Carbon Reporting for Wholesale and Distribution Companies
Carbon Reporting for Wholesale and Distribution Companies
Wholesale distributors, commodity traders, B2B distributors, and import-export businesses occupy a critical position in supply chains — and they are often among the first companies to receive carbon data requests from both their customers (who need their Scope 3 Category 1 data) and their suppliers (who ask about downstream logistics as their own Scope 3 Category 9).
The Carbon Profile of a Wholesale or Distribution Business
| Source | Scope | Notes |
|---|---|---|
| -------- | ------- | ------- |
| Own delivery fleet (diesel vans, HGVs) | 1 | Often the largest Scope 1 category |
| Forklift fleet (LPG or diesel) | 1 | Warehouse operations |
| Warehouse heating (gas) | 1 | Large warehouses have significant gas consumption |
| Warehouse electricity | 2 | Lighting, cold storage, racking systems, charging bays |
| Refrigerant in cold storage | 1 | High GWP refrigerants in refrigerated warehouses |
| Third-party haulage (outbound) | 3 (Cat 9) | Downstream transport |
| Third-party haulage (inbound) | 3 (Cat 4) | Upstream transport from your suppliers |
| Employee commuting | 3 (Cat 7) | Warehouse operatives, drivers, office staff |
Fleet Fuel Calculation
For a distribution company with 15 diesel vans and 3 articulated HGVs:
| Vehicle type | Annual km | Fuel consumption | Annual fuel | tCO2e Scope 1 |
|---|---|---|---|---|
| -------------- | ----------- | ------------------ | ------------- | ---------------- |
| Diesel van x 15 | 30,000 km | 0.12 L/km | 54,000 L | 144.7 tCO2e |
| HGV (articulated) x 3 | 80,000 km | 0.37 L/km | 88,800 L | 237.9 tCO2e |
Total fleet: approximately 382 tCO2e/year — a significant Scope 1 figure that will dominate the GHG inventory.
Cold Storage: A Special Case
Refrigerated warehouses have two emission sources that are often overlooked:
1. Electricity: Cold storage is extremely energy-intensive. A 1,000 m² refrigerated warehouse can consume 400,000–600,000 kWh/year. Apply your country grid factor to get Scope 2.
2. Refrigerants: Industrial refrigeration systems use large charges of high-GWP refrigerants (R-404A, GWP 3,922, for older medium-scale systems; ammonia for large installations — GWP of 0). Annual top-up records from your refrigeration maintenance contractor are essential for accurate Scope 1.
Transport Intensity Metrics
Many buyers request transport intensity (kgCO2e/tonne-km or kgCO2e/pallet-km) in addition to absolute totals. Calculate this as: total transport tCO2e x 1,000 / total tonne-km delivered. This metric helps buyers assess your logistics efficiency relative to competitors.
Responding to Retail, Food, and Manufacturing Buyers
Retail buyers (Tesco, Carrefour, Lidl, Aldi): Distribution companies supplying retail chains are asked for Scope 1 and 2 data with delivery fleet details and any third-party carrier environmental certification.
Food manufacturers (Nestlé, Unilever, Danone): Category 4 and 9 transport data is requested to populate their own Scope 3 calculations. Annual tonne-km by transport mode is the preferred data format.
Amazon Logistics: Third-party sellers and fulfilment partners using Amazon services receive sustainability assessment requests tied to Amazon's Climate Pledge commitments.
Generating Your Carbon Passport
DeCarbonOPS calculates Scope 1 fleet fuel, warehouse gas, and refrigerant emissions; Scope 2 warehouse electricity with country-specific grid factors; and Scope 3 Categories 3, 5, 6, and 7. For a delivery fleet of any size, entering total annual litres per fuel type gives you an accurate Scope 1 figure in under 20 minutes. Generate your Carbon Passport and use it in retail supplier portals, food industry sustainability questionnaires, and transport network operator qualification forms.
Frequently Asked Questions
How do I calculate HGV emissions if I use a mix of own fleet and contracted hauliers?
Own fleet HGVs fall in Scope 1 — use annual litres of diesel consumed from fuel card records. Contracted hauliers (third-party carriers delivering on your behalf) fall in Scope 3 Category 9 (outbound) or Category 4 (inbound). For contracted haulage, request tonne-km data from your logistics providers and apply DEFRA 2023 HGV factors (articulated 40t: 0.065 kgCO2e/tonne-km). If tonne-km data is unavailable, use spend-based proxy or estimate from distance and average load weight.
Is cold storage refrigerant always Scope 1 for a warehouse operator?
Yes — if you own or have operational control of the refrigeration equipment, refrigerant top-ups are Scope 1 under the GHG Protocol. Obtain annual F-Gas maintenance records from your refrigeration service contractor showing refrigerant type and kg added per year. Multiply kg x GWP for kgCO2e. For ammonia (NH3) systems, GWP = 0 so refrigerant leaks have zero direct GHG impact (though ammonia has other environmental hazards). For R-404A (GWP 3,922), even small leaks generate large Scope 1 figures.
What is the FORS (Fleet Operator Recognition Scheme) and does it replace GHG reporting?
FORS (Fleet Operator Recognition Scheme) is a road transport accreditation for operators in and around London. It covers safety, efficiency, and environmental performance including emissions, but it is a management system standard — similar to ISO 14001. FORS Gold certification documents that you have processes to measure and manage fleet emissions, but does not produce Scope 1/2/3 tCO2e figures for questionnaire responses. You still need a separate GHG calculation.
Do I need to report delivery emissions for products I sell but don't ship?
If the customer arranges and pays for collection (ex-works terms), the transport is outside your operational boundary and falls in the customer's Scope 3 Category 4. If you arrange delivery and invoice the freight cost to the customer, the transport falls in your Scope 3 Category 9 (downstream transport) even if the customer ultimately pays. The boundary question is: who arranges and controls the transport? That party owns the Scope 3 category.
How should distributors handle the boundary between Category 4 (inbound) and Category 9 (outbound) transport?
Category 4 covers all third-party transport from your suppliers to your warehouses — inbound freight you arrange or that your suppliers arrange on your behalf. Category 9 covers all third-party transport from your warehouses to your customers — outbound delivery you arrange. Own fleet for either direction is Scope 1. Map your logistics flows: supplier to warehouse = Category 4; warehouse to customer = Category 9; inter-warehouse movements using third parties = Category 4 (internal distribution). Own vehicles for all routes = Scope 1.
