Create an emission factor

Create your own custom emission factors if you don’t want to use the standard emission factors provided by the Unified content management application. An emission factor is a representative value that relates the quantity of a pollutant released to the atmosphere with the activity associated with the release of that pollutant.

Pourquoi et quand exécuter cette tâche

An emission factor is a coefficient that enables conversion of activity data into emissions. It’s the average emission rate of a given source, relative to the units of an activity or process. When you create an emission factor, you can select the unit from which you want to convert the data into the unit that you want to use to measure your emissions. For example, you can convert miles, which is the activity data, to the emissions the activity causes.

Procédure

2. Select New.
3. On the form, fill in the fields.

   Tableau 1. Emission factor form

   Field	Description
   Name	Name of the emission factor. For example, Cars-Mini-Diesel-miles-KgCO2e.
   From unit	Unit in which the data is collected.
   To unit	Unit to which the data must be converted.
   Emission activity	Emission activity or source of the factor.

4. Select Submit.

Résultats

• Two related lists are now available on the emission factor: 'Emission Factor Location', which was previously available and displays linked locations, and 'Calculated Metric Definition', a new addition that displays linked calculated metric definitions.
• You can now use this emission factor in a calculated metric definition.

• Add locations to an emission factor
  Add locations to an emission factor after you create the factor. The reason you must add locations to a factor is that an organization may have different locations and each location may have a different factor value for different periods.
• Recalculate emission factor
  When an emission factor value is updated, you can recalculate the emission factor to initiate the system to automatically recalculate the data for all linked calculated metric definitions (CMD), using the new value for dates within the emission factor's validity period. This ensures that metrics data remains consistent and accurate, reflecting the latest changes.
