In 2025, JSE completed a corporate carbon footprint assessment and publicly disclosed its greenhouse gas (GHG) emissions according to the GHG Protocol, covering Scope 1 (direct emissions from owned or controlled sources), Scope 2 (indirect emissions from purchased energy) and Scope 3 (indirect emissions across the value chain).
However, JSE has not published a category-level breakdown of its Scope 3 emissions, limiting visibility into specific value chain sources.
| Metric (tCO2e) | 2025 | 2024 | 2023 | 2022-2019 |
|---|---|---|---|---|
Total Scope 1 | 40a | 205a | 948a | |
Total Scope 2 | ||||
Unspecified Calculation Method | 5,899a | 6,004a | 4,350a | |
Total Scope 3 | 2,494a | 2,830a | 2,288a | |
Total Scope 1 Revenue Intensity (tCO2e/$M) | 0.1871a | 1.2494a | 6.173a |

In 2025, the total operational greenhouse gas (GHG) emissions of JSE amounted to 5,939 metric tons of CO2 equivalent. This figure includes both direct emissions from owned or controlled sources (Scope 1) and indirect emissions from purchased energy (Scope 2).a
Compared to 2024, the total operational greenhouse gas (GHG) emissions of JSE decreased by 4.35%, showing that the company has made progress in taking action to reduce the climate impact of its operations.a
In 2025, the total Scope 1 emissions of JSE were 40 metric tons of CO₂ equivalent (tCO₂e).a
Since 2021, JSE's Scope 1 emissions have decreased by 48.05%, reflecting a declining long-term trend in Scope 1 emissions over time.a
Compared to the previous year (2024), JSE's Scope 1 emissions decreased by 80.49%, highlighting the company's efforts to lower direct emissions from assets it owns or controls.a
In 2025, JSE reported Scope 2 greenhouse gas (GHG) emissions of 5,899 tCO₂e without specifying the calculation method.a
Since 2021, JSE's Scope 2 greenhouse gas (GHG) emissions (Unspecified Calculation Method) have remained relatively stable, indicating that JSE's emissions have plateaued with no significant change in its energy consumption footprint.a
Compared to the previous year (2024), JSE's Scope 2 emissions (Unspecified Calculation Method) have remained relatively stable, indicating that JSE's emissions have plateaued with no significant change in its energy consumption footprint.a
In 2025, JSE reported its Scope 2 emissions using an unspecified methodology.a
In 2025, JSE reported 2,494 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 JSE includes a breakdown across 0 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, JSE reported total Scope 3 emissions of 2,494 metric tons of CO₂ equivalent (tCO₂e).a
Since 2021, JSE's Scope 3 emissions have increased by 109.05%, reflecting a rising long-term trend in Scope 3 emissions over time.a
Compared to the previous year (2024), JSE's Scope 3 emissions decreased by 11.87%, highlighting the company's efforts to lower indirect emissions from its value chain.a
In 2025, JSE reported Scope 1 greenhouse gas (GHG) emissions of 40 tCO₂e and total revenues of USD 214 millions. This translates into an emissions intensity of 0.19 tCO₂e per millions USD.a
In 2025, JSE reported a Scope 1 emissions intensity of 0.19 tCO₂e per millions USD. Compared to the peer group median of 0.16, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, JSE ranked 15 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
JSE is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, JSE reported a total carbon footprint of 8,433 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 6.7% decrease compared to 2024, indicating progress in reducing its overall greenhouse gas output.a
The largest contributor to JSE's total carbon footprint was Scope 2 emissions, accounting for 69.95% of the company's total carbon footprint, followed by Scope 3 emissions at 29.57%.a
