Required Data

Part Specific Emissions

Purpose: The purpose of this exercise is to enter emissions that are specific for the part. For a manufactured part there could be emissions that are generated during the production process even though it is not included in the routing or in the product structure. These emissions can be registered as Part Specific Emissions.

Windows:
Part Eco-footprint

  1. On the Part Specific Emission tab, enter emission substance PBDE, media code Product and emission amount 0,05 per unit for part XX-ECO-202.

Usage Emissions

Purpose: The purpose of this exercise is to register emissions that are generated when the part is used. You should also enter additional emission, i.e. emissions that are generated for example when the part is repaired.

Windows:
Part Eco-footprint

  1. Register that the lifetime for part XX-ECO-100 is 100 000 h.
  2. Click the Usage tab. On the Usage Emission tab, enter emission substance ENERGY, media code Waste and emission amount 0,02 per lifetime.
  3. On the Additional Emission tab, enter emissions as described in the table below.
Substance No Media Code Emission per Unit Emission Frequency
PB Product 0,01 2
CD Product 0,02 2
CO2 Air 200 2

Calculate Eco-footprint for Purchased Part

  1. Open the Calculate Eco-footprint - All Parts dialog box and calculate emissions for all the parts on the site. The calculation is performed as a background job.
  2. Query for part XX-ECO-200 and click the End of Life Emissions tab. Change the value of Residue Emission Percentage to 50 since that 50% of the substance can be recycled. Recalculate the Emissions.

Calculate Eco-footprint for Manufactured Part

  1. Open theCalculate Eco-footprint - Part dialog box and calculate emissions for the manufactured part XX-ECO-100.

Calculate Eco-footprint Impact

  1. Open the Calculate Eco-footprint Impact - All Parts dialog box and calculate emission impact for all the parts on the site.

Create Eco-footprint History

  1. Open the Create Eco-footprint History dialog box and create emission history data for the site.

Main Exercises

Windows:
Component Eco-footpring Build-Up Graph
Eco-footprints per Part History Graph

  1. Open the Component Eco-footprint Build-Up Graph window and query for your parts.
  2. Study the emission of CO2 for part XX-ECO-100. Which component contributes to the highest emission?
  3. Study the emission of ENERGY for part XX-ECO-100. Select the Use Emissions check box to include the usage phase of the lifecycle in the graph and click Refresh. Which part of the product lifecycle uses the highest amount of ENERGY?

Analyze  Eco-footprints per Part History Graph

  1. Open theEco-footprints per Part History Graph window and query for your parts.
  2. Select a substance and click Show History graph to study the result of previous emission calculations.
