Russian diamond miner Alrosa has implemented Russia’s first Carbon Dioxide Removal (CDR) project, capable of absorbing up to 25,000 tonnes of CO₂ equivalent annually.
Developed at the company’s Mirny-Nyurba Mining and Processing Plant in Yakutia, the project harnesses the natural carbon-absorbing properties of kimberlite, the diamond-bearing rock. Through an enhanced mineral carbonation process, atmospheric carbon dioxide is converted into stable minerals and permanently stored in geological formations.
“This is the first project of its kind in Russia and one of only a few globally,” said Alexey Masanov, Head of Alrosa’s Centre for Innovation and Technology.
The project falls under the climate category of Enhanced Weathering of Minerals, a recognised carbon-removal approach.
The development follows Alrosa’s 2025 achievement of becoming the first diamond producer to secure verified carbon neutrality for its natural diamonds. Independent verification by TÜV Austria confirmed a negative carbon footprint of -0.71 kg CO₂ equivalent per carat.
