The ISO 14064 standards provides governments, businesses, regions and other organisations with a complementary set of tools for programs to quantify, monitor, report and verify greenhouse gas emissions.
The ISO 14064 standards supports organisations to participate in both regulated and voluntary programs such as emissions trading schemes and public reporting using a globally recognised standard.
The Standard has three parts:[1] ISO 14064-3 specifies requirements for selecting GHG validators/verifiers, establishing the level of assurance, objectives, criteria and scope, determining the validation/verification approach, assessing GHG data, information, information systems and controls, evaluating GHG assertions and preparing validation/verification statements.
The ISO 14064-3 verification standard is one of the standards accepted by the Carbon Disclosure Project, the widely used climate impact disclosure system, as a valid framework for measuring and reporting GHG emissions.
