Answer: Enterprise greenhouse gas verification is different from typical management system certification. To be precise, it does not belong to a management system certification project. Therefore, the requirements for greenhouse gas verification projects for verification agencies are also based on the ISO 14065:2007 standard, rather than the ISO 17021:2006 standard commonly used by management system certification agencies. At the same time, the mainstream management system certification accreditation agencies have not yet launched accreditation projects based on ISO 14064.

In specific implementation, greenhouse gas verification also has many different characteristics from typical management system certification, such as the object of greenhouse gas verification being the greenhouse gas report of a certain year; The greenhouse gas verification declaration issued does not have an expiration date; There is no requirement for annual supervision and audit for verification; Enterprises can apply for verification for one year at a time, or apply for verification for multiple past years at once.
