Sustainable Product Costing (SPC)

With the SPC function, you can calculate alternatives in terms of your CO2 emissions from energy use in order to evaluate a climate-neutral manufacturing alternative.

 

Emission Types

With the help of emission types, the CO2 equivalent (CO2e value) caused during consumption or generation is taken into account in the calculation of site costs (consumption costs such as energy, footprint, gas and water costs) and, as a result, in the calculation of machine costs (CO2e rate).

Emission types are created in the Data Administration as basis data. -tbe-

Further Information see "Administer Master Data" > "Basic Data" > Create emission type

 

Add Emission Types to a Location

Emission types can be used at locations to consider CO2 emissions in the investment and machine hour rate calculation of the project. Thus you can administer consumption tariffs for each calculation parameter with validities at the location and assign the created emission types.

In the project, the locations subject to emissions can be added via the Project Cockpit where the cost tariffs and emission types can be managed at the calculation parameters.

 

Use Emission Types in the Machine Hour Rate Calculation

Based on the defined emission types, a CO2e rate can be used on standard machines and project-specific machines to determine the amount of greenhouse gases in the machine consumption calculation throughout manufacturing.

The CO2e rate represents the sum of all occurring CO2e values of the calculation parameters. The value of the CO2e rate is managed at the machine and is later included in the machine consumption calculation at the manufacturing process.

You can have the CO2e rate calculated in the Data Administration at the machine properties (and later in the project at the project-specific machine) via the options "calculated" and "manual" to predefine it manually.

 

Determine the CO2e Rate at the Machine

The calculated CO2e rate is the sum of all CO2e consumptions of the machine.

1. The CO2e consumption of the machine is a compound of the individual demand/consumption values of the calculation parameters and the CO2e value maintained at the emission type.

   

   Calculation sample Energy and Water Cost:

   Demand Machine	CO2e Value Location (emission type)	CO2e Consumption Machine
   Energy Demand 52 kW	CO2e on Energy Costs 12 g/kWh	Energy 624 g/kWh
   Water Consumption 6 m³/a	CO2e on Water Costs 4 g/m³	Water 24 g/m³a

2. The CO2e Rate sums up the individual CO2e consumption values to 648 g/h.

 

Include the CO2e Rate at the Manufacturing Process

The calculated or manually entered CO2e rate is multiplied in the project by the machine time at the production process (Advanced, Technology) and results in the CO2e value:

Following the sample calculation:

CO2e Rate at Machine	Machine Time at Process	CO2e
648 g/h	180 s/piece (0.05 h/piece)	32,4 g/h

In the project structure, the resulting CO2 emission value CO2e is shown in the cost information at the manufacturing process. If the process contains several machines, all CO2e values are summed up.
