The International Organization for Standardization (ISO) has returned the first draft of its corporate net-zero standard for revisions, failing to clear the two-thirds approval threshold in a ballot that drew participation from 88 countries.

"ISO/DIS 14060 did not receive the level of approval required to advance in its current form," an ISO spokesperson said. The standard, formally titled ISO 14060 Standard for Net-Zero Aligned Organizations, was circulated to more than 170 national standards bodies over a 12-week consultation that closed Sept. 9.

Close to 5,000 comments were filed during that window. The volume underlines how contested the corporate net-zero rulebook has become, with national delegations now treating the standard as a procurement-relevant specification rather than an academic exercise.

What are the ISO voting thresholds?

ISO's process for advancing a draft International Standard requires two numerical gates:

• Approval from at least two-thirds of participating committee members voting
• Negative votes representing no more than one-quarter of all votes cast
• A return to committee for further work if either threshold is missed

ISO does not disclose how individual national bodies voted, citing its external communications policy. The tabulation behind the ISO 14060 rejection is not public. Two people familiar with the negotiations, who asked not to be named because they are unauthorized to comment, said fossil-fuel producing nations formed one bloc voting against the draft. Other "no" votes may reflect requests for more time on provisions governing how carbon credits can be used.

Why does this matter for circular-economy commitments?

The standard sits at the hinge between voluntary corporate climate claims and verifiable accounting. A multinational that aligns with ISO 14060 will get a market-recognized marker for its emissions strategy — one that procurement teams, financial auditors, and regulators can cite alongside recycled-content and circularity claims.

If ISO aligns 14060 with the Greenhouse Gas Protocol as intended, the standard becomes a translation layer between corporate net-zero pledges and the inventory methodology most large companies already run. That interchangeability matters for Scope 1, 2, and 3 disclosures filed under CSRD, the SEC climate rule, and emerging Asian frameworks.

What is the GHG Protocol–ISO convergence?

ISO and the GHG Protocol are working to unify their respective carbon accounting rules. A joint draft is due in early 2027, and the alignment is the reason ISO 14060 has drawn sustained interest this year. Companies do not want to align with a net-zero standard that drifts from the inventory methodology they already use to track Scope 3 across their supply chain.

ISO's annual general assembly runs Sept. 28 to Oct. 2 in Paris, where national delegations will have an early chance to signal what revisions they expect in a revised committee draft.

What happens next?

The ISO technical committee must now review the 5,000 submitted comments before deciding how to proceed. Open questions for the revision include:

• Whether carbon-credit rules will be tightened, loosened, or moved to a separate document
• Whether scope coverage for indirect emissions narrows or widens
• How the standard will reference the GHG Protocol convergence timeline

A redrafted ISO 14060 will then face a second ballot under the same two-thirds threshold. Until a revised draft wins approval, corporate buyers and procurement teams cannot cite ISO 14060 alignment as a settled disclosure claim.

The milestone now to watch: the committee's revision plan and the publication date of the next consultation draft, expected ahead of the 2027 GHG Protocol joint release. Companies compiling 2026 disclosures have the most reason to track that calendar.
