Hi team RTLCA
I have noticed that RTLCA re-calculates the total CO2-emissions every time a material is mapped. So the software has two steps at the moment
- Assign the mapped material to the
type - Re-calculated GWPtot
This process takes a while. And if you try to map a new material while RTLCA refreshes, it tends to crash 
The question is, do we need to update the GWPtot calculation every time something is mapped? My suggestion is to remove step (2) and introduce a Refresh calculation button instead. This will save us a lot of hang time and will help us avoid errors
