How to Engage Your Suppliers in an ESG Strategy

Many companies start their ESG journey by focusing on their own operations: energy consumption, internal policies and employee wellbeing.

But one reality quickly emerges. A large share of a company's impact sits in its value chain.

Suppliers, subcontractors and partners often represent a major part of environmental and social risks.

For sustainability managers across Belgium and Europe, engaging suppliers is therefore becoming a central pillar of ESG strategies.

And increasingly, it's good practice and also expected in frameworks such as EcoVadis, B Corp or ESG reporting standards.

Companies should involve their suppliers in a structured and realistic way.

Why Supplier Engagement is Becoming Critical for ESG

Improving your ESG performance cannot stop at your own organisation.

A company that wants to build a credible sustainability strategy must also understand:

• the environmental practices of its suppliers
• social and labour conditions in the value chain
• governance standards among partners

In other words, ESG increasingly means managing the entire ecosystem around your business.

This is also where financial implications appear.

Banks, investors and major clients increasingly want to understand how companies manage ESG risks in their supply chain.

In many industries, the majority of ESG risks and impacts sit in the value chain rather than in direct operations.

Want to structure your supplier ESG approach?

Let's discuss how to build a practical and scalable strategy for your suppliers.

How We Help Companies Throughout This Process

At ESGlogic, our objective is to initiate a simple and structured ESG supplier assessment process, designed to identify key suppliers and lay the groundwork for a responsible approach.

We do that through 4 stages.

1. Map Priority Suppliers

Identify key suppliers using a supplier analysis table to focus efforts where it matters most.

2. Set a Clear ESG Framework

Define expectations through a supplier code of conduct covering environmental, social and governance topics.

3. Assess ESG Maturity

Evaluate suppliers consistently using a standardised ESG questionnaire to identify risks and gaps.

For companies looking to go further, a more advanced and structured approach exists through the VSME Medals framework.

4. Structure the Approach

Consolidate insights into a clear results synthesis to define priorities and next steps.

The expected results

This approach enables companies to quickly achieve:

• a clear view of their supplier ecosystem
• a comparable assessment of the ESG maturity of suppliers
• a shared framework of good practices with suppliers
• a solid foundation to scale the approach over time

Using the VSME Medals to Assess Supplier ESG Maturity

An effective way to structure supplier ESG engagement is to rely on the framework behind the VSME Medals.

The VSME Medals are designed to evaluate the ESG maturity level of companies, including suppliers, based on a structured set of criteria.

Each level, Bronze, Silver, Gold, Platinum corresponds to a progressive level of ESG practices implemented.

This makes the framework particularly useful for supplier engagement.

Instead of asking generic questions, companies can:

• assess where each supplier stands in terms of ESG maturity
• compare suppliers on a consistent basis
• identify what is missing to reach the next level

It transforms supplier engagement from a simple data collection exercise into a clear progression path.

Why Engaging Suppliers Is Also a Strategic Advantage

Beyond compliance and ratings, supplier engagement can generate real strategic benefits.

Companies that structure their supply chain ESG approach often gain:

• better resilience in their value chain
• improved credibility with investors and banks
• stronger ESG ratings
• improved client trust

And one key question remains.

If your suppliers represent most of your impact, can your ESG strategy really be credible without them?
