Many SMEs hear about CSRD and assume it only matters to large companies.

That assumption is only partly correct.

Many SMEs may not be directly required to report under CSRD. However, they can still be affected indirectly when larger customers, investors, lenders, or procurement teams ask for sustainability-related data from suppliers and business partners.

For SMEs, the practical question is not only “Are we directly covered by CSRD?”

A better question is: “Will our customers ask us for ESG data because they need it for their own reporting and risk management?”

What CSRD means in practical terms

CSRD stands for Corporate Sustainability Reporting Directive. It is part of the European sustainability reporting landscape and is connected to the European Sustainability Reporting Standards, known as ESRS.

For SMEs, the technical details can feel overwhelming. But the practical implication is easier to understand:

Large companies need better sustainability information. To get that information, they often need data from their value chains.

That value chain may include suppliers, manufacturers, processors, logistics companies, service providers, distributors, and exporters.

This is where SMEs enter the picture.

Direct impact vs indirect impact

It is important to separate direct and indirect impact.

Direct impact

A company is directly affected when it falls within the reporting requirements and must prepare sustainability disclosures itself.

Not every SME falls into this category.

Indirect impact

A company is indirectly affected when another organization asks it to provide sustainability data, policies, evidence, or operational information.

This can happen because the larger customer needs to understand its own value-chain impacts, risks, or procurement standards.

For many SMEs, indirect impact is the more immediate issue.

What customers may ask for

A larger customer may ask an SME to provide information about:

Energy consumption
Greenhouse gas emissions-related data
Water use
Waste management
Packaging materials
Labour practices
Health and safety
Human rights policies
Supplier standards
Anti-corruption controls
Certifications
Sustainability targets or actions

These requests may not always use the words CSRD or ESRS. They may appear as supplier questionnaires, procurement forms, onboarding requirements, tender documents, or annual supplier reviews.

Why SMEs should not ignore this

Some SMEs may think, “We are too small. This does not apply to us.”

That response can be risky.

Even if a business is not directly required to report, ESG data can still affect commercial relationships. Customers may prefer suppliers who can provide clear, timely, and credible information.

In some industries, ESG readiness may gradually become part of supplier selection, contract renewal, or financing discussions.

This does not mean SMEs need to become sustainability experts overnight. It means they should prepare a basic data foundation before requests become urgent.

What SMEs should prepare now

A practical first step is to build an ESG data inventory.

This can include:

Environmental data

Electricity and fuel use
Water use
Waste and recycling
Materials and packaging
Transport or logistics-related data where relevant

Employee information
Health and safety records
Training records
Labour policies
Supplier or contractor practices

Governance data

Code of conduct
Anti-corruption policy
Data protection practices
Responsibility for sustainability topics
Supplier requirements or procurement standards

The aim is to know what data exists, where it is stored, and who is responsible for maintaining it.

Common mistakes SMEs make

Waiting until a customer asks

By the time a customer sends a questionnaire, the deadline may be short. Preparing early gives the business more control.

Treating each request as a separate task

If every customer request is handled manually, the workload grows quickly. A structured ESG data base helps SMEs reuse information.

Making broad claims without evidence

Customers increasingly expect evidence behind sustainability statements. Policies, records, invoices, procedures, and documented actions matter.

Assuming compliance language is enough

It is not enough to say the business “supports sustainability.” Customers often need specific data points and clear explanations.
