Scope 1 2 3 Emissions: A Complete Guide for Food Businesses
Food systems account for around a third of global greenhouse gas emissions. For restaurants, caterers, hotels, and food producers, the vast majority of that impact sits outside the kitchen—in agricultural supply chains, ingredient sourcing, and the logistics that connect farm to fork.
Scope 1, 2, and 3 emissions are the framework that makes that full picture visible. Understanding where your emissions sit across all three scopes is no longer optional for most food businesses. It is required by regulation, expected by clients and procurement partners, and foundational to any credible net zero strategy.
This guide covers what each scope means, where food businesses' emissions actually concentrate, how to calculate and report them, and what different regulatory frameworks require.
What Are Scope 1, 2, and 3 Emissions?
Scope 1, 2, and 3 emissions are defined by the Greenhouse Gas Protocol Corporate Standard—the globally recognized framework for measuring and reporting corporate greenhouse gas emissions. Together, they cover every emission a business is responsible for, from direct operations through to the full value chain.
Scope 1: Direct Emissions
Emissions from sources owned or directly controlled by the business. For food businesses, this includes: Gas-fired kitchen equipment (ovens, fryers, grills, steamers), owned refrigeration and the refrigerant leakage associated with it, company-owned or leased delivery vehicles, on-site boilers and heating systems, and any fuel combusted directly in business operations.
Scope 1 is typically the easiest to measure accurately, since the data comes from fuel consumption records and refrigerant logs that most businesses already track.
Scope 2: Indirect Energy Emissions
Emissions from purchased electricity, heat, steam, or cooling. For food businesses, this means: Electricity purchased for kitchen equipment, lighting, refrigeration, and HVAC, district heating or cooling purchased from external suppliers, and electricity used across all sites, including offices and logistics facilities.
Scope 2 emissions are calculated using either a location-based method (average grid emission factor for the region) or a market-based method (reflecting actual energy contracts and renewable energy certificates). The market-based method is preferred under CSRD and most major reporting frameworks.
Scope 3: Value Chain Emissions
All other indirect emissions that occur across a business's value chain — both upstream (before goods reach the business) and downstream (after they leave). The GHG Protocol divides Scope 3 into 15 categories. For food businesses, the most significant are:
Category 1: Purchased goods and services—the carbon embedded in every ingredient, product, and consumable purchased. For most food businesses, this is by far the largest category.
Category 4: Upstream transportation and distribution—emissions from transporting ingredients and products to the business's facilities.
Category 5: Waste generated in operations—emissions from food waste and packaging waste sent to landfill or incineration.
Category 11: Use of sold products (food producers)—emissions associated with how customers prepare and consume products.
Category 12: End-of-life treatment of sold products (food producers)—packaging and food waste at the consumer stage.

Where Food Businesses' Emissions Actually Sit
The distribution of emissions across the three scopes looks very different for food businesses compared to most other industries.
In a typical manufacturing or services company, Scope 1 and 2 represent a meaningful share of total emissions. In food businesses, that pattern inverts dramatically. Scope 3—primarily Category 1 purchased goods—accounts for 80–95% of total emissions in most food operations. In other words, the carbon is in the supply chain, embedded in what is grown, raised, processed, and transported before it ever arrives.
This has a direct implication for strategy: reducing Scope 1 and 2 emissions through kitchen electrification or renewable energy purchasing addresses only a small fraction of total climate impact. Meaningful progress on net zero for a food business requires engaging Scope 3, specifically the ingredient and supplier decisions that drive Category 1.

