SMEs generate roughly 60% of European business emissions and are the largest single component of most banks' financed emissions. Pressure is coming from three directions at once: large customers cascading Scope 3 requirements, banks originating SLLs and green loans, and regulation via CSRD supply-chain reach.
Yet most SMEs have no dedicated sustainability team. This guide sets out a pragmatic six-step approach that fits within existing finance and operations functions.
Step 1 — Build a first footprint
Aim for materiality, not perfection:
- Scope 1 — collect fuel bills (gas, diesel, LPG), refrigerant service records.
- Scope 2 — electricity consumption from utility bills; use both location- and market-based.
- Scope 3 — start with spend-based screening across all 15 categories, then focus on the material 2–3.
Software like Redigo Carbon collapses this from weeks of consulting into days of self-service.
Step 2 — Set a credible target
Options for SMEs:
- SBTi SME Target — a streamlined route with pre-set 1.5°C aligned targets (42% Scope 1+2 reduction by 2030 vs base year).
- Customer-mandated — where an anchor customer requires an SBTi-validated target.
- Bank-mandated — where an SLL is being originated.
Step 3 — Build a shortlist of actions
The MACC for a typical SME will feature:
- Lighting (LED + controls).
- Heating (heat pump replacement of gas boilers).
- Fleet (light-vehicle electrification).
- On-site solar where feasible.
- Renewable electricity tariff.
- Refrigerant transition where applicable.
Sequenced by payback and cost per tCO₂e avoided.
Step 4 — Finance the plan
- Green Loans for eligible CapEx.
- SLLs — simplified structures now available at most EU banks; the Redigo Carbon platform is designed to make these viable at SME scale.
- Public grants and subsidies — national schemes (BAFA, FGaz, ADEME, etc.).
- ESCO / EPC models for energy efficiency, off-balance-sheet.
Step 5 — Execute and measure
Automate data ingestion where possible — utility bills, telematics, refrigerant service. Report progress at least annually.
Step 6 — Respond to customer and bank requests
Once the footprint and plan exist, filling in supplier questionnaires (EcoVadis, CDP Supply Chain, custom bank forms) becomes a matter of extracting data — not months of consulting.
What SMEs typically get wrong
- Over-engineering the first measurement. Ship a 70%-accurate footprint fast; refine later.
- Ignoring Scope 3. Even without formal reporting, customers ask.
- No governance. Assign an owner — usually the CFO — at the start.

Frequently asked questions
Is CSRD applicable to SMEs?+
Listed SMEs are in scope from FY2026 (with a two-year opt-out). Unlisted SMEs are not directly in scope but are affected via supply-chain reach from larger CSRD-reporting customers.
How long does a first SME footprint take?+
With a modern platform, 2–6 weeks from data collection to first inventory. Consulting-heavy approaches typically take 3–6 months.
What's the minimum credible target for an SME?+
SBTi SME Target: 42% Scope 1+2 reduction by 2030 vs a 2019–2022 base year, plus a commitment to measure and reduce Scope 3.
