What Should SMEs Do When Customers Ask for ESG Data?

A larger customer sends you a supplier questionnaire. It asks about energy use, emissions, labour practices, waste, governance, certifications, and sustainability policies.

For many SMEs, this is the moment when ESG stops being an abstract concept and becomes a practical business issue. The problem is not always a lack of willingness. The real problem is that the data is often scattered across invoices, spreadsheets, emails, accounting records, HR files, and operational documents.

If your business is starting to receive ESG data requests, the best response is not to panic or rush into writing a polished sustainability report. The better first step is to understand what data you already have, what is missing, and how to organize it in a way that can be reused.

Why ESG data requests are increasing

Large companies are under growing pressure from customers, investors, lenders, procurement teams, and sustainability regulations. Many of them need information from their suppliers to understand risks and impacts across their value chains.

This means SMEs may be affected even when they are not directly required to produce a formal sustainability report. A manufacturer, food processor, exporter, packaging supplier, logistics provider, or professional service company may all be asked to provide sustainability-related information as part of procurement or supplier review.

The request may come in different forms:

• A supplier ESG questionnaire
• A code of conduct assessment
• A carbon footprint data request
• A request for environmental or labour-related policies
• A procurement checklist
• A financing or lender due diligence form
• A sustainability scorecard from a major customer

The important point is simple: ESG data is becoming part of normal business communication.

Do not start with a beautiful report

Many SMEs think the first step is to create a sustainability report. That is understandable, but it is often the wrong starting point.

A report is only useful if the underlying data is clear, consistent, and traceable. Without reliable data, the report becomes difficult to update and risky to share.

Before writing a report, SMEs should ask:

• What ESG data do we already collect?
• Where is the data stored?
• Who owns the data internally?
• Can we explain where the numbers come from?
• Can we update the data regularly?
• Can we reuse the same data for different customer requests?

A practical ESG system starts with data readiness, not design.

What data should SMEs prepare first?

SMEs do not need to collect everything at once. A good starting point is to focus on basic information that customers commonly request.

Environmental data

This may include:

• Electricity consumption
• Fuel use
• Water use
• Waste generation
• Recycling practices
• Materials used in production
• Packaging information
• Basic emissions-related data

The goal is not perfection from day one. The goal is to create a clear starting point.

Social data

This may include:

• Number of employees
• Workplace safety records
• Training activities
• Labour policies
• Working conditions
• Diversity-related information where relevant and appropriate
• Supplier or contractor practices

For SMEs, social data often already exists in HR, payroll, or operations records. The challenge is making it usable.

Governance data

This may include:

• Business ethics policies
• Anti-corruption policy
• Supplier code of conduct
• Data protection practices
• Complaint or grievance processes
• Responsibility for ESG topics inside the company

Governance is often overlooked by SMEs, but it is important because it shows how the business is managed.

Common mistakes to avoid

Mistake 1: Answering every request manually

When ESG requests arrive, many teams copy and paste answers from old files. This may work once, but it quickly becomes messy when multiple customers ask similar questions in different formats.

A better approach is to build a reusable ESG data base that can support different questionnaires and reports.

Mistake 2: Making claims without evidence

Statements such as “we are sustainable” or “we care about the environment” are not enough. Customers increasingly want evidence.

Evidence may include policies, records, invoices, meter readings, certificates, training logs, or documented procedures.

Mistake 3: Treating ESG as only a compliance issue

ESG data is not only about regulation. It can also support better operations, lower risk, stronger customer relationships, and clearer decision-making.

Mistake 4: Waiting until the deadline is close

If a customer gives you two weeks to submit ESG information, it is already late. Preparing early reduces pressure and improves the quality of your response.

How SMEs can start

A practical starting process can be simple:

1. List the ESG questions you have already received from customers.
2. Group them into environmental, social, and governance topics.
3. Identify which data already exists inside the business.
4. Assign an owner for each data area.
5. Store the information in one structured place.
6. Review the data regularly.
7. Prepare standard answers for repeated customer questions.

This does not require a large sustainability department. It requires structure.
