ISO 14064 Greenhouse gas (GHG) Accounting and Verification

What is ISO 14064?

The ISO 14064 standard series provides a globally recognised framework for measuring, reporting, and verifying greenhouse gas (GHG) emissions and reductions. Whether you are calculating your corporate carbon footprint, running emission reduction projects, or seeking third-party verification, ISO 14064 ensures your climate reporting is consistent, accurate, and trusted worldwide.

ISO 14064-1: Organisational-Level GHG Accounting & Reporting

01

Measure GHG Emissions

Quantify your full greenhouse gas impact by measuring direct emissions (Scope 1) from your operations and indirect emissions (Scope 2 and 3) from energy use and your supply chain.

02

Ensure Accuracy

Apply consistent, recognised methodologies to provide transparent, credible and auditable GHG reporting.

03

Meet Goals

Support corporate sustainability objectives, regulatory compliance and investor expectations with actionable insights.

04

Align with Frameworks

Ensure your reporting follows global standards such as the GHG Protocol and CDP for consistency, credibility and comparability.

ISO 14064-3: Verification & Validation

Organisations’ Carbon (GHG) Footprints can become verified under ISO 14064 by working with a recognised certification body.

  • Independent Verification: Provide objective verification of your GHG reports prepared under ISO 14064‑1 or ‑2 standards
  • Data Accuracy: Ensure your emissions data is complete, consistent and reliable for internal and external reporting.
  • Compliance Support: Assist with regulatory compliance, investor reporting and broader climate disclosure requirements.
  • Global Standards: Verification is conducted according to internationally recognised standards for credibility and assurance.

Frequently Asked Questions

Can my company be certified in ISO 14064?

No — organisations cannot be certified to ISO 14064-1 or 14064-2, because these are reporting and accounting standards. Instead, your GHG inventory or project report can be independently verified by a third party in accordance with ISO 14064-3. After verification, you’ll receive a statement or assurance report you can share with stakeholders.

Is ISO 14064 the same as the GHG Protocol?

Both provide standards for GHG accounting, and many organisations use them together. ISO 14064 is often preferred for international recognition and third-party verification, whereas the GHG Protocol is widely used as a framework for disclosure platforms such as CDP or SBTi.

They have recently announced a partnership to collaborate in the development of a co-branded corporate suite of GHG standards.

Can you verify my Carbon (GHG) Footprint?

Yes. We will calculate and verify your Carbon (GHG) Footprint, providing you with a logo and a certificate to demonstrate that True Solutions has assessed and verified the footprint.

However, if you wish for your footprint to be ISO 14064 certified, it must be verified by an external certification body.

What’s the difference between ISO 14064-1, 14064-2, and 14064-3?

  • 14064-1 → Organisational-level reporting (your company’s total carbon footprint).
  • 14064-2 → Project-level reporting (GHG reduction or removal projects).
  • 14064-3 → Independent verification and validation of -1 and -2 reports.

Together, they form a complete system: measure → report → verify.

How long does it take to become ISO 14064 verified for my Organisation's Carbon Footprint (GHG)?

A full Carbon (GHG) Footprint can typically be calculated in around 6-12 weeks, depending on the business size and data readiness. External verification by a recognised certification body will then be required to achieve ISO 14064 verification, which can take a further 6-12 weeks.
