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.

Snapshot
Based on reported data, retrieved with AI
- JSR Micro reported 27,363 tCO₂e in 2025.
- Scope 3 accounted for 96% of emissions.
- Reported across 8 of 15 GHG Protocol Scope 3 categories.
- Scope 2 reported under the market based methodology.
According to available emissions disclosures, JSR Micro reported total yearly emissions of 27,363 tCO₂e in 2025. Scope 3 emissions accounted for 96% of reported output, indicating supply chain activity, purchased goods and services, business travel, and wider operational dependencies were the most significant contributors to the company's carbon footprint.
The company achieved a Mycelium Score of 4.7, placing it mid-pack within its sector for sustainability performance, and received a transparency score of 72.4, meaning they share a fair amount, though with some gaps along the way.

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. JSR Micro'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 JSR Micro, the single biggest gap is Use of sold products (Scope 3 Category 11). Mycelium estimates it accounts for around 24% of the company's total footprint, typically the largest source of emissions for a Materials company, yet it hasn't been disclosed. Leaving a bucket this large unreported is what's holding the transparency score down.
Other material categories JSR Micro hasn't disclosed:
- End-of-life treatment of sold products (Scope 3 Category 12), around 11% of the estimated footprint
- Processing of sold products (Scope 3 Category 10), around 5% of the estimated footprint
- Fuel & energy related activities (Scope 3 Category 3), around 3% of the estimated footprint
In total, roughly 43% of JSR Micro's estimated emissions sit in categories it hasn't reported. Disclosing these would be the fastest way to raise the transparency score.

How transparent is JSR Micro's emissions reporting?
JSR Micro has a Mycelium transparency score of 72.4 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 JSR Micro sustainable?
Mycelium measures sustainability through carbon emissions data rather than giving a yes or no verdict. JSR Micro has a Mycelium Score of 4.7 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 JSR Micro environmentally friendly?
Carbon emissions are one measurable part of environmental impact, and the part Mycelium tracks. JSR Micro disclosed 27,363 tCO2e for 2025, and its Mycelium Score of 4.7 out of 10 shows how that performance compares with similar companies in its sector.
