If the new French Textile Environmental Cost law (a.k.a. the France Textile Eco-Score) is to be seen, then yes, anyone can publish the official Environmental Cost scores for your textiles if you don't yourself disclose them by the end of the voluntary phase.

Control your brand's sustainability narrative, before someone else does it for you

The new Textile Environmental Cost, (coût environnemental) enters into force in as of today - the start of October 2025. The portal to report the different metrics for textile manufacturers has been open since mid-September. The enforcement initially begins with a voluntary phase from 1st October 2025. Anyone can publish a score on your behalf if you have not published a score by the end of the voluntary phase. No permission needed, and this will be an official score displayed on all your garment tags, website, and product pages.

What is the France Textile Environmental Cost?

The new decree requires all companies who sell garments in the French market, not just French companies, to publish an "Environmental Cost" score for each of their products. This is an aggregate score that considers all factors related to the environmental impact of a garment. This includes carbon emissions, energy use, microplastic impact, durability, and more. All companies are encouraged to publish a score in the voluntary phase beginning in October 2025. Once the voluntary phase ends, ANYONE can publish a score on behalf of the companies if they continue to sell in the French market.

How NGOs and other third-parties could publish a potentially worse score for you

What does this mean? NGOs who might use assumptions for your supply chain will control your narrative. They might publish a score which might denote a far higher environmental impact than actually the case. From an NGOs perspective trying to champion the cause of the environment, they will use negative estimates where subjectivity is permitted. For example, standard (or even unsustainably sourced) cotton, zero recycled fabrics, high transport emissions, and poor durability. While you may think your brand's organic cotton tee shirt may land a low environmental cost score of 500 (lower score is better), the NGOs assumption may lead to a score calculation of 1000+. Our team analysis has observed this in the official Environmental Cost portal.

It is also worthwhile to note that the Environmental Cost score will be visible everywhere. In physical stores on product tags, online in the product description, and with QR codes that redirect consumers to a landing page with the breakdown of the score. It is the first instance where factors like durability are also included. These have until now have not had much negative impact on fast fashion companies. If you're a textile brand selling apparel in the French market and you haven't submitted data to calculate your score, any third-party can publish a score for you once the voluntary phase ends. This will be mandated to be included on your own product pages, tags, and more.

An example of how an NGOs score created for you could be worse

Suppose your company manufactures a tee shirt. It uses 150g cotton, with 80% organic cotton and 20% sourced from production waste. You've set up your supply chain in an Eastern European country from the spinning to weaving to stitching. You use custom steps in the process to reduce the environmental impact and minimise your fabric wastage in production. By entering data in the Environmental Cost portal, you have achieved a low score of 500+ for your tee shirt.

The same score calculated by a third-party like an NGO may not be the same. How? Well for example, the NGO will assume your cotton to be standard cotton - not recycled or organic. Then, it will take a look at your product tag which says "Made in the Czech Republic". They naturally assume that it is for the final step, not the spinning of the yarn all the way to weaving the fabric. They assume that these initial steps are done in Asia-Pacific and accordingly take the average values. It will also consider industry default processes, industry averages of the manufacturing steps and assume a standard fabric wastage value. The result? Your low impact tee shirt in reality gets a high score of 1279. Good luck convincing your customers to buy your "organic" tee shirts now.

How much worse can your score get when rated by a third-party?

The short answer is very much worse. As seen in the example above, assumptions made by a third-party even with the best of intentions will lead to a significantly worse Textile Environmental Cost for your garments. There needs to be no malicious intent for general assumptions like standard cotton, industry average processes, and sourcing the yarns to spin your fabric from major global hubs. Yet, these can lead to a worse Textile Environmental Cost for your products, as calculated on the official portal.

How do you control your Textile Environmental Cost then?

So how do you control your narrative? How do you communicate your true environmental cost to your customers? Not an exaggeration by a third-party which has no stake in your business? One option is getting started with the portal yourself or through your company's legal team. However, keep in mind that the Environmental Cost requires 10+ variables per garment type you sell. Multiple that with 100s of types and styles you might sell, and the input cost of gathering this data potentially exceeds your total revenue from selling in the French market.
