Registered footprint providers

A pathway is a footprint provider's registered calculation method: its database, calculation engine, unit and rating. Each pathway is reviewed and verified separately by an independent auditor. The footprint providers below have registered as applicants; none is certified yet.

Results from different pathways use different methods and are not comparable. They must not be placed side by side or used to compare products.

Eaternity EOS Vita-Score nutrition thresholds
Rating	Threshold

D	≤ 450
E	> 450

Benchmark methodology

CO2 and Water thresholds are derived from the consumption-weighted benchmark using fixed multipliers (A = 0.5×, B = 1.0×, C = 2.0×, D = 4.0×). Vita-Score thresholds are derived from FU-weighted percentiles (A ≈ P10, B ≈ P50, C = P80, D = P90). The DFU is a standardised daily reference unit: DFU = average(protein/50g, fat/66g, energy/6,000kJ, water/2,500g, dry_weight/600g).
