IFRS S1 for Agribusiness 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.
Mexico's listed agribusiness sector faces the largest data gap between real and reported Scope 1 of all BMV sectors. Bachoco estimates that its methane emissions from enteric fermentation (Scope 1) could be 3-4x higher than what they report with IPCC Tier 1 factors — a significant restatement risk if the 2027 assurance auditor requires Tier 2.
Why IFRS S1 Applies Differently in Agribusiness
CFO and Sustainability Director of BMV-listed agribusiness companies
Enteric fermentation in bovine/porcine/poultry livestock (CH4 — Scope 1) — Tier 2 calculation requires animal census by species, breed, and production system that few agribusinesses have systematized
N2O emissions from nitrogen fertilizer use (Scope 1) — enormous variation by soil type, climate, and fertilizer formulation, with IPCC emission factors that differ from Mexican context
Deforestation in agricultural supply chain (Scope 3 Cat 1 from land use change) — grain suppliers in high-deforestation areas (Chiapas, Tabasco) without geospatial traceability
Water use in agricultural irrigation (NIS B-1 water Cat 1) — mixed sources (over-exploited aquifers, dams, own wells) without volumetric measurement per plot in contracts with producers
Critical IFRS S1 KPIs for Agribusiness
| Required KPI | Data Source | Difficulty |
|---|---|---|
| GHG per tonne of processed product (tCO2e/t, including biogenic) | Direct combustion (Scope 1) | High 🔴 |
| Water use intensity per kg of animal protein or tonne of grain (m³/t) | ERP / operating systems | High 🔴 |
| Percentage of suppliers with certified sustainable agricultural practices (%) | Cat 1 - Granos y materias primas agrícolas compradas | High 🔴 |
| Percentage of organic waste used as biogas or compost (%) | HR / payroll system | Medium 🟡 |
| Feed conversion ratio (FCR) by species as proxy indicator of emissions efficiency | ERP / accounting system | Medium 🟡 |
Hard-to-Collect Data in Agribusiness
Enteric fermentation and manure management emissions by livestock type disaggregated by production unit (Scope 1 Tier 2 requires data per pen/farm)
Water footprint of irrigation per supplier plot — most with individual CONAGUA water concessions without centralization
Historical land use change (10 years) on supplier plots for Scope 3 Cat 1 of agricultural raw materials (requires satellite analysis)
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.
