Last month, Decathlon began grading the carbon footprint of apparel and shoes sold under its own brands. So far, the French retailer has labeled 63 percent of these products with a score from A to E (best to worst) and with a figure (in kilograms of CO2) calculated to reflect their full life cycle, including raw materials, manufacturing, transportation and disposal. The company says it has taken this step “above all to reduce the impact of product development,” which accounts for 86 percent of its CO² emissions. The figures appear on each product’s webpage as well.
