As climate change and sustainability reporting move to the forefront of business strategy, ISO sustainability standards such as ISO 14064 make credible greenhouse gas (GHG) management more important than ever. ISO 14064 provides the internationally recognised framework that organisations use to measure, report, and verify their GHG emissions with consistency and integrity.
ISO 14064 is a family of international standards that guide organisations in measuring, quantifying, monitoring, reporting and verifying greenhouse gas emissions and removals. Developed by the International Organization for Standardization (ISO), these standards help companies build clear and credible carbon inventories that support both regulatory compliance and voluntary climate commitments.
Where the GHG Protocol provides detailed accounting guidance, ISO 14064 places greater emphasis on reporting requirements and independent verification. Used together, they give organisations a solid framework for structuring emissions data and obtaining third‑party assurance, making carbon reporting more transparent and trustworthy.
The ISO 14064 framework is divided into three distinct parts:
Each part complements the others, creating a comprehensive system for managing and disclosing carbon footprints.
Achieving ISO 14064 certification offers substantial advantages:
While both ISO 14064 and the GHG Protocol aim to support carbon accounting, they serve different functions. The GHG Protocol is commonly used to calculate and organise emissions data, providing detailed measurement and accounting guidance. ISO 14064 places greater emphasis on reporting requirements and independent verification, giving organisations a structured way to turn internal data into externally assured disclosures.
ISO 14064 | GHG Protocol |
Focus on verification and reporting | Focus on measurement and accounting guidance |
Supports certification through audits | Framework for internal carbon accounting |
Used globally for third-party validated disclosures | Basis for many sustainability reports (e.g., CDP) |
In practice, many organisations use the GHG Protocol to measure emissions internally, then apply ISO 14064 standards for external reporting and assurance.
Achieving ISO 14064 certification typically involves:
Proactive preparation — particularly around data collection and documentation — makes the certification process smoother.
💡 Challenge: Collecting comprehensive and high-quality activity data.
✅ Solution: Implement robust data management systems early.
💡 Challenge: Allocating internal resources and expertise.
✅ Solution: Train key staff or engage experienced consultants.
💡 Challenge: Understanding boundaries and scopes.
✅ Solution: Carefully define organisational and operational boundaries upfront.
A phased approach and strong project governance can help organisations overcome these hurdles.
ISO 14064-1 covers emissions at an organisational level. ISO 14064-2 applies to projects designed to reduce or remove emissions, while ISO 14064-3 explains how reported information should be validated and verified.
ISO 14064 focuses on how greenhouse gas emissions are reported and independently verified, while the GHG Protocol provides the accounting rules used to calculate and organise those emissions. Many organisations use the GHG Protocol for internal carbon accounting and ISO 14064 for external reporting and third‑party assurance.
Yes. Many organisations use the GHG Protocol to structure emissions accounting and ISO 14064 for independent verification and certification.
Currently, ISO 14064 is voluntary, although certain industries and government programmes encourage or require verified GHG disclosures.
The organisation first prepares its greenhouse gas inventory and checks the supporting information. An independent verification body then reviews the figures and the methods used to determine whether the emissions statement is reliable.
The timeframe depends on the size of the organisation and the quality of its available data. In many cases, the process may take around three to six months, with larger or more complex inventories requiring more time. Good preparation and clear supporting information can help the verification run more smoothly.
The framework can make carbon reporting more credible and help organisations identify areas where emissions could be reduced. Verified information may also strengthen sustainability disclosures and support progress towards net zero targets.
ISO 14064 helps build trust in carbon reporting by turning emissions data into a structured, verifiable disclosure rather than just high‑level claims. When organisations align their greenhouse gas inventories with ISO 14064 and obtain independent verification, they strengthen transparency, prepare for future regulatory requirements and position themselves as leaders in responsible, data‑driven sustainability.
