ESG Reporting Made Simple: Food Waste Templates & Frameworks

Executive Summary

ESG reporting requirements are expanding rapidly. Food service operations face increasing pressure to disclose environmental performance, particularly around waste generation and associated emissions.

This guide provides practical templates and methodologies for the major reporting frameworks relevant to food service: GRI 306 (Waste), Scope 3 Category 5 (Waste Generated in Operations), and SASB food service metrics.

The ESG Reporting Landscape

Mandatory vs Voluntary Reporting

The reporting landscape is shifting from voluntary to mandatory:

Mandatory (or soon to be)

• EU CSRD: Large companies must report from 2024
• UK SECR: Streamlined Energy and Carbon Reporting
• SEC Climate: Proposed US climate disclosure rules

Widely Adopted Voluntary

• GRI: Most used sustainability reporting framework globally
• SASB: Industry-specific metrics for investors
• CDP: Climate disclosure questionnaire
• TCFD: Climate risk framework

Why Food Waste Matters for ESG

Food waste is material for ESG reporting because:

1. Environmental impact: 8-10% of global GHG emissions come from food waste
2. Operational cost: Waste represents lost revenue and disposal costs
3. Stakeholder interest: Investors, customers, and employees care about food waste
4. Regulatory trajectory: Food waste reporting requirements are expanding

GRI 306: Waste

GRI 306 is the most commonly used standard for waste disclosure. The 2020 update requires more detailed reporting on waste management.

Disclosure Requirements

306-1: Waste generation and significant waste-related impacts

• Description of significant waste-related impacts
• Actions taken to address impacts

306-2: Management of significant waste-related impacts

• Waste management approach
• Processes for monitoring and evaluation

306-3: Waste generated

Waste Category	Weight (tonnes)
Food waste
Packaging
Other organic
Total

306-4: Waste diverted from disposal

Diversion Method	On-site	Off-site
Composting
Anaerobic digestion
Donation
Animal feed

306-5: Waste directed to disposal

Disposal Method	On-site	Off-site
Landfill
Incineration

Data Requirements

To complete GRI 306, you need:

• Total waste generated by category (kg or tonnes)
• Waste diversion pathway for each category
• Breakdown of disposal methods
• Year-over-year comparison

How Food Waste Monitoring Helps

Automated monitoring provides:

• Continuous weight data for total waste generated
• Category breakdown for food waste types
• Integration with diversion pathway tracking
• Audit-ready reports for verification

Scope 3 Category 5 Emissions

Scope 3 Category 5 covers emissions from waste generated in operations. For food service, food waste is typically the largest contributor.

Calculation Methodology

Step 1: Quantify waste by type

Waste Type	Weight (tonnes)
Food waste - plant-based
Food waste - animal products
Food waste - mixed
Packaging - paper/cardboard
Packaging - plastic

Step 2: Determine disposal method

Waste Type	Landfill	Incineration	Composting	Other
Food waste	%	%	%	%

Step 3: Apply emission factors

Emission factors (kg CO2e per tonne):

Waste Type	Landfill	Incineration	Composting
Food waste	440-670	21-91	10-50
Paper	460-1,100	21	10-50
Plastic	21	2,330	N/A

Factors vary by country and methodology. Use locally relevant factors where available.

Step 4: Calculate total emissions

Total emissions = Σ (Waste weight × Disposal % × Emission factor)

Example Calculation

A restaurant generating 50 tonnes of food waste annually:

• 30% to landfill: 50 × 0.3 × 580 = 8,700 kg CO2e
• 70% to composting: 50 × 0.7 × 30 = 1,050 kg CO2e
• Total: 9,750 kg CO2e (9.75 tonnes)

Reduction Opportunities

Category 5 emissions can be reduced by:

1. Preventing waste: Less waste = fewer emissions
2. Diverting from landfill: Composting has lower emissions than landfill
3. Capturing methane: Anaerobic digestion with energy recovery

SASB Food Service Metrics

SASB provides industry-specific metrics for food service operations.

Food & Beverage Sector Standard

Relevant metrics include:

FB-RN-150a.1: Food waste generated

• Total weight of food waste (tonnes)
• Percentage diverted from landfill

FB-RN-150a.2: Percentage of food purchased meeting environmental standards

• Locally sourced
• Sustainably certified

Hotel & Lodging Sector Standard

Relevant metrics include:

SV-HL-440a.1: Total water withdrawn Note: Water embedded in food waste is often significant

SV-HL-440a.2: Percentage of food waste diverted

Restaurant Sector Standard

FB-RN-150a.1: Food waste generated Report in tonnes, with breakdown by:

• Pre-consumer (prep waste)
• Post-consumer (plate waste)
• Spoilage

Data Collection Requirements

Minimum Data Requirements

To meet basic reporting requirements:

• Total food waste weight (weekly or monthly)
• Waste diversion pathway (landfill vs compost vs other)
• Annual trend data (at least 2 years)

Enhanced Data Requirements

For comprehensive ESG reporting:

• Food waste by category (protein, produce, bakery, etc.)
• Food waste by source (prep, plate, spoilage)
• Waste per cover or per guest night
• Emission factors for your specific disposal methods
• Third-party verification of waste data

Data Quality Considerations

Auditors and investors look for:

• Completeness: All material waste streams included
• Accuracy: Measured (not estimated) where possible
• Consistency: Same methodology year-over-year
• Verifiability: Documentation and audit trail

Getting Started

Step 1: Identify Required Frameworks

Determine which frameworks are mandatory or expected for your organisation:

• Publicly listed? Check securities requirements
• Operating in EU? CSRD may apply
• Responding to investor questionnaires? GRI/SASB typically requested

Step 2: Assess Current Data

Audit your current food waste data against requirements:

• What data do you have?
• What gaps exist?
• What methodology improvements are needed?

Step 3: Implement Monitoring

Deploy automated food waste monitoring to provide:

• Continuous weight data
• Category-level granularity
• Audit-ready documentation

Step 4: Build Reporting Processes

Establish internal processes for:

• Data collection and validation
• Calculation and verification
• Annual report preparation
• Continuous improvement
