Target setting method regarding ETF!

I have question regarding “Exchange Traded funds”. It says setting target for ETF is mandatory, but using PCAF methodology we were not able to calculate its emission due to lack of information about underlying assets. So the question is, if we are not able to calculate carbon emission for the following asset class(ETF), can we eliminate that asset class when setting the target? If it is mandatory, is there anything we can do without knowing the emission?

Plus, I think there’s something wrong with the tool…
it gives out higher intensity goal for the target year…
Please let me know about that (also, 2021 is still not avaliable)
