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. JERA'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.

JERA 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.

JERA carbon emissions FAQs

What are JERA's carbon emissions?

In its 2023 reporting year, JERA disclosed total emissions of 147,157,513 tCO2e across all scopes. Scope 1 accounted for the largest share, around 77% of the total.

Does JERA report Scope 1, Scope 2 and Scope 3 emissions?

For 2023, JERA's available disclosure covers Scope 1 (113,756,000 tCO2e), Scope 2 (70,000 tCO2e), Scope 3 across 8 of the 15 GHG Protocol categories. Figures not reported by the company are shown as modelled estimates and labelled as such.

How transparent is JERA's emissions reporting?

JERA has a Mycelium transparency score of 94.7 out of 100. The score weights each emissions category by how material it is for the company's industry, so it reflects whether the disclosures that matter most have been made.

Is JERA sustainable?

Mycelium measures sustainability through carbon emissions data rather than giving a yes or no verdict. JERA has a Mycelium Score of 1.2 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 JERA environmentally friendly?

Carbon emissions are one measurable part of environmental impact, and the part Mycelium tracks. JERA disclosed 147,157,513 tCO2e for 2023, and its Mycelium Score of 1.2 out of 10 shows how that performance compares with similar companies in its sector.
