| Goal: application, reasons, audience, comparative assertion §6.3.1 / 14044 4.2.2 | 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 §7.3 a | Declared unit: 1 kg (partial carbon footprint); reference flow 1 kg of product. |
| System boundary §7.3 b | cradle to gate. Screening partial carbon footprint, cradle to gate, per kg: materials and packaging where known. Distribution, use and end of life are outside the boundary. Capital goods are excluded, as is usual for attributional product footprints. Stages modelled: raw_materials. |
| Significant unit processes §7.3 c | glass_container (virgin) (100 %) |
| Data sources §7.3 d | UK DESNZ Greenhouse gas reporting: conversion factors 2025 2025 (flat file) |
| Greenhouse gases considered §7.3 e | CO₂, CH₄ (fossil and biogenic), N₂O and refrigerant gases (HFCs, SF₆, NF₃) where present; secondary factors cover the gases their publishers include. |
| Characterisation factors §7.3 f | IPCC AR6 GWP100 with climate-carbon feedbacks; secondary factors in their published basis where no AR6 version exists (see gwp check). |
| Cut-off criteria and exclusions §7.3 g, o | Inbound transport of materials to the factory: 0.06261 kg CO₂e (screening estimate: 1.000 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 §7.3 h | No multi-output processes. Recycling: cut-off. |
| Timing of emissions §7.3 i, 6.4.8 | All emissions and removals counted as at the start of the assessment period; no delayed-emission weighting. |
| Data description and quality §7.3 j | PACT Table 12 DQR: technological 3, geographical 5, temporal 1; per-line scores, confidence and 95 % uncertainty in the inventory. |
| Sensitivity and uncertainty §7.3 k | 0 sensitivity case(s); lognormal Monte Carlo on pedigree uncertainty. |
| 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. |
| Life-cycle stages, use and end-of-life scenarios §7.3 p, 6.3.7, 6.3.8 | Not in scope (partial carbon footprint, cradle-to-gate). |
| Influence of alternative scenarios §7.3 q | No alternatives available for the choices made. |
| Period the footprint represents §7.3 r, 6.3.6 | 2026-01-01 to 2026-12-31: current production as represented by the factor library (each factor's own data year is scored in the temporal data quality) |
| Product category rules §7.3 s, 6.2 | No product category rules conforming to ISO/TS 14027 are known for this product category; MFP screening rules are applied and disclosed. |
| Performance tracking §7.3 t, 6.4.7 | Not a performance-tracking study. |
