GHG Protocol ↔ IFRS S2
How IFRS S2 uses GHG Protocol measurement concepts for Scope 1, Scope 2, and Scope 3 reporting.
A carbon accountant in Singapore opened the 《温室气体核算体系》企业标准 and found a definition: "Scope 1 emissions are direct greenhouse gas emissions from sources that are owned or controlled by the reporting entity." She had been calculating Scope 1 emissions for five years. She had never questioned the definition. Then IFRS S2 was published, and it required companies to disclose Scope 1 emissions using the GHG Protocol. The definition was no longer a guideline. It was a requirement.
IFRS S2 §27 requires companies to disclose their greenhouse gas emissions using the 《温室气体核算体系》企业标准. Scope 1 (direct), Scope 2 (indirect from purchased electricity), and Scope 3 (value chain). The GHG Protocol provides the measurement methodology: boundary setting, emission factors, data quality assessment. IFRS S2 provides the disclosure requirement: what to report, how to report it, and when.
The GHG Protocol was published in 2001. IFRS S2 was published in 2023. Twenty-two years apart, they are now inseparable. The carbon accountant in Singapore no longer chooses between frameworks. She uses the GHG Protocol to measure and IFRS S2 to disclose. The definition she had never questioned — "sources owned or controlled by the reporting entity" — is now the foundation of a global disclosure standard.
The GHG Protocol measures; IFRS S2 discloses. Two frameworks, 22 years apart, now inseparable in the carbon accounting workflow.
In Plain Language
GHG Protocol measures; IFRS S2 discloses. IFRS S2 §27 requires companies to use the 《温室气体核算体系》企业标准 for emissions reporting. The Protocol provides the measurement methodology — boundary setting, emission factors, data quality. IFRS S2 provides the disclosure requirements.
- The GHG Protocol measures; IFRS S2 discloses. Two frameworks, 22 years apart, now inseparable in the carbon accounting workflow.
- IFRS S2 §27 requires GHG Protocol methodology for Scope 1, Scope 2, and Scope 3 — the measurement framework becomes a disclosure requirement.
- The practical test is whether a carbon accountant can trace an emission figure from the GHG Protocol calculation through to the IFRS S2 disclosure without gap.
