Outdoor Brand Mammut Commits to Renewable Energy, Recycled Materials

Mammut is making a climate commitment to phase out fossil fuels and switch to 100 percent renewable energy to power the manufacturing of its products by 2030.

The Swiss outdoor apparel, footwear and gear brand has also committed to ship goods on zero-emissions cargo ships by 2030 and slash air freight emissions in half by the close of the decade. In addition, its new climate strategy sets commitments to recycle fossil fuel-based fabrics such as polyester and polyamide in a closed loop, bringing the brand closer toward a circular, and less wasteful, business model. What’s more, the brand plans to pursue low-carbon materials as it decouples from fracked fabrics. applauded the move less than a month before the release of the international environmental advocacy organization’s annual Fossil Free Fashion Scorecard, ranking the climate commitments of 47 top fashion companies.

“Mammut’s announcement couldn’t have come at a more crucial time for our global climate,” said Muhannad Malas, senior climate campaigner at “With the UN’s Intergovernmental Panel on Climate Change warning that we are at ‘code red for humanity,’ we know we need massively polluting industries like fashion to step up and invest in bold solutions to address their outsized emissions. By making a commitment to transition to renewable energy in its supply chain, ship its cargo on zero-emissions vessels and reduce its reliance on fracked fabrics like polyester, Mammut is setting a standard the rest of the fashion industry must follow.”

Mammut CEO Oliver Pabst said the company understands that it plays an important part in the joint journey to Net Zero.

“We take the responsibility to think boldly and dare to reach high and we are committed to inspire others to be part of this global journey,” Pabst said.

“Commitment is not enough; we need to start transforming–now,” Huber said. “Every decision, every action we take in the 2020s will determine our future. It’s time to use our collective voices to demand a better future for people and the planet. It’s not too late, but we need to act now.”

Mammut aims to reduce 55 percent of its absolute greenhouse gas (GHG) emissions in its supply chain and to reduce 70 percent to 80 percent of its absolute GHG emissions in its owned and operated facilities. This includes tracking and publicly reporting GHG emissions and energy use for the most significant Tier One and Tier Two suppliers by applying the HIGG Index FEM until 2023.

Stating that approximately 95 percent of the fashion industry’s climate pollution is hidden in complex supply chains, Mammut said its plan to address this pollution head on through a combination of renewable energy, coal phaseout and zero-emissions vessels is significant.

The company will also eliminate materials such as leather sourced from practices that contribute to deforestation and invest in circular business models such as repairability, re-commerce and recycling.
