Class: GasBreakdown

Constituent gas-level resolution of a line's emissions. Where a breakdown is provided it must be complete: the sum of gasCO2eContribution across entries equals the line's emissionsQuantityKgCO2e, within a small rounding tolerance (relative 0.1% with an absolute floor for near-zero lines). Any portion not attributable to a named gas is carried as an explicit OTHER entry rather than left implicit.

Slots

Name	Cardinality and Range	Description	Inheritance
gas	1 GasEnum `CO2` `CH4` `N2O` `HFC`: With subtype to be specified. `PFC` `SF6` `NF3` `OTHER`: Specified separately.		direct
gasQuantity	0..1 Float	Quantity of the gas in its native unit (e.g. tonnes CH4).	direct
gasCO2eContribution	0..1 Float	Portion of the line's emissionsQuantityKgCO2e attributable to this gas, as a non-negative magnitude. Where a breakdown is present, contributions sum to the line total (see class-level note).	direct
emissionOrigin	0..1 EmissionOriginEnum `FOSSIL` `BIOGENIC` `MIXED`: Origin cannot be disaggregated in the source data. `NOT_SPECIFIED`: Underlying data does not distinguish origin. `NOT_APPLICABLE`: Origin concept not relevant for this gas.	Origin of this gas's emissions. Where a gas breakdown is provided, gas-level origin takes precedence over the line-level emissionOrigin.	direct
