The International Organization for Standardization (ISO) also provides some general standards for

- greenhouse gas emissions at organisation level (ISO 14064 - 1) and

- greenhouse gas emissions at project level (ISO 14064 - 2).

Specifications to validate and verify relevant accountings are documented in (ISO 14064 - 3).
