ISO 14064 GHG Validation and Verification

Earn credibility through carbon footprint verification.

ISO 14064 greenhouse gas (GHG) validation and verification helps organisations highlight their climate change and sustainability credentials.


A growing number of organisations are looking to voluntarily monitor and report GHG emissions and better manage their carbon footprint. ISO 14064 provides a framework for GHG accounting and verification to organisations looking to quantify and reduce GHG emissions.

Issued in three parts, each serves a unique intent:

  • Part 1 - Specifies principles and requirements at the organisation level for quantification and reporting of GHG emissions and removals. It covers design, development, management, reporting and verification of an organisation’s GHG inventory.
  • Part 2 - Supports multiple GHG project types, so must adequately address offset carbon credits and innovative technology projects, as well as internal projects. The second part specifies principles and requirements, and provides guidance at the project level for quantification, monitoring and reporting of activities intended to cause GHG emission reductions or removal enhancements. It covers GHG project planning; identifying and selecting GHG sources, sinks and reservoirs relevant to the project and baseline scenario; monitoring, quantifying, documenting and reporting GHG project performance; and managing data quality.
  • Part 3 - Specifies principles and requirements and guides those conducting or managing the validation and/or verification of GHG assertions. It can be applied to organisational or GHG project quantification, monitoring and reporting.

To future-proof the standard as far as possible, the ISO/TC 207/SC7 technical group continues to work closely with key bodies such as Carbon Disclosure Project (CDP), United Nations Framework Convention on Climate Change (UNFCCC), World Resources Institute (WRI), The Gold Standard Foundation and other key parties.

Benefits of ISO 14064

  • Showcase integrity

Verification against ISO 14064-1 and ISO 14064-2 highlights the veracity of your systems and processes to prove your GHG inventory, assertions and reports conform to the ISO 14064 standard; and are free from errors, omissions or misstatements.

  • Hit targets

Validation against ISO 14064-2, establishes the integrity of your project baseline, design plan and supporting assumptions to ensure you realise your projected GHG reductions.

  • Validate success

Verification against ISO 14064-1 provides the necessary assurance of your carbon footprint declarations. Validation of GHG projects to ISO 14064-2 provides confidence that the GHG project, if implemented as planned, will help achieve the projected emission reductions. Verification of your GHG projects gives assurance to your stakeholders of the quantum of emission reductions achieved in a specified period.
