Assumptions and defaults14 entries, 1 warnings
Warnings · 1
Excluded processes = 11.86% of cradle-to-gate emissions, at or above PACT v3's 3 % cap. The PCF is NOT PACT-conformant until these are modelled.
Assumptions register · 14 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 %).
The listing states no weight and no typical weight is on file for "home and kitchen item", so the footprint is given per kilogram of product (ISO 14067 declared unit). Enter the product's weight for a per-item figure.
Country of manufacture not stated in the listing; India assumed.
m1: material matched from "wood" (family, MEDIUM confidence): wood of unstated species is modelled as tropical sawn hardwood.
m1: material share 100 % is estimated from the listing text.
Packaging is not stated and no verified default exists for home and kitchen item, so it is excluded.
Making the product: cutting, turning and finishing the wood are not included (no verified figure).
Landfill of wood and bamboo is modelled with the library's paper landfill factor, the closest available; no wood landfill factor is on file.
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 0.0626 kg CO₂e.
Wood carbon: IPCC 2006 Vol.5 Table 2.4 defaults for wood products (85 % dry matter, 50 % C of dry, no fossil carbon); carbon in panel adhesives is not separated.
Aggregated secondary factors are used as published in their own GWP basis (AR5); 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): epdhub_globaltimber_2023. 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.

Allocation procedures

No multi-output processes. Recycling: cut-off.

Sensitivity and uncertainty
§7.3 k

Electricity treatment
§7.3 l
No electricity in scope.
Interpretation, limitations
§7.3 m, Annex A
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
§7.3 o
No product weight is stated, so the study is a partial carbon footprint per kg of product (cradle to gate): distribution, use and end of life are not quantified (ISO 14067 §6.3.3). Packaging is not stated and no verified default exists for this kind of product, so it is excluded without an estimate.

No product category rules conforming to ISO/TS 14027 are known for this product category; MFP screening rules are applied and disclosed.

§7.3 t, 6.4.7
Not a performance-tracking study.
ISO 14067 counts biogenic removals (−1) and emissions (+1) in the carbon footprint; the PACT headline excludes biogenic uptake. Both are shown.
