FAQ's Frequently Asked Questions

Q: Does CDP require third-party verification of emissions data?

Verification isn't required simply to disclose to CDP, but it is a mandatory essential criterion for a Leadership-level (A or A-) score. For 2026, A-List status specifically requires 100% third-party verification of Scope 1 and Scope 2 emissions, plus at least 70% of one reported Scope 3 category. Carbonology® verifies GHG data to ISO 14064-3 under our UKAS-accredited scope, giving you assurance that meets CDP's requirement.

Q: What CDP score level requires third-party verified emissions?

Third-party verification becomes an essential criterion at Leadership level (A/A-) under CDP's 2026 scoring methodology. Below Leadership, verification remains optional but still strengthens your score on CDP's data-quality criteria. We provide a free assessment to establish what level of verification your target score needs.

Q: Does an ESRS-compliant verification report satisfy CDP's assurance requirement?

Yes. From 2026, CDP accepts verification carried out under ESRS-approved standards as valid third-party assurance for Leadership scoring, provided Scope 1, Scope 2, and at least one Scope 3 category sit within the audit scope. Carbonology verification statements, issued under ISO 14064-3, are recognised as meeting this requirement — useful if you're already verifying for CSRD.

Q: What's the difference between CDP disclosure and CDP verification?

Disclosure is submitting your CDP questionnaire response; verification is an independent third party confirming that your reported emissions data is materially accurate. You can disclose without verification, but a Leadership (A/A-) score requires it for Scope 1 and 2, and A-List status requires it for Scope 3 too. Carbonologist®-led verification gives you a defensible statement to sit alongside your submission.

Q: How long does CDP-ready GHG verification take?

A Scope 1 and 2 verification typically takes 4-6 weeks from data submission to verification statement, with Scope 3 usually taking longer due to supply-chain data dependencies. We recommend starting at least 8-10 weeks before your CDP submission deadline to leave time for any data queries. Get in touch for a free assessment of your timeline.
