VSME Basic Module Fields: B1-B11 Data Points Explained

Field-by-field checklist for the EFRAG VSME Basic Module: required B1-B11 data points, optional fields, Scope 1 and 2 inputs, and what to collect before reporting.

The VSME Basic Module is the core of the EFRAG Voluntary Sustainability Reporting Standard for SMEs. It covers disclosures B1 to B11 and roughly 46 datapoints across general information, environment, workforce, and business conduct.

Use this page as the field checklist: what each VSME Basic Module data point means, whether it is required, and what source document usually proves it. If you need the reporting workflow instead, use the step-by-step VSME Basic Module guide. If you are comparing routes, see Excel template vs QuickVSME vs consultants vs software.

Overview

Of the roughly 46 VSME Basic Module datapoints:

  • 27 are mandatory for all companies using the standard
  • 15 are conditional ("if applicable" — only fill if relevant to your business)
  • 4 are voluntary (useful, but not expected from every SME)

The Basic Module does not require Scope 3 emissions, a materiality assessment, or a climate strategy. Those are part of the optional Comprehensive Module (C1–C9).

B1 — Basis for Preparation

Purpose: Identify the reporting entity and set the context.

FieldRequiredNotes
Legal nameYesAs registered
Legal formYese.g., GmbH, AG, Einzelfirma
Registered addressYes
TurnoverYesAnnual revenue in reporting currency
Total assets (balance sheet)YesEnd-of-year figure
NACE codeYesEconomic activity classification (eurostat)
Number of employeesYesHeadcount at year-end
Reporting periodYesTypically the financial year
Location of operationsConditionalLatitude/longitude if multiple sites

B2 — Practices, Policies, and Future Initiatives

Purpose: Describe what sustainability measures the company has in place.

FieldRequiredNotes
Sustainability practices descriptionYesBrief narrative
Written sustainability policyYesYes/No — does one exist?
Reduction targets definedYesYes/No — any quantitative targets?
Future initiatives plannedVoluntaryWhat's planned but not yet started

This section is intentionally qualitative. A one-paragraph description is sufficient.

B3 — Energy and Greenhouse Gas Emissions

Purpose: Quantify energy consumption and resulting emissions.

FieldRequiredUnitNotes
Total energy consumptionYesMWh or kWhSum of all energy sources
Electricity consumptionYeskWhGrid electricity
Heating oilConditionalLitresIf used
Natural gasConditionalkWhIf used
Diesel (fleet)ConditionalLitresCompany vehicles
Petrol (fleet)ConditionalLitresCompany vehicles
Renewable energy shareVoluntary%Portion from renewable sources
Scope 1 GHG emissionsYestCO2eDirect emissions (heating, vehicles)
Scope 2 GHG emissionsYestCO2eFrom purchased electricity
GHG intensity ratioYestCO2e / turnoverEmissions per unit of revenue

Scope 3 is NOT required in the Basic Module. This is a common misconception — Scope 3 (supply chain emissions) is only part of the Comprehensive Module (C3).

Emission factors

For Swiss companies, GHG calculations typically use:

  • KBOB factors (version 8.02, 2009/1:2022) for building-sector emissions — kbob.admin.ch
  • BAFU / ecoinvent factors for general corporate emissions
  • GHG Protocol methodology for calculation structure

QuickVSME uses KBOB lifecycle emission factors for the following conversions:

  • Electricity: 0.128 kg CO2e/kWh
  • Heating oil: 3.24 kg CO2e/litre
  • Natural gas: 0.228 kg CO2e/kWh
  • Diesel: 3.24 kg CO2e/litre
  • Petrol: 3.21 kg CO2e/litre

B4 — Pollution of Air, Water, and Soil

Purpose: Disclose significant pollution and regulatory obligations.

FieldRequiredNotes
Subject to PRTR reportingYesYes/No — Pollutant Release and Transfer Register
Pollutant releasesConditionalOnly if legally required to report

Most service-sector SMEs will answer "No" to both.

B5 — Biodiversity

Purpose: Flag proximity to protected areas.

FieldRequiredNotes
Operations near biodiversity-sensitive areasYesYes/No — Natura 2000 or equivalent protected zones
Mitigation actionsConditionalOnly if "Yes" above

B6 — Water

Purpose: Basic water usage data.

FieldRequiredUnitNotes
Total water withdrawalYesFrom water bills
Total water consumptionConditionalIf different from withdrawal

B7 — Resource Use, Circular Economy, and Waste

Purpose: Waste generation and recycling performance.

FieldRequiredUnitNotes
Total waste generatedYesTonnesAnnual total
Hazardous wasteYesTonnesSubset of total
Non-hazardous wasteYesTonnesSubset of total
Waste diverted to recycling/reuseYesTonnes
Circular economy initiativesVoluntaryNarrativeOptional description

Validation: Hazardous + non-hazardous must equal total. Recycled waste must be ≤ total.

B8 — Workforce: General Characteristics

Purpose: Basic workforce demographics.

FieldRequiredNotes
Total employees (headcount)YesEnd of reporting period
Gender distributionYesMale / Female / Other
Permanent contractsYesCount
Temporary contractsYesCount
Full-time vs part-timeConditionalIf tracked
Geographic distributionConditionalIf multiple locations

B9 — Workforce: Health and Safety

Purpose: Work-related incidents.

FieldRequiredNotes
Work-related accidentsYesReportable incidents count
FatalitiesYesWork-related deaths
H&S management measuresVoluntaryDescription of safety systems

B10 — Workforce: Remuneration, Collective Bargaining, and Training

Purpose: Fair employment practices.

FieldRequiredNotes
Pays above minimum wageYesYes/No confirmation
Gender pay gapVoluntaryPercentage if tracked
CBA coverageYes% of employees under collective agreements
Average training hoursYesHours per employee per year

B11 — Convictions and Fines for Corruption and Bribery

Purpose: Governance transparency.

FieldRequiredNotes
Corruption convictionsYesCount in reporting period
Corruption/bribery finesYesTotal amount in reporting currency

Most SMEs will report zero for both. That's fine — the point is transparency.

Basic vs Comprehensive

Basic ModuleComprehensive Module
Datapoints~46~100 additional
Scope 3 emissionsNot requiredRequired (C3)
Materiality assessmentNot requiredRequired (C2)
Climate strategy & targetsNot requiredRequired (C1, C3)
Human rights due diligenceNot requiredRequired (C6, C7)
Can stand aloneYesNo — requires Basic first
Target userAny SMESMEs with investor/bank reporting needs

Start with Basic. Only add Comprehensive if a specific stakeholder requests it.

How long does it take?

With the data at hand (energy bills, HR records, waste disposal records), filling out the VSME Basic Module takes 30–60 minutes using a guided tool like QuickVSME.

Without a tool, working from the raw EFRAG template (Excel/XBRL format), expect 2–4 hours for the first report. For the sequence of work, use the step-by-step workflow guide.

FAQ

How many fields are in the VSME Basic Module?

The Basic Module contains disclosures B1 to B11 and roughly 46 datapoints. Not every datapoint is mandatory for every company: some are conditional and only apply if the activity, location, or data point is relevant.

Is Scope 3 required in the VSME Basic Module?

No. Scope 3 emissions are not required in the Basic Module. The Basic Module focuses on Scope 1 and Scope 2 greenhouse gas emissions; Scope 3 is considered under the Comprehensive Module if stakeholders specifically need it.

Should I use this page or the step-by-step guide?

Use this page when you need the exact B1-B11 field list. Use the step-by-step guide when you are ready to gather documents, enter data, validate the report, and generate the declaration.
