Selecting GRI Indicators: The 200, 300 & 400 Series

Selecting GRI Indicators: The 200, 300 & 400 Series

A Quick Refresher on GRI Structure

Before we get into selection, you need to understand how GRI is organized. The standards fall into three series, each covering one of the ESG pillars:

On top of these topic-specific standards, there are the GRI Universal Standards (GRI 1, 2, and 3) that apply to every report. GRI 1 sets the foundation, GRI 2 covers general organizational disclosures, and GRI 3 covers the materiality process. These are non-negotiable: every GRI-referenced report includes them.

The topic-specific standards (200, 300, 400 series) are where selection comes in. Each standard has multiple "disclosures" within it: specific data points or qualitative descriptions the company can report on. For example, GRI 305 (Emissions) includes disclosures for Scope 1 emissions (305-1), Scope 2 emissions (305-2), Scope 3 emissions (305-3), GHG emissions intensity (305-4), and reduction of GHG emissions (305-5). You may choose to report on all five, or only the first two if the company does not yet have Scope 3 data.

The Four Inputs That Drive Selection

Indicator selection is not a guessing game. It is driven by four concrete inputs, each of which you should already have by this point in the process:

1. Peer benchmarking results. From Lesson 2.1, you know which indicators your client's peers commonly report on. This is your strongest signal. If every peer reports on GRI 302 (Energy) and GRI 305 (Emissions), those are table stakes: your client should report on them too.

2. The company's past reports. If the company has published sustainability reports before, look at what indicators they have already reported against. Dropping indicators without explanation looks bad: it suggests the company is backtracking. If you want to drop something, have a clear rationale (and document it).

3. Industry relevance. Some indicators are critical for certain industries and irrelevant for others. A mining company must report on GRI 304 (Biodiversity) and GRI 403 (Occupational Health and Safety). A software company probably does not need 304 at all. Industry relevance is partly covered by peer benchmarking, but you should also apply your own judgment here.

4. Materiality assessment results. From Lesson 2.2, you have a prioritized list of material topics. Each material topic maps to one or more GRI standards. If "Climate Change" is a top material topic, GRI 305 is essential. If "Employee Well-being" is high priority, GRI 401, 403, and 404 are in play. The materiality matrix is your justification for including or excluding indicators.

Walking Through the Selection Process

Let us walk through how this actually works in practice. You sit down with your benchmarking notes, the company's past report (if it exists), and the materiality results. Then you go through each GRI series systematically.

GRI 200 - Economic Series

Most companies include GRI 201 (Economic Performance) because it covers revenue, operating costs, employee wages, and community investments (data that typically already exists in the annual report). GRI 205 (Anti-corruption) is included by almost everyone because corruption risk is material across industries. GRI 207 (Tax) is increasingly expected, especially for large companies, because tax governance has become a hot topic with investors and regulators. The rest of the 200 series (202 for Market Presence, 203 for Indirect Economic Impacts, 204 for Procurement Practices, and 206 for Anti-competitive Behavior) are included only when relevant. A company with significant local procurement impact might include 203 and 204. Most skip 206 unless there is a specific reason.

GRI 300 - Environmental Series

This is where selection matters most, because the environmental indicators are the most data-intensive and the most scrutinized. GRI 302 (Energy) and 305 (Emissions) are nearly universal: almost every company reports on them. GRI 303 (Water and Effluents) and 306 (Waste) are standard for manufacturing, FMCG, and heavy industry. GRI 304 (Biodiversity) is relevant for extractives, agriculture, and real estate companies with operations near sensitive areas, and is increasingly expected as biodiversity disclosure regulations emerge. GRI 301 (Materials) is relevant for companies with significant raw material consumption. The key question for each: does the company have data for this, and is it material?

GRI 400 - Social Series

The social series is broad. GRI 401 (Employment), 403 (Occupational Health and Safety), 404 (Training and Education), and 405 (Diversity and Equal Opportunity) are included in nearly every report. GRI 413 (Local Communities) is common for companies with significant community impact. GRI 414 (Supplier Social Assessment) and 408/409 (Child Labor / Forced Labor) are increasingly expected as supply chain due diligence becomes a regulatory requirement in many jurisdictions. GRI 418 (Customer Privacy) is critical for technology and financial services companies. The rest are situational.

Building the Data Requirement Sheet from Your Selection

Once you have finalized the indicator list, it becomes the backbone of your data requirement sheet (the Excel template you share with the client). Each selected GRI standard translates into a set of specific data points the client needs to provide.

For example, if you have selected GRI 305 (Emissions), the data requirement sheet will include rows for:

• Scope 1 GHG emissions (in tonnes CO2e), broken down by source if possible
• Scope 2 GHG emissions (location-based and market-based, in tonnes CO2e)
• Scope 3 GHG emissions by category (if the company tracks them)
• GHG emissions intensity ratio and the denominator used
• Reduction in GHG emissions achieved during the reporting period

You request this data for the current reporting year plus two to three previous years, so the report can show trends. The data requirement sheet is your primary communication tool with the client during the data collection phase: everything the client needs to provide is in one place, organized by GRI standard.

Common Pitfalls in Indicator Selection

A few mistakes that come up repeatedly:

• Selecting too many indicators. Ambition is good, but if the company cannot provide data for half the indicators you selected, you end up with empty sections or vague narrative filler. Be realistic about data availability.
• Selecting too few indicators. Going too minimal makes the report look thin and raises questions from rating agencies about what the company is hiding. Find the balance.
• Dropping indicators without explanation. If the company reported on GRI 303 (Water) last year and you drop it this year, readers will notice. Always explain changes in scope: a brief note in the "About the Report" section is sufficient.
• Ignoring disclosure levels within a standard. You might include GRI 305 but only report on disclosures 305-1 and 305-2, skipping Scope 3 (305-3). That is fine, but be transparent about it in the GRI Content Index. Partial reporting is better than no reporting, as long as you are honest about the gaps.
• Not aligning with BRSR requirements. For Indian companies, the BRSR framework has its own set of mandatory disclosures. Many of these overlap with GRI, but not all. If the company files BRSR, make sure your GRI indicator selection covers the overlapping areas so data is consistent across both reports.

Getting Client Sign-off

Before you build the data requirement sheet and start collecting data, get the client to formally agree on the indicator list. This is not a formality: it is a safeguard.

Present the selection as a structured document: each indicator, why it is included (or excluded), and what data will be needed. Walk the client through it. Give them a chance to push back. If they want to add or remove something, discuss the implications.

The reason this matters: if you start collecting data against an indicator list the client has not approved, you risk doing work that gets thrown out later. Worse, the client may complain that you asked their departments for data they "never agreed to report on." Getting sign-off on the indicator list is a two-minute conversation that prevents weeks of rework.
