Mills & Reeve LLP reported 9% of the adjusted total. Mycelium estimated the remaining 91% for the categories it did not disclose. Mills & Reeve LLP reported a Scope 3 total of 1,618 tCO₂e but did not break it down into the 15 categories. The model of the categories it did not report comes to more than that, so the adjusted total counts the model, with the reported figure inside it.

Mills & Reeve LLP reported a Scope 3 total of 1,618 tCO₂e but did not break it down into the 15 categories. Mycelium's model of the categories it did not report comes to more than that, so the estimates below replace it in the adjusted total, with the reported figure counted inside them. The reported figure is not discarded, and you can see it in the downloads below.

14 values were derived via Mycelium's normalisation process rather than reported by the company. The company's own Scope 3 total is reported, it was simply filed as a single figure with no category split. A cell marked “ESTIMATED” is a figure the company did not disclose, modelled by Mycelium. Cells marked “–” were not disclosed and could not be modelled.

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 peers in the same NACE section (emissions normalised against revenue, log-scaled between the 5th and 95th percentile of each company's latest reporting year in that section; a section needs at least 5 companies to be benchmarked). 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). The total is multiplied by the transparency score and capped at 10. A disclosure with an implausibly large figure (Scope 1 or 2 over 300 million tonnes, a Scope 3 figure over 2 billion tonnes or a total over 2.5 billion tonnes) is not scored until it has been checked.

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. Mills & Reeve LLP's score sits at the top of this page and in the score panel. Without a revenue figure to measure carbon intensity, or an industry classification to compare it within, a company has no score.

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. Unreported downstream categories (9 to 15) count at a quarter of their modelled size in this share; the carbon intensity behind the score still counts them in full. 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. Without a revenue figure the footprint cannot be modelled, so the company has no Transparency Score.

For Mills & Reeve LLP, the single biggest gap is Use of sold products (Scope 3 Category 11). Mycelium estimates it accounts for around 26% of the company's estimated footprint, yet it hasn't been disclosed. Leaving a bucket this large unreported is what's holding the transparency score down.

Other material categories Mills & Reeve LLP hasn't disclosed:

  • Purchased goods & services (Scope 3 Category 1), around 24% of the estimated footprint
  • Processing of sold products (Scope 3 Category 10), around 22% of the estimated footprint
  • Investments (Scope 3 Category 15), around 12% of the estimated footprint

In total, roughly 99% of Mills & Reeve LLP's estimated emissions sit in categories it hasn't reported. Disclosing these would be the fastest way to raise the transparency score.

Does Mills & Reeve LLP report Scope 1, Scope 2 and Scope 3 emissions?

For 2025, Mills & Reeve LLP's available disclosure covers Scope 1 (141 tCO2e), Scope 2 (0 tCO2e) and a Scope 3 total of 1,618 tCO2e without a category breakdown. Figures not reported by the company are shown as modelled estimates and labelled as such.

How transparent is Mills & Reeve LLP's emissions reporting?

Mills & Reeve LLP has a Mycelium transparency score of 3.1 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 Mills & Reeve LLP sustainable?

Mycelium measures sustainability through carbon emissions data rather than giving a yes or no verdict. Mills & Reeve LLP has a Mycelium Score of 0.2 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 Mills & Reeve LLP environmentally friendly?

Carbon emissions are one measurable part of environmental impact, and the part Mycelium tracks. Mills & Reeve LLP disclosed 1,759 tCO2e for 2025, and its Mycelium Score of 0.2 out of 10 shows how that performance compares with similar companies in its sector.
