This page shows how our carbon report will look once knuslabs starts shipping real pieces. Numbers and origins are illustrative targets, not measurements yet.

Carbon report (preview)

Weighing every panel, from the day we ship.

Here is what that will add up to. The numbers, the methodology, the things we won't yet count, and what we are working toward. This page goes live with real data once the first pieces ship.

Drafted 23 May 2026 · Methodology v0.1 (draft)
By the numbers (illustrative)

A typical knuslabs project, weighed end to end.

38 kg CO₂e

Target per project

Cradle to door, illustrative average

−62%

vs conventional carpenter build

Fewer offcuts, no power tools at home, shorter routes

87%

FSC-certified by mass

Target. Remainder reclaimed or recycled-content

Methodology precision

Honest about uncertainty rather than precise to the gram

Where the 38 kg comes from

A per-project breakdown.

Most of the footprint sits in the wood itself: extraction, kilning, ply pressing. Transport is a smaller share than people guess, because the plan is to mill close to the forest and ship by road or short-haul rail.

By material (target sourcing)

Where each kilogram will come from.

Indicative emission factors per kilogram of finished material, the kind of distance we expect from mill to workshop, and the certifications we'll aim to require. Real figures replace the targets the day we start shipping.

What we will count, and what we won't

The honest boundary.

Every carbon number on this page is meant to cover the items in the left column. The right column is what we have not yet figured out how to measure honestly. Better to leave it out than to guess.

WHAT WE WILL COUNT

Inside the boundary

  • Material extraction and primary processing: mill, kiln, ply press
  • Inbound transport from each mill to the workshop
  • Workshop electricity for cutting, sanding, finishing (green tariff)
  • Packaging materials: kraft paper, cardboard, foam-free corner blocks
  • Last-mile shipping to the customer's address
WHAT WE WON'T COUNT

Outside the boundary

  • Your assembly time and the tools you already own
  • Your home's electricity for living with the piece
  • End-of-life: repair, resawing, eventual disposal
  • Office overhead: rent, design hours, AI compute, laptops
Methodology

How we will get to a number.

A short walk through the math we plan to use. Not a peer-reviewed life-cycle assessment, but specific enough that you can argue with it.

What is next

What we are working toward.

Concrete intentions, sized to a typical year of operation once shipping begins. Progress on each gets published on this same page.

Before launch

Lock in 100% recycled-fibre packaging across every SKU on day one.

Year one

Stand up a take-back and resawing program for end-of-life pieces, starting with Amsterdam.

Year one

Consolidate EU inbound loads through two regional drop hubs to cut average inbound shipping emissions by 20%.

Year two

Publish supplier EPDs for every mill we source from and stop substituting Ecoinvent averages.

Year two

Move workshop electricity from a green tariff to a directly-sourced PPA with an Amsterdam-region wind operator.

This page reads very differently once real pieces start shipping. If there is something we should count, frame better, or hold ourselves to, write in.
