IFRS S2 for Paper & Pulp in Mexico: 2026 Guide
IFRS S2 is the climate-specific standard adopted by CNBV as mandatory for all BMV and BIVA issuers starting January 2025, making Mexico the first country in North America to implement IASB's ISSB standards. Companies must report GHG emissions across all three scopes, conduct climate scenario analysis, and disclose how climate change impacts their strategy and financial model. Limited assurance of the report by an external auditor will be required starting with the 2027 reporting cycle.
The paper-pulp sector is the only one in Mexico where the main energy source (biomass) can be carbon-neutral under IFRS S2 — but only if FSC/PEFC chain of custody is demonstrated, which Bio Pappel and Copamex don't have for their entire bagasse supply. The absence of certification turns biomass into fossil-equivalent Scope 1 for IFRS S2 purposes, potentially doubling the reported footprint vs. the real sustainable one.
Why IFRS S2 Applies Differently in Paper & Pulp
CFO and Sustainability Director of BMV-listed paper and cellulose product producers
Biomass combustion in boilers (sugarcane bagasse, wood) — carbon neutrality accounting for biomass under IFRS S2/GHG Protocol requires demonstrating sustainable forest chain of custody (FSC/PEFC) that Mexican bagasse suppliers don't have
Industrial liquid effluents (BOD, COD, AOX) — continuous measurement required by SEMARNAT but integration with NIS B-1 water indicators without common methodology
Recycled fiber (recovered paper) — fiber percentage and origin for chain of custody, where domestic recovered paper has less traceability than certified imports
Pulp bleaching with elemental chlorine free (ECF/TCF) — organochlorine compound emissions measured in AOX without standard GHG conversion for IFRS S2 reporting
Critical IFRS S2 KPIs for Paper & Pulp
| Required KPI | Data Source | Difficulty |
|---|---|---|
| Specific energy consumption per tonne of paper produced (GJ/t) | Direct combustion (Scope 1) | High 🔴 |
| Water consumption per tonne of paper (m³/t) | Electricity bills (Scope 2) | High 🔴 |
| Percentage of fiber from FSC/PEFC certified sources (%) | Cat 1 - Fibra de madera/bagazo comprada | High 🔴 |
| GHG intensity per tonne produced (tCO2e/t, excluding certified biomass) | HR / payroll system | Medium 🟡 |
| BOD5 load in effluents per tonne of paper (kg/t) | ERP / accounting system | Medium 🟡 |
Hard-to-Collect Data in Paper & Pulp
Biomass emission factor (bagasse/wood) with chain of custody certification to demonstrate carbon neutrality under IFRS S2 (requires FSC or equivalent supplier audit)
Pollutant load in effluents (BOD5, COD, TSS, AOX) per discharge point integrated with GHG inventory for dual reporting
Percentage of post-consumer vs. pre-consumer recycled fiber with geographic origin traceability
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.
