Hello,
I have a data model, which might have some issues.
The Case:
A category can have several models, which come with different properties such as the release date.
A model can have several materials in gram, and a material can be used by several models.
A model has exactly four life cycle stages in which it causes emissions, in the unit kgCO2e.
This results in the following field view (unnecessary tables and columns such as the Ids are hidden):
What I try here is to analyze the Greenhouse Gas Emissions and amounts of materials used by Apple products.
This works well when I only use the grams for the materials and the kgCO2e for the emissions.
So it is possible to show in a matrix table, which category emits how much greenhouse gas in which life cycle stage:
But how can I get percent values in such a table?
For example: The MacBook should have 21,29% ((2.967,20 * 100) / 13.940,00) at the stage of customer use.
This would also be helpful when I try to visualize the percentage developments of the emissions.
I would be very thankful for any help with this problem!
Thanks and Regards,
Chris
