Terms of Use

Carbonbench is an open protocol that compiles public corporate carbon reports via machine reading, checks them with deterministic rules, and cryptographically seals every record. The service is provided "as is" and "as available". We do not guarantee uninterrupted availability, error-free operation, or fitness for a particular purpose.

Every number, formula, and label we publish is tied to a public methodology (see Methodology) — there is no black box. But this does not mean the results are error-free — we also publish our own margin of error (see Legal Notice).

The Accuracy Estimate, Transparency Score, Target Quality, and all similar indicators are the output of the statistical plausibility analysis — not an audit opinion, an assurance opinion, or a credit rating. A score being high or low does not constitute a recommendation on whether to invest in, extend credit to, or make any commercial decision regarding the company in question.

The scores, tables, charts, protocol, and methodology descriptions on the site — commercial or not — may be shared, embedded, and distributed freely; you do not need our permission. The content is licensed under Creative Commons Attribution–NoDerivatives 4.0 (CC BY-ND 4.0). Two conditions apply:

• Attribution and link required: credit the source as "Carbonbench" wherever you use it, and link to the relevant page (e.g., "Source: Carbonbench, carbonbench.org/universe.html?r=…").
• No derivatives: you may copy and redistribute text and scores verbatim, but you may not modify, adapt, or present them differently from how they are published. Tilting a score in your favor, adjusting the decimal/threshold, or presenting it as a different number violates the license.

Presenting a record or score in isolation, stripped of its context (band, evidence status, "n/a"/"no disclosure" labels), as if it were a claim of certainty, also violates this condition. If you are not sure how to use it, you can ask us.

The platform is open. Single records and the static shard files are open without an account. The full list with scores (/gated/) requires sign-in and is not yet generally available — write to us for access. There is no API key and no enforced rate limit today; please keep your request rate reasonable and cache on your side. For programmatic access, use the Open API. Fair use:

• Do not send bulk requests dense enough to lock up the server; download a file once and cache it.
• Use the API in accordance with robots/access rules.
• When republishing, comply with the attribution-and-link and no-modification requirements.

Access that exceeds fair use, or is intended for scraping, may be limited or blocked by us.

Carbonbench and its related persons cannot be held liable for any direct or indirect damage arising from any commercial, financial, or legal decision made based on the information on the site. Data is compiled from publicly available sources; errors, omissions, or misleading statements in the source document are beyond our control. When we detect our own reading errors, we correct them and publish the record as a new version (records are not deleted).

We reserve the right to change these terms, the site, the API, and the scoring formulas without prior notice. Changes to scoring formulas take effect in two windows per year (January and July) and are published with a version number on the Methodology page — past versions are never lost.

Disputes arising from these terms are governed by the laws of the Republic of Türkiye. For your questions: support@carbonbench.org.
