Eaternity EOS — Provider Pathway under EmpCo
Governance note. The normative-floor items (LCIA method, functional unit, rating system) are draft framework-level requirements subject to ESFC EmpCo Working Group consultation. Changes follow GOV-02 stakeholder consultation.

Functional-Unit Revision: the VpF Daily Food Unit
The functional unit is a normative-floor item, so the framework-level change remains subject to ESFC EmpCo Working Group consultation. As of the 2026-08 update, this portal's rating benchmarks and thresholds are stated on the VpF unit; the engine-side rollout follows, and ratings compared against those thresholds must use VpF-computed DFU values — per-DFU figures from the previous unit are not comparable.
What changes. The revised unit (VpF, from the lci-dfu publication line) derives every denominator from one reference person — the WHO/FAO 60 kg adult at 2,000 kcal/day — instead of mixed bases:
DFU = (protein/50 + fat/66 + restkJ/5076 + water/2500 + DW/325) / 5, DW = mass − water − protein − fat
- Rest-energy denominator 6,000 → 5,076 kJ. 2,000 kcal × 4.184 − 17×50 − 37×66. The former ~2,200 kcal basis forced carbohydrate above EFSA's 60 E% ceiling (61.6 E%); at 2,000 kcal the macronutrient split (10 / 29.7 / 57.8 E%) sits inside the EFSA reference ranges.
- Dry weight becomes macro-stripped (mass − water − protein − fat), symmetric with the rest-energy term, which strips the same two macronutrients — protein and fat are counted exactly once. The 325 g denominator is the same reference person's macro-stripped dry matter (carbohydrate 289 + fibre 25 + ash 11 g), replacing the previously unsourced 600 g; four independent reconstructions of daily dry-matter intake converge nearby (EFSA-DRV 490, WHO/FAO-global 438, menuCH 435/463 g).
- What it does not claim. No DFU variant prevents dilution — adding water always lowers impact per DFU through the water term, a property the publication states openly. The dry-weight term provides dry-matter discrimination at fixed mass, not an anti-dilution mechanism. A fully-stripped variant (VpFC) was evaluated and rejected: its residue goes negative for ~2% of real food-composition rows.
Measured effect on the 108-kitchen benchmark (three years, identical CO₂, both units run on the same rows): total DFU +3.7%, so carbon per DFU shifts 3.412 → 3.289 kg CO₂e/DFU (×0.964). The shift decomposes exactly — +138,660 DFU from the rest-energy denominator, +81,140 from the dry-weight change — and is a unit change, not a change in measured consumption or impact. Zero negative dry weights occurred under macro-stripping across 1.7 million delivery rows. If adopted, DFU-denominated rating thresholds shift by the same mechanical factor.
