IFRS S1 for Health & Pharma in Mexico: 2026 Guide
IFRS S1 establishes general requirements for BMV and BIVA-listed issuers to disclose material information about sustainability-related risks and opportunities in their annual reports. CNBV made it mandatory starting January 2025, with the first report covering FY2025 data due in 2026. IFRS S1 acts as the umbrella standard that complements IFRS S2 on climate-specific matters.
The pharmaceutical/health sector is the only one in Mexico with specific sectoral environmental regulation (NOM-087 RPBI) that must integrate with the 30 IBSO indicators of NIS B-1 — a sector where CINIF and SEMARNAT regulate the same waste stream with different formats and reporting deadlines.
Why IFRS S1 Applies Differently in Health & Pharma
CFO and Sustainability Director of BMV-listed healthcare and pharmaceutical companies
Biological-Infectious Hazardous Waste (RPBI) — classification, weight, and final disposal required by NOM-087-SEMARNAT/SSA1-2002 that must align with NIS B-1 hazardous waste indicators
Pharmaceutical cold chain — energy consumption of refrigeration chambers at -2°C to -8°C and ultra-freezing at -80°C without sub-metering by product type or batch
Scope 3 Cat 1 for imported active pharmaceutical ingredients (APIs) — suppliers in India/China without carbon footprint data per API or production batch
Medical gases (nitrous oxide N2O — potent GHG with GWP 298) used in anesthesia without recovery systems in Mexican hospitals
Critical IFRS S1 KPIs for Health & Pharma
| Required KPI | Data Source | Difficulty |
|---|---|---|
| RPBI generated per occupied bed-day (kg/bed-day) | Purchased electricity (Scope 2) | High 🔴 |
| Energy consumption per equivalent surgical procedure (kWh/procedure) | Electricity bills (Scope 2) | High 🔴 |
| Water intensity per hospital bed or per pharmaceutical product unit | Cat 1 - APIs e ingredientes farmacéuticos importados | High 🔴 |
| Percentage of pharmaceutical waste with certified final disposal (%) | HR / payroll system | Medium 🟡 |
| N2O emissions per anesthetic procedure (kgCO2e/procedure) | ERP / accounting system | Medium 🟡 |
Hard-to-Collect Data in Health & Pharma
RPBI weight by category (infectious, pathological, sharps, pharmaceutical) — many Mexican hospitals do not disaggregate by category for NIS B-1 reporting
N2O consumption in anesthetic procedures per operating room (requires integration with medical gas management system)
Emission factor of imported APIs by supplier/country of origin for Scope 3 Cat 1
That is why manual Excel-based processes will not pass the 2027 assurance. Without automated traceability, an external auditor cannot verify the completeness or accuracy of emissions data.
