Regioinvent v1.2.1

Added more commodities to the list of regionalized products.

Regioinvent v1.2

• Now works with ecoinvent3.9.1 AND ecoinvent3.10
• Uses BACI database instead of UN COMTRADE now. BACI is still based on COMTRADE but corrects inconsistencies in the data which we do not have to do anymore.
• Mapping between ecoinvent and HS codes redone. The previous mapping based on what ecoinvent directly provided had a lot of mistakes in it.
• Switched from IW+ v2.0.1 to IW+ v2.1. So there is a new regionalized impact category now: Particulate matter formation. + all the corrections brought in the v2.1 of IW+ which you can see here: https://doi.org/10.5281/zenodo.14041258
• Refactoring of the code for spatialization which will make it easier in the future to add other LCIA methods than IW+
• Recalculation of the production volume estimates with EXIOBASE. Previously the Z matrix was used, instead of using the x matrix to also include final demand in the ratio.
• Added detailed methodology description

Regioinvent v1.1.4

Just changed the name of "global production markets" to global export markets" as the data used only covers export data and not domestic production data.

Regioinvent v1.1.3

Corrected mistake in regionalization of irrigation technosphere inputs for commodities using the technosphere inputs "market group for irrigation".

Changed terminology from biosphere_regionalized to biosphere_spatialized.

Regioinvent 1.1.2

Corrected problem where RoW geography was missing in impact categories such as land and acidification/eutrophication. It resulted in a null characterization factor instead of a global factor.

Regioinvent v1.1.1

Correction of mistakes in mapping of land regionalized flows with their characterization factors.

Regioinvent v1.1

New

Water processes were created to fix the water unbalance created from regionalizing and from the base ecoinvent database. The issue at hand was that, e.g., the production of apple in Chile was using an RoW irrigation, and so was using "RoW" water and not Chilian water, hence the unbalance.

In addition, these created water processes were regionalized (electricity, heat and waste inputs)

Finally, the data from the UN COMTRADE was refined to correct blatant mistakes and unit issues. The format of the file changed and the code was adapted to it.

v1.0.1

New

Ecoinvent processes are now relinked to created regioinvent processes.
For instance, the production of electricity from hard coal in Canada now uses the consumption market of hard coal in Canada as an input.

v1.0

Supported features:

• Regionalization of key inputs: electricity, solid waste management, heat
• Regionalization of elementary flows pertaining to the following broad impact categories: water use, land use, acidification/eutrophication
• Automatically creates a regionalized biosphere3 version, an only-elementary-flow-regionalized version of ecoinvent and automatically imports the regionalized version of the IMPACT World+ LCIA methodology
• Domestic consumption estimated through EXIOBASE
• Cut-off for importing/exporting countries represented in the final regioinvent database set to 95% (99% makes AB bug)

Non-implemented features:

• Regionalization of non-traded goods (e.g., a building) and of services (e.g., baling or hot rolling of steel)
• Tailored transportation for production/consumption markets (taking the original distribution of ecoinvent)
• Specific shares for import/export per technology of production (taking the original distribution of ecoinvent)
