...what's the exact cell where the error occurs?

this one here: lca.lcia() But I guess the LCIA Method is not declared correctly: CC_method = [m for m in bd.methods if 'IPCC 2013' in str(m) and 'climate change' in str(m) and 'GWP 100a' in str(m) and not 'no LT' in str(m)][0] CC_method

I tested a little yesterday, but was unable to fix the notebook yet. Please use one of the other notebooks from our teaching repository for the time being: https://github.com/brightway-lca/from-the-ground-up
