Which figure should I use?
Comparing companies? Use Total Modelled. It is the most complete like-for-like view: any categories the company has not disclosed are filled with industry-typical estimates, so a transparent company is not unfairly penalised against one that simply has not reported.
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. The Total figure 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 Reported sits close to Modelled, that is a positive signal: the company has disclosed most of its salient emissions.
Sustainability
Snapshot
Based on reported data, retrieved with AI
- Gasunie reported 1,046,225 tCO₂e in 2025.
- Scope 3 accounted for 74% of emissions.
- Total emissions increased 18.5% from 2024.
- Disclosures available for 2 reporting years (since 2024).
- Scope 2 reported under the location based methodology.
According to available emissions disclosures, Gasunie reported total yearly emissions of 1,046,225 tCO₂e in 2025. Scope 3 emissions accounted for 74% of reported output, 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 3.3, placing it below average for its sector for sustainability performance, and received a transparency score of 51.0, pointing to fairly limited disclosure, with notable gaps in key areas.

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 sector peers (emissions normalised against revenue), scaled by how transparent the reporting is. 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), capped at 10.
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. Gasunie's score sits at the top of this page and in the score panel.
How the Transparency Score is calculated
The Transparency Score measures how much of a company's key emissions data is publicly disclosed, graded from A (very high) down to F (very low). Crucially, it weights each gap by how material that bucket is for the company's industry, so an undisclosed category where the bulk of emissions sit hurts far more than a minor one.
For Gasunie, the single biggest gap is Use of sold products (Scope 3 Category 11). Mycelium estimates it accounts for around 45% of the company's total footprint, typically the largest source of emissions for a Power Generation company, yet it hasn't been disclosed. Leaving a bucket this large unreported is what's holding the transparency score down.
Other material categories Gasunie hasn't disclosed:
- Capital goods (Scope 3 Category 2), around 12% of the estimated footprint
- Purchased goods & services (Scope 3 Category 1), around 9% of the estimated footprint
- Fuel & energy related activities (Scope 3 Category 3), around 5% of the estimated footprint
In total, roughly 71% of Gasunie's estimated emissions sit in categories it hasn't reported. Disclosing these would be the fastest way to raise the transparency score.

Gasunie carbon emissions FAQs
What are Gasunie's carbon emissions?
In its 2025 reporting year, Gasunie disclosed total emissions of 1,046,225 tCO2e across all scopes. Scope 3 accounted for the largest share, around 74% of the total.
Does Gasunie report Scope 1, Scope 2 and Scope 3 emissions?
For 2025, Gasunie's available disclosure covers Scope 1 (183,700 tCO2e), Scope 2 (92,700 tCO2e). Figures not reported by the company are shown as modelled estimates and labelled as such.
How transparent is Gasunie's emissions reporting?
Gasunie has a Mycelium transparency score of 51 out of 100. The score weights each emissions category by how material it is for the company's industry, so it reflects whether the disclosures that matter most have been made.
Is Gasunie sustainable?
Mycelium measures sustainability through carbon emissions data rather than giving a yes or no verdict. Gasunie has a Mycelium Score of 3.3 out of 10, which reflects its emissions intensity against sector peers together with how transparent and well-verified its reporting is. The emissions figures, disclosure documents and climate targets on this page give the fuller picture.
Is Gasunie environmentally friendly?
Carbon emissions are one measurable part of environmental impact, and the part Mycelium tracks. Gasunie disclosed 1,046,225 tCO2e for 2025, and its Mycelium Score of 3.3 out of 10 shows how that performance compares with similar companies in its sector.
