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. HMM Co., Ltd.'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 HMM Co., Ltd., the single biggest gap is Downstream transportation & distribution (Scope 3 Category 9). Mycelium estimates it accounts for around 4% of the company's total footprint, typically the largest source of emissions for a Transportation Services company, yet it hasn't been disclosed. Leaving a bucket this large unreported is what's holding the transparency score down.

In total, roughly 4% of HMM Co., Ltd.'s estimated emissions sit in categories it hasn't reported. Disclosing these would be the fastest way to raise the transparency score.
