A Free Database Makes It Harder For Brands To Fake Their Carbon Numbers

Carbonfact has opened up over 300 datasets on the carbon cost of making clothes, free for any brand to use.

Fashion sustainability platform Carbonfact has launched an open source database covering environmental impact data for textile manufacturing. The release follows the company's acquisition of Vaayu, a rival platform, and comes as brands race to meet incoming European product-level disclosure rules, according to FashionUnited's report.

The Database in Detail

The release includes over 300 datasets spanning spinning, dyeing and weaving, the production stages that are hardest for most brands to measure accurately on their own.

These stages sit early in a garment's life cycle, often across multiple supplier factories in different countries, which makes them harder to track than final stitching or packaging.

Carbonfact has made the datasets freely downloadable rather than restricting them to paying clients, a departure from how most Life Cycle Assessment (LCA) providers have historically operated.

A Costly Barrier, Now Lowered

Building accurate life cycle assessment data in house is expensive and slow, often requiring specialist consultants and months of supplier audits.

Smaller brands in particular have relied on rough estimates or broad industry averages that may not reflect their own specific supply chain, simply because building anything more precise was out of reach financially.

Where the acquisition fits in

Carbonfact's acquisition of Vaayu consolidates two competing carbon measurement platforms into one, at a moment when EU reporting rules are pushing more brands to disclose this kind of data regardless of company size.

Consolidation in this space has been expected for some time, as smaller measurement providers struggle to keep pace with the volume of regulatory requirements now landing on brands across categories.

What proof means going forward

Free access lowers the barrier for smaller brands to report against a credible baseline rather than an estimate pulled from general industry figures.

That does not make every sustainability claim built on this data automatically true. It does raise the minimum standard of evidence a brand needs before making one, which is a meaningful shift on its own.

Who benefits most

Independent designers and small manufacturers stand to gain the most from this release, since they were previously the least likely to afford commissioned life cycle assessments of their own supply chains.

Larger brands with existing carbon reporting systems may see less immediate benefit, though the open dataset could still serve as a useful cross check against their internal figures.

How the Industry Has Reacted

Early reaction from sustainability consultants has been broadly positive, with several noting that open data reduces the risk of brands selectively cherry picking whichever emissions estimate makes their supply chain look best.

Some industry watchers have raised a separate concern, that open datasets could eventually be used to compare brands unfavourably in public rankings, without accounting for genuine differences in fibre choice or regional manufacturing conditions.

Where the Data Comes From

Carbonfact has said the datasets draw on a combination of supplier reported figures and independent verification, though it has not published the full methodology behind every regional variation included in the release.

Analysts tracking the carbon measurement space expect other providers to respond with their own open access moves in the coming months, rather than cede ground to a single free standard.

A Test Case For Open Data in Fashion

If brands widely adopt Carbonfact's free datasets, it could establish an informal industry benchmark, similar to how certain testing standards became default references in other manufacturing sectors over time.

Whether that benchmark holds will depend on continued funding for Carbonfact to maintain and update the data, since a static dataset would lose relevance as manufacturing practices and regional grids change.

Key Takeaways

1. Carbonfact released a free, open source database of over 300 datasets covering key stages of textile production.
2. The release follows Carbonfact's acquisition of rival platform Vaayu.
3. Free access lowers the barrier for smaller brands to report on their carbon footprint accurately.
4. Buyers should expect more brands to cite carbon data. Ask what the figure is based on, rather than accepting that it exists.
5. Spinning, dyeing and weaving are the stages most brands struggle to track, since they often span multiple supplier factories across countries.
6. Open data gives third parties a public reference point to check a brand's numbers against, rather than taking claims on faith.
