I can’t help, but thank you for putting me on to no thanks

Its a great idea. I think it would be challenging to implement and would need quite a lot of domain expertise to really unpick. Need to have enough teeth to be able to assess whether level of action and emission mitigation is: above and beyond; in line with paris agreement needs; below needed but active work due to constraints; actively harmful company . E.g. some companies might be intrinsically high emitting because of their sector (e.g. steel manufacture) but doing all they can to decarbonise whilst some might instead be "decarbonising" largely through accounting tricks like offsets and others still just bankrolling delay and denial. Assessing what a Paris Agreement compliant pathways for sub- and multi-national organisations is actually really tricky. Similarly tricky to assess what "as fast as possible" really is for the same organisations.

For finance sector I know this: https://bank.green which might help some.
