Sustainability Practices

Mammut takes wide-ranging measures to protect biodiversity, reduce its consumption of water, energy, and other resources, avoid waste, and combat climate change.

Mammut only uses a tiny proportion of organic materials such as organic cotton or recycled materials such as recycled cotton, recycled polyester, and regenerated nylon.

It uses natural materials without relevant certifications, such as regular cotton or linen, or synthetic petroleum-based fibers such as polyester, nylon, acrylic, and more.

Mammut also uses a small proportion of semi-synthetic fibers or regenerated cellulosic fabrics such as Tencel lyocell, modal, and viscose.

Tencel is an eco-friendly fiber made with wood pulp from FSC-certified sustainable forests. But only a tiny proportion of the materials used by Mammut are environmentally friendly and sustainable.

Mammut publishes a list of all its manufacturers and many of its processing facilities on its corporate website. It strives to ensure fair and safe working conditions in all factories where its products are made.

The 2022 Fashion Transparency Index gave Mammut a score of only 26% based on how much the group discloses about its social and environmental policies, practices, and impacts.

Mammut manufactures its clothes in Turkey and many other East Asian countries, where human rights and labor law violations happen every day.

The Swiss clothing retailer does show some labor certification standards that could ensure good working conditions, decent living wages, health, safety, and other crucial rights for workers in its supply chain.

Mammut doesn't have any code of conduct that applies to all its suppliers and subcontractors based on the regulations set by the International Labor Organization (ILO).

Mammut relies on third-party audits with or without notice to assess compliance with the FWF Code of Labour. It works to improve the working conditions in its factories.

Mammut doesn't use exotic animal skin, hair, fur, or angora. But it uses leather, wool, silk, and down feathers to manufacture many clothing pieces.

These animal-derived materials are cruel and unethical. They also harm the environment by producing greenhouse gases and waste. More sustainable alternatives exist.

Sustainability Goals

Mammut has committed to reducing its environmental impact across the entire supply chain. It's committed to reaching net-zero emissions by 2050 at the latest.

Mammut aims to have 90% certified Bluesign PRODUCT and Bluesign APPROVED fabric in its collection by 2025. It will also remove all PFC-based treatments from its products by 2025.

Mammut aims to use 95% rPET for all its polyester products by 2025, building a more resilient and circular supply chain. And its goal is to use 100% organic cotton by 2025.
