Product update · July 2026

Better data for textiles.
Now in Green Story.

Green Story now runs on Ecoinvent 3.11— the newest version of the environmental data behind every footprint. For cotton, polyester, dyeing and recycling, it's a big step up from the older data much of the industry still uses.

What it means for your products

Sharper numbers for the fabrics you use

The biggest improvements land exactly where fashion footprints are hardest to get right.

Cotton & plant-based fabrics

The data now follows the carbon a plant takes in as it grows and gives back later. That makes footprints for cotton, viscose and other plant-based fabrics more true to life.

Polyester & nylon

The oil-based data behind synthetic fibres was rebuilt from the ground up — including greenhouse gases from oil and gas that older data simply missed. Polyester numbers are more honest.

Dyeing & finishing

New data for cleaning the wastewater from dyeing and finishing — the most water- and chemical-heavy steps in making fabric — so the messiest part of your supply chain is counted properly.

Recycling & end-of-life

New data for recycling polyester and other plastics — including material recovered from old textiles — so recycled-content and take-back claims stand on real numbers.

3.8 vs 3.11

The jump you're making

Green Story moved straight from Ecoinvent 3.8 — where much of the industry still is — to 3.11. Here's what changes for textiles, side by side.

Before

Ecoinvent 3.8

Released 2021 · where much of the industry still is

Now in Green Story

Ecoinvent 3.11

Released 2024 · the newest data

Cotton & plant-based fabrics
The carbon a plant takes in as it grows wasn't counted separately.
Now tracked properly, so cotton and viscose footprints ring truer.
Polyester & nylon
Older oil & gas data, with some greenhouse gases from extraction left out.
Oil-based data rebuilt across the world, including gases that were missed before.
Dyeing & finishing
Limited detail on treating factory wastewater.
Dedicated data for the most water- and chemical-heavy steps in making fabric.
Recycling & end-of-life
Little data to model recycled content or take-back.
New data for recycling polyester and plastics, including material from old textiles.
Electricity behind the factory
Grid emission factors from years earlier, across the markets you produce in.
The latest electricity grid emission factors — spinning, weaving and dyeing reflect today's grids.

Good to know

What you gain — and what stays

Moving to 3.11 adds the newest data without touching the models you already depend on.

Latest electricity grid emission factors

3.11 brings the most recent grid emission factors for the markets you produce in — so the energy behind every spinning, weaving and dyeing step is measured against today's grids, not a snapshot from years ago.

Your Green Story textile datasets stay

Every proprietary Green Story textile dataset you already rely on is fully included with this change. You gain the newest background data without losing any of the models built for your materials and supply chain.

In Green Story

Switch versions. Keep your history.

A data update used to force a hard choice: stay on old numbers, or lose the ability to compare with everything you've already published. Not anymore.

Fresher data, sharper footprints

Electricity, chemicals and transport sit behind every apparel footprint. Newer data means your numbers reflect today's supply chain, not a snapshot from years ago.

Switch versions, don't get locked in

Pick the data version for each project. Reports and product passports you've already published stay exactly as they were — while new work runs on 3.11.

Answers you can defend

Run a product on two versions side by side and see what moved. When a retailer or auditor asks which data sits behind a claim, the answer is one click.
