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
- 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
- Register that the lifetime for part XX-ECO-100 is 100 000 h.
- Click the
Usage tab. On the
Usage Emission tab, enter emission substance ENERGY, media
code Waste and emission amount 0,02 per lifetime.
- On the

Main Exercises
Purpose: The purpose of this lesson is to calculate
emissions for a purchased and a manufactured part and to understand where the
emissions come from. You should also reflect over the distribution of the material declaration qualities in order to evaluate how reliable the calculated result really is.
Windows:
Calculate Eco-footprint - All Parts
Calculate Eco-footprint - Part
Calculate Eco-footprint Impact- All Parts
Create Eco-footprint History
- Open the Calculate Eco-footprint - All Parts dialog box and
calculate emissions for all the parts and revisions on the site. The calculation is
performed as a background job.
- When the background job is ready, open the Part Eco-footprint window and query for the purchased
parts.
- For the purchased parts, right-click in the header and select the option In Progress.
- Analyze the results of your emission calculation. It is important
to understand where the emissions come from.
- Compare the emission of CO2
for the Purchased parts. Which part generates the highest amount of green
house gases? Why?
- Study the EOL Emissions for the different substances
and parts. For part XX-ECO-300 there is a negative value for the substance
PLASTIC. The reason is that the substance is recycled at the end of the
product life.
- Query for part XX-ECO-200 and click the
End of Life
Emissions tab. Change the value of Residue Emission Percentage to 50 since
50% of the substance can be recycled. Recalculate the emissions. What
happened to the EOL Emission for substance CD for part XX-ECO-200?
- If no substances are to be added, removed or modified then update the status to either Complete or Approved for the purchase parts. Which status to select depends on the process and if an Approval is required from some other instance or department.
- Open theCalculate Eco-footprint - Part dialog box and
calculate emissions for the manufactured part XX-ECO-100. Secure that the calculation is performed for Revision No 1 by entering an appropriate Effective Date.
- Right-click in the header and select the option In Progress.
- Open thePart Eco-footprint window and query for your
manufactured parts.
- Analyze the results of your emission calculation. It
is important to understand where the emissions come from.
- Analyze the reliability in the calculated result by studding the circle diagram presenting the percentage distribution between the material declaration qualities in the Material Declaration Quality tab. Also study the declared mass ratio between the built-in substances weight and the part net weight in the Part Eco-footprint header. Can the calculated result be considered as reliable based on the knowledge about included substances? If not what could the explanation be?
- If no substances are to be added, removed or modified then update the status to either Complete or Approved. Which status to select depends on the process and if an Approval is required from some other instance or department.
- Open the Calculate Eco-footprint Impact - All Parts dialog box
and calculate emission impact for all the parts on the site.
- Open thePart Eco-footprint window and query for your parts.
-
Click the
Emission Impact tab to analyze the result of your emission impact
calculation. It is important to understand where the emission impact figures
come from.
- Open the Create Eco-footprint History dialog box and
create emission history data for the site.
