ALROSA summed up its 2025 sustainability activities and achieved results, confirming its status as an industry leader in sustainable development. In 2025, the company achieved international recognition for carbon neutrality of its natural diamonds, strengthened its position in national and international rankings, and expanded its social, environmental and climate initiatives in the regions of its operations.

Sustainable Development: Climate, Ecology and Social Responsibility 

Key achievement of the year was the verification and certification of carbon neutrality of ALROSA’s diamond mining operations in Yakutia and the Arkhangelsk Region, as well as the negative carbon footprint of its rough diamonds. This was announced at the Saint-Petersburg International Economic Forum (SPIEF-2025), attended by key global diamond industry representatives from China, India and South Africa.

Following the stage of field studies, the company received a final verification report from the international auditing firm TÜV AUSTRIA Standards & Compliance. As a result, ALROSA became the first mining company in the world to confirm through science-based certification the carbon neutrality of its production facilities through CO2 absorption by kimberlite tailings, as well as the negative carbon footprint of its rough diamonds.

Further developing this project, in 2025 ALROSA announced the launch of Russia’s first CCS climate project, aimed at increasing the efficiency of CO2 absorption by kimberlite. This initiative will significantly contribute to achieving Russian national climate goals and establishing new industry standards. Validation of the climate project is planned for 2026. Its capacity could reach approximately 25,000 carbon units per year.

The company continued to implement its Climate and Environmental Strategy with targets till 2035, investing in energy efficiency, renewable energy development, responsible water use and biodiversity.

In December 2025, the Nakyn Stream gas pipeline to ALROSA’s production facilities at the Nakyn diamond field was commissioned. Its launch improves the energy efficiency of production through the use of cleaner energy sources, and contributes to achieving the goals of ALROSA’s Climate and Sustainable Development Strategies targeting the reduction of direct and indirect energy-related greenhouse gas emissions (Scopes 1 and 2).

In the regions where it operates ALROSA continues to implement large-scale social programs, including support for indigenous peoples of the North, infrastructure development, healthcare, and education. In 2025, as part of the development of a comfortable urban environment, a new gas supply system was commissioned in the town of Udachny, providing modern and efficient heating facilities for local residents.

Events: Dialogue, Expertise, and International Agenda
Throughout the year, ALROSA actively participated in key international and national events, shaping the natural diamond industry’s agenda on sustainable development.

ALROSA provided a platform in Russia for summarizing the results of the COP-30 conference held in Brazil, hosting leading experts at the roundtable “COP-30: Expectations and Results”. Additionally, at the “UN Global Compact Network Russia (COP-30)” session, ALROSA presented its achievements in combating climate change and confirming carbon neutrality of natural diamonds, discussed the challenges and prospects for sustainable development of indigenous peoples traditional way of life in the context of the climate agenda. Supporting indigenous peoples of the North remains a key priority for the Company: in 2024 alone, over 1.7 billion rubles were allocated to measures aimed at supporting their socio-economic development.

Furthermore, ALROSA co-organized the 6th Northern Forum on Sustainable Development in Yakutsk, presenting innovative low-carbon development practices and projects to restore Arctic and Northern ecosystems.

The results of the project on negative carbon footprint of natural diamonds verification were also presented by the Company at the India International Jewellery Show Premiere 2025 Mumbai, India, the largest international jewelry exhibition in Eurasia, in the heart of the world’s largest diamond trading and cutting center. As part of its efforts to promote international industry cooperation on sustainable development, in 2025, ALROSA together with the African Diamond Producers Association, participated in a roadshows in South Africa and Namibia to promote the Sustainable Diamond Standard being developed within this industry organization, based on which ALROSA conducted a pilot audit last year.
