/ffe-carbon-score

Score the embodied carbon of your FF&E spec in seconds.

sustainability carbon specs
Inputs
  • list of products with subcategory and optional weight
  • optional vendor-supplied carbon
Outputs
  • per-line embodied carbon estimate
  • BOM total
  • calculation method per line (categorical-average / vendor-override / weight-based)
Distribution
  • claude-skill
  • google-sheet

The carbon-scoring skill turns an FF&E spec into a footprint estimate. Drop in a list of products; get back per-line and total embodied carbon, plus a clear note on how each number was derived (vendor data, categorical average, weight-based estimate, or “missing — flag”).

Why this exists

Carbon math on FF&E specs is currently either skipped (no time), guessed (no method), or outsourced (slow + expensive). Canoa already has the taxonomy — 36 furniture subcategories mapped to cradle-to-gate kgCO2eq with conservative variants, average mass, and GHG/mass ratios. This skill packages the taxonomy plus the scoring logic so a designer can run it in 15 seconds inside their normal workflow instead of pulling a sustainability consultant into a spec review.

Method

For each line:

  1. If vendor-supplied carbonEmEq exists → use it (vendor-override).
  2. Else if weight + GHG/mass ratio for the subcategory → multiply (weight-based).
  3. Else → use the categorical average for the subcategory (categorical-average).
  4. Else → flag as missing data.

Total is the sum across all lines, with a confidence breakdown by method.

Distribution

  • Claude skill — paste a BOM, get scoring with per-line method notes.
  • Sheet template — taxonomy as a lookup tab, formulas score each row, total in the header.

Status

Alpha — the taxonomy CSV (db/services/elements/bulkupdates/carbon-taxonomy.csv) is the entire knowledge base; the scoring logic is ~50 lines of Python. Self-contained; ships independently of the wider catalog dataset.

Install

/ffe-carbon-score is part of the Canoa agent. Copy the install prompt below and paste it into Claude — it walks you through install, sets up the master schedule Sheet, and brings the rest of the toolkit with it.
