IFRS S2 + NIS B-1 for Logistics & Transport 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.
The Mexican logistics sector faces simultaneous pressure from IFRS S2 (listed issuers) and from multinational clients demanding carbon footprint data per shipment for their own CSRD/TCFD reports. DHL and Estafeta already receive Scope 3 Cat 4 requests from more than 200 corporate clients — the ability to report tCO2e per tonne-km is a growing commercial differentiator.
Why IFRS S2 + NIS B-1 Applies Differently in Logistics & Transport
CFO and Sustainability Director of BMV-listed logistics operators
Own fleet + third-party carriers — consolidating Scope 1 (own fleet) and Scope 3 Cat 4 (contracted transport) requires different methodologies and data that third-party carriers don't have
Fuel consumption per route/client not available in legacy TMS — GPS tracking systems capture times but not direct consumption
Refrigerated transport (cold chain) — consumption of refrigeration systems independent of the main engine, without sub-metering in >60% of the fleet
Empty runs accounted as Scope 1 of the operator or Scope 3 of the client? — GHG Protocol methodology for logistics still under discussion in the sector
Critical IFRS S2 + NIS B-1 KPIs for Logistics & Transport
| Required KPI | Data Source | Difficulty |
|---|---|---|
| tCO2e per tonne-km (Scope 1 + Scope 3 Cat 4 combined) | Direct combustion (Scope 1) | High 🔴 |
| Fuel efficiency of own fleet (km/liter by vehicle type) | ERP / operating systems | High 🔴 |
| Percentage of electric/natural gas/alternative fleet (%) | Cat 4 - Transporte upstream tercerizado | High 🔴 |
| Empty run rate (%) | HR / payroll system | Medium 🟡 |
| Cold chain emissions per refrigerated unit (kgCO2e/trip) | ERP / accounting system | Medium 🟡 |
Hard-to-Collect Data in Logistics & Transport
Fuel consumption of outsourced carriers per trip (requires trip sheet data that carriers don't digitize)
Emissions from refrigeration system (R-404A/R-452A) in refrigerated units — refrigerant leak measurement per unit
Average load factor per route for tCO2e per tonne-km calculation
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 Logistics & Transport
- 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
