human capital disclosure: ISO 30414 and CSRD

a metric-by-metric readiness guide to ISO 30414:2025 and the workforce disclosures inside the revised EU standards

53 pages · 45 min read

Human capital reporting has moved from voluntary guidance towards something closer to an audit trail. ISO published the second edition of ISO 30414 on 24 August 2025. It keeps the eleven human capital areas and adds a baseline set of 14 required metrics that apply to every organisation, whatever its size, sector or geography. It shifts from recommendations alone to auditable requirements, and adds coverage of human rights, labour relations, productivity, ethics, wellbeing and data governance.

The EU narrowed and rewrote its regime in parallel. Directive (EU) 2026/470 raised the CSRD threshold to more than 1,000 employees and more than 450 million euro in net turnover, and ended the phased waves. The European Commission adopted revised reporting standards on 3 July 2026, cutting mandatory datapoints by more than 60% and applying from financial years starting 1 January 2027. ESRS S1, the own workforce standard, still carries the disclosures that HR owns.

Written for CHROs, people analytics leads and reporting owners who have to produce workforce numbers that survive assurance. Includes a metric-by-metric readiness checklist, an ISO 30414 to ESRS S1 mapping, a data lineage template, and a two-year plan to the FY2027 reporting year.

what’s inside

  1. what changed in human capital reporting, and when
  2. ISO 30414:2025: eleven areas and the required metrics
  3. ESRS S1: the own workforce disclosures HR owns
  4. where ISO 30414 and ESRS S1 overlap, and where they diverge
  5. the metric-by-metric readiness checklist
  6. data lineage: proving a number to an assurance standard
  7. pay transparency and the reporting it pulls forward
  8. a two-year readiness plan to the FY2027 reporting year

what you’ll be able to do

  • score every ISO 30414 and ESRS S1 metric on data source, owner and assurance readiness
  • map ISO 30414 metrics to ESRS S1 disclosures so one data set serves both frameworks
  • build a data lineage record for each disclosed metric, from system of record to published figure
  • identify the metrics your HRIS cannot yet produce, and what to change before FY2027
  • agree who signs off each workforce number, and what evidence sits behind the signature
