When companies think about ESG reporting, one of the most crucial concepts they need to understand is materiality. In simple terms, materiality helps businesses decide what issues matter most to their stakeholders, investors, and the planet. But here’s the catch, not all materiality is the same.

Today, ESG professionals and corporate sustainability teams must choose between financial materiality, impact materiality, and double materiality to determine what gets reported. Each approach tells a different story. In this article, we’ll break down what these terms mean, how they work, and why they matter.

What Does ESG Materiality Mean?

Materiality in ESG (Environmental, Social, and Governance) reporting refers to identifying which issues are important enough to influence decision-making. These can be financial, environmental, social, or reputational risks that affect a company or that the company causes.

There are three main approaches:

Financial Materiality – Looks at how ESG factors affect the company’s financial performance.
Impact Materiality – Looks at how the company’s actions affect society and the environment.
Double Materiality – Combines both to give a full picture of ESG risks and opportunities.

Financial Materiality: How ESG Risks Affect the Company

What is financial materiality?

Financial materiality focuses on how external ESG risks influence a company’s bottom line. For instance, if climate change disrupts your global supply chain, that risk becomes financially material because it threatens revenue, cost structures, or operations.

Key highlights:

Focus: ESG issues that impact the company’s financial performance, value, and position
Example: Extreme weather events raising insurance costs or delaying product shipments
Audience: Investors, shareholders, lenders, analysts
Reporting Format: Typically disclosed in annual financial reports
Relevant for: Regulatory filings, investor communications, and TCFD-aligned reporting

Why it matters:
Investors and financial analysts need visibility into ESG risks that may impact profitability, valuation, or capital access. Financial materiality ensures ESG issues are treated like any other business risk.

Impact Materiality: How the Company Affects the World

What is impact materiality?

Impact materiality flips the perspective. It examines how a company’s operations affect the environment, society, and the broader economy. This includes emissions, human rights, water usage, waste, and ethical labor practices.

Key highlights:

Focus: ESG impacts caused by the company
Example: A manufacturing plant releasing emissions that contribute to air pollution or climate change
Audience: Consumers, employees, communities, civil society, and some investors
Reporting Format: Disclosed in sustainability reports or non-financial disclosures
Relevant for: GRI (Global Reporting Initiative), CSRD (EU Corporate Sustainability Reporting Directive)

Why it matters:
Stakeholders, especially customers and employees want transparency about a company’s footprint. Impact materiality supports ethical accountability and long-term brand trust.

Double Materiality: The ESG Gold Standard

What is double materiality?

Double materiality merges the previous two approaches. It looks both at how ESG risks affect the company (financial materiality) and how the company affects the world (impact materiality).

This dual approach is required under the EU’s CSRD and is increasingly adopted in integrated ESG frameworks.

Key highlights:

Combines effects on the company and effects by the company
Offers a comprehensive view of risks and responsibilities
Helps companies future-proof their strategy, respond to investor demands, and address public expectations

Why it matters:
Double materiality is becoming the global standard. It ensures companies are not just protecting shareholders but also addressing the needs of people, the planet, and future generations.

Which ESG Materiality Approach Should You Use?

The answer depends on your audience, industry, and regulatory environment.

Public companies with global investors often prioritize financial materiality aligned with ISSB or SASB.
Sustainability-focused firms or EU-based entities are expected to report impact materiality under GRI and CSRD.
Progressive companies with strong ESG integration aim for double materiality, offering a more holistic picture of risk, opportunity, and responsibility.

How to Conduct a Materiality Assessment?

Map stakeholders: Investors, regulators, employees, suppliers, NGOs, etc.
Identify ESG topics: Climate risk, supply chain ethics, diversity, data privacy, etc.
Score impact and relevance: Rate each issue by how much it affects your company and how much your company affects it.
Visualize findings: Use a materiality matrix to plot priority issues
Align with frameworks: GRI, ISSB, SASB, CSRD, or TCFD

Materiality is no longer just a checkbox. It is the foundation for effective ESG reporting, strategy, and accountability.

Financial materiality helps you assess what threatens your value.
Impact materiality ensures you take responsibility for what your business affects.
Double materiality gives you the full picture that regulators, stakeholders, and future generations expect.
