Methodology

To provide accurate and up-to-date information on the environmental impact of your products we rely on the European PEF method and the best available data, ensuring that we are always ahead of demand and that you can stay ahead of the game.

PEFtrust®, PEF Compliant Platform

PEFtrust® is a SaaS platform developed by L’Empreinte for Apparel, Footwear and Fashion Accessories brands.

Our mission is to give fashion manufacturers the keys to consistently measure and comparethe footprint of their products.

In order to provide them with an objective and quality analysis of their product’s life cycle,we use the only method recognized and recommended by the European Commission :

  • The PEF (Product Environmental Footprint) :
    our PEF methodological reference frameworks are the PEFCR T-shirt and the PEFCR Apparel&Footwear.

It is a precise and comprehensive method that allows us to processdata related to the activity and the environment at product level. This results in a single PEF score which measures the global environmental cost of any consumer product :

 

Activity data
(with brands and distributors)
xEnvironmental data
(EF, Ecoinvent…)
=PEF SCORE

 

  • The lower the PEF score, the lower the environmental impact of the product.

Comprehensive Product LCA

LCA implies a better traceability of products and data as well as an increased exchange of information with suppliers.  

That’s why, PEF, the EU-standardized method makes it possible to evaluate the life cycle of each product in its entirety : from the extraction of raw materials to its end of life thanks to the “cradle to grave” method :

This includes the production of fabrics, assembly, storage in warehouses, sale online or in shops and use (washing machine, dryer, ironing, etc.).  

Please note that this should not be confused with the “cradle-to-gate” method,which does not provide a EU-compliant environmental score because this analysis stops at the factory gate and does not take into account distribution, use and end of life.

Accurate Environmental Assessment

The assessment of an environmental impact is quantified through the measurement of environmental impact indicators. The PEF monitors 16 impacts divided into 3 categories.

Human Health

  • Climate change
  • Ozone Deletion
  • Ionizing radiation
  • Ozone formation
  • Fine particles
  • Non-Cancer Human toxicity
  • Human Toxicity Cancer

Natural Ressources

  • Land Use
  • Miniral Depletion
  • Ressource Depletion, Fossil Fuel
  • Freshwater Scarcity

Ecosystems

  • Acifification
  • Terrestrial Eutrophication
  • Freshwater Toxicity
  • Marine Eutrophication
  • Eutrophication Freshwater

16 Impacts = 1 score

Effective Way To Compare Products

The PEF method provides a reliable, objective and reproducible score.  

This score allows :  

  • Consumers to compare the environmental footprint of products from the same category (example: two cotton T-shirts) or from different categories. 
  • Brands to benchmark, understand and improve their products collection after collection thanks to eco-design. 

Quick Results

With few data, you can already enter the era of environmental calculation and implement the first actions.  

As time goes by, a better completeness of your data will allow you, step by step, to refine your results, to comply with current regulations and to communicate them more widely.  

To guide you, PEFtrust® offers you a “3-levels quality ratio”

The Only Method Recognized By The European Commission

The PEF is a scientific and serious method on which more than 3000 European actors are working since 2013. Scientists, NGOs and industrialists have joined forces to create a state of the art method recognized worldwide 

  1. Grenelle of the environment1 & 2 :
    Raising consumer awareness of the environmental impacts of consumer products

  2. National experimentation CGDD
    (General Commission for Sustainable Development)

  3. Single Market for Green Products Initiative
    Launch of the PEF (Product Environmental Footprint)

  4. Energy transition law
    Obliges manufacturers and distributors to make available to consumers the technical data used to communicate the environmental performance of their products

  5. PEFCR Footwear
    PEFCR Tshirt
    PEFCR Leather
    OEFCR Retail

  6. FREC (Circular Economy Roadmap)
    Encourage eco-design, deploy voluntary environmental labelling of products and services in the five pilot sectors (furniture, textiles, hotels, electronic products and food products) and extend it to other sectors

  7. AGEC Law (Anti-waste law) – article 15
    – Environmental labeling system
    – 18-month environmental experiment to evaluate different methodologies and labeling methodologies
    – Environmental labeling scheme made compulsory for the textile sector as a priority

  8. PEFCR Apparel Footwear
    – Loi Climat et Résilience – Article 12
    – Environmental labeling intended to provide consumers with information on environmental impacts and compliance with social criteria
    – The textile sector has been identified as a priority for the implementation of an environmental labelling scheme
    – Impacts to be taken into account: greenhouse emissions, damage to biodiversity, water consumption and natural resources
    – First environmental labelling for textile and food products in 2023
