Materiality Assessment in Practice

Materiality Assessment in Practice

Does the Company Already Have One?

This is the first question you ask. The answer determines your entire approach to this topic.

Scenario A: They have done a materiality assessment before. Most companies that have published even one sustainability report will have conducted a materiality assessment at some point. The common practice is to reuse it for two to three years before refreshing it. If the assessment is recent (within the last two years), you refer to it. You write the materiality chapter based on it. You use the material topics it identified to guide the rest of the report. This is straightforward.

Scenario B: They have never done one. This is where things get interesting. The company either needs to conduct one before the report, or you need to help them through the process. In recent years, this has become more complex because of the rise of "double materiality" (more on that below).

Scenario C: The grey zone. They did one three or four years ago and have not updated it. The material topics may still be relevant, but the world has changed: new regulations, new stakeholder expectations, new risks. You will need to have a frank conversation about whether to refresh it or work with what exists.

Double Materiality: The New Buzzword

If you are working in ESG reporting in 2026, you will hear "double materiality" in almost every engagement. Here is what it actually means and why it has taken over the conversation.

Traditional materiality (sometimes called "single materiality" or "impact materiality") asks one question: How does the company impact the environment and society? This is the GRI approach: identify the topics where the company has the most significant impact on people and planet, and report on those.

Financial materiality flips the question: How do environmental and social changes impact the company financially? This is the investor lens: what sustainability risks and opportunities affect the company's bottom line, cash flow, or enterprise value? This is the ISSB/IFRS approach.

Double materiality combines both. A topic is "material" if it is significant from either direction, or both. The European CSRD regulation formally requires double materiality, but here is the practical reality: companies everywhere are adopting it, even when CSRD does not apply to them. It has become the standard expectation because it sounds more comprehensive, and nobody wants to look behind the curve.

How It Actually Happens on the Ground

The textbook version of a materiality assessment involves structured surveys, statistical analysis, weighted scoring, and a beautiful materiality matrix. The reality is messier.

Here is the typical process when you are helping a company conduct one:

Step 1: Identify stakeholder groups. You work with the client to list out who their stakeholders are, both internal (employees, board, management) and external (investors, customers, communities, regulators, suppliers). This is usually a half-day workshop or a series of calls.

Step 2: Develop a long list of topics. Pull from GRI topic standards, SASB's industry-specific materiality map, peer reports, and the company's own risk assessments. You will typically start with 20-30 potential topics and need to narrow down.

Step 3: Engage stakeholders. This is where the process varies wildly. Some companies send out proper surveys to hundreds of stakeholders. Others do a handful of interviews with senior management and call it done. The quality of this step directly affects the credibility of the results.

Step 4: Score and prioritize. Each topic gets rated on its significance: for impact materiality (how significant is the company's impact?) and for financial materiality (how significant is the financial risk or opportunity?). The scoring methodology should be documented.

Step 5: Build the matrix and validate. Plot the topics on a materiality matrix (typically a 2x2 or scatter plot). Present it to senior management for validation. This is important: the board or leadership team needs to sign off on the final list of material topics because these topics drive the entire report.

Does Materiality Actually Influence the Report?

The honest answer: yes, but with some nuance.

In a well-run engagement, the material topics directly determine which sections of the report get the most space, which GRI indicators you report against, and where you invest effort in data collection. If "climate change and emissions" is the top material topic, your Environmental section should be the most detailed chapter in the report.

In practice, though, many companies follow a predictable pattern regardless of materiality results. They report on the same topics their peers report on, in the same structure, with the same level of detail. The materiality assessment confirms what everyone already knew rather than revealing something new.

This does not mean materiality is useless. Even when the results are unsurprising, the process has value. It creates documented evidence that the company engaged stakeholders and made deliberate choices about what to report. For assurance, for ratings agencies, and for credibility with investors, this documentation matters.

The Indian Context

If you are working with Indian companies, there is a reality you should know: materiality is often not taken very rigorously. Many Indian companies treat the materiality assessment as a compliance checkbox rather than a genuine strategic exercise. The surveys go out, responses come back, a matrix gets plotted, and then reporting continues largely as before.

This is changing, albeit slowly. As more Indian companies face scrutiny from global investors and as SEBI's BRSR requirements mature, the quality of materiality assessments is improving. But if you walk into an engagement expecting a European-style double materiality exercise with months of stakeholder engagement, you may be disappointed. Calibrate your approach to what the client is ready for, and push them toward better practices incrementally.

Writing the Materiality Chapter

Regardless of how the assessment was conducted, the materiality chapter in the report typically covers:

• Approach and methodology. How was the assessment conducted? What framework did you follow? When was it last updated?
• Stakeholder groups engaged. Who was consulted? How many responses? What engagement methods were used?
• The materiality matrix. The visual representation of results. Include clear axis labels and a legend.
• List of material topics. Usually 8-15 topics, ranked or grouped by priority tier.
• How material topics map to the report. A brief note on where each material topic is addressed in the report. This can be a simple table: "Material Topic | Report Section | Page Number."

One thing to avoid: do not oversell the rigor of the process if it was not rigorous. If the company conducted a lightweight internal assessment with limited external stakeholder input, do not describe it as a "comprehensive multi-stakeholder engagement." Readers (especially assurance providers and ratings analysts) can tell the difference. Be accurate about what was done.
