Adding Carbon Content

The Carbon Content task enables you to configure the carbon dioxide (CO₂) emission factor. One of the primary determinants of carbon dioxide (CO₂) emission is the amount of carbon in the fuel. Carbon content varies, so typically average carbon content values are used to estimate CO₂ emissions. You obtain carbon content data for specific fuels from the carbon content protocol you are using. Archibus uses the carbon content values you enter to determine a carbon content emission factor using the following calculation:

CO₂ Emission Factor = Carbon Content x Oxidation Factor x 3.67.

where 3.67 is a constant conversion factor used to convert carbon to CO₂.

For more information, see Calculating Emissions for Stationary Fuel Combustion.

By default, carbon content is measured as kg C/GJ (kilograms of carbon per gigajoule of fuel), but you can define different units if needed.

To add carbon contents version and data:

1. Select Carbon Footprint - Background Data / Carbon Content.
2. To add a carbon contents protocol version:
   1. Click Add New > Carbon Content Version.
   2. Enter the following information:

      Version: Enter the protocol version you are using for carbon content data.

      Version Description: Enter a description, such as the table number the data is found in, or the year the data is for.

   3. Click Save.
3. To add carbon contents data:
