Structured Reporting Using XBRL

SASB's Digital Strategy

SASB’s digital strategy is aligned with our core mission of establishing standards for ESG reporting that facilitate communication between companies and investors. We have developed a suite of integration options to help organizations incorporate SASB standards into their platforms and commercial activities. Asset managers and asset owners; banks; data, analytics, and research firms; and corporate reporting software companies all license SASB frameworks and data.


SASB plans to fully support XBRL to make digital reporting easy for issuers and data aggregation & analytics easy for investors. SASB has been proactive in developing an XBRL version of our taxonomy.

In 2020, SASB announced our engagement with PwC to support in the development of a SASB XBRL taxonomy. As a result of this engagement, the initial draft version of the SASB XBRL taxonomy is now complete. SASB has submitted the draft taxonomy to the XBRL US Domain Steering Committee for formal review and approval. The review is now complete.

Draft Taxonomy Now Available

The draft taxonomy, preparer guide and supplemental materials are now available for review . The public comment period was open for a period of 60 days and ended on May 3rd, 2021. We will review the public comments received and determine how best to improve the taxonomy and release an updated version.

Additional Information

SASB recently held a webinar with XBRL US which discusses the SASB Standards and our vision for structured reporting using XBRL, including a demonstration of SASB’s XBRL taxonomy and panel discussions about how the process of preparing, extracting, and analyzing machine-readable ESG data will work in practice.

SASB utilizes Fujitsu XWand tools in its XBRL taxonomy creation process to enable structured reporting on SASB Standards.
