What alignment really means across ESRS, ISSB, GRI, and CDP

Alignment is not equivalence: the sources describe interoperability, mapping, and comparability, not interchangeable standards.

Climate is the most mature interoperability area because ESRS and ISSB were developed together and almost all ISSB climate disclosures are included in ESRS.

ESRS starts with double materiality, while CDP is positioned as a route to multiple market and regulatory demands rather than one shared materiality test across all frameworks.

Common principles do not erase framework differences: CDP points to GHG Protocol and Accountability Framework alignment, but ESRS still keeps its own terms and disclosure structure.

A workable approach is one controlled dataset with a crosswalk, but each framework still needs its own boundary, methods, and comparative-data checks.
