IFRS S2 + NIS B-1 for Private Construction with Workday: Data Integration 2026
BMV and BIVA issuers face the unique challenge of simultaneously complying with IFRS S2 (CNBV) and NIS B-1 (CINIF) for the same fiscal year, implying two regulatory frameworks, two regulators, and potentially two external assurance processes. Without a centralized platform, companies end up with sustainability and finance teams operating in silos, collecting redundant data in non-auditable spreadsheets. The overlap between IBSO indicators and IFRS S2 metrics is significant but not total, requiring precise mapping.
Workday is exceptionally strong in social and governance data — the S and G pillars of ESG — but has no physical operations modules, so environmental data (emissions, water, waste) must be complemented from other sources. Climatta uses the Workday REST API to automatically extract the 12 NIS B-1 social indicators and combines them with environmental data from complementary sources, giving financial and services corporates a complete solution without forcing Workday data outside its domain.
Data Already in Your Workday
Your Workday already has most of the data IFRS S2 + NIS B-1 requires. Climatta extracts it automatically without manual work.
| IFRS S2 + NIS B-1 Requirement | Workday Module | Available |
|---|---|---|
| Mapping and reconciliation of all 30 IBSO indicators with IFRS S2 metrics requirements to avoid duplication of effort | HCM (Human Capital Management) | ✅ |
| Unified GHG emissions data collection for Scope 1, 2, and 3 serving both frameworks simultaneously without double measurement | Financials | ✅ |
| Management of two distinct assurance processes: CNBV's limited assurance under IFRS S2 and CINIF's review under NIS B-1, ideally with the same auditor | Prism Analytics | ✅ |
| Alignment of reporting calendars — the integrated sustainability report must meet both deadlines from a single data collection cycle | Payroll | ⚠️ |
| Implementation of robust internal controls over sustainability information capable of supporting third-party assurance under both frameworks from 2027 | Adaptive Planning | ⚠️ |
Complete social indicators for NIS B-1: exact headcount, voluntary and involuntary turnover, accident rate, and absenteeism from HCM
Gender pay gap and compensation equity by hierarchical level from Payroll for the IBSO equity indicator
Training hours per employee and category from HCM Learning for the human capital development indicator
Consolidated financial data from Financials and Adaptive Planning for ESG intensity normalization by revenue
Why Excel from Workday Will Not Pass the 2027 Assurance
No audit trail: the auditor cannot trace the data back to its source in Workday
Formula error risk: one miscalculated cell invalidates the entire report
No change history: impossible to demonstrate data integrity over time
Workday → Excel → report = 3 manual transformations with no governance control
