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.
