Méthode d'impact

Why do we display the carbon footprint of our products?

Producing a pair of shoes requires raw materials, energy, and transportation. These activities generate greenhouse gas emissions that contribute to climate change.

To better understand this impact and integrate it into our design decisions in order to reduce it, we developed an eco-design tool in collaboration with SAMI, a specialist in measuring the carbon footprint of organizations and products.

Using this tool, we estimate the carbon footprint of each of our shoe models. The impact is expressed in kilograms of CO₂ equivalent (kg CO₂e) per pair of shoes.

This indicator allows us to:

• improve transparency regarding the carbon impact of our products;

• identify the main sources of emissions;

• integrate eco-design principles into the development of our collections.

How do we estimate the carbon footprint?

The carbon footprint of each model is estimated using our eco-design tool, which performs simplified life cycle assessments (LCA). This method evaluates the greenhouse gas emissions generated throughout a product’s life cycle.

The calculation relies on two complementary types of data.

1. Product-specific data

Each product reference is modeled component by component (upper, lining, laces, soles, etc.). For each element, we specify the material used as well as the corresponding quantity of material.

2. Reference environmental data

The emissions associated with materials and manufacturing processes are estimated using:

• the IMPACTS® Base version 2.01 from ADEME;

• material life cycle assessments conducted by FAIRLY MADE® (2023–2024);

• certain environmental data provided by our suppliers.

Life cycle stages considered

The displayed carbon footprint corresponds to an estimate covering the main stages of the product’s life cycle.

1. Raw material production

Manufacturing of the materials used in the shoe (textiles, polymers, rubber, etc.).

2. Component manufacturing

Transformation of materials into the various parts that make up the shoe.

3. Upstream transport

Transport of materials and components to manufacturing sites.

4. Assembly

Final assembly of the shoe in the production workshop.

5. Distribution

Transport of finished products to warehouses and distribution markets.

6. Use phase

Estimated impact linked to the use of the product during its lifetime.

7. End of life

Treatment of the product at the end of its life (recycling, incineration, or landfill).

Understanding the displayed result

Emissions generated across all life cycle stages are added together to obtain a global estimate expressed in kg of CO₂ equivalent per pair of shoes.

The tool also allows us to identify the contribution of different parts of the product, for example:

• the upper

• the sole

• the linings

• the laces

• assembly

• transport

• use

• packaging

• end of life

This analysis helps us identify the main emission sources and guide our design choices.

Limitations of the estimate

The displayed carbon footprint corresponds to an estimate based on the data available at the time of calculation.

Some data may be:

• specific to our suppliers;

• or based on sector-average data used in life cycle assessments.

The results should therefore be interpreted as orders of magnitude that help identify the main environmental impact sources. The estimates may evolve over time as data and calculation methods improve.

In addition, to compare the environmental impact of different materials, it is necessary to use a common reference basis. In 2023, together with FAIRLY MADE®, we simulated the carbon footprint of an ORIGIN pair made from animal leather, using an average value corresponding to chrome-tanned bovine leather produced in Asia.

In this simulation, all other parameters of the model were kept identical (lining, sole, manufacturing processes, production location, etc.). On this basis, we estimate that a pair of MOEA ORIGIN sneakers emits on average around 78% less CO₂ equivalent than a comparable pair made from animal leather.

Finally, the carbon footprint is an indicator of a product’s climate impact. It does not reflect all possible environmental impacts, such as biodiversity, water consumption, or pollution.

Transparency and responsible communication

Environmental communication about products is regulated in France by several legal frameworks, notably the AGEC law (Anti-Waste for a Circular Economy) and the Climate and Resilience law, which aim to ensure the reliability and transparency of information provided to consumers.

We therefore provide this page to explain the methodology used to estimate the carbon footprint of our products. This indicator is intended to inform and help improve our practices. It does not constitute an environmental certification nor a guarantee of reduced environmental impact.
