Measuring your carbon footprint is step one. Reducing it is step two — and it is where CSRD reporting becomes genuinely valuable rather than just a compliance exercise.
The good news for EU SMBs: the highest-impact actions are often the lowest-cost ones. You do not need a sustainability team or a large capital budget. You need to know where your emissions actually come from — and then address the biggest sources first.
This guide covers 10 practical steps, ordered roughly from highest to lowest typical impact for a European SMB.
First: Know Where Your Emissions Come From
Before reducing anything, calculate your Scope 1, 2, and 3 baseline using the EmissionPlan free calculator. Reduction without measurement is guesswork. Once you have your breakdown by scope and category, the high-impact actions become obvious.
Step 1 — Switch to a Renewable Electricity Tariff
Typical saving: 40–100% of Scope 2 emissions · Cost: €0–€50/month premium
For most office-based businesses, Scope 2 (purchased electricity) represents 20–40% of total emissions. Switching to a certified renewable electricity tariff eliminates this entirely under the market-based accounting method — and in most EU countries costs only marginally more than a standard tariff.
Look for tariffs backed by Guarantees of Origin (GOs)— the EU's certification for renewable electricity. Green tariffs without GOs are marketing, not measurement.
Example: A 20-person office in Germany using 24,000 kWh/year produces 8.7 tCO₂e from electricity. Switching to certified renewables reduces this to zero — the single largest reduction available to most SMBs.
Step 2 — Replace Gas Heating with a Heat Pump
Typical saving: 60–80% of heating emissions · Cost: €8,000–€20,000 (significant grants available)
Natural gas is the largest Scope 1 source for most office and light industrial businesses. Air-source heat pumps produce the same heat using 3–4× less energy — and that energy is electricity, which can come from renewables.
EU member states offer substantial heat pump grants under national energy efficiency schemes. Germany's BEG scheme covers up to 70% of costs. Netherlands, France, and Austria have similar programmes. The payback period after grants is typically 4–8 years.
Step 3 — LED Lighting Upgrade
Typical saving: 5–15% of electricity consumption · Cost: €1,000–€5,000 for a full office
If your premises still use fluorescent or halogen lighting, a full LED replacement cuts lighting energy by 50–70%. For a typical 500m² office, this reduces electricity consumption by 3,000–6,000 kWh per year — roughly 1–2 tCO₂e in Germany.
Payback period is usually 2–4 years without grants. Many EU countries offer small business energy efficiency grants that can reduce payback to under 12 months.
Step 4 — Electrify Your Vehicle Fleet
Typical saving: 60–80% of fleet emissions · Cost: €5,000–€15,000 premium per vehicle (grants available)
For logistics, trades, and field service businesses, the vehicle fleet is often the largest single emission source. Replacing diesel vans with electric equivalents reduces per-km emissions by 60–80% depending on your country's grid mix.
In France (nuclear grid, 0.052 kgCO₂e/kWh) the saving is over 90%. In Poland (coal-heavy, 0.742 kgCO₂e/kWh) it is closer to 40% — still significant and improving annually as the grid decarbonises.
EU grants for commercial EVs are available in most member states. Check your national business support agency for current schemes.
Step 5 — Reduce Business Flights
Typical saving: 10–40% of Scope 3 emissions · Cost: €0 (often saves money)
Business travel — particularly long-haul flights — is frequently the largest Scope 3 category for service businesses. A single return London–New York flight produces approximately 1,050 kgCO₂e — equivalent to 3 months of office electricity for a 10-person team.
Practical steps:
- Set a company policy requiring video calls as default for internal meetings
- Replace short-haul flights with train travel where journey time is under 4 hours (Paris–Amsterdam, Frankfurt–Berlin, Brussels–London via Eurostar)
- Consolidate necessary travel — two people attending the same conference, not separately
- Track flight emissions by employee and include in team performance conversations
Step 6 — Improve Building Insulation
Typical saving: 15–30% of heating consumption · Cost: €5,000–€30,000
Poor insulation means your heating system works harder to maintain temperature. Roof insulation, double or triple glazing, and draught-proofing are typically the highest-return insulation investments for commercial properties.
If you lease your premises, negotiate with your landlord — CSRD requirements are creating pressure across the EU for landlords to improve building energy performance. Many EU countries have MEES (Minimum Energy Efficiency Standards) coming into force for commercial lets that make this a shared interest.
Step 7 — Introduce a Commuting Policy
Typical saving: 10–25% of commuting emissions · Cost: €0
Employee commuting is often the second-largest Scope 3 category for office businesses. A structured commuting policy can meaningfully reduce it:
- Remote working: 2 days/week remote reduces commuting emissions by 40%
- Cycle-to-work schemes: subsidised bike purchase incentivises cycling
- Public transit subsidies: covering or subsidising transit passes shifts employees from car to bus or train
- Car-share coordination: matching employees who live near each other
Surveys show that 60–70% of office employees would switch to lower-emission commuting if their employer actively supported it. The barrier is usually inertia, not preference.
Step 8 — Reduce and Divert Waste from Landfill
Typical saving: 3–8% of Scope 3 emissions · Cost: €0–€500/year
General waste going to landfill produces methane as it decomposes — a greenhouse gas with 28× the warming impact of CO₂ over 100 years. The emission factor for landfill waste is 0.444 kgCO₂e/kg, versus 0.021 kgCO₂e/kg for recycled waste.
Simple actions:
- Set up clearly labelled recycling stations (general, paper, plastic, glass)
- Switch to a composting contractor for food waste if you have a kitchen
- Track waste by weight quarterly — many waste contractors will provide reports
Step 9 — Smart Building Controls and Energy Monitoring
Typical saving: 10–20% of energy consumption · Cost: €500–€3,000
Smart thermostats, occupancy-based lighting, and real-time energy monitoring consistently reduce energy waste in commercial buildings by 10–20% without any behaviour change from staff.
Simple examples: a smart thermostat that reduces heating by 2°C overnight saves approximately 8–12% of heating energy. Occupancy sensors that turn off lights in unused meeting rooms save 15–25% of lighting energy in typical offices.
Step 10 — Engage Your Supply Chain
Typical saving: Varies widely · Cost: €0 (relationship-based)
For businesses with significant purchased goods and services, engaging key suppliers on their own carbon footprint can reduce your Scope 3 significantly over time. This does not require auditing your supply chain — it starts with a simple request: “Do you have a carbon footprint report?”
Sharing your own EmissionPlan report with suppliers signals that you take this seriously and creates reciprocal pressure. Many large EU businesses now include carbon reporting as a supplier pre-qualification criterion — this will increasingly trickle down to SMBs.
Prioritising Your Actions
The right order depends on your footprint breakdown. After calculating with EmissionPlan, rank your categories by tCO₂e and address the top two or three first. For most EU SMBs:
- Office-based: renewable electricity → flight reduction → commuting policy
- Logistics/trades: fleet electrification → routing efficiency → depot energy
- Manufacturing: process heating → renewable electricity → fleet
- Retail: renewable electricity → refrigeration efficiency → waste
Year-over-year reduction is what auditors and investors actually want to see — not a perfect number, but a consistent downward trend with credible actions behind it. Start measuring now, act on the biggest sources, and report the progress annually.
