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.
Sustainability
Snapshot
Based on reported data, retrieved with AI
- ACI reported 201,958 tCO₂e in 2025.
- Scope 3 accounted for 53% of emissions.
According to available emissions disclosures, ACI reported total yearly emissions of 201,958 tCO₂e in 2025. Scope 3 emissions accounted for 53% 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 1.0, placing it well below average for its sector for sustainability performance, and received a transparency score of 24.0, pointing to very little public detail on their key 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). 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. ACI'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 ACI, the single biggest gap is Purchased goods & services (Scope 3 Category 1). Mycelium estimates it accounts for around 30% 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 ACI hasn't disclosed:
- Use of sold products (Scope 3 Category 11), around 10% of the estimated footprint
- End-of-life treatment of sold products (Scope 3 Category 12), around 4% of the estimated footprint
In total, roughly 44% of ACI's estimated emissions sit in categories it hasn't reported. Disclosing these would be the fastest way to raise the transparency score.

ACI carbon emissions FAQs
What are ACI's carbon emissions?
In its 2025 reporting year, ACI disclosed total emissions of 201,958 tCO2e across all scopes. Scope 3 accounted for the largest share, around 53% of the total.
Does ACI report Scope 1, Scope 2 and Scope 3 emissions?
For 2025, ACI's available disclosure covers Scope 1 (75,632 tCO2e), Scope 2 (19,850 tCO2e). Figures not reported by the company are shown as modelled estimates and labelled as such.
How transparent is ACI's emissions reporting?
ACI has a Mycelium transparency score of 24 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 ACI sustainable?
Mycelium measures sustainability through carbon emissions data rather than giving a yes or no verdict. ACI has a Mycelium Score of 1 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 ACI environmentally friendly?
Carbon emissions are one measurable part of environmental impact, and the part Mycelium tracks. ACI disclosed 201,958 tCO2e for 2025, and its Mycelium Score of 1 out of 10 shows how that performance compares with similar companies in its sector.
