A rating to compare the environmental impact of products

A product's environmental impact is calculated for its entire life cycle using various indicators. An overall rating (ABCDE) is given, allowing you to easily identify products with the best environmental performance by comparing similar products to each other (T-shirts, bottoms, backpacks etc.).

Decathlon openly displays the environmental ratings of its products. Find out more:
