GHG Protocol and ISO are building one standard

A company doing carbon accounting today reads two sets of standards: GHG Protocol and ISO 14064-1. On 29 July 2026 came an announcement that the two are to become one. ## What is being brought together The scope is **"GHG Protocol's Scope 1, Scope 2, Scope 3 and Action and Market Instrument (AMI) standards, and ISO's 14064-1 standard"**, and the outcome is **"a single co-branded corporate standard"**. A timetable came with it. **Public consultation on the integrated corporate standard is scheduled for Q2 2027.** A standard development plan (SDP) document for the integrated corporate standard was posted on the same date. The announcement positions this as **a key milestone on the COP30 action agenda**. ## Scale The recent Scope 2 consultation drew **close to 1,100 responses from 56 countries**. Consultation on the integrated standard folds those processes into one. ## In the next article The first question anyone asks is "so does the reporting we do now have to change". The answer is in the next piece. ※ This article cites the announcement published by GHG Protocol; what is described here is at the proposal and planning stage. --- This article expands one section of LCS international standards analysis 1, *Two Standards Become One*. The full report works from GHG Protocol's published announcement and partnership FAQ as primary sources, and marks anything still at proposal stage as such.
