Which figure should I use?

Use Modelled. It is the most complete view: any categories the company hasn't disclosed are filled with industry-typical estimates, so a transparent company isn't unfairly penalised against one that simply hasn't reported.

Reported counts only emissions the company has filed itself. A blank or low Reported cell doesn't mean those emissions don't exist, just that the company hasn't disclosed them.

When Reported sits close to Modelled, that is a positive signal. The company has disclosed most of its salient emissions and there's little gap for the model to fill. Even then, Modelled is the right figure to use for a like-for-like comparison across companies.

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). The remaining 3.5 reflect data quality: third-party verified, profile claimed by the company, and full disclosure across all reporting categories.

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. Imperial Brands PLC'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 Imperial Brands PLC, the single biggest gap is Downstream transportation & distribution (Scope 3 Category 9). Mycelium estimates it accounts for around 16% of the company's total footprint, typically the largest source of emissions for a Services company, yet it hasn't been disclosed. Leaving a bucket this large unreported is what's holding the transparency score down.

Other material categories Imperial Brands PLC hasn't disclosed:

  • Use of sold products (Scope 3 Category 11), around 16% of the estimated footprint
  • Upstream transportation & distribution (Scope 3 Category 4), around 14% of the estimated footprint
  • Processing of sold products (Scope 3 Category 10), around 12% of the estimated footprint

In total, roughly 88% of Imperial Brands PLC's estimated emissions sit in categories it hasn't reported. Disclosing these would be the fastest way to raise the transparency score.
