Methodology

How we calculate a product carbon footprint

Honest screening for SMEs: cradle-to-gate, pack-based factors, clear assumptions. Not a certified LCA.

What we measure

GreenCount is for SME product-level carbon assessment and carbon labelling. You describe a product; we match a Knowledge Pack (coffee, tea, spices, cashew today), collect activity facts, and issue a screening carbon label with hotspots, PDF, and an optional public verify page.

System boundary — cradle-to-gate

Default boundary is cradle-to-gate: cultivation → processing and energy → packaging at the facility → inbound transport. Pack copy states the exact gate (for example farm → roast → pack for coffee).

Out of scope: consumer use, retail, and end-of-life (not cradle-to-grave). Downstream logistics only if you enter them.

Emission factors

Factors live in versioned Knowledge Packs (L1 screening defaults with provenance notes). The language model does not invent kg CO₂e. Shared rows include India grid screening (CEA-aligned order of magnitude), freight, and packaging. Crop packs override cultivation and process add-ons.

Measured vs estimated

  • Your facts — volume, process route, energy, packaging — when you provide them.
  • Pack defaults — used when a fact is missing; shown as lower data quality.
  • Optional activities left blank contribute zero (not a hidden average).
  • Confidence notes on the label say what would raise certainty (metered kWh, primary farm data).

GWP and units

Results are reported as kg CO₂e per functional unit (100-year GWP reporting convention). L1 packs are a screening mix: some source rows (notably India grid CEA baselines) are often CO₂-only, not a full Kyoto / IPCC AR6 basket. Do not treat totals as inventory-grade GWP100 until L2 lock.

Assumptions we disclose

  • Organic flag applies an indicative 8% cultivation credit only — not a certification claim.
  • Annual volume normalises a per-unit result from the screening total.
  • Every label carries a screening disclaimer. Sources & method cites curated pack evidence, not live search.

What we are not

  • Not ISO 14067 or a certified LCA
  • Not ecoinvent / Agri-footprint licensed rows
  • Not a government filing or offset product
  • Not generic “AI ESG” scoring for the whole company

Industry coverage

Packs today: coffee, tea, spices, cashew. Other SME categories (including handicrafts) are on the roadmap — we will not invent a pack or a number for them until factors are reviewed.

Common questions

What is a product carbon footprint on GreenCount?
A screening estimate of greenhouse gases associated with making a product, reported as kg CO₂e per functional unit (for example 1 kg green coffee equivalent).
What system boundary do you use?
Simplified cradle-to-gate: cultivation, processing and energy, packaging at the facility, and inbound transport. Not full cradle-to-grave (use and end-of-life are out of scope).
Where do emission factors come from?
Versioned Knowledge Packs. The model never invents kg CO₂e. Live web research is only used for improve context after a result.
Is this a certified LCA or ISO 14067 label?
No. It is a screening assessment for learning, buyer conversations, and improvement priority — not a third-party verified declaration.
