National Storage REIT reported 28% of the adjusted total. Mycelium estimated the remaining 72% for the categories it did not disclose. National Storage REIT reported a Scope 3 total of 19,306 tCO₂e but did not break it down into the 15 categories. The model of the categories it did not report comes to more than that, so the adjusted total counts the model, with the reported figure inside it.

Which figure should I use?
Estimating your own supply-chain emissions from spend with this company? Use Upstream Modelled. The GHG Protocol defines purchased-goods emissions as cradle-to-gate, which means this company's own operations plus its upstream supply chain. Any of those emissions the company has not disclosed are filled with modelled estimates, so a transparent company is not unfairly penalised against one that simply has not reported.
Looking at what the company filed itself? Use the Reported column. Total Reported also includes downstream emissions, such as the lifetime use of the products this company sells, which the GHG Protocol attributes to the users of those products rather than to customers buying goods and services.
Reported counts only emissions the company has filed itself. A blank or low Reported cell does not mean those emissions do not exist, just that the company has not disclosed them. When Upstream Reported sits close to Upstream Modelled, that is a positive signal: the company has disclosed most of its upstream emissions.

Snapshot
Based on reported data, retrieved with AI
- National Storage REIT reported 27,680 tCO₂e in 2025.
- Scope 3 accounted for 70% of reported emissions.
- Scope 2 reported under the location based methodology.
According to available emissions disclosures, National Storage REIT reported total yearly emissions of 27,680 tCO₂e in 2025. Scope 3 emissions accounted for 70% of the reported footprint, indicating supply chain activity, purchased goods and services, business travel, and wider operational dependencies were the most significant contributors to the company's carbon footprint.
The company achieved a Mycelium Score of 1.3, placing it well below average for its sector for sustainability performance, and received a transparency score of 22.5, pointing to very little public detail on their key emissions.

National Storage REIT reported a Scope 3 total of 19,306 tCO₂e but did not break it down into the 15 categories. Mycelium's model of the categories it did not report comes to more than that, so the estimates below replace it in the adjusted total, with the reported figure counted inside them.

The company's own Scope 3 total is reported, it was simply filed as a single figure with no category split. A cell marked “ESTIMATED” is a figure the company did not disclose, modelled by Mycelium. Cells marked “–” were not disclosed and could not be modelled.

How scoring works
How the Mycelium Score is calculated
The Mycelium Score is out of 10. Up to 6.5 points reflect carbon intensity vs peers in the same NACE section (emissions normalised against revenue, log-scaled between the 5th and 95th percentile of each company's latest reporting year in that section; a section needs at least 5 companies to be benchmarked). The band above 6.5 is earned through verified data quality on a claimed profile: declaring every reporting category yourself (up to 2.0), preparation by a carbon accountant (2.0) and independently audited figures (2.0). The total is multiplied by the transparency score and capped at 10. A disclosure with an implausibly large figure (Scope 1 or 2 over 300 million tonnes, a Scope 3 figure over 2 billion tonnes or a total over 2.5 billion tonnes) is not scored until it has been checked.
A higher score means lower carbon intensity than sector peers, backed by data that's third-party verified, claimed by the company, and fully disclosed. National Storage REIT's score sits at the top of this page and in the score panel. Without a revenue figure to measure carbon intensity, or an industry classification to compare it within, a company has no score.
How the Transparency Score is calculated
The Transparency Score is the share of a company's estimated footprint that it reported itself, graded from A (very high) down to F (very low). Where a category is missing, Mycelium models what it would hold for a company of that size and industry and counts it as undisclosed, so an unreported category where the bulk of emissions sit hurts far more than a minor one. Unreported downstream categories (9 to 15) count at a quarter of their modelled size in this share; the carbon intensity behind the score still counts them in full. A Scope 3 total filed without a category breakdown earns very little credit for the part left unattributed, because it does not show which categories are inside it: a company can count business travel, leave purchased goods out entirely, and the total looks the same. Without a revenue figure the footprint cannot be modelled, so the company has no Transparency Score.
For National Storage REIT, the single biggest gap is Use of sold products (Scope 3 Category 11). Mycelium estimates it accounts for around 45% of the company's estimated footprint, yet it hasn't been disclosed. Leaving a bucket this large unreported is what's holding the transparency score down.
Other material categories National Storage REIT hasn't disclosed:
- Downstream leased assets (Scope 3 Category 13), around 21% of the estimated footprint
- Capital goods (Scope 3 Category 2), around 11% of the estimated footprint
- Purchased goods & services (Scope 3 Category 1), around 5% of the estimated footprint
In total, roughly 92% of National Storage REIT's estimated emissions sit in categories it hasn't reported. Disclosing these would be the fastest way to raise the transparency score.

National Storage REIT carbon emissions FAQs
What are National Storage REIT's carbon emissions?
In its 2025 reporting year, National Storage REIT disclosed total emissions of 27,680 tCO2e across all scopes. Including Mycelium estimates for undisclosed categories, the adjusted total is 99,483 tCO2e. Scope 3 accounted for the largest share of the reported total, around 70%.
Does National Storage REIT report Scope 1, Scope 2 and Scope 3 emissions?
For 2025, National Storage REIT's available disclosure covers Scope 1 (484 tCO2e), Scope 2 (7,890 tCO2e) and a Scope 3 total of 19,306 tCO2e without a category breakdown. Figures not reported by the company are shown as modelled estimates and labelled as such.
How transparent is National Storage REIT's emissions reporting?
National Storage REIT has a Mycelium transparency score of 22.5 out of 100. The score is the share of the company's estimated footprint that it reported itself, so an undisclosed category where most of its emissions sit weighs far more than a minor one.
Is National Storage REIT sustainable?
Mycelium measures sustainability through carbon emissions data rather than giving a yes or no verdict. National Storage REIT has a Mycelium Score of 1.3 out of 10, which reflects its emissions intensity against sector peers together with how transparent and well-verified its reporting is. The emissions figures and disclosure documents on this page give the fuller picture.
Is National Storage REIT environmentally friendly?
Carbon emissions are one measurable part of environmental impact, and the part Mycelium tracks. National Storage REIT disclosed 27,680 tCO2e for 2025, and its Mycelium Score of 1.3 out of 10 shows how that performance compares with similar companies in its sector.
