This source does not have an emissions factor for the selected pollutant. This is either because:
- that pollutant is not relevant for that source (e.g., there are no CO2 emissions associated with animal husbandry within SIMAP's system bounds);
- those emissions are calculated through another pollutant emissions factor (e.g., there is no eCO2 factor because there are already CO2, CH4, and N2O factors for a given source);
- the emissions factor applies to a custom source labeled as 'other' that requires the entry of a custom emissions factor; or
- the emissions factor should be 0 because there are no emissions within SIMAP's system bounds (e.g., renewable sources).
