Carbon Footprint for Portuguese SMEs: A Complete 2026 Guide
Why Portuguese SMEs Are Receiving Carbon Data Requests
Carbon footprint reporting for Portuguese small businesses is accelerating in 2026. Portugal's CSRD supply chain integration with Spain, Germany, and the UK creates a flow of carbon data requests reaching Portuguese SMEs in manufacturing, tourism, agriculture, and logistics.
Key drivers: - CSRD supply chain reach — Large Portuguese companies (Jerónimo Martins, EDP, Sonae, Galp, TAP) are active CSRD filers with supplier data collection programmes - Tourism sector pressure — Large hotel groups, tour operators (TUI, Thomas Cook, Club Med) and airline suppliers are requesting Scope 3 data from Portuguese accommodation and services suppliers - Agricultural supply chains — Portuguese wine, cork, olive oil, and fruit exporters face carbon data requests from UK, German, and Scandinavian retail buyers
Portuguese Emission Factors: DGEG and IPCC Data
For Portuguese carbon reporting, use emission factors from the Direção Geral de Energia e Geologia (DGEG) for electricity, and standard EU factors for fuel combustion:
| Source | Factor | Unit |
|---|---|---|
| Portugal grid electricity | 0.195 | kgCO2e per kWh |
| Natural gas | 0.204 | kgCO2e per kWh (or 2.35 per m³) |
| Diesel (road) | 2.683 | kgCO2e per litre |
| Petrol | 2.267 | kgCO2e per litre |
| LPG | 1.555 | kgCO2e per litre |
| Portugal average car | 0.155 | kgCO2e per km |
Note: Portugal's electricity grid has been rapidly decarbonising — driven by solar (Portugal had record 100% renewable generation days in 2023 and 2024) and wind power. The grid factor is declining significantly year-on-year. Always use the most recent DGEG published factor for your reporting year.
Worked Example: Portuguese Manufacturing SME
Sample company: A 22-person Setúbal-based packaging manufacturer
Scope 1 — Natural gas: 28,000 m³ × 2.35 = 65,800 kgCO2e = 65.8 tCO2e
Scope 2 — Portuguese electricity: 95,000 kWh × 0.195 = 18,525 kgCO2e = 18.5 tCO2e
Scope 3 — Business travel (Lisbon–Frankfurt × 4 return trips): 1.9 tCO2e
Scope 3 — Commuting (22 staff, Setúbal area): 8.8 tCO2e
Scope 3 — Waste: 2.1 tCO2e
Total: 97.1 tCO2e | Per employee: 4.4 tCO2e/FTE
Portugal's Climate Commitments and Business Impact
Portugal's National Energy and Climate Plan (PNEC 2030) targets 45% renewable energy and 55% GHG reduction by 2030. Portugal achieved 65% renewable electricity generation in 2023, making it one of the EU's leaders in grid decarbonisation.
For Portuguese businesses, the practical implication is that Scope 2 electricity emissions are already low and declining — making Scope 1 gas and Scope 3 value chain the priority reduction targets.

Frequently Asked Questions
What emission factor do Portuguese businesses use for electricity?
Portuguese businesses use the DGEG (Direção Geral de Energia e Geologia) grid emission factor. For 2023–24 reporting: approximately 0.195 kgCO2e per kWh. Portugal's grid is rapidly decarbonising — driven by solar and wind — and the factor is declining annually. Portugal achieved record 100% renewable generation days in 2023 and 2024.
Which large Portuguese companies are collecting supplier carbon data?
Large Portuguese companies with active supplier carbon data programmes include: EDP (Energias de Portugal) — energy sector suppliers; Jerónimo Martins — food and consumer goods suppliers; Galp — oil and gas services chain; Sonae — retail and technology suppliers; and Mota-Engil — construction and infrastructure supply chain. Portuguese wine, cork, and agriculture exporters also receive carbon data requests from UK, German, and Scandinavian retail buyers.
Does Portugal have its own carbon reporting regulation beyond CSRD?
Portugal transposed CSRD into Portuguese law through Decreto-Lei applying to large Portuguese companies from 2025. There is no separate Portuguese SME carbon reporting regulation. Portuguese SMEs are affected primarily through supply chain data requests from CSRD-regulated large companies and export market requirements from UK, EU, and US buyers.
How does Portugal's solar growth affect Scope 2 calculations?
Portugal's rapid solar PV expansion means the national grid emission factor is declining significantly year-on-year. Portuguese businesses that have installed on-site solar panels can claim market-based Scope 2 accounting (near-zero emissions from their own generation) or use Guarantees of Origin (GO) certificates from Portuguese renewable energy suppliers. Contact ERSE (Entidade Reguladora dos Serviços Energéticos) for the most recent published grid factor.
Can Portuguese businesses use a Carbon Passport for EU supplier questionnaires?
Yes. A DeCarbonOPS Carbon Passport uses GHG Protocol methodology — the universal standard accepted across all EU CSRD supply chain questionnaires. Enter your utility data in standard Portuguese units and the platform produces your Scope 1, 2, and 3 totals with a permanent verification URL accepted by Spanish, German, French, UK, and international procurement portals.
