Every LCA has a dirty secret: the inventory. Reeco is verified.
A PEF calculation has two layers.
1. The Life Cycle Inventory (how much material actually flowed through each stage, per unit)
2. The impact factors applied to it.
The industry obsesses over the second layer and hand-waves the first. Industry-average inventories, documentary weights, supplier estimates.
Then a precise-looking number comes out, built on inputs nobody checked.

Reeco inverts this.

The inventory feeding our PEF is the same per-unit mass balance ledger that governs DPP issuance (see methodology published on Zenodo and deposited).

Certified volume in, from Transaction Certificates verified.
Consumption out, derived from our metodolody parameters.
Explicit tolerance: Δ ≤ 0.05%.
Four tiers out of four, fiber to garment.

When the reconciliation closes, every gram in the inventory is accounted for. When it does not close, the system says so before issuance, on the record.

This is the equation: mass balance verification = inventory verification.

A PEF computed on a reconciled ledger is not an estimate wearing a lab coat. It is a calculation on verified physical flows : "the same flows a market surveillance authority can audit through the signed credential trail".

Full disclosure, in the credential itself: activity data verified per unit; impact characterization from the Commission's EF 3.1 reference database, per PEFCR Apparel & Footwear v2.0, 16 impact categories.

We verify what can be verified and declare what we apply.
Vendors presenting industry averages as product-specific footprints disclose neither.
The inventory either reconciles or it does not.
Ours does — and you can check, welcome to contact us for a clear testing of your production flows and full PEF auditing.
