Mammut has launched a partnership to capture industrial carbon emissions and permanently store them in concrete. Carbon to concrete will establish a new model for sustainable manufacturing.

Outdoor equipment manufacturer Mammut has launched an innovative carbon to concrete project that captures industrial emissions and permanently stores them in concrete, establishing a new model for sustainable manufacturing in the outdoor industry.

The Swiss company has partnered with Danish climate technology startup

, waste management facility ARC, transportation specialist Bofort, and concrete manufacturer Carbonaide in a multi-stage carbon capture and storage initiative to process 90 tons of CO2 by the end of 2025.

The carbon to concrete project begins at ARC’s waste-to-energy plant in Copenhagen, where up to four tons of carbon dioxide are captured daily from flue gas emissions. This captured CO2 is then liquefied and transported in specialized ISO tanks provided by Bofort to Carbonaide’s facilities in Finland. There, the carbon dioxide is permanently integrated into concrete during manufacturing, effectively removing it from the atmospheric cycle.

This initiative represents a practical step in Mammut’s broader environmental strategy, which aims to reduce the company’s carbon emissions by 50% by 2030 and achieve net-zero emissions by 2050. The company has branded this approach as “Do Our Best, Remove the Rest,” acknowledging the current necessity of manufacturing processes that produce emissions while actively working to mitigate their environmental impact.

The outdoor equipment industry generates significant carbon emissions through its manufacturing processes. According to industry data, a single technical outdoor jacket can produce up to 20kg of CO2 during its production, while a pair of climbing shoes generates approximately 8kg of CO2. The global outdoor equipment industry’s annual carbon footprint is estimated at 66 million metric tons of CO2 equivalent, comparable to the emissions of entire small countries.

Major outdoor brands have taken varying approaches to environmental responsibility. While some focus on recycled materials and renewable energy in manufacturing, Mammut’s concrete storage solution represents a new direction in addressing unavoidable emissions. The industry has seen a 15% increase in sustainability initiatives since 2020, with carbon capture and storage emerging as a promising frontier.

The collaboration addresses a fundamental challenge in outdoor sports equipment manufacturing: the need to produce durable, protective gear while minimizing environmental impact. Outdoor equipment must meet rigorous safety and performance standards, requiring materials and processes that generate significant carbon emissions throughout their production cycle.

If implemented industry-wide, carbon to concrete storage could reduce the outdoor equipment sector’s carbon footprint by up to 30% within the next decade. The technology shows particular promise for addressing emissions from high-impact processes like waterproof membrane production and synthetic material manufacturing, which account for approximately 40% of the industry’s total emissions.

To symbolize this environmental commitment, the project launch featured Olympic athlete and multiple World Champion climber Adam Ondra ascending an artificial climbing route on Copenhagen’s CopenHill facility, one of the world’s tallest artificial climbing walls. This facility, built on the same waste-to-energy plant where the carbon capture process begins, represents the intersection of urban development, waste management, and environmental innovation.

The project structure demonstrates how cross-industry collaboration can create practical solutions for carbon removal. Klimate’s role as coordinator brings together industrial carbon capture, specialized transportation, and innovative concrete manufacturing processes, creating a complete chain from emission to permanent storage.

This initiative represents a shift in how manufacturers approach residual emissions – those that cannot be eliminated through current technology and processes. Rather than relying solely on traditional carbon offset methods, the carbon to concrete project physically removes and permanently stores carbon dioxide in a widely used construction material.

The concrete industry, which accounts for approximately 8% of global carbon emissions, could benefit significantly from this technology if implemented at scale. By incorporating captured CO2 into concrete production, the project removes carbon from the atmosphere and potentially improves the concrete’s properties while reducing its overall carbon footprint.

were adopted by 25% of outdoor equipment manufacturers, the industry could reduce its annual emissions by approximately 16.5 million metric tons of CO2 equivalent by 2030. This reduction would be equivalent to removing 3.6 million passenger vehicles from the road for one year.
