About 4_PE_ProcessExtensions_Materials

Hi @stefanpauliuk,

What is exactly included in the GWP of the materials from 4_PE_ProcessExtensions_Materials? For example, is the transport included for aggregates or is it just its production?

Bonsoir @LolaRousseau,
please check pages 102+103 in
https://doi.org/10.6094/UNIFR/242061

GWP of the materials from 4_PE_ProcessExtensions_Materials is based on ecoinvent, so some transport is included there indeed.

But it is not used directy in the scenarios. Instead, we have our own material production inventories (energy demand and production technology mix), which is why we can have H2-based steel in varying degrees.

We take the difference residual = ecoinven - own inventory as approximation for the process emissions and the emissions related to the productoin assets and other ancillary inputs.

Great thank you! I found the materials workbook file that was refered in the parameter file with the list of ecoinvent processes which were used :)
