Greenhouse gas explaining the Standard

Standards New Zealand thought it would be useful to provide clarification about the relationship between the International Organization for Standardization (ISO) greenhouse gases Standard ISO 14064, and the Greenhouse Gas (GHG) Protocol.

ISO, a network of national Standards institutes from 161 countries, developed the ISO 14064 Standard in 2006 for the quantification, monitoring, reporting, and verification of project and entity level greenhouse gases (GHGs).

ISO 14064 is in three parts. The first part specifies requirements for designing and developing organisation or entity-level GHG inventories. The second part details requirements for quantifying, monitoring, and reporting emission reductions and removal enhancements from GHG projects. The third part provides requirements and guidance for the conducting of GHG information validation and verification.

The GHG Protocol and ISO 14064 are not competing standards

ISO 14064 is intended to build upon, support, and take forward, the existing work of the GHG Protocol. They are complementary documents, with ISO identifying what to do, and the GHG Protocol explaining how to do it.

Organisations developing GHG inventories, especially those that will seek independent verification, can benefit from using both the ISO Standard and the GHG Protocol as references. In 2007, a Memorandum of Understanding was signed between ISO – World Resources Institute – Would Business Council for Sustainable Development – addressing technical cooperation, promotion and training.

One differentiation is that the GHG Protocol and ISO 14064 use different ways to explain what is counted and what is not counted when calculating greenhouse gas emissions. The GHG Protocol discusses Scope I, II, and III, while ISO 14064 differentiates between 'direct', 'indirect' and 'indirect other'.

The GHG Protocol identifies, explains, and provides options for GHG inventory best practices, while ISO 14064 establishes verifiable minimum standards for compliance with these best practices.

Greenhouse gases Standard enables businesses to use ISO 14064 certification to leverage their GHG emission performance

While the GHG Protocol offers consistent best practice approaches, organisations cannot become certified to the requirements of the GHG Protocol.

ISO 14064 helps enable businesses to use ISO 14064 certification to leverage their exemplary GHG emission performance into a competitive advantage, and to:

  • measure and report their GHG emissions consistently with the rest of the world
  • prepare global inventories using a single set of rules and procedures
  • compare themselves against their counterparts throughout the world in terms of GHG performance.
