What impact assessment method?

[bl-young]

I would think the elci should be agnostic to LCIA method? My guess is that for the one on the LCA Commons currently, the impact assessment methods were added after the eLCI data were in openLCA. I think in most cases moving forward we would not want the repositories on the commons to contain impact methods.

Relatedly, the old "NETL_mod" was to enable the use of AR5-100 yr instead of TRACI's AR4-100 year. We now have explicit IPCC methods available through the LCIA formatter (AR4 through AR6)

If for some reason you did want to add an impact method to the jsonld file in elci, I woudl think you could simplify it greatly through something like:

import lciafmt
df = lciafmt.get_mapped_method(method_id='TRACI2.1',
                               download_from_remote=True)
lciafmt.to_jsonld(df, zip_file = 'my.zip')

using get_mapped_method() with download_from_remote=True will use already processed versions from data commons that have been validated

Seems reasonable, Ben. Unless I hear otherwise, I'll refrain from including the impact methods from the inventory. One less thing to have to worry about.

Agreed on not including an LCIA method in the elci json-ld output. It also appears to be inconsistent with respect to the commons - USLCI for example does not include any LCIA methods.
