2.2. Approach to assessing the sustainability practices of suppliers of goods, works, and services
In 2023, the Company expanded the scope of suppliers subject to assessment for compliance with the Code requirements (the “assessment”) by including, in addition to mineral suppliers, suppliers of goods, works, and services. Nornickel conducts the assessment using the Supplier Self‑Assessment Questionnaire (the “Questionnaire”).

The assessment system was rolled out in phases:
- a pilot survey of a supplier sample The largest external suppliers of the Group’s Russian assets in terms of payment amounts in 2022. was conducted;
- feedback was analysed and the assessment methodology was initially refined.
- the supplier sample size more than doubled In 2023, the survey covered 14% of the Group’s total procurement volume; in 2024, more than 35%. ;
- the wording of the Questionnaire was updated to better align with the Code requirements and reflect stakeholder demands customers, regulatory requirements, ESG ratings);
- additional questions were included in the Questionnaire to account for the industry‑specific context of suppliers;
- questions were expanded to verify not only the availability of regulatory documents but also their practical implementation.
