The International Organization for Standardization (ISO), a network of national standards institutes from 147 countries, developed the ISO 14064 standard in 2006 for the quantification, monitoring, reporting, and verification of project and entity level greenhouse gases.

The standard is comprised of three parts. The first part specifies requirements for designing and developing organization 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. In fact, ISO 14064 is intended to build upon, support and take forward the existing work of the GHG Protocol. Most recently, 2007, a MoU has been signed between ISO-WRI-WBCSD addressing technical cooperation, promotion and training.

One differentiation is that while the GHG Protocol discusses Scope I, II and III, ISO 14064 differentiates between direct, indirect and indirect other. In addition, while the GHG Protocol offers consistent best practice approaches, organizations cannot become certified to the requirements of the GHG Protocol.

With this in mind, it is intended that ISO 14064 will enable businesses and international corporations to:

ISO 14064 certification gives opportunity for corporations to leverage their exemplary GHG emission performance into a competitive advantage.
