Carbon Footprint Reporting for Belgian SMEs: A Practical Guide
Carbon Reporting for Belgian SMEs: Grid Factor, Data Sources, and Questionnaire Response
Belgium is home to thousands of SME suppliers to large European manufacturers, food companies, logistics firms, and public sector buyers. Many Belgian companies are now receiving sustainability questionnaires for the first time as their customers implement CSRD supply chain requirements. This guide explains what Belgian SMEs need to know.
Belgium's Electricity Grid Factor
Belgium has a mixed electricity grid with nuclear, natural gas, wind, and solar generation. The carbon intensity for 2022 (IEA source) is approximately:
| Country | Grid factor (kgCO2e/kWh) |
|---|---|
| --------- | -------------------------- |
| Belgium | 0.167 |
| Netherlands | 0.270 |
| France | 0.052 |
| Germany | 0.380 |
| UK | 0.193 |
For a Belgian SME consuming 80,000 kWh/year of electricity, Scope 2 emissions are: 80,000 x 0.167 = 13.4 tCO2e. Belgium's nuclear generation keeps the grid factor lower than Germany or the Netherlands, though higher than France.
What Data Do Belgian SMEs Need to Collect?
For Scope 1: - Annual gas consumption (m³) from Fluvius, Sibelga, or ORES bills - Diesel and petrol for company vehicles (litres from fuel cards or expense records) - Refrigerant top-ups (kg, from F-Gas maintenance records if applicable)
For Scope 2: - Annual electricity consumption (kWh) from your supplier bill or Fluvius meter data
For Scope 3: - Annual waste (kg by disposal route — landfill, recycling, incineration) from your waste contractor - Business travel km (flights, rail, company car personal use) - Employee commuting (approximate daily km per employee, working days)
Most Belgian SMEs can assemble this data in 2–3 hours from their utility bills, fleet management records, and HR data.
Responding to Specific Belgian Buyer Questionnaires
AB InBev / Anheuser-Busch: The Voyager Plant Optimisation programme requests Scope 1 and 2 data from Belgian suppliers. GHG Protocol methodology required.
Proximus: Supplier sustainability programme requests Scope 1, 2, and 3 data via their supplier portal. Carbon Passport URLs accepted as supporting evidence.
Beaulieu International Group, Umicore, Solvay: Large Belgian manufacturers with CSRD-driven supply chain requirements are rolling out questionnaire programmes. Most accept GHG Protocol calculations from SMEs without third-party verification in year 1.
Public procurement (BOSA, regional governments): Belgian public procurement is increasingly incorporating environmental criteria. Federal Purchasing Central and regional equivalents are beginning to request environmental performance data.
Using French vs English Questionnaire Fields
Belgian questionnaires arrive in Dutch, French, or English depending on the buyer. The numbers you need are the same in any language. Keep your Scope 1/2/3 figures in a single document (or Carbon Passport) so you can copy the same numbers regardless of the questionnaire language.
Generating Your Carbon Passport
DeCarbonOPS applies the correct Belgian grid factor (0.167 kgCO2e/kWh) automatically. Enter your utility data and fuel records, complete the calculation in under 20 minutes, and generate a Carbon Passport with a public verification URL. Share the URL in any questionnaire that requests supporting documentation — it works for Belgian, Dutch, German, and French buyers alike.
Frequently Asked Questions
What is the correct electricity grid factor for Belgium?
The IEA 2022 grid carbon intensity for Belgium is approximately 0.167 kgCO2e/kWh. Belgium's mix includes nuclear (approximately 40%), natural gas, wind, and solar. This places Belgium between France (0.052) and Germany (0.380). For a Belgian SME consuming 80,000 kWh/year, Scope 2 = 80,000 x 0.167 = 13.4 tCO2e.
How do I get my electricity consumption data from Belgian utility bills?
Belgian electricity bills from Fluvius (Flanders), Sibelga (Brussels), or ORES (Wallonia) show annual consumption in kWh. Use the annual consumption figure from your year-end statement or DSO meter reading. If your bill is monthly, sum the 12 monthly consumption figures. The figure you need is kWh consumed, not the cost in euros.
Which Belgian procurement frameworks are asking suppliers for carbon data?
Active programmes include: AB InBev Voyager Plant Optimisation, Proximus supplier portal, Colruyt Group sustainability assessment, Beaulieu International Group supply chain programme, UCB supplier qualification, and federal and regional government procurement (BOSA). EU-headquartered multinationals buying from Belgian suppliers including IKEA Belgium and Delhaize/Ahold are also requesting CSRD-compatible data.
Does the Belgian carbon reporting requirement differ for Flemish vs Walloon companies?
The carbon data required by procurement buyers is the same regardless of region — it follows the GHG Protocol Corporate Standard, which has no regional variation within Belgium. Report using GHG Protocol methodology consistently across regions. The regulatory frameworks at regional level (Vlaamse Milieumaatschappij in Flanders, SPAQuE in Wallonia) apply primarily to industrial operators and do not affect the questionnaire requirements for SME suppliers.
Can I report my carbon data in Dutch or French, or does it need to be in English?
The numerical data (tCO2e by scope) is language-neutral. If a questionnaire is in Dutch or French, enter your figures in the relevant fields in the same way as you would in English. If you are providing supporting documentation (a methodology statement, a Carbon Passport), English is universally accepted by Belgian enterprise buyers. A Carbon Passport URL works in any language questionnaire — the verification page is internationally accessible.
