IFRS S2 + NIS B-1 for Media & Entertainment in Mexico: 2026 Guide
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.
Televisa and TV Azteca are BMV issuers with binational operations (USA/Mexico) where Mexican IFRS S2 regulation coexists with SEC climate disclosure requirements — forcing them to align emissions methodologies between CNBV and SEC simultaneously, with different geographic perimeters and accounting consolidation.
Why IFRS S2 + NIS B-1 Applies Differently in Media & Entertainment
CFO and Sustainability Director of BMV-listed media groups
Distributed transmission infrastructure (towers, repeaters, satellite transponders) — >200 transmission sites in Mexico with low individual energy consumption but no aggregate consumption telemetry for Scope 1+2
OTT content data centers (streaming) — energy consumption in own data centers vs. cloud (AWS/Azure) where emissions allocation per subscriber/streaming hour has no standard IFRS S2 methodology
Audiovisual production — energy consumption on sets, cranes, diesel generators at external locations, which varies enormously by production and is not recorded in ERP
E-waste from broadcast equipment (cameras, playout servers, encoders) — technology refresh accelerated by 4K/8K generates high-value electronic waste without a formal take-back program
Critical IFRS S2 + NIS B-1 KPIs for Media & Entertainment
| Required KPI | Data Source | Difficulty |
|---|---|---|
| PUE of own data centers (ratio, target <1.5) | Purchased electricity (Scope 2) | High 🔴 |
| GHG per hour of content produced (kgCO2e/hour produced) | Electricity bills (Scope 2) | High 🔴 |
| Percentage of renewable energy in own infrastructure (%) | Cat 11 - Consumo energético de audiencias (TV en hogares) | High 🔴 |
| Electronic waste recycled or repurposed per year (tonnes) | HR / payroll system | Medium 🟡 |
| Emissions intensity per active OTT subscriber (kgCO2e/subscriber/year) | ERP / accounting system | Medium 🟡 |
Hard-to-Collect Data in Media & Entertainment
Electricity consumption of analog/digital transmission towers scattered across the country (many without smart meters, only bimonthly estimated CFE bill)
PUE (Power Usage Effectiveness) efficiency of own data centers vs. emissions allocation from shared cloud data centers
Broadcast electronic waste inventory by type and retirement year (requires integration with fixed assets registered in accounting system)
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.
Checklist: 8 Steps to Comply with IFRS S2 + NIS B-1 in Media & Entertainment
- 1
Mapping and reconciliation of all 30 IBSO indicators with IFRS S2 metrics requirements to avoid duplication of effort
- 2
Unified GHG emissions data collection for Scope 1, 2, and 3 serving both frameworks simultaneously without double measurement
- 3
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
- 4
Alignment of reporting calendars — the integrated sustainability report must meet both deadlines from a single data collection cycle
- 5
Implementation of robust internal controls over sustainability information capable of supporting third-party assurance under both frameworks from 2027
- 6
Connect data sources (ERP, meters, suppliers) to a centralized platform
- 7
Review with internal audit team and adjust consolidation perimeter
- 8
Generate report in CNBV/CINIF format ready for external assurance