What This Looks Like by Sector
Contract Catering and Foodservice Operators
Scope 1 is typically modest—gas kitchen equipment and possibly a small vehicle fleet. Scope 2 covers site electricity. Scope 3 Category 1 dominates, often representing 85–92% of total emissions, concentrated in protein-heavy menu items where ingredient-level variation is largest.
Hotels and Hospitality Groups
Scope 1 includes on-site boilers, kitchen gas, and owned vehicles. Scope 2 covers electricity across all hotel facilities. Scope 3 is split between food and beverage operations (Category 1), guest travel (Category 6, typically excluded from operational reporting), and supply chain logistics. For food-focused reporting, Category 1 from F&B procurement is the dominant operational Scope 3 category.
Food Producers and Manufacturers
Scope 1 covers manufacturing energy and on-site transport. Scope 2 covers factory electricity. Scope 3 is split across upstream agricultural inputs (Category 1), outbound logistics (Category 9), and use-of-product emissions (Category 11) depending on the product type. Agricultural production typically drives 70–85% of total emissions for most food product categories.
How Scope 3 Category 1 Is Calculated
Category 1 is the most data-intensive Scope 3 category for food businesses, because it requires emissions data at the ingredient and product level rather than at a high level of aggregation.
The GHG Protocol permits two approaches:
Spend-Based Calculation
Maps financial expenditure data to industry-average emission factors by spend category. Accessible as a starting point but produces estimates too coarse for meaningful reduction planning. It cannot distinguish between a beef dish and a vegetable dish of equivalent cost, despite their emissions profiles being dramatically different. Acceptable for initial disclosure but not sufficient for CSRD-grade reporting or target-setting.
Activity-Based Calculation
Maps actual quantities of ingredients purchased to LCA-derived emission factors specific to each ingredient. This is the approach that produces data precise enough to inform procurement decisions, menu optimization, and supplier engagement. It requires:
• Ingredient-level purchasing data (quantities, not just spend)
• Emission factors derived from Life Cycle Assessment (LCA) research, aligned with ISO 14067
• Clearly defined system boundaries (typically cradle-to-gate or cradle-to-retail)
• Consistent methodology applied across reporting periods
The formula at dish or recipe level is straightforward:
Carbon footprint (kg CO₂e) = Quantity of ingredient (kg) × Emission factor (kg CO₂e/kg)
For a complete evaluation of carbon accounting platforms that handle food-specific Scope 3 calculation, see the Carbon Accounting Software Buyer's Guide for Food Businesses. To understand what carbon accounting means at the organizational level and when to start, see What Is Carbon Accounting?.
Sum across all ingredients in a recipe to get dish-level emissions. Aggregate across all dishes and purchasing to get Category 1 totals.
The complexity—and the competitive advantage—lies in the quality and specificity of the emission factors. A global average for "beef" masks significant variation by origin, farming system, and feed composition. Origin- and production-method-specific factors produce more accurate results, particularly for high-impact ingredients where variation is most pronounced.
Klimato's database covers 4,000+ ingredients across 100+ countries, with multiple emission factor variations per ingredient derived from peer-reviewed LCA research, reviewed by the Swedish Environmental Research Institute (IVL) and validated against the Coolfood Methodology (WRI).

Scope 1, 2, and 3 in the Context of CSRD
The Corporate Sustainability Reporting Directive requires companies in scope to disclose Scope 1, 2, and 3 emissions under ESRS E1, with a level of rigor comparable to financial reporting.
For food businesses, CSRD Scope 3 obligations specifically require:
• Disclosure of all material Scope 3 categories—Category 1 is typically material for any food business, given that ingredient sourcing represents both a significant environmental impact and a potential financial risk under double materiality assessment
• Explanation of the methodology used to calculate Scope 3, including data sources, system boundaries, and assumptions
• Year-on-year tracking to demonstrate progress against targets
• Alignment with GHG Protocol Corporate Standard as the underlying calculation framework
Businesses cannot exclude Scope 3 on the basis of data complexity—CSRD explicitly requires engagement with material categories regardless of how difficult they are to calculate. This is where the data foundation matters most: ingredient-level, activity-based calculation is what makes CSRD-grade Scope 3 disclosure credible and auditable.
For a full breakdown of CSRD requirements for food businesses, see How to Prepare CSRD Reporting for Food Businesses. For the relationship between GHG Protocol and CSRD methodology, see GHG Protocol vs. CSRD.
Scope 1, 2, and 3 in the Context of SBTi
Science-Based Targets require emissions reductions aligned with climate science across all three scopes. For food businesses, SBTi has introduced FLAG (Forest, Land, and Agriculture) guidance that separates agricultural supply chain emissions from fossil fuel emissions, requiring distinct reduction pathways for each.
FLAG emissions—including land-use change, agricultural production, and deforestation-linked emissions—sit primarily in Scope 3 Category 1 for food businesses. Setting credible SBTi FLAG targets requires the same ingredient-level data foundation as CSRD reporting: the data serves both purposes.

