Mammut: Do your best, and remove the rest

Mammut's purpose is to inspire love for the mountains, and passionately develop high quality products that enable all outdoor enthusiasts to experience the power of the mountains. Inspired by the changes they see in the mountains around them from their home-base in the Swiss Alps, and, driven by the climb in front of us all, their goal is to reach net zero by 2050 the latest.

Why carbon removal

Mammut’s Journey with Carbon Removal

Mammut has adopted sustainability initiatives that include a science-based reduction target, with focus on scope 3 emissions, the three main pillars are lower-impact materials, renewable energy along the supply chain and circularity, and removing what they cannot reduce. The company has a history of working with sustainability, from social sustainability with the aim of implementing a more ethical supply chain that started several decades ago to enhanced chemical management and animal welfare. Today, the priority is tackling the climate crisis and achieving company–and global–carbon net zero by 2050 latest.

This is where their motto “Do our best, remove the rest” comes into play. By implementing ambitious reductions along their own value chain and engaging with carbon removal partners, Mammut is striving to do just that.

We realised that tackling atmospheric excess through removals was a must-do and goes beyond traditional, avoidance-based carbon offset credits. Through our partnership, we were able to dive deep into understanding and strategy. This meant investing in impactful removals and exploring different partners and methods. Our goal isn't just to talk the talk but to recognise the need to aim for a future of net zero emissions. This awareness drives us to shift funds towards both reducing and removing emissions.

Measure, Reduce, Remove

Starting in 2018, Mammut began calculating a baseline of emissions to direct their main focus of impact and responsibility to climate. After measuring and strategising how to reduce throughout the business, and increasingly implement these measures, they started to shift their focus to develop their carbon removal strategy.

Klimate and Mammut were introduced through a trusted partner, providing a strong foundation for partnership. Now, the two have collaborated to provide carbon removal associated with a number of different activities, including decarbonised trail running collection, consumer mountain events, and athlete sponsorships.

Over time, Mammut and Klimate aim to  develop their strategy to shift carbon removal portfolios to more permanent methods, thereby aligning with the Oxford Offsetting Principles.

What’s been accomplished so far:

  • 610 tco2e removed
  • Emissions period: 31 Dec. 2021-present

Strategy in Action: Mammut Mountain Days

One example of our collaborations includes an events-based removal strategy for Mountain Days. This three-day gathering of the outdoor community full of hiking, climbing, and events is in Zermatt, Switzerland. Carbon removal is just one piece of the strategy to create a more sustainable experience. Their dedication to provide this event in an environmentally more responsible manner sets a great example for contributing to climate action beyond conventional offsetting. True to their strategy to do their best and remove the rest, Mammut implemented a number of sustainability strategies to reduce the impact of the event alongside investing in carbon removal. Some of these interventions include:

  • Offering outdoors activities not harmful to the environment: mountaineering, climbing, hiking, via ferrata, trail running. Also: athlete talks, workshops, and films at the base camp.
  • All participants sleep in tents – they can be purchased at the end of the event at a heavily discounted price.
  • Vegetarian food (vegan option for vegan participants)
  • Transportation during the event: train, mountain cable, funicular or by foot. All staff, athletes, mountain guides and participants are asked to come to Täsch by public transportation.*

This action was met with a great response from stakeholders, leading to further events-based interventions since.

Moving forward

Developing the Road to Net Zero Together

Over the years of this partnership, Klimate has aided Mammut in developing and diversifying their carbon removal strategy. By investing in more methods, and a higher share of permanent methods, over time, setting Mammut up for success in their climate goals.

This partnership has allowed us to explore different methodologies, projects, and exposed us to expertise in the industry. With the portfolio, we are able to invest in more durable solutions over time, in balance with nature-based solutions, and also remain in a pioneering role in the industry. This process makes carbon removal investment tangible and transparent, setting us up to help scale the carbon removal industry as well as our investment [to more collections] over time.
