Carbon Accounting

Scope 1, Scope 2, Scope 3, emission factors, value-chain evidence, and verification-ready carbon data.

The boardroom was quiet enough to hear the projector fan. On the screen was a single line item: climate-related financial risk. Twelve directors looked at it. The question was not whether it mattered. The question was whether anyone could prove it.

That is the practical problem behind Carbon Accounting. IFRS sustainability disclosure is not a marketing exercise. It is a discipline for turning scattered operating facts into investor-useful financial information.

The page begins with the human difficulty because the technical requirement only makes sense after the problem is visible: someone must decide what is material, what evidence is sufficient, and how the disclosure connects back to financial statements.

Scope 1, Scope 2, Scope 3, emission factors, value-chain evidence, and verification-ready carbon data.

  • Carbon Accounting is treated as decision-useful reporting information, not optional ESG storytelling.
  • The evidence standard is source-first: every technical claim should trace to IFRS S1, IFRS S2, SASB industry guidance, or a named regulator.
  • The practical test is auditability: a reviewer should be able to move from report sentence to source document without guessing.

Technical Requirements

The technical section translates Carbon Accounting into the minimum evidence and disclosure structure needed by ESG reporters, analysts, and auditors.

  • Disclosure requirement: document the source, owner, reporting boundary, measurement method, assumptions, review control, and IFRS or SASB reference.
  • Evidence standard: document the source, owner, reporting boundary, measurement method, assumptions, review control, and IFRS or SASB reference.
  • Technical implementation: document the source, owner, reporting boundary, measurement method, assumptions, review control, and IFRS or SASB reference.
  • Assurance consideration: document the source, owner, reporting boundary, measurement method, assumptions, review control, and IFRS or SASB reference.
