Alrosa has unveiled a pioneering carbon removal initiative at its Mirny-Nyurba Mining and Processing Plant in Yakutia, marking a significant advancement in the company's sustainability efforts.
The project is designed to capture up to 25,000 tonnes of carbon dioxide equivalent each year by leveraging the natural characteristics of kimberlite, the rock that hosts diamonds. Through an enhanced mineral carbonation process, carbon dioxide from the atmosphere is transformed into stable mineral compounds and securely locked within geological formations for long-term storage.
According to the company, the initiative represents a major milestone in the field of carbon removal and positions the mining sector as a potential contributor to climate mitigation efforts. The project operates within the Enhanced Weathering of Minerals category, a recognised approach focused on accelerating natural carbon-capturing processes.
The launch builds on Alrosa’s broader environmental commitments. In 2025, the company reported achieving verified carbon neutrality for its natural diamonds, supported by independent assessments that indicated a negative carbon footprint per carat.
By combining mineral resources with innovative climate technologies, Alrosa is exploring new ways to reduce atmospheric carbon while advancing more sustainable mining practices.
