Some of the impact categories give 0 results

Question

Hi,

After running the calculation, I found that 1 of the impact categories give the 0 results, which is for ecosystem quality - ionising radiation. Is it normal? if not could you suggest anything to fix it?

Thanks

Answer 1

Hi, this happens if either:
- your product system does not have emissions or resource use for the specific category; maybe also because your system omits important supply chains for example, in this case you will typically see products in the input side of the calculation
- the emissions or resource use are not recognised by your categories
Best wishes,
