In 2023, NSA 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) and Scope 2 (indirect emissions from purchased energy).
However, NSA has not published a category-level breakdown of its Scope 3 emissions, limiting visibility into specific value chain sources.
| Metric (tCO2e) | 2023 | 2022 |
|---|---|---|
Total Scope 1 | 4,403a | 4,442a |
Total Scope 2 | ||
Unspecified Calculation Method | 31,971a | 32,056a |
Total Scope 3 | N/A | N/A |
Total Scope 1 Revenue Intensity (tCO2e/$M) | 5.1313a | 5.5416a |

In 2023, the total operational greenhouse gas (GHG) emissions of NSA amounted to 36,374 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 2022, the total operational greenhouse gas (GHG) emissions of NSA decreased by 0.34%, showing that the company has made progress in taking action to reduce the climate impact of its operations.a
In 2023, the total Scope 1 emissions of NSA were 4,403 metric tons of CO₂ equivalent (tCO₂e).a
Compared to the previous year (2022), NSA's Scope 1 emissions remained relatively stable, indicating that NSA's emissions have plateaued with no significant change in its operational footprint.a
In 2023, NSA reported Scope 2 greenhouse gas (GHG) emissions of 31,971 tCO₂e without specifying the calculation method.a
Compared to the previous year (2022), NSA's Scope 2 emissions (Unspecified Calculation Method) have remained relatively stable, indicating that NSA's emissions have plateaued with no significant change in its energy consumption footprint.a
In 2023, NSA reported its Scope 2 emissions using an unspecified methodology.a
In 2023, NSA reported Scope 1 greenhouse gas (GHG) emissions of 4,403 tCO₂e and total revenues of USD 858 millions. This translates into an emissions intensity of 5.13 tCO₂e per millions USD.a
In 2023, NSA reported a Scope 1 emissions intensity of 5.13 tCO₂e per millions USD. Compared to the peer group median of 1.33, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2023, NSA ranked 16 out of 22 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
NSA is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
