Double Materiality for SMEs: A Practical Explanation Without Jargon

~5 min read

Double materiality is often discussed in sustainability reporting, especially in relation to European sustainability standards. But for many SMEs, the term sounds technical and difficult.

It does not need to be.

At a practical level, double materiality helps a company look at sustainability from two directions:

  1. How the business affects people, the environment, and society

  2. How sustainability issues affect the business financially or operationally

For SMEs, this can be a useful way to understand risks, opportunities, customer expectations, and reporting readiness.

What Is Double Materiality?

Double materiality combines two perspectives.

Impact materiality

This looks at the company’s impact on the outside world.

Examples:

  • Does the company generate waste?

  • Does it use significant energy or water?

  • Does it affect worker health and safety?

  • Does it create emissions?

  • Does it rely on suppliers with labor or environmental risks?

  • Does its product affect customers or communities?

Financial materiality

This looks at how sustainability issues affect the company.

Examples:

  • Could energy prices increase costs?

  • Could customer ESG requirements affect sales?

  • Could climate events disrupt operations?

  • Could poor safety practices create legal or operational risk?

  • Could lack of carbon data reduce competitiveness?

  • Could supplier issues delay production?

Together, these two views help SMEs understand what matters.

A Simple Way to Explain It

Double materiality asks two questions:

What impact does our business have?

and

What sustainability issues could affect our business?

Both questions matter.

A company may have a strong impact on the environment, people, or communities. At the same time, sustainability issues may affect its costs, customers, financing, supply chain, or reputation.

Why Double Materiality Matters for SMEs

Many SMEs may not be directly required to conduct a formal double materiality assessment. However, the logic is still useful.

It helps SMEs:

  • Understand sustainability risks

  • Prepare for customer ESG requests

  • Prioritize data collection

  • Avoid generic ESG reporting

  • Connect sustainability to business strategy

  • Identify practical actions

  • Prepare for future reporting expectations

This is especially relevant for SMEs that supply larger companies, export products, or work in sectors where customers request ESG data.

Example: Small Manufacturing Company

A small manufacturer uses electricity, fuel, raw materials, packaging, and labor. It supplies components to larger customers.

Impact view

The company may affect:

  • Climate through electricity and fuel use

  • Environment through waste and packaging

  • Workers through health and safety conditions

  • Customers through product quality

  • Suppliers through purchasing practices

Financial view

The company may be affected by:

  • Rising energy costs

  • Customer ESG questionnaires

  • Carbon data requests

  • Supplier disruption

  • Waste disposal costs

  • Safety incidents

  • Export market requirements

From this, the company may identify energy, emissions, waste, safety, and supplier management as priority topics.

Double Materiality Does Not Need to Be Overcomplicated

For SMEs, the first version does not need to be a complex consulting project.

A practical version can start with a simple matrix:

| Topic | Impact on people/environment | Impact on business | Priority |

|---|---|---|---|

| Energy use | Medium | High | High |

| Waste | Medium | Medium | Medium |

| Worker safety | High | High | High |

| Supplier documentation | Medium | High | High |

| Water use | Low | Low | Low |

The goal is not perfection. The goal is better focus.

How SMEs Can Conduct a Practical Double Materiality Review

Step 1: List possible sustainability topics

Start with topics related to operations, customers, suppliers, employees, and compliance readiness.

Step 2: Assess impact materiality

Ask:

  • Who or what is affected?

  • Is the impact positive or negative?

  • Is it actual or potential?

  • How serious is it?

  • How widespread is it?

  • Can it be prevented or reduced?

Step 3: Assess financial materiality

Ask:

  • Could this topic affect revenue?

  • Could it increase costs?

  • Could it affect customer relationships?

  • Could it affect financing?

  • Could it create operational disruption?

  • Could it affect compliance readiness?

Step 4: Prioritize

Focus on topics that are significant from either or both perspectives.

Step 5: Turn topics into actions

For each priority topic, define data, KPIs, evidence, owner, and next action.

Common SME Double Materiality Topics

Environmental

  • Energy use

  • Greenhouse gas emissions

  • Waste

  • Packaging

  • Water use

  • Materials

  • Pollution

  • Climate risk

Social

  • Worker health and safety

  • Labor practices

  • Training

  • Product quality

  • Customer responsibility

  • Community impact

  • Supplier labor conditions

Governance

  • Business ethics

  • Anti-corruption

  • Supplier management

  • Data privacy

  • Compliance

  • ESG ownership

  • Evidence management

What Good Output Looks Like

A practical double materiality output should include:

  • List of reviewed topics

  • Reason why each priority topic matters

  • Impact perspective

  • Business or financial perspective

  • Stakeholders affected

  • Data needed

  • Evidence needed

  • Suggested KPI

  • Suggested action

  • Responsible owner

This is far more useful than a complex chart with no follow-up.

How AeternumAlly Supports Double Materiality for SMEs

AeternumAlly can help SMEs conduct a structured but practical double materiality workflow.

The system can guide users through:

  • Business context

  • Stakeholder mapping

  • Topic selection

  • Impact assessment

  • Financial relevance assessment

  • Priority scoring

  • AI-assisted explanations

  • KPI suggestions

  • Task generation

  • Evidence requirements

The AI guide should help users think through the assessment, but it should not automatically decide what is material without human review.

Mistakes to Avoid

Mistake 1: Treating double materiality as only a reporting task

It should support decision-making, not just disclosure.

Mistake 2: Scoring everything as high

If every topic is high priority, prioritization has failed.

Mistake 3: Ignoring stakeholders

Customers, employees, suppliers, lenders, and communities may all reveal important sustainability issues.

Mistake 4: Not linking results to action

A materiality assessment is only useful if it leads to data collection, KPIs, and improvement actions.

Final Thought

Double materiality helps SMEs understand sustainability from both sides: how the company affects the world, and how sustainability issues affect the company.

Used properly, it helps SMEs focus on what matters, prepare better ESG data, and turn sustainability into practical business action.
