Carbon Footprint for Austrian SMEs: 2026 Reporting Guide
Carbon Footprint Austria SME: What Austrian Businesses Need to Know in 2026
The carbon footprint Austria SME landscape has shifted significantly over the past two years. Austrian SMEs face pressure from three directions simultaneously: CSRD supply chain data requests from large Austrian corporates, NaDiVeG (Nachhaltigkeits- und Diversitätsverbesserungsgesetz — Austria's sustainability reporting law) requirements flowing down to suppliers, and growing buyer scrutiny from German, Swiss, and Benelux customers.
Austria is a highly export-oriented economy — over 60% of Austrian SME revenue comes from cross-border customers. If your buyers are CSRD-regulated, they will eventually ask for your Scope 1, 2, and 3 figures.
Austrian Carbon Reporting Obligations: NaDiVeG and CSRD
NaDiVeG (Austria's implementation of the Non-Financial Reporting Directive) has applied to large Austrian public-interest entities since 2017. With CSRD transposition, this now extends to:
- Large companies (250+ employees, €40M+ turnover, €20M+ balance sheet): CSRD reporting from 2025
- Listed SMEs: CSRD from 2026 (voluntary ESRS standards available now)
- Unlisted SMEs: Not directly regulated — but affected via supply chain data requests
The ESRS (European Sustainability Reporting Standards) under CSRD require large companies to report their Scope 3 Category 1 emissions — which means they must collect carbon data from you as a supplier.

Austrian Emission Factors for 2026
For GHG Protocol-compliant carbon footprint calculations, Austrian SMEs should use:
| Energy Source | Emission Factor | Source |
|---|---|---|
| --- | --- | --- |
| Austrian grid electricity | 0.118 kgCO2e/kWh | E-Control / Austrian energy statistics |
| Natural gas (Erdgas) | 2.204 kgCO2e/m³ | DEFRA 2023 (EU-applicable) |
| Heating oil (Heizöl EL) | 2.520 kgCO2e/litre | DEFRA 2023 |
| Diesel (PKW/LKW) | 2.683 kgCO2e/litre | DEFRA 2023 |
| Petrol (Benzin) | 2.312 kgCO2e/litre | DEFRA 2023 |
Austria has one of the lowest electricity emission factors in the EU — approximately 0.118 kgCO2e/kWh — due to its high share of hydroelectric power (~70% of generation). This means an Austrian SME's Scope 2 footprint is significantly lower than a German or Polish equivalent.
How Austrian SMEs Calculate Their Carbon Footprint: Step by Step
Step 1 — Gather Your Consumption Data (Austria-Specific Documents)
Scope 1 — Direct emissions: - Erdgas rechnung (gas bill from Wien Energie, Energie AG, EVN, or Verbund) — check kWh or m³ total for the year - Heizöl lieferbelege (heating oil delivery notes) — litres delivered - Fuhrparkdaten (fleet vehicle mileage logs or fuel receipts)
Scope 2 — Electricity: - Stromrechnung (electricity invoice) — total kWh per year - Austrian grid factor 0.118 kgCO2e/kWh applies (location-based) - Ökostrom tariff or Herkunftsnachweise (Guarantees of Origin) allow market-based near-zero Scope 2
Scope 3 — Value chain (simplified for SMEs): - Business travel (rail, flights from Vienna, Salzburg, Graz airports) - Employee commuting (Vienna U-Bahn, private car commuting are common) - Waste (Restmüll, Altpapier, Gelber Sack — use Austrian waste emission factors)
Step 2 — Apply Emission Factors
Example — Austrian manufacturing SME, 45 employees:
| Source | Consumption | Factor | tCO2e |
|---|---|---|---|
| --- | --- | --- | --- |
| Natural gas (heating) | 85,000 m³ | 2.204 kg/m³ | 187.3 |
| Fleet diesel (3 vans) | 28,000 litres | 2.683 kg/l | 75.1 |
| Electricity | 320,000 kWh | 0.118 kg/kWh | 37.8 |
| Business travel | 45,000 km | mixed | 8.4 |
| Commuting (45 staff) | estimated | mixed | 22.1 |
| Total | 330.7 tCO2e |
Per employee: 7.3 tCO2e — well above Austrian office-sector benchmarks (2–4 tCO2e/employee) due to manufacturing gas use.
What Austrian Large Companies Are Asking For
Austrian corporates with active supply chain carbon data programmes in 2026 include: - Verbund — energy infrastructure supply chain - ÖBB — railway and logistics suppliers - Raiffeisen — agricultural and manufacturing supply chain - Andritz AG — engineering supply chain - Kapsch — technology supply chain - Austrian Airlines/Lufthansa Group — fuel and catering suppliers
If you supply any of these companies, expect a sustainability questionnaire in 2025–2026 asking for your GHG Protocol-compliant Scope 1, 2, and 3 totals.

Frequently Asked Questions
What carbon reporting law applies to Austrian SMEs?
Austrian SMEs are not directly required to report carbon emissions under NaDiVeG (Austria's Non-Financial Reporting Directive law) unless they are large public-interest entities with 500+ employees. However, Austrian SMEs are significantly affected by CSRD — large Austrian companies (250+ employees from 2025 reporting) must collect Scope 3 Category 1 data from their suppliers. This supply chain pressure means most Austrian SMEs with large corporate customers will receive carbon data requests by 2026.
What is the Austrian electricity emission factor for carbon calculations?
The Austrian national electricity grid emission factor is approximately 0.118 kgCO2e/kWh — one of the lowest in the EU. This low factor reflects Austria's high share of hydroelectric power generation, which makes up approximately 70% of Austrian electricity. Austrian SMEs using Ökostrom (green electricity) tariffs with Herkunftsnachweise (Guarantees of Origin) can claim market-based Scope 2 emissions of near-zero.
Which Austrian companies are asking suppliers for carbon data?
Austrian companies with active supplier carbon data programmes include Verbund (energy infrastructure), ÖBB (railway and transport), Raiffeisen (agriculture and manufacturing), Andritz AG (engineering), Kapsch (technology), and Austrian Airlines (Lufthansa Group). Austrian food exporters supplying German retailers (REWE, Edeka, Lidl) also face carbon data requests through German retail sustainability programmes.
Does Austria have its own carbon tax or ETS?
Austria participates in the EU Emissions Trading System (EU ETS) for large industrial installations emitting 25,000+ tCO2e/year. From 2027, Austria's heating fuel and transport fuel distributors will be covered by EU ETS2 — which will embed a carbon cost into natural gas and diesel prices. Austria does not have a separate national carbon tax above EU ETS obligations. The CO2 component in Austrian energy prices reflects EU ETS pass-through costs.
How do Austrian SMEs use DeCarbonOPS for CSRD supplier questionnaires?
Austrian SMEs enter their Erdgas (m³ or kWh), Strom (kWh), and Diesel (litres) consumption data into DeCarbonOPS. The platform applies Austrian-specific emission factors — including the 0.118 kgCO2e/kWh Austrian electricity factor — and produces a GHG Protocol-compliant Scope 1, 2, and 3 Carbon Passport. The Carbon Passport provides a permanent verification URL accepted by Austrian, German, Swiss, and all EU CSRD procurement portals. The first annual report is free.
