Implementing energy efficiency programmes
In order to reduce the impact of its suppliers emitting the most CO2, DECATHLON is helping them analyse their energy management maturity and then implement suitable efficiency programmes.

Encouraging suppliers to adopt practices having less impact on the environment.
In 2025, 63% of DECATHLON’s total CO2 emissions were derived from the extraction of raw materials and the production stages required to manufacture sports goods. It is essential that DECATHLON works with its suppliers to reduce its footprint along its entire value chain. Since the energy used in production worldwide is still generated primarily using fossil fuels (coal, gas and oil), DECATHLON decided in 2017 to assist its suppliers in their transition.
DECATHLON’s production decarbonisation
strategy is structured around several pillars:
- Measuring the energy consumed
- Obtaining supplier commitment to reduce their footprint
- Deploying energy efficiency programmes
- Constructing coal elimination trajectories
- Deploying renewable energy (in order of priority):
- by installing new production capacities
- by participating in existing off-site projects
- by purchasing Energy Attribute Certificates (EAC) (in addition)
- Identifying collaborative opportunities and economic incentives for supplier decarbonisation.
These pillars are assessed during environmental audits for the relevant sites, and given that this strategy is a priority for the company, they are promoted more broadly with all suppliers.

Apparel component manufacturer Tran Hiep Thanh, an important industrial partner for DECATHLON in Vietnam, has drastically reduced its carbon emissions by replacing coal with biomass.
Biomass is a fuel made of organic waste that can be burnt to generate heat, which can be used for manufacturing or converted into electricity.
Using biomass as a source of fuel is a Low Carbon Process.
