología usada en las comunicaciones nacionales a Naciones Unidas y corresponden a los datos de la Quinta Comunicación Nacional ante la Convención Marco de las Naciones Unidas sobre el Cambio Climático.
En la actualización de esta información hubo un cambi o metodológico importante, tanto en modelos utilizados por sector para la estimación de las emisiones, como en las fuentes de información utilizadas incorporando información de mayor detalle, de manera que la información más reciente disponible no es comparable con la que se presenta aquí como acervo histórico.
Las categorías de emisión están definidas por el Panel Intergubernamental sobre el Cambio climático (IPCC, por sus siglas en inglés). Los gases que se reportan son los incluidos en el Anexo A de l Protocolo de Kioto: bióxido de carbono (CO2), metano (CH4), óxido nitroso (N2O), hidrofluorocarbonos (HFCs), perfluorocarbonos (PFCs) 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 “A bandono de tierras 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.
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 se miaerobios, sitios no gestionados someros y profundos, y sitios no categorizados.
En la información adicional del INEGEI, la categoría "Aviación y navegación internacional (Bunkers)", contempla las aeronaves o embarcaciones que cargan combustible en el país, con destino final en el extranjero. Se estiman las emisiones pero 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.
