/ffe-carbon-score
Score the embodied carbon of your FF&E spec in seconds.
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:
- If vendor-supplied
carbonEmEqexists → use it (vendor-override). - Else if weight + GHG/mass ratio for the subcategory → multiply (
weight-based). - Else → use the categorical average for the subcategory (
categorical-average). - 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.
