Fuel Properties

Last updated 19 days ago

Fuel Properties allows you to add calorific value and density information for the fuels used in your facilities, increasing the accuracy of greenhouse gas emission calculations.
With this feature, more accurate calculations can be made using real fuel characteristics.

To access this section:
Settings → Calculation Settings → Fuel Properties

Create New Fuel Property

To add a new fuel property, click the + Add New Fuel Property button on the page.
Follow the steps below in the form that appears:

Steps:

  1. Select Fuel Activity

Choose the fuel activity associated with the emission factor you will use.
This selection determines which emission factor the defined fuel will be linked to.
(Example: IPCC Natural Gas Commercial)

  1. Define the Emission Source

Enter a descriptive name for the fuel type in the Emission Source Name field.
(Example: “Natural Gas Used in the Facility”)

  1. Enter Calorific Value Information

Provide the calorific value (energy content) of the fuel.

  • Calorific Value Type:
    Select whether the value is in NCV (Net Calorific Value) or LCV (Lower Calorific Value).

  • Unit:
    Choose the appropriate unit (e.g., TJ/Gg, kcal/m³).

  • Value:
    Enter the calorific value you have.

  • Reference:
    Specify the source of the calorific value.
    (Example: “Laboratory Analysis”, “National Inventory Dataset”, “X Institution Measurement”)

  1. Enter Density Information

Enter the density value and its reference.

  • Value: Density value (e.g., 0.8 kg/m³).

  • Reference: Specify the source or measurement.
    (Example: “Defra Dataset 2023”, “Analysis Report”)

The density unit is fixed as kg/m³ in the system.

  1. Define Additional Information

  • Assessment Report Version (AR):
    Select the GWP (Global Warming Potential) report version to be used during calculations.
    (Example: AR4, AR5, AR6)

  • Target Units:
    Select the unit in which the fuel-related emission factor will be calculated.
    (Example: kWh, GJ, m³)

  • Description (Optional):
    Add any additional notes or explanation about the fuel.

  1. Save

After completing all fields, click Save.
A new emission factor will be created based on the added fuel property and will appear in the results list.

Results Table

At the bottom of the page, the Results Table lists all fuel properties and their linked emission factors.
Each row displays:

  • Emission Source

  • Calorific Value

  • Density

  • Description

  • Action Menu (⋮)

Editing Fuel Properties

  1. Click the “...” (three dots) icon next to the fuel record you wish to edit.

  2. Select Edit.

  3. The form will open with the existing data.

  4. Make the necessary updates and click Save.

  5. The updated information will appear in the table.

Deleting Fuel Properties

  1. Click the “...” (three dots) icon next to the fuel record you wish to delete.

  2. Select Delete.

  3. The system will display a confirmation message:
    “You are about to delete this fuel property record. This action cannot be undone.”

  4. Click Delete to permanently remove the record.

Deleted fuel properties cannot be recovered and must be re-entered if needed.

Using Fuel Properties in Calculations

To use the fuel properties you added in emission calculations,
you must assign them to profiles within the GHG Profile Management section.

After this assignment, fuel properties become active in calculations performed under the selected profiles.
