Compared to the previous year (2024), Harmony Gold Mining's Scope 2 emissions (Unspecified Calculation Method) have remained relatively stable, indicating that Harmony Gold Mining's emissions have plateaued with no significant change in its energy consumption footprint.a
In 2025, Harmony Gold Mining reported its Scope 2 emissions using an unspecified methodology.a
In 2025, Harmony Gold Mining reported 993,368 metric tons of CO₂ equivalent (tCO₂e) of Scope 3 greenhouse gas (GHG) emissions, representing indirect emissions across its upstream and downstream value chain.a
The 2025 disclosure of Harmony Gold Mining includes a breakdown across 3 of the 15 Scope 3 categories defined by the GHG Protocol, matching the level of disclosure in 2024, demonstrating consistent Scope 3 emissions reporting coverage year over year.a
In 2025, Harmony Gold Mining reported total Scope 3 emissions of 993,368 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 100% of these emissions originated from upstream activities such as purchased goods and capital goods, while 0% came from downstream activities like product use, distribution, and end-of-life treatment.a
Compared to the previous year (2024), Harmony Gold Mining's Scope 3 emissions remained relatively stable, indicating that Harmony Gold Mining's emissions have plateaued with no significant change in its value chain footprint.a
In 2025, Harmony Gold Mining reported emissions for 3 out of the 15 Scope 3 categories defined by the GHG Protocol.a
The limited disclosure restricts visibility into specific emission sources across the company's value chain.
In 2025, the largest contributors to Harmony Gold Mining's Scope 3 emissions were:a
In 2025, Harmony Gold Mining reported Scope 1 greenhouse gas (GHG) emissions of 172,250 tCO₂e and total revenues of USD 4,175 millions. This translates into an emissions intensity of 41.26 tCO₂e per millions USD.a
In 2025, Harmony Gold Mining reported a Scope 1 emissions intensity of 41.26 tCO₂e per millions USD. Compared to the peer group median of 94.27, this places the company below its industry benchmark, indicating it is more carbon-efficient than most competitors.a
In 2025, Harmony Gold Mining ranked 7 out of 22 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Harmony Gold Mining is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Harmony Gold Mining reported a total carbon footprint of 5,482,478 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 4.32% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.a
The largest contributor to Harmony Gold Mining's total carbon footprint was Scope 2 emissions, accounting for 78.74% of the company's total carbon footprint, followed by Scope 3 emissions at 18.12%.a
