A few words about us

Limiting global warming to 1.5°C implies reaching net zero CO₂ emissions in 2050 according to the IPCC. Next to substantially reducing emissions, this target will only be possible by globally deploying carbon removal solutions at the scale of billions of tons of CO₂.

Neustark is a leading provider in this rapidly growing field, having developed a solution to permanently store CO₂ from the air in recycled mineral waste such as demolished concrete.

Our first solutions have been deployed in Switzerland and Europe and are already capturing and storing tons of CO₂ every day. We are currently scaling up our operations and carbon removal impact globally – on the road to our ambition of removing one million tons of CO₂ in 2030, and beyond that.

Our vision

We are enabling permanent CO₂ storage – for a bright future of all generations on our planet.

Where we operate

We have installed our capture technology at the sites of partnering biogas plants… as well as our storage technology at the sites of partnering concrete recycling plants. Stay tuned: our footprint and impact are growing quickly!

What makes us different


Neustark holds all the pieces of the value chain together: from sourcing the CO₂ to permanently storing it to issuing CDR certificates.


Mineralization is one of the few technologies that warrants carbon removal with a permanence of thousands to millions of years.


The impact we deliver – i.e. the tons of CO₂ we store in demolished concrete – is permanent, measurable, and verified by Gold Standard.


Neustark offers CO₂ source and storage solutions in proximity of each other in each region in which we are present.


Our capture (at source site) and storage (at recycler site) technologies are highly scalable – and merge into our partners’ existing operations.

impact now

We make a tangible impact now: neustark removes CO₂ permanently – already today, even more tomorrow.
