ESG reporting for SMEs in Switzerland: the checklist for an easy start with VSME Basic

How to create your first sustainability report: practical, without Excel chaos.

How to create your first sustainability report: practical, without Excel chaos, and based on the VSME standard.

Many Swiss companies feel the pressure: not because Brussels suddenly governs Switzerland, but because the market is creating facts. German large customers, international supply chains and increasingly Swiss banks too are asking for a sustainability report for SMEs, often in formats designed for corporations.

This is where ESG reporting under the VSME standard offers a chance. It is the lowest common denominator that European business accepts. For Swiss companies, it is above all one thing: a "travel adapter" for data flows. The best part: the standard was developed specifically for SMEs and follows the principle of "accepting gaps" (if applicable).

The most important principle: "If applicable"

Before you collect data, good news: the VSME asks for flexibility, not perfection. The "if applicable" principle means you only need to report information if it applies to your company.

  • No production with high water consumption? Then the water module does not apply.
  • Fewer than 50 employees? Many social metrics fall away.

With this pragmatic approach, we go through the checklist for the Basic module.

1. The basis: company profile

The VSME Basic module starts gently but requires precision. This prevents your company from being measured against large-corporation benchmarks by mistake.

What you should have ready:

  • Short strategy statement: do you have sustainability goals? (A simple yes/no is often enough.)
  • Headcount: total number of employees and full-time equivalents (FTE).
  • Financial figures: total assets and net revenue.

2. Environment: energy & emissions

The goal is to calculate emissions (Scope 1 & 2). Don't worry: you provide the consumption data, ZEROvia does the calculations.

Find the following invoices:

  • Electricity: total consumption in kWh.
  • Fuels: consumption of gas, oil or wood (heating/process heat).
  • Vehicle fleet: fuel consumption (diesel/petrol in litres).

3. Social: the workforce

Here the VSME follows European standards, but thanks to the thresholds for Swiss SMEs it is quite manageable.

The following data points are requested:

  • Gender distribution: number of women/men.
  • Occupational safety: number of accidents (data source: SUVA statement).
  • Wages: is an adequate wage paid?

4. Governance: clean business

Unlike corporate reports, the Basic module focuses on one hard indicator:

  • Convictions/fines: were there any convictions for corruption in the reporting year?

Conclusion: use the data you already have

The data for simple ESG reporting is already available at 90% of Swiss SMEs. Thanks to the "if applicable" principle, you don't need to fear empty fields. Doing this considerably strengthens your negotiating position with banks.Outlook: Is the basic module not enough because large customers are asking about the supply chain?
