The `resourceUse` indicators of each Ecoalim process mapped to a HESTIA Input term: one row per process, one column per HESTIA term.

Every value is per one reference unit of the process — typically 1 kg, 1 MJ or 1 m³ — calculated in openLCA with EF 3.1 Method (adapted), economic allocation and regionalisation, and converted to HESTIA terms with [hestia-convert-base](https://gitlab.com/hestia-earth/hestia-convert-base) and the [hestia-flowmaps](https://gitlab.com/hestia-earth/hestia-flowmaps). A flow with no mapping contributes nothing.

## Changes from the source

The inventory is grouped into few columns on purpose: each column becomes one Emission or resourceUse indicator per mapped Input on every Cycle that uses this lookup. How each group is formed is in `ecoalimV9.md`, linked below.

- Values rounded to 3 significant figures; nothing is dropped for being small.
- Regionalisation summed away: a cell is the total over every location.
- The columns are the same in every dataset. A column this dataset has no value for holds `0`, which means none reported, not impossible.
- 51 fixed columns, not filtered by EF score: freshwater withdrawals, freshwater consumption (not for worldSteel), energy depletion split into fossil and the five non-fossil Cumulative Energy Demand categories, minerals and metals in kg Sb eq, 6 land occupation columns and 36 land transformation columns, one for every ordered pair of the landCover parents `annualCropland`, `permanentCropland`, `permanentPasture`, `otherLand`, `forest`, `waterBody`, into which every land use flow is aggregated.
- `freshwaterWithdrawalsInputsProduction` is the water taken in: "Emissions to water" are not subtracted, and "Water, turbine use" is ignored. `freshwaterConsumptionInputsProduction` is taken in minus returned, from the impact method's own non-regionalised water use ÷ 42.95, in L.
- A fossil or mineral flow with no direct flowmap to a depletion indicator is converted by the CML2001 "during Cycle" models, with densities and energy contents that can differ from ecoinvent's.

How each choice was made and measured, and this dataset's known limits, are in `ecoalimV9.md` in the newest [release folder](https://gitlab.com/hestia-earth/hestia-glossary/-/tree/develop/background-emissions/releases). `ecoalimV9-resourceUse-changelog.md` says which values each release moved.
