Compare carbon emissions across Power Generation companies
The table ranks Power Generation companies by Mycelium Score, which rewards low emissions intensity within the sector, transparent reporting and third-party verification, rather than by raw totals, which would penalise the companies that report most completely. Mycelium tracks 204 companies in this sector; the top 25 are shown here.

Why power generation emissions data matters
Company-level carbon data in this sector is used by procurement teams reviewing suppliers, investors assessing climate risk, and sustainability teams building Scope 3 inventories. Access to comparable, sourced disclosures makes those decisions evidence-based rather than survey-based.
Carbon emissions data methodology
Mycelium combines public company disclosures with clearly labelled modelled estimates so companies can be compared on a like for like basis. Data availability varies by company, reporting year and disclosure type. Read our methodology, data sources and glossary for the detail.
