Key Relationships

Inventory (0..*)

A Pollutant will relate to each Inventory that includes reporting of the pollutant.  This relationship defines the pollutant boundary of the Inventory.

GwpValue (0..*)

Within the graph of a GHG Inventory, each Pollutant object will relate to a single GwpValue object.

EmissionMetric (0..*)

Within the graph of a GHG Inventory, each Pollutant object may relate to multiple EmissionMetric objects, including both atomic EmissionMetric objects reporting emissions for a specific combination of Pollutant, SourceCategory, EstimationMethodology, and geographic boundary, and additive emission metric objects reporting pollutant-specific emission totals for a SourceCategory, or an entire Inventory.

EstimationMethodology (0..*)

A Pollution object will relate to each EstimationMethodology that estimates the emission or removal of the Pollutant.


A Pollutant object is a static dimension of unchanging information intended to be reused by multiple inventories.
