Search Emission Metrics

This tool returns emission metrics associated with your query. An emission metric is an estimate of a quantity of pollutant emitted within defined geographic, temporal, sectoral, and/or procedural boundaries. Air pollutant inventories, including those found in this Portal, typically feature the following parameters: Place (country or state/province/territory); Year (or range of years); Pollutant (or pollutant family); Source Category (or subcategory); and Estimation Methodology. Note: Fuel (another key parameter) is not included at this time, because it is not well-defined in the available inventories.

The parameters included in each inventory are shown in the Inventory Overview table below.

Select from the parameters below to refine your search. To ensure that your query returns results, refer to the Inventory Overview table to select parameters that are compatible with one another. Note: When selecting a Source Category or Estimation Methodology, we recommend that you click on the “i” icons for more information.

México Quinta Comunicación Nacional ante la Convención Marco de las Naciones Unidas sobre el Cambio Climático

Instituto Nacional de Ecología y Cambio Climático
December 2012

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).

Global Warming Potential (GWP) is an index that attempts to integrate the overall climate impacts of a specific action (e.g., emissions of CH4, NOx or aerosols). It relates the impact of emissions of a gas to that of emission of an equivalent mass of CO2.
