This is a repository containing a scenario that implements the projections of the van der Meide et al., 2022 study for:
- cobalt.
It is meant to be used in premise
in addition to a global IAM scenario, to provide
refined projections for the future supply of cobalt on the global market.
This data package contains all the files necessary for premise
to implement
this scenario and create market-specific composition for cobalt (including supply from recycling channels).

ecoinvent 3.8 cut-off
The following coupling is done between IAM and the cobalt scenarios:
IAM scenario | EP2050+ scenario |
---|---|
IMAGE SSP2-Base | Business As Usual |
IMAGE SSP2-RCP26 | Sustainable development |
This external scenario update the ecoinvent global market for cobalt, according to the projections described in van der Meide et al., 2022.
Cobalt
The following market is introduced:
market for cobalt (CP2050)
(GLO)
It is supplied by six cobalt production pathways:
- cobalt from cobalt mining
- cobalt as a co-product from copper mining (ore extraction, processing and electrowinning)
- cobalt as a co-product from nickel mining
- cobalt as a co-product from zinc mining
- cobalt recovered from discarded batteries (hydro- and pyro-metallurgical processes)
This market is relinked to activities that consume metallic cobalt throughout the database, if any.
