Power Generation Carbon Emissions Data

Power generators report some of the largest Scope 1 figures in any sector, driven directly by their fuel mix. Generation portfolios differ enormously, so emissions intensity and the direction of travel year on year say far more than absolute totals.

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 188 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.

Power Generation carbon emissions FAQs

What are Power Generation carbon emissions?

Power Generation carbon emissions are the greenhouse gases produced by companies in this sector, reported as Scope 1 (direct operations), Scope 2 (purchased energy) and Scope 3 (the wider value chain). Mycelium brings the sector's public disclosures together so they can be searched and compared in one place.

Can I compare Power Generation companies by carbon emissions?

Yes. Mycelium ranks Power Generation companies by Mycelium Score, which reflects emissions intensity within the sector alongside transparency and verification, and each profile shows reported figures, disclosure documents and climate targets. Mycelium currently tracks 188 companies in this sector.

Where does this Power Generation emissions data come from?

The data comes from publicly available company disclosures such as sustainability reports and annual reports, combined with modelled estimates where reporting is incomplete. Modelled values are always labelled. See our methodology and data sources for the full picture.
