The GuardianNegative CO₂ cement factory in Norway
Norway has built the world’s first carbon-negative cement plant — and it eats CO₂ as it works
In a windswept fjord-side facility, Norwegian engineers have just flipped the script on one of the world’s dirtiest industries. Cement — which usually accounts for 8% of global CO₂ emissions — is being made here in a factory that actually removes carbon from the air.
The secret lies in a new process that binds captured CO₂ into the cement itself using a mineral called olivine, which naturally absorbs CO₂ as it hardens. But it doesn’t stop there — the factory is powered entirely by hydropower and uses heat recapture systems to drive the reaction with minimal energy loss.
The result is a fully carbon-negative production cycle: for every ton of cement produced, 1.2 tons of CO₂ are removed from the environment. And it’s not a prototype. This is a functional commercial plant already delivering product to regional construction projects.
