ALROSA has published its 15th Annual Sustainability Report, outlining the Company’s strategy, operational scale and 2025 performance across key sustainability areas. The Report also highlights ALROSA’s contribution to Russian National Development Priorities and the UN Sustainable Development Goals.

“Over the past year, ALROSA has once again demonstrated its ability to operate effectively in a rapidly changing environment and to address complex challenges and risks. The Company not only maintained its leading position in the global diamond mining industry and delivered solid financial results, but also strengthened its commitment to sustainable development as national non-financial reporting standards continue to evolve. Responsible business practices have provided the Company with important advantages, enabling us to adapt quickly to changes in the global diamond market, build an effective system for managing sustainability-related risks and seek new opportunities. The well-being of local communities, the environmental matters and cultural heritage in the regions where we operate remain our top priority, as reflected in our ongoing efforts’’, said Pavel Marinychev, CEO of ALROSA.
