ISO 14064

ISO 14064 is the international standard for GHG quantification, reporting, and verification. Part 1 specifies principles and requirements for organisation-level GHG inventories. Part 2 covers project-level quantification, monitoring, and reporting. Part 3 provides requirements for validation and verification of GHG assertions. ISO 14064-aligned verification is required under India's CCTS, and is used globally for third-party GHG assurance. GSustain provides GAB-accredited ISO 14064 verification.
