How Fashion Brands Turn Regulation into Competitive Advantage
Fashion brands are now expected to publish product-level environmental scores, often before their data systems are fully ready. In France, this means aligning with the Ecobalyse methodology, while at the EU level similar product transparency requirements are coming through the Digital Product Passport.
For many fashion teams, this requirement arrives before their supply chain data, traceability processes, and LCA workflows are fully in place.
This case study looks at how Kiabi approached that gap. Rather than waiting for perfect data or limiting the effort to a small pilot, Kiabi built an operational system that now supports environmental impact scoring across more than 7,500 products published on Ecobalyse.
The result is not just regulatory alignment, but a structure that can scale, improve over time, and support decisions beyond disclosure.
Why This Case Matters
Many fashion brands face the same practical constraints:
Supply chains spread across multiple tiers and regions
Supplier data that exists, but is uneven or hard to verify
Long onboarding cycles for traceability and digital tools
Difficulty turning traceability data into reliable LCA results
Under regulatory pressure, these issues often lead to rushed disclosures, heavy use of assumptions, or isolated pilots that never scale.
This case study shows what happens when a brand tackles those constraints directly. It documents how Kiabi moved from fragmented data to a working, repeatable system, using real operational inputs rather than one-off calculations.
What you will find in the whitepaper
This whitepaper is not a theoretical overview. It is a concrete account of how environmental impact scoring was deployed in practice, at scale, across a large fashion retailer.
Inside, you will see:
How traceability data feeds directly into LCA calculations and improves score accuracy
How responsibilities were structured between the brand, the traceability platform, and the impact calculation engine
What realistic timelines look like for supplier onboarding and data quality improvement
How data precision can improve progressively, without waiting for complete supplier coverage
How environmental impact data can be used internally for sourcing, eco-design, and decision-making, not just compliance
The focus is on execution: what worked, what took longer than expected, and what other brands should plan for if they want to avoid last-minute compliance.

“When the Digital Product Passport becomes mandatory, it will be a source of pride for us to meet it. We’re preparing for it — and we’re not afraid.”
As the fashion industry enters a transformative era of environmental accountability, the implementation of French Environmental Labelling is not only creating a clear divide between industry leaders and followers, but also reshaping the competitive landscape.
Latest Developments in French Environmental Labelling
The latest developments in this groundbreaking initiative aren’t merely about compliance. Instead, they represent an unprecedented opportunity for companies to demonstrate their commitment to sustainability while simultaneously gaining a competitive edge in an increasingly environmentally conscious market.
Specifically, early adopters of these enhanced environmental impact scoring standards not only meet regulatory requirements, but they also position themselves at the forefront of a global shift toward transparent, sustainable fashion.
Moreover, with consumers increasingly making purchasing decisions based on environmental credentials, mastering these new requirements could be the differentiator that sets your brand or products apart in 2025 and beyond.
This update provides critical information about developments in the Product Environmental Footprint (PEF) methodology as well as the latest changes in regulatory requirements. Notably it clarifies how the PEF methodology forms the basis for the French scoring system used in Affichage Environmental Labelling (Coût Environemental).
Both the PEF methodology and the French scoring system Coût Environnemental rely on the same dataset. However, they apply distinct methodologies to interpret the data and calculate scores. PEF provides a comprehensive lifecycle-based framework for apparel and footwear, utilizing 16 impact indicators in addition to Environmental Footprint (EF) weighting and normalization factors. Furthermore, it leverages a robust database of approximately 5,500 datasets and accounts for functional use (e.g., days of use) to derive its scores.
The 16 impact indicators
Even tough the French scoring system builds on PEF as a foundation yet tailors its methodology to meet local regulatory requirements. For instance, it focuses exclusively on apparel, excludes specific materials such as silk, leather, and cashmere, and uses a much smaller database (~82 datasets).
Additionally, it incorporates other elements not found in PEF, such as emotional durability, microfiber release, and pre-treatment and finishing impacts. Instead of directly accounting for functional use, the French scoring system uses durability multipliers and applies predefined scoring levels. Interestingly, Level-1 scores are always intentionally “reasonably worse” than Level-2.
Essentially, the French scoring system adapts PEF’s framework to fit its specific regulatory and practical needs, creating two different interpretations of the same dataset.
To sum it up, this update provides critical information about developments in Product Environmental Footprint (PEF) and the latest changes in regulatory requirements. For both newcomers and those already engaged with PEF for brands, understanding these updates is essential for successful environmental labelling compliance.
Recent Regulatory Progress
The French government has once again demonstrated its renewed commitment to the French Environmental Score “Cout Environnemental” through recent decisive actions. Notably, on November 28, 2024, the Minister for Ecological Transition, Agnès Pannier-Runacher, launched a public consultation on the implementation decree, marking a crucial milestone in this journey.
Meanwhile, Laurent Bocahut, our CEO at Peftrust, was honoured to attend and support this critical initiative, further emphasizing our company’s dedication to advancing sustainable practices in the fashion industry. The consultation period, which concluded on December 19, 2024, allowed stakeholders across the industry to contribute their insights and concerns.
