Scope 1 and 2 GHG emissions

When calculating Scope 1 and 2 GHG emissions in accordance with the GHG Protocol methodology, Nornickel takes into account carbon dioxide (CO₂), nitrous oxide (N₂O), and methane (CH₄). The quantification of Scope 1 and 2 GHG emissions includes the Company’s estimated prospective GHG emissions related to the implementation of the Sulphur Project at Nadezhda Metallurgical PlantHistorically, the GHG emissions provision for the Sulphur Project was estimated at 2.2 mln t of CO₂ equivalent. However, in the reporting year, due to planned reconfiguration of copper production, the prospective emissions from the implementation of the Sulphur Project are expected to be lower — approximately 1.2 mln t of CO₂ equivalent. This adjustment, among other factors, was also used to restate Scope 1 and 2 GHG emissions for previous reporting periods..

In 2024, direct and indirect GHG emissions (Scope 1 and 2) from production and other activities of the Nornickel Group, taking into account the adjustment for the Sulphur Project’sDue to plans to reconfigure copper production. GHG emissions provision, amounted to 8.6 mln t of CO₂ equivalent, including 8.2 mln t of direct emissionsIncluding a GHG emissions provision for the Sulphur Project at Nadezhda Metallurgical Plant and GHG emissions generated from heat and electricity supplies to the public. In 2024, actual direct and indirect GHG emissions (Scope 1 and 2) reached 7.5 mln t of CO₂ equivalent, including Scope 2 GHG emissions at 0.4  mln t of CO₂ equivalent as well as actual emissions from the Sulphur Project at Nadezhda Metallurgical Plant and GHG emissions generated from heat and electricity supplies to the public (the Sulphur Project GHG emissions provision at Nadezhda Metallurgical Plant was determined separately). and 0.4 mln t of indirect emissions.

Over the past four years, the Nornickel Group has maintained its downward trajectory in GHG emissions. In 2024, GHG emissions decreased compared to 2023 levels, driven by:

• lower per unit fuel consumption for heat and electricity generation as a result of optimising equipment operation modes at CHP plants
• favourable weather conditions in the Norilsk Industrial District during the autumn‑winter period
• updating of regional СO₂ emission factors for electricity supply within the energy systems of the Murmansk Region and the Trans‑Baikal Territory.

The Trans‑Baikal Division signed a direct bilateral power purchase agreement to purchase 124.9 million kWh of electricity from a certified low‑carbon energy supplier (a hydropower plant), driving Scope 2 GHG emissions down by more than 126 kt of CO₂ equivalent in 2024.

Comparison with global metals and mining peersDirect and indirect GHG emissions (Scope 1 and 2) from production and other activities of the Nornickel Group, including the Sulphur Project’s GHG emissions provision at Nadezhda Metallurgical Plant.

The comparison is based on available data for fiscal years 2023 and 2024. Peers include leading global diversified metals and mining companies: BHP Billiton, Rio Tinto, Vale, Glencore, and Anglo American.
