ESG Assessment Methodology

Understand how mature your company truly is with ESG.

The ZEROvia ESG Assessment helps SMEs better assess their own ESG maturity: in a structured, understandable way and with reliable evidence.
Each assessment question is answered on five levels. This way, you not only see if a topic is met, but also how far along your company is, where gaps exist, and what next steps are sensible.

This is not an external black-box rating. It is an operational assessment that helps you better answer ESG requirements from customers, banks, and supply chain partners, and to strategically advance sustainability within your company.

Start ESG Assessment On Methodology

Our 5 Principles

An assessment must provide direction, not just evaluate.

Maturity level instead of yes/no

Each assessment question is answered on a five-point scale. This creates a differentiated picture: from initial approaches to proven, established processes.

Evidence before assertions

Answers gain value when they are linked to documents, data sources, policies, SOPs, or other evidence.

Operationally usable

The assessment not only shows a status, but also helps to derive gaps, measures, and next steps.

CSRD-compliant

The assessment is aligned with VS/VSME and supports ESG inquiries from large customers subject to CSRD.

Controlled divisibility

The company decides which results remain publicly visible, privately shareable, or for internal use only.

Maturity stages

Four stages from the initial check to the complete VS/VSME report.

ESG Quick Check

Initial situation assessment with a few questions. Ideal for gaining a quick overview.

ESG Assessment

50 questions with five response levels and optional evidence. Helps to more accurately assess one's own ESG maturity.

VS/VSME Basic

Structured ESG data along the de facto standard for SME data exchange to large companies subject to CSRD.

VS/VSME Comprehensive

Detailed information on strategy, goals, measures, risks, and supply chain.

The ESG assessment bridges the gap between a quick self-assessment and a robust VS/VSME data foundation. It makes visible where substance already exists and where further data, evidence, or measures are sensible.

Test depth

Clearly indicate how an ESG profile was created.

Profile Type	Meaning	Typical use
Self-declared	The information was recorded and released by the company itself.	Onboarding, public ESG profile, initial customer communication.
Checked by ZEROvia	ZEROvia checks the plausibility, completeness, and consistency of the information.	Customer inquiries, bank discussions, ESG data packs.
Validated by partners	An external partner will verify selected information or documents.	Audits, critical supplier relationships, increased requirements.

Proof

What evidence makes an assessment stronger.

An ESG assessment becomes more robust when statements are not just claimed but backed up with appropriate evidence.

Typical evidence includes:

Policies and internal guidelines
SOPs and Process Descriptions
Certificates
Invoices and consumption data
CO2/GHG Data
HR and Occupational Safety Data
Supplier acknowledgments
Audit reports
Management approvals

AI helps with structuring. Responsibility remains with the company.

ZEROvia uses AI to read documents, suggest data, match evidence, and highlight gaps.

However, AI does not replace corporate responsibility, external auditing, or legal advice. Before information is used in a public profile, report, ESG assessment, or data pack, human approval is required.
