ISO 14064 GHG Inventory Verification

The organization quantified its greenhouse-gas inventory for a stated reporting period and organizational boundary following ISO 14064-1, and — where an ISO 14064-3 verification statement exists — an independent body verified that inventory to a stated assurance level.

• That emissions are low or falling — verification confirms the inventory was measured and reported correctly, not that the numbers are good.
• Product-level carbon footprints — that is ISO 14067 territory, covered by a product carbon footprint report, not this.
• Carbon-neutrality claims — an inventory is an input to such claims, never the claim itself.
• Periods or entities outside the stated reporting period and organizational boundary.

• Has Corporate ESG Assessment or Disclosure →

Expiry matters — check the certificate is current.

An ISO 14064-1 inventory alone is self-prepared — insist on the ISO 14064-3 verification statement from an independent body.

Check the assurance level (limited vs reasonable) — they carry very different weight.

Verification applies only to the stated reporting period; last year's statement says nothing about this year.
