The relations with such workers are mainly formalised through independent contractor agreements.

Such agreements are typically made for temporary work, with no prevailing type of activity specified.

The Company uses statistical reporting forms adopted in Russia to record energy consumption data. Conversion factors into terajoules (TJ) are based on the GRI 3.0 Guidelines and Engineering Journal, Russian R&D reference book.

The Company does not consume cooling energy in its operations. It also does not sell cooling or steam energy

To calculate GHG emissions, the Company used relevant global warming potential (GWP) values from the IPCC’s Sixth Assessment Report, which are 1 for CO₂, 27 for CH₄, and 273 for N₂O.

The calculation includes the following greenhouse gases: carbon dioxide (CO₂), nitrous oxide (N₂O), and methane (CH₄), with emissions of other greenhouse gases either absent or insignificant.

Biogenic CO₂ emissions are not applicable

In 2024, GHG emissions avoided totalled 259.7 kt of CO₂ equivalent, including 79.2 kt of Scope 1 emissions avoided as a direct result of energy efficiency initiatives, and 180.5 kt of Scope 2 emissions avoided through direct bilateral power purchase agreements (PPAs) for low‑carbon electricity.

The methodology for calculating emissions avoided as a direct result of energy efficiency initiatives is based on the calculation for Disclosure 302‑4 (an estimate of the emissions avoided as a result of reduced energy consumption)

H&S management at Nornickel

Sustainability report 2022, page 312

Health and safety risks are identified and assessed at all Group entities covered by the Report, either on an annual basis or ad hoc, as described in the STO KISM 121‑211‑2017 corporate integrated management standard or similar standards in place at Group entities. The quality of these processes is ensured through the alignment of assessment requirements with the above standards. Employees can report work‑related hazards through the following channels:

• Orally to their immediate supervisor
• Through problem‑solving board installed at all sites
• By sending messages to the relevant H&S unit
• Through authorised representatives in H&S committees
• At staff meetings
• By submitting a work refusal form

All work‑related injuries are investigated by a dedicated commission as stipulated by national laws

The number of fatalities as a result of work‑related ill health is not disclosed due to the confidential nature of this information and the absence of permission for its use by the government agencies responsible for its storage and record‑keeping.

Information on work‑related ill health among contractors is also not disclosed, as it is not possible to definitively determine whether such cases are directly attributable to work performed at the Company’s facilities.

Information on the types of work‑related ill health and the contributing factors is not disclosed due to the lack of consolidated records. The Company will consider developing an appropriate accounting system within the next three years
