Fight climate change with direct air capture


Remove CO₂ from the air with Climeworks' direct air capture technology.

As Special Expedition members of Climeworks, we help them to scale their technology to remove 100kg of CO2 from the air a month. Climeworks uses a technology called ‘direct air capture’ to capture carbon dioxide directly from the air. When the removed CO₂ is combined with underground storage, it allows the permanent removal of excess and legacy CO₂ emissions, which can no longer contribute to climate change.

Climeworks - The challenge ahead

Our mission is clear: to protect our planet and ensure a livable future for generations to come, the IPCC states that global warming must be limited to 1.5°C. To maximize our chances of achieving this, the world needs to reach net-zero emissions by 2050.
So how do we get there? Well, emissions reductions are the absolute priority in this quest — we all have a responsibility to reduce our carbon emissions. But to truly enable global net zero, we also need carbon dioxide removal solutions, such as direct air capture and storage (DAC+S), to neutralize our unavoidable and historic emissions. Critically, we need to remove billions of tons of CO₂ from the air by 2100 to keep global warming in check. That’s why we’re on a journey to scale our DAC+S technology to gigaton capacity.

Pioneering a way forward

The science is clear: to keep global warming below 1.5°C, we need both drastic emissions reductions and carbon dioxide removal. At Climeworks, we’ve developed an innovative technology called “direct air capture” to remove excess CO₂ from the air so it can no longer contribute to climate change. In collaboration with high-quality CO₂ storage, we provide a carbon removal service that’s permanent, measurable, and scalable.


We combine direct air capture technology with permanent underground storage, where captured CO₂ is turned into stone and stored safely for thousands of years.


There’s no uncertainty about how much CO₂ we remove because we can measure exactly, and our service is third-party certified.

Climeworks Scalable


Our technology is highly scalable and location independent. There’s global potential for direct air capture and storage from the Middle East to North America.

The role of Mammoth’s CO₂ collector containers

Climeworks Mammoth CO2 Collector

The CO₂ collector containers (abbreviated as CCs) are a core component of Climeworks’ direct air capture (DAC) plants: they are the ones capturing CO₂ from the air. Mammoth will consist of 72 CCs (in contrast to the 8 CCs deployed at Orca), three of which are stacked together on one foundation (vs. two at Orca).
The CCs were fully developed and designed by Climeworks and represent the modularity of Climeworks’ DAC technology. Modularity means that units are produced in standardized dimensions, which allows for easy assembly and flexible arrangement. Climeworks’ CCs were designed to enable mass production: the handling of the CCs during construction is simple thanks to its dimensions – they can be flexibly moved around with a reach stacker (a vehicle that can stack, load or unload containers) and are easily stackable. This, in turn, simplifies maintenance work and enables the implementation of upgrades by improving and optimizing the technology and its operations throughout the lifetime of the facility.
This can be compared to solar panels, which are the modular units of photovoltaic systems: panels can be flexibly added to the system in order to increase the voltage required. They are also easy to maintain or exchange in case of damage.
