Irkutsk Oil Company (IOC) has developed a biodiversity conservation program. The measures will ensure consistency and increase the effectiveness of measures to preserve natural ecosystems.

The program provides for a set of measures to prevent animal deaths on roads, protect migration routes, and maintain the cleanliness of water bodies. A handbook entitled “Rules of Conduct for Employees on the Preservation of Biological Diversity” has been developed and published specifically for employees and contractors, including information on 18 species of animals, 15 species of plants, and two rare and protected species of fungi.

To develop the program, IOC conducted biota studies in the Zapadno-Yaraktinsky subsoil block and the Yaraktinsky field, as well as in the Verkhnetirsky, Bolshetirsky, and Mirninsky subsoil blocks. The results are integrated into the IOC’s geographic information system. Web maps showing the habitats of rare species help minimize environmental impact during day-to-day operations, work planning, and route selection.

The company will continue its biodiversity research in other areas and deposits. In 2026, it will conduct a repeat study of the Zapadno-Yaraktinsky subsoil block and the Yaraktinsky field to assess the dynamics of changes.

Preserving biodiversity is one of IOC's key priorities in line with its ESG agenda. The company actively implements various environmental initiatives: it holds community cleanup days, environmental lessons, organizes tree planting, installs animal feeders, and stocks the Lena River and the Bratsk and Vilyui reservoirs with fish. In 2024, the company also initiated the project Reintroduction of the Forest Bison in Central Yakutia.
