World Water Day, established by the UN General Assembly, is celebrated annually on March 22. This date is intended to draw humanity's attention to the need to conserve and use one of nature's most valuable resources—freshwater.
Rosneft is committed to the rational use of water resources throughout its operations and takes measures to protect and replenish them. The Company ensures responsible water use at all stages of the production cycle. The corporate Environmental Efficiency Improvement Program and plans for modernizing production facilities include further reductions in water intake from natural sources, an increase in the share of recycled and reused water, the environmentally sound use of produced formation water, and the implementation of modern wastewater treatment systems.
The Company's share of recycled and consistently reused water exceeds 93.7% of the total water used for production purposes. ISS (Institutional Shareholder Services), a leading international investment and consulting agency, highly praised Rosneft's environmental performance, including placing the Company among the leaders in its environmental ratings. For the third year in a row, RAEX, a leading Russian non-credit rating agency, has awarded Rosneft an "AA" ESG rating, confirming the Company's exceptional sustainability performance, including environmental performance.
Rosneft subsidiaries maintain high environmental safety standards in water management in the regions where they operate.
In the oil refining and petrochemicals sector, the Achinsk Oil Refinery in Krasnoyarsk Krai reconstructed its treatment facilities in 2025 to improve the efficiency of water reuse. As a result of modernizing the water supply network, cooling towers, and automating process water cooling systems, the share of water reused for the plant's production needs increased to 95%.
Rosneft is also implementing effective natural water treatment solutions in its production facilities. Rosneft's refineries in the Samara region are using phytofiltration technology in their wastewater post-treatment units. The Kuibyshev Oil Refinery pioneered this implementation, using plants such as water hyacinths (Eichhornia), pancratium, and sweet flag to achieve high levels of wastewater disinfection. Eichhornia seedlings have proven themselves to be effective in the treatment facilities of the Syzran and Novokuibyshevsk Oil Refineries.
The Novokuibyshevsk Oil Refinery in the Samara Region is implementing a comprehensive environmental program, one of the focuses of which is water resource protection. Its implementation has improved wastewater quality by 36% over the past few years. One of the key projects is the commissioning of an innovative water treatment unit with a membrane bioreactor. This has enabled the plant to return treated wastewater to the water recycling system. The project has resulted in the plant's water recycling rate reaching 97%.
One of Rosneft's key environmental investment projects, the biological treatment plant (BTP) complex at Bashneft's Ufa group of oil refineries, has processed 185 million cubic meters of wastewater since its launch in 2019. The BTP not only serves Bashneft's refineries but also provides high-quality wastewater treatment for over 40 enterprises in Ufa's northern industrial zone, as well as stormwater runoff. Membrane reactor technology removes impurities and microorganisms from the wastewater. As a result, water quality meets standards for fishery water bodies.
The Angarsk Petrochemical Company in the Irkutsk region uses a closed-loop water supply system—the company's recycling system reuses 90% of its water. The company's treatment facilities also handle wastewater from the city of Angarsk and industrial facilities.
In the oil and gas production sector at the Vankor cluster fields located in the Yenisei River basin and its tributary, the Bolshaya Kheta, RN-Vankor environmentalists continuously monitor water bodies and the coastal strip near production sites. RN-Vankor specialists, working with accredited laboratories, regularly monitor the condition of treatment facilities and analyze the environmental conditions and biota in water bodies. Wastewater parameters are also monitored across 23 parameters. In 2025, RN-Vankor environmentalists collected 316 wastewater samples and 664 samples of natural water and bottom sediments.
With the support of RN-Nyaganneftegaz, construction has begun on a modern water treatment facility in Nyagan. This facility will triple the capacity of the city's water treatment facilities, up to 30,000 cubic meters of water per day, and will provide more than 60,000 Nyagan residents with high-quality drinking water that meets modern sanitary standards.
The Samotlor field has a modern reservoir pressure maintenance (RPM) system, which has eliminated the need to draw water from open sources. Produced water purified by gravity settling in special tanks is used to maintain reservoir pressure. This ensures the RPM system operates in a closed-loop process. Samotlorneftegaz also uses produced water during multi-stage hydraulic fracturing operations. The implementation of this innovative method has already eliminated the need to draw over 300,000 cubic meters of water.
In 2025, Orenburgneft continued its water consumption reduction efforts. The company at the Pokrovskoye field converted its injection wells to pumping produced water from the Pokrovskaya well-well pumping station.
Samaraneftegaz also uses water separated from oil-containing liquids during production in its reservoir pressure maintenance system. This saves natural resources and improves the efficiency of production processes at the company's facilities.
In the petroleum product distribution sector, RN-Northwest equipped restrooms at Rosneft filling stations in St. Petersburg with automated water drainage systems, saving water consumption and improving customer comfort. In the Leningrad Region, the Vladimirovsky Country Hotel Complex conducted maintenance on its treatment facilities, improving water purification quality. An innovative drinking water supply system was introduced in the Vladimirovsky's guest lounges, reducing water consumption.
The Company's subsidiaries continuously implement measures to preserve and enhance aquatic bioresources in the regions where they operate. They replenish valuable fish populations in watersheds, conduct environmental cleanups of river and lake shorelines, improve natural springs, and promote a culture of rational and responsible consumption of natural resources, as well as conduct public education.
As part of a responsible waste management program, Saratov Oil Refinery employees collected 82 kg of plastic bottle caps and purchased juvenile herbivorous fish—common carp, silver carp, and grass carp. These fish species help clear the Volgograd Reservoir of excess vegetation, which is essential for preserving its ecosystem.
One of the Company's Moscow offices received a gold Green Office certificate for its success in reducing consumption of all types of resources, including water. Thanks to the implementation of efficiency measures, water consumption was reduced by 20%.
Responsible environmental stewardship is an integral part of Rosneft's corporate culture and one of its key operating principles. Demonstrating its commitment to achieving the UN Sustainable Development Goals, the Company is implementing a comprehensive water conservation program, including the introduction of advanced technological solutions.
