IFRS S2 for Food & Beverages 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 food sector faces double exposure in IFRS S1: physical risk from water stress in agricultural supply zones (Sonora, Sinaloa) and transition risk from single-use plastics regulation (General Waste Law). ESG investors demand disclosure of agricultural supply chain resilience under 1.5°C and 2°C scenarios.
Why IFRS S2 Applies Differently in Food & Beverages
Sustainability Director and Supply Chain Director of food groups listed on BMV with CNBV obligation to report IFRS S1/S2
Dominant Scope 3 category 1: agricultural ingredients (wheat, corn, sugarcane) whose footprint varies by region, season and supplier — impossible to use a single generic emission factor under IFRS S2
Water management in restricted aquifer zones: plants in over-exploited aquifers in Guanajuato, Jalisco and Sonora must report physical water risk under IFRS S1 with 2040 horizon
Own delivery fleet (thousands of vehicles) with fragmented diesel consumption by route and region: consolidating Scope 1 for fleet requires telematics not all of the network has
Food loss in cold chain: IFRS S2 connects with Scope 3 cat. 12 (waste disposal) but spoilage rate by temperature is sensitive operational data that commercial teams resist sharing
Critical IFRS S2 KPIs for Food & Beverages
| Required KPI | Data Source | Difficulty |
|---|---|---|
| Carbon intensity: tCO₂e per tonne of food produced | Direct combustion (Scope 1) | High 🔴 |
| Water consumption: m³ per tonne produced at plants with CONAGUA concession | Electricity bills (Scope 2) | High 🔴 |
| Percentage of food loss and waste in distribution chain | Cat 1 - Bienes agrícolas comprados | High 🔴 |
| Tonnes of packaging plastic: post-consumer recycled vs. virgin | HR / payroll system | Medium 🟡 |
| HFC refrigerant loss rate per year (kg recharged / kg inventory) | ERP / accounting system | Medium 🟡 |
Hard-to-Collect Data in Food & Beverages
Carbon footprint of agricultural ingredients by batch and supplier (wheat from Sonora vs. Sinaloa have different fertilization and transport factors)
LP gas consumption in baking processes at small affiliated bakeries not metered in real time
Volume and final destination of high-organic-load wastewater (BOD) at animal protein processing plants
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 in Food & Beverages
- 1
Reporting of GHG emissions Scope 1, 2, and 3 (full value chain) in metric tons of CO₂ equivalent
- 2
Climate scenario analysis aligned to TCFD using at least 1.5°C and 2°C as reference pathways
- 3
Identification and quantification of physical risks (chronic and acute) and transition risks
- 4
Disclosure of emissions reduction targets, including net-zero goals with interim milestones
- 5
Description of how climate risks and opportunities affect business model, strategy, and cash flows
- 6
Connect data sources (ERP, meters, suppliers) to a centralized platform
- 7
Review with internal audit team and adjust consolidation perimeter
- 8
