México Quinta Comunicación Nacional ante la Convención Marco de las Naciones Unidas sobre el Cambio Climático
As a non-Annex I Party to the United Nations Framework Convention on Climate Change (UNFCCC), Mexico submits a National Communication, an national inventory of greenhouse gas emissions and sinks, to the UNFCCC as capacities permit. Since 1997, Mexico has submitted five National Communications to the UNFCCC. The inventories are published by the Secretaría de Medio Ambiente y Recursos Naturales (SEMARNAT) and the Instituto Nacional de Ecología y Cambio Climático (INECC).
This inventory uses source categories defined by two guidance documents: the Common Reporting Format (CRF) source categories defined by the Updated UNFCCC reporting guidelines on annual inventories following incorporation of the provisions of decision 14/CP.11 memorandum, and, for Waste, source categories defined by the 2006 IPCC Guidelines for National Greenhouse Gas Inventories.
Totals reflect net emissions (the sum of all sources minus the sum of all sinks).
