Trailrunning Collection That Sucks CO2 From Air

Forget carbon offsets – Mammut introduces its Aenergy trail running series, 100% decarbonized using Climeworks’ “Direct Air Capture” tech.

Mammut’s return to the trail running segment means more than just covering distance: All CO2 emissions generated in the production of the collection are actually removed from the atmosphere as part of a cooperation agreement with Climeworks and other partners. Decarbonization pays into Mammut’s commitment to reach its goal of Net Zero by 2050. In May, the Strava Challenge “Race to Zero” will inspire runners to actively undertake something for climate protection.

Highlights of the collection include the Aenergy TR HS Hooded Jacket, the Ae​​nergy TR WB Hybrid Vest, the Aenergy TR 2 in 1 Shorts, the Aenergy TR 5 Race Vest and the Aenergy TR BOA® Mid Trail Running Shoes.

Light, functional and 100% decarbonized

The entire 2023 Mammut trail running collection carbon footprint is calculated to 279t CO2-eq – all of which has been 100% decarbonized with high-quality Carbon Removal Credits. To achieve this, Mammut has enlisted the support of partners such as Climeworks. Climeworks is a pioneer and leading company in the removal of CO2 from the air with its “Direct Air Capture” technology. This means that the CO2 removed is stored safely and permanently or recycled as a raw material. ​

“At Mammut, our climate strategy is focused on reducing our CO2 emissions along our value chain,” shares Adrian Huber, Head of Corporate Responsibility at Mammut.

“Therefore, we are committed to using sustainable materials, renewable energy, supply chain change and circular business models. Teaming up with partners like Climeworks is an important part of our overall climate strategy and supports us in removing the remaining emissions.”

Strava Challenge “Race to Zero”

Throughout the month, Mammut has planned running meets and local Challenge segments in various cities. Those who show their segment badge at participating stores after completing 20, 40, 60, 80 or 100 kilometers will receive discounts and prizes.

All finishers will also receive a 20% discount on Mammut clothing and a 20% discount on CO₂ removal at One will additionally be entered into a drawing to win one of five new 100% decarbonized trail running outfits from Mammut.

For every 10,000,000 miles run, Climeworks will remove 10 tons of CO₂ from the air so it can no longer contribute to climate change. The new trail running collection will be available from spring exclusively online at and at selected specialist retailers.

All information and participation from 24. April 23 can be found here.