How to Report Scope 1, 2, and 3 Emissions
Scope 3 reporting is the most data-intensive part of the process for food businesses, because it requires ingredient
and supplier-level data rather than just operational metrics.
1. Establish your boundary and baseline year: Define which entities, sites, and activities are included in your reporting boundary. Select a baseline year that reflects normal operations and can serve as the reference point for measuring progress. Document the boundary clearly, CSRD requires it to be auditable.
2. Collect Scope 1 and 2 data: Gather fuel consumption records (gas, diesel, LPG), refrigerant top-up logs, and electricity consumption data across all sites. Convert to CO₂e using standard emission factors from national inventories or your energy supplier.
3. Map Scope 3 categories by materiality: Identify which of the 15 Scope 3 categories are material for your business. For food businesses, Category 1 is almost always material. Category 4 (upstream transport), Category 5 (waste), and Categories 11–12 (for producers) are commonly material depending on the business type.
4. Build activity-based Category 1 data: Connect procurement data to ingredient-level emission factors. This is where data quality most directly affects reporting credibility. Spend-based approaches are acceptable for initial disclosure but should be progressively replaced with activity-based calculation as data maturity improves.
5. Aggregate and disclose: Combine Scope 1, 2, and 3 data into a total emissions inventory. Prepare disclosures aligned with the relevant framework—CSRD/ESRS E1, GHG Protocol, GRI, or all three. Ensure methodology is documented clearly enough to withstand third-party verification.
6. Set reduction targets and track progress: Use the baseline inventory to set science-aligned reduction targets. Track ingredient-level changes, supplier engagement outcomes, and operational efficiency improvements against those targets year-on-year.

What are Scope 1, 2, and 3 emissions?
Scope 1, 2, and 3 are the three categories defined by the GHG Protocol for measuring a company's total greenhouse gas impact. Scope 1 covers direct emissions from owned or controlled sources. Scope 2 covers indirect emissions from purchased energy. Scope 3 covers all other indirect emissions across the value chain—for food businesses, this includes agricultural production, ingredient sourcing, packaging, transport, and waste.
Which scope is largest for food businesses?
Scope 3, by a significant margin. In most food businesses, Scope 3 accounts for 80–95% of total emissions, driven primarily by ingredient procurement and agricultural production under Category 1. Reducing Scope 1 and 2 through electrification or renewable energy addresses only a small fraction of total climate impact—the majority of the opportunity lies in Scope 3.
What is Scope 3 Category 1 and why does it matter for food businesses?
Category 1 covers purchased goods and services—the carbon embedded in every ingredient and product a food business buys. It is almost always the largest single emissions category for food operators, and the one that requires the most granular data to calculate credibly. Spend-based estimates can't distinguish between a beef dish and a vegetable dish of equivalent cost; ingredient-level, activity-based calculation is what produces data specific enough to drive decisions.
Is Scope 3 reporting mandatory?
For companies in scope of CSRD, yes—Scope 3 disclosure is mandatory under ESRS E1, and material categories cannot be excluded on the basis of complexity. In the UK, Scope 3 is not yet universally mandatory but is increasingly required by corporate procurement, SBTi commitments, and supply chain pressure from clients with their own Scope 3 obligations. In practice, food businesses working with large corporate clients often face de facto Scope 3 requirements regardless of regulatory status.
How does Scope 3 reporting connect to CSRD?
CSRD requires companies to disclose all material Scope 3 categories under ESRS E1. For food businesses, Category 1 purchased goods is typically material under double materiality assessment. CSRD requires auditable methodology, documented assumptions, year-on-year tracking, and alignment with GHG Protocol—all of which require activity-based, ingredient-level data rather than high-level estimates.
What data do food businesses need to calculate Scope 3 Category 1?
At minimum: ingredient quantities purchased (not just spend), and emission factors for each ingredient derived from LCA research aligned with ISO 14067. More precise results come from origin- and production-method-specific factors rather than global averages, and from supplier-level data where available. The same data supports CSRD disclosure, SBTi target-setting, and procurement-level carbon reporting to clients.
How does Klimato help with Scope 1, 2, and 3 reporting?
Klimato automates Scope 1–3 calculation and reporting for food businesses, connecting procurement, recipe, and operational data to a database of 4,000+ ingredient-level emission factors across 100+ countries. The platform produces ingredient-by-ingredient Category 1 calculations that are GHG Protocol-aligned, ISO 14067-compliant, and CSRD-ready, alongside Scope 1 and 2 tracking for complete emissions inventory management.
