Scope 2 in these factors uses the company's market based figure.
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.

tCO2e5 values were derived via Mycelium's normalisation process rather than reported by the company. Cells marked “–” were not disclosed.
Cells marked “N/A” are categories the company declared not applicable in its report, so they count as disclosed with zero 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. Tesco 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.
Tesco PLC has disclosed the emissions categories that are material for its industry, so there's no single bucket dragging the transparency score down. The breakdown above shows full coverage across the categories that matter most for this kind of company.
