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.

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. Bkw AG's score sits at the top of this page and in the score panel.

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. 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. Companies with nothing to model are graded on how much of their industry's typical footprint the reported categories cover.

For Bkw AG, the single biggest gap is Downstream leased assets (Scope 3 Category 13). Mycelium estimates it accounts for around 13% 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.

In total, roughly 13% of Bkw AG's estimated emissions sit in categories it hasn't reported. Disclosing these would be the fastest way to raise the transparency score.

Bkw AG carbon emissions FAQs

What are Bkw AG's carbon emissions?

In its 2025 reporting year, Bkw AG disclosed total emissions of 1,367,700 tCO2e across all scopes. Including Mycelium estimates for undisclosed categories, the adjusted total is 1,615,823 tCO2e. Scope 1 accounted for the largest share, around 53% of the total.

Does Bkw AG report Scope 1, Scope 2 and Scope 3 emissions?

For 2025, Bkw AG's available disclosure covers Scope 1 (858,100 tCO2e), Scope 2 (2,700 tCO2e), Scope 3 across 12 of the 15 GHG Protocol categories. Figures not reported by the company are shown as modelled estimates and labelled as such.

How transparent is Bkw AG's emissions reporting?

Bkw AG has a Mycelium transparency score of 84.6 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 Bkw AG sustainable?

Mycelium measures sustainability through carbon emissions data rather than giving a yes or no verdict. Bkw AG has a Mycelium Score of 7.5 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 Bkw AG environmentally friendly?

Carbon emissions are one measurable part of environmental impact, and the part Mycelium tracks. Bkw AG disclosed 1,367,700 tCO2e for 2025, and its Mycelium Score of 7.5 out of 10 shows how that performance compares with similar companies in its sector.
