Assumptions and defaults25 entries, 4 warnings
Warnings · 4
m1: Elastane (spandex) has no verified carbon content, so fossil CO₂ from its incineration is not counted.
Grid electricity uses location-based national or regional averages. PACT v3 and Catena-X require the market-based residual mix where contractual instruments exist; supply electricity_factor for contracted or residual-mix power.
Biogenic carbon content 0.0% of product mass is below 5 %: PACT allows omitting biogenic uptake; both figures are still reported.
Temporal scores for desnz_2025 use the edition year; their underlying data are older, so those temporal scores may be better than the data deserve.
Assumptions register · 25 entries
Screening mode: this listing gives no primary data, so every input below that is not a stated material or weight is a named screening default. The result is not PACT-conformant (primary data share 0 %).
Product mass 0.3 kg is a category typical value for "accessory", not a measured weight.
Country of manufacture not stated in the listing; India assumed.
m1: Elastane (spandex) is not in the published factor library; screening proxy proxy_elastane (CONTESTED, technological score 4) used.
m1: material share 5 % is estimated from the listing text.
m2: material matched from "polyester" (family, MEDIUM confidence): 'polyester' with no qualifier is treated as virgin polyester.
m2: material share 95 % is estimated from the listing text.
Textile cutting and making loss 15 % of fabric input (PEF-style screening default), sent to landfill.
Packaging not stated; screening default for accessory: Paper bag / wrap 50 g paper, recycled, Shipping box (share) 80 g corrugated board.
Yarn spinning: 0.353 kg fibre × Ring spinning (cotton, ~200 dtex) electricity: 3.4 kWh per kg yarn (van der Velden, Patel & Vogtlander, Int J LCA, 2014).
Weaving: 0.353 kg × Weaving (air-jet) electricity: 3.6 kWh per kg fabric (van der Velden et al., Int J LCA, 2014).
Dyeing & finishing: 0.353 kg × Dyeing & finishing (wet processing) energy: 7 kWh per kg fabric (electricity + thermal) (Quantis, Measuring Fashion, 2018 (dyeing & finishing = 36% of apparel GHG, largest stage)); thermal energy is modelled as grid electricity (no fuel split available).
Cutting, stitching & finishing: Bag / small leather goods assembly energy: 2 kWh per item (Default assumption (cut, stitch, finish)).
Process energy is unmetered screening data (activity uncertainty GSD 1.5–2.0), on the IN grid.
Inbound transport of materials to the factory is left out of the total, because supplier locations are unknown; its likely size is estimated and reported under the cut-off rule below.
Distribution route is a screening default (1,000 km road), carrying product plus packaging.
Cut-off rule: processes are excluded only where no verified data exists, and each exclusion is estimated where possible and reported (ISO 14044 §4.2.3.3.3). Inbound transport is estimated at 0.0221 kg CO₂e.
Secondary (library) factors are scored at least 3 on technology: PACT v3 Table 12 reserves scores 1-2 for primary data.
Carbon content of pet computed from repeat-unit stoichiometry (0.6250 kgC/kg), pure polymer basis (additives, moisture and finishes ignored).
Paper/board carbon: IPCC 2006 Vol.5 Table 2.4 defaults (90 % dry matter, 46 % C of dry, 1 % fossil).
Use-phase scenario: No energy-using use phase for accessory.
End-of-life route shares: MFP screening scenario for India, not PEFCR: textiles and leather goods 80 % landfill / dump, 5 % burning; plastics 60 % / 10 %; paper 40 % / 5 %; metals and glass 50 % landfill; the rest recovered (cut-off). Anchored on CPCB Annual Report on Solid Waste Management 2021-22 (24 % landfilled, 22 % unaccounted).
Incineration: 100 % oxidation of carbon assumed (IPCC 2006 Vol.5 Ch.5 default oxidation factor for MSW incineration). Energy-recovery credits are not applied under cut-off.
Aggregated secondary factors are used as published in their own GWP basis (AR5, unstated); only gas-split fuel factors and direct gas emissions are characterised with AR6. Residual inconsistency is typically a few percent for CO2-dominated factors.
Sources quoted as published figures (not open-licensed datasets): screening_proxy. Replace with licensed or supplier data before external or comparative claims.
SensitivityThe figure with other published choices
Sensitivity analysis (ISO 14067 §6.4.5, §6.6)
The footprint recalculated with each alternative choice: other published factors, the other allocation method, the grid mix instead of a green-power contract, and the use profile at its uncertainty bounds. A large change shows where better data pays off first.

Screening carbon footprint shown on the Made for Planet catalogue so brands and buyers can see where a product's emissions come from. Reasons: No company data is available for this listing; a transparent estimate from the listing and published factors shows the likely size and the main stages. Audience: Brands and buyers (business-to-business). The estimate is also displayed on madeforplanet.com, labelled as a screening estimate; it is not an environmental claim the brand may use in marketing. Public comparative assertion: no.
Functional or declared unit and reference flow

Functional unit: one accessory delivered and used to the end of its life, sold in India; reference flow 0.3 kg of product.

§7.3 b
cradle to grave. Screening: materials, processing energy, packaging, distribution, use and end of life. Capital goods are excluded, as is usual for attributional product footprints. Stages modelled: raw_materials, production, packaging, distribution, end_of_life.

Inbound transport of materials to the factory: 0.022098 kg CO₂e (screening estimate: 0.353 kg of materials × 500 km by average lorry (UK DESNZ GHG conversion factors 2025, Freighting goods + WTT delivery vehicles); supplier locations are not known)
Allocation procedures

Sensitivity and uncertainty
§7.3 k
1 sensitivity case(s); lognormal Monte Carlo on pedigree uncertainty.
Climate change only: other impacts (water, land, toxicity, biodiversity) are not assessed, so a lower footprint does not mean a lower environmental impact overall. Secondary factors limit accuracy as shown by the data-quality scores.
Value choices
§7.3 n
Cut-off for recycling (PACT); economic allocation only above a 5× value ratio; conservative factor where published values disagree (see sensitivity).
Scope changes and exclusions
