Scope 3 emissions: understand and manage the largest part of your carbon footprint
The Greenhouse Gas Protocol defines 15 categories for Scope 3 emissions. Depending on your industry and business model, they typically account for the majority of total emissions – yet they are still frequently overlooked.
Current trend: VSME becomes the new benchmark
NEW The recent CSRD Omnibus reform raised the thresholds significantly – many SMEs are no longer in formal scope. As a result, the VSME standard is becoming the pragmatic framework for voluntary but market‑relevant ESG reporting.
IMPORTANT If you want to secure financing, win large customers or attract investors, you still need a consistent view on Scope 3 emissions – even without a legal mandate. The Quick Check helps you build that foundation and generate VSME‑compatible data points.
The Scope 3 Materiality Quick Check: identify your hotspots in minutes
The Quick Check identifies the most material Scope 3 categories for your company – tailored to your industry, VSME‑compatible and directly connected to your double materiality analysis.
✅ What the Quick Check delivers:
- Materiality matrix: Positioning all 15 categories by relevance and level of control – as a solid starting point for VSME or ESG reporting.
- Sector‑specific weighting: Uses typical profiles for your industry instead of generic, one‑size‑fits‑all lists.
- CO₂e estimates: High‑level order‑of‑magnitude estimates for your Scope 3 emissions to support prioritisation.
- Supplier focus: Highlights the supplier clusters that matter most for your engagement programme.
- VSME‑readiness check: Initial alignment with the key climate and emissions indicators in the VSME standard.
⚠️ Important note:
The Quick Check is an orientation tool. It does not replace a full GHG inventory or an audit‑ready report. It shows you where to start – not what your final, fully assured numbers will look like.
The 15 Scope 3 categories: where your emissions occur
Upstream emissions
These categories cover all emissions generated before your own operations:
📦 Category 1: Purchased goods & services
In many sectors the single most important Scope 3 category.
- Raw materials and components
- External services
- Packaging materials
🏭 Category 2: Capital goods
Long‑lived investments:
- Machinery and equipment
- Buildings and infrastructure
- IT equipment
⚡ Category 3: Fuel‑ and energy‑related
Upstream emissions of your Scope 1 and 2:
- Extraction and refining
- Grid losses
- Fuel transport
🚚 Categories 4–8: Transport, waste & mobility
Operational emissions across your value chain:
- Inbound logistics (Cat. 4)
- Waste treatment (Cat. 5)
- Business travel & commuting (Cat. 6–7)
Downstream emissions
These categories cover emissions after your products leave the factory gate:
🔌 Category 11: Use of sold products
Critical for energy‑using products.
- Automotive: use phase dominates lifecycle emissions
- Electronics: electricity consumption over lifetime
- Industrial equipment: operational emissions
💰 Category 15: Investments
Often the key category for financial institutions.
- Financed emissions
- Portfolio footprint
- Lending and investment portfolios
♻️ Category 12: End‑of‑life
Disposal and recycling:
- Landfilling vs. incineration
- Recycling rates
- Circular economy potential
🏪 Other downstream categories
Relevant depending on your business model:
- Distribution (Cat. 9)
- Processing of sold products (Cat. 10)
- Franchises & leased assets (Cat. 13–14)
Sector‑specific Scope 3 patterns
The materiality of Scope 3 categories varies widely by industry. The table summarises typical patterns – not precise percentages.
| Sector | Typical top categories | Scope 3 share |
|---|---|---|
| Automotive | Cat. 11 (use phase), Cat. 1 (purchased goods), Cat. 4 (transport) | almost the entire footprint in Scope 3 |
| Financial services | Cat. 15 (investments), Cat. 1, Cat. 6–7 (travel & commuting) | very high share in Scope 3 |
| Manufacturing | Cat. 1 (purchased goods), Cat. 4 (transport), Cat. 2 (capital goods) | often in the upper range |
| Steel | Cat. 1 (raw materials), Cat. 10–11 (processing & use), Cat. 3 (energy upstream) | very high Scope 3 share |
| IT & software | Cat. 1 (hardware & services), Cat. 11 (use of digital services), Cat. 6–7 | predominantly Scope 3‑driven |
| Retail | Cat. 1 (goods purchased for resale), Cat. 4 & 9 (transport & distribution), Cat. 11 (use) | typically well above half of total emissions |
How the Scope 3 Materiality Quick Check works: 4 simple steps
Basic data
Enter your sector, company size, revenue and business model – this sets the baseline for sector‑specific weighting.
Time: a few minutes
Category check
Quick yes/no questions for all 15 Scope 3 categories – automatically tailored to your sector.
Time: a few minutes
Data quality
Optional: add first activity data or spend figures to refine the estimates where you already have good information.
Time: as needed
Results & roadmap
Materiality matrix, indicative CO₂e figures and clear next steps – ready to feed into VSME reports or investor materials.
Delivery: instant
From materiality analysis to implementation
The Quick Check is your starting point for systematic Scope 3 management. The results support you in:
📊 Strategic prioritisation
- Focusing on the top 3–5 categories
- Balancing quick wins and long‑term levers
- Allocating resources where they matter most
🤝 Supplier engagement
- Identifying the most relevant supplier clusters
- Developing data request templates
- Launching collaborative reduction programmes
🎯 Science Based Targets
- Defining Scope 3 targets where emissions are material
- Progressively meeting SBTi requirements
- Aligning climate ambition and business strategy
📈 VSME & ESG reporting
- Addressing key VSME indicators in a structured way
- Improving data quality over the medium term
- Preparing disclosures for banks and customers
⚠️ Important limitations of the Quick Check
- Not a full inventory: Estimates are based on sector profiles, not your complete primary data set.
- No SBTi validation: Official Science Based Targets require a detailed emissions inventory.
- Not audit‑ready: Assured reports (for large groups, for example) need additional processes and controls.
- No API integration: Data is entered manually, there is no direct ERP or system connection.
Frequently asked questions
What exactly are Scope 3 emissions?
Scope 3 covers all indirect greenhouse gas emissions along your upstream and downstream value chain. Unlike Scope 1 (direct emissions) and Scope 2 (purchased energy), you only have indirect control – yet, for many companies, Scope 3 accounts for by far the largest share of the overall footprint.
Do we still have to report as an SME?
Many SMEs are no longer directly in scope of CSRD after the latest adjustments. However, sustainability reporting still matters – for example, because large customers, banks or investors request structured ESG information or because you want to report voluntarily under VSME. The Quick Check helps you tackle Scope 3 in a pragmatic way without launching a full CSRD project.
How reliable are the Quick Check estimates?
The Quick Check uses sector benchmarks and typical emissions profiles. Results give you a robust first indication and clear priorities but they are not a replacement for a full inventory based on primary data. For VSME reports or SBTi target‑setting, this is a strong starting point – not the final step.
What data do we need for a full Scope 3 inventory?
That depends on your top categories. For Category 1 you need purchasing data and, where possible, supplier‑specific emission factors. For Category 11 you need product use data; for Categories 6–7 you need travel and commuting data. The Quick Check shows which categories are most material – and therefore where detailed data collection will have the biggest impact.
How long does a full Scope 3 inventory take?
In practice, the first full Scope 3 inventory for a mid‑sized company often takes several months, and longer for large groups. Data availability at suppliers and building robust processes are usually the main bottlenecks. By contrast, the Quick Check gives you a well‑founded first orientation and a roadmap within minutes – so you can decide how far you actually want to go.
