Frequently asked questions

01 | ABOUT THE MYCELIUM NETWORK

  • We’re an open-access emissions database.

    We gather publicly available emissions information and centralise it into one machine-readable and openly accessible data pool for organisations’ carbon emissions.

  • Our goal is to drive decarbonisation by democratising access to emissions data.

    As a social enterprise, this mission is legally bound into the fabric of our company.

  • Yes, our database includes emissions data from companies worldwide, and we are continually expanding our coverage.

    If you don’t see data for your region, feel free to suggest companies or sources for inclusion.

02 | USING AND CONTRIBUTING DATA

  • Our data comes from publicly available sources such as company websites and national directories like Companies House in the UK.

    When you see the verified tick, it means the data has been provided by the company themselves, adding extra provenance to the data source.

  • Yes, absolutely! There is no charge to sign up and transparently disclose emissions.

  • Yes! If you spot emissions data that isn’t listed or notice incorrect data, you can notify us.

    Contributions from the community help keep our database robust and accurate. Contact us at crew@mycelium.global to share your findings.

  • Absolutely – this is at the heart of what we do. Our platform is designed to make it easy for businesses to claim their listings.

    To ensure authenticity, the sign-up email must match the URL associated with the company (e.g., b.gates@microsoft.com cannot claim Apple Inc’s listing).

  • Not all data is verified directly by us. However, when you see the verified tick, it indicates the data was directly provided by the company or confirmed through official channels.

    Unverified data can still be useful but should be interpreted with caution.

  • Updates depend on the availability of new public disclosures or company updates, but we aim to refresh listings regularly.

  • We strive for accuracy, but errors can occur. If you notice discrepancies, please reach out to us. We’ll review and update the information to maintain the integrity of the database.

  • Yes, we aim to include data from as many industries as possible. From energy and manufacturing to retail and services, our goal is to offer comprehensive coverage to drive cross-sector decarbonisation.

  • If you’re looking for data that isn’t currently listed, let us know at crew@mycelium.global. While we can’t guarantee immediate results, we’ll do our best to locate and include the data in our database.

03 | SCORING AND TRANSPARENCY

  • The Mycelium Score is a score out of 10 that reflects the carbon intensity of a company compared to its peers within the same sector.

    Up to 6.5 points are awarded for carbon intensity, and the remaining 3.5 points are based on the quality of the data provided, taking into account the use of third-party verification and whether the profile is verified.

  • The score considers factors such as direct and indirect emissions, normalised against revenue. This ensures fair comparisons while highlighting leaders in decarbonisation.

    For a deeper dive into our methodology, check out our white paper on Mycelium’s carbon scoring.

  • The Transparency Score evaluates how openly an organisation discloses its emissions data to Mycelium. It is calculated based on the percentage of emissions categories reported.


    Not all categories carry equal weight; the weighting reflects emissions averages for the organisation’s industry. For example, in financial services, up to 98% of emissions may fall within the investment category, making it heavily weighted. If a company reports all other categories except investments, it will receive a low score.

    Conversely, reporting the most crucial and highly emitting categories, including investments, will result in a much higher Transparency Score.

04 | API AND COMMERCIAL USE

  • Yes, we do. The API is pro bono for academics and charitable organisations. For commercial applications, there is a subscription fee.

    Drop us a line at api@mycelium.global for more information.

  • That’s great, we’d be happy to help. We can provide data in CSV format or via our API.

    Drop us a line at api@mycelium.global to get started.

05 | PARTNERSHIS AND SUPPORT

  • That’s fantastic – we would love to talk to you!

    We work with carbon accountants so they can disclose data onto the Mycelium Network on behalf of their clients. This provides the best scoring metrics on our platform and highlights your clients’ efforts in the best light.

    Simply contact us at crew@mycelium.global to begin the process.

  • By providing access to peer comparisons and highlighting best practices, we help organisations benchmark their carbon emissions and improve transparency.

    Sharing your emissions data on Mycelium can also enhance your reputation and attract sustainability-conscious stakeholders.

    The network helps users identify the best-performing low-carbon actors in any sector, enabling businesses to decarbonise their supply chains.
