In a bold move towards combating climate change, Mammut and partners have launched an innovative project focused on carbon dioxide (CO2) removal and its storage in concrete. This groundbreaking initiative is championed by the renowned climber, Adam Ondra. Watch here what Adam has to say about the project and how it resembles a challenging climb.

Concrete action: Mammut’s revolutionary CO2 removal initiative

As a leading outdoor sports company, Mammut thrives on the beauty of nature. However, the production of durable equipment and the travel associated with mountain adventures contribute to carbon emissions. To address this, we have developed an ambitious decarbonization strategy, “Do Our Best, Remove the Rest,” aiming to halve our emissions by 2030 and achieve net zero by 2050. In addition to the significant reduction efforts being implemented at Mammut and throughout our supply chain (a 13% reduction in CO2 emissions from 2022 to 2023), we are also exploring innovative ways to remove remaining carbon emissions from the atmosphere. 

From gas to concrete 

But what is this particular project about? The Danish tech start-up Klimate is central to this project, bringing together all stakeholders. ARC in Copenhagen captures up to 4 tons of CO2 daily from the waste-to-energy plant’s flue gas. Bofort provides the ISO tanks for transporting liquefied CO2 to Finland, where Carbonaide integrates it into their sustainable concrete production process, permanently binding the CO2. We at Mammut are the “buyers” that have committed to decarbonizing a total of 90 tons of CO2 by the end of 2025.

Leading by example

Tobias Steinegger, Head of Corporate Responsibility at Mammut, emphasizes the importance of this cooperation: “Through this partnership, we aim to achieve tangible results in carbon removal and inspire other companies to eliminate their residual emissions after significant reduction efforts.” 

Mads Emil Dalsgaard, Co-CEO of Klimate, adds: “This facility is just the beginning. We’re proud to have Mammut and Adam Ondra supporting this project, paving the way for future scaling and development.”

Adam Ondra’s symbolic ascent

The initiative is visually represented by Adam Ondra climbing the artificial route on the exterior of CopenHill, one of the tallest structures of its kind globally. Adam compares reaching net-zero to a complex climb: “This could be seen as doing the first moves or grabbing a tiny intermediate hold. But the important thing is that we are moving in the right direction.” 

This partnership reflects a shared vision for a sustainable future and a proactive approach to environmental responsibility. It is not just a statement but a tangible action against the climate crisis we are facing.
