Why Traditional Double Materiality Matrices Are Failing Decision-Makers — And What to Do Instead

For years, the traditional two-axis double materiality matrix has been presented as one of the defining outputs of sustainability reporting. Colourful charts plotting “impact materiality” against “financial materiality” have become common across sustainability reports globally.

The problem is that many of these matrices provide very little real decision-making value.

Whilst they may create the appearance of structure and prioritisation, they often fail to show:

• where impacts, risks, and opportunities occur
• which parts of the value chain are exposed
• where dependencies and vulnerabilities exist
• which business functions must act
• how decisions are being made
• how resilience is being strengthened
• where management attention and capital allocation should focus

In many cases, the matrix becomes a highly subjective exercise that lacks transparency.

Users of the report, including investors, regulators, procurement teams, lenders, customers, and other stakeholders, are frequently unable to understand:

• why a topic was positioned in a specific location
• what assumptions were used
• how severity or financial exposure were assessed
• which methodologies were applied
• which evidence supported the conclusions
• where exactly the organisation faces its greatest sustainability-related exposures

As a result, the process can unintentionally create:

• weak governance visibility
• fragmented management responses
• poor operational integration
• limited strategic usefulness
• accusations of selective prioritisation or “materiality theatre”

The reality is that many organisations stop at identifying what is material — but fail to translate materiality into structured decision-making.

This is where the value chain decision-making matrix becomes significantly more powerful.

Moving Beyond Prioritisation Toward Decision Intelligence

A value chain decision-making matrix transforms materiality from a reporting exercise into a management system.

Rather than simply ranking sustainability topics on a chart, the framework maps impacts, risks, opportunities, dependencies, resilience exposures, and value creation dynamics across the value chain.

This allows organisations to clearly identify:

• where risks originate
• where impacts occur
• where business dependencies exist
• where interventions are required
• where operational vulnerabilities may emerge
• where long-term value may be created or diminished

Most importantly, it demonstrates that management understands how sustainability issues influence operational continuity, resilience, competitiveness, and long-term business success.

For investors and other stakeholders, this is significantly more valuable than a traditional matrix because it demonstrates organisational maturity, governance capability, and preparedness.

 Why the Value Chain Perspective Matters

Many of the largest sustainability-related impacts, risks, and opportunities occur outside direct operations.

This includes:

• supply chain vulnerabilities
• logistics dependencies
• transition risks
• human rights exposures
• energy dependencies
• circular economy challenges
• customer use-phase impacts
• regulatory exposures
• climate-related disruptions

A traditional matrix often fails to clearly visualise these relationships.

By contrast, a value chain decision-making framework can map sustainability issues across:

• procurement and supplier integration
• raw material extraction
• manufacturing
• logistics
• marketing and sales
• customer use
• end-of-life and circularity

This creates significantly greater visibility and allows organisations to make more targeted and informed decisions.

Materiality Should Be Transparent

One of the largest weaknesses in modern sustainability reporting is that materiality methodologies are often poorly explained.

If materiality determines:

• what enters the report
• what receives management attention
• what receives investment
• what receives mitigation measures
• what receives governance oversight

then stakeholders should be able to understand how those decisions were made.

A robust materiality process should therefore include:

• recognised methodologies
• assumptions
• thresholds
• severity calculations
• likelihood calculations
• stakeholder engagement methods
• scoring methodologies
• references and evidence
• value chain assessment logic
• links to recognised frameworks and standards

This may include:

• GRI Standards
• ESRS
• OECD Guidelines for Multinational Enterprises
• UN Guiding Principles on Business and Human Rights (UNGPs)
• climate-related methodologies
• sector guidance
• scientific and regulatory references

A detailed methodology section demonstrates that the organisation takes materiality seriously and approaches sustainability reporting systematically, rigorously, and transparently.

This significantly strengthens:

• credibility
• defensibility
• assurance readiness
• investor confidence
• governance confidence
• decision-usefulness 

Operationalising the Integrated Reporting Value Creation Model

The Integrated Reporting Value Creation Model provides an important conceptual framework for understanding how organisations use and affect different forms of capital — financial, manufactured, intellectual, human, social and relationship, and natural capital — to create, preserve, or erode value over time. Its major strength lies in promoting integrated thinking and demonstrating the connectivity between strategy, governance, performance, risks, opportunities, and long-term value creation.

More advanced value creation models increasingly strengthen this approach by incorporating measurable inputs, outputs, impacts, stakeholder considerations, and sustainability outcomes, thereby improving transparency, accountability, and the communication of how organisations create or diminish value for the business, stakeholders, society, and the environment.

However, even sophisticated value creation models often remain primarily descriptive rather than decisional. Whilst they may explain what value is being created and provide useful visibility over outputs and impacts, they are not designed to provide detailed operational intelligence across the value chain. On their own, they do not sufficiently demonstrate where impacts, risks, opportunities, dependencies, and resilience vulnerabilities occur, nor do they clearly identify which business functions, suppliers, operational processes, stakeholder relationships, or parts of the value chain require targeted management attention, prioritised interventions, or resource allocation decisions.

This is where a Value Chain Decision Framework becomes highly complementary and strategically important. The framework operationalises the principles of Integrated Reporting by transforming broad value creation concepts into a structured governance, resilience, and decision-making system that maps impacts, risks, opportunities, dependencies, resilience exposures, and value creation dynamics across procurement, operations, logistics, customer use, and end-of-life activities. In doing so, it extends the connectivity principle of Integrated Reporting by making operational relationships, leverage points, and dependencies visible across the value chain.

Why Investors Need Operational Visibility

Without such operational visibility, value creation models risk remaining primarily strategic communication tools rather than practical management and decision-support instruments. By integrating a Value Chain Decision Framework, organisations can demonstrate not only that they understand value creation conceptually, but also that they understand precisely where value is being created, preserved, diminished, or exposed to risk — and, critically, where management attention, targeted interventions, and resource allocation are required to strengthen resilience, reduce harm, support better decisions, improve stakeholder outcomes, and enhance long-term competitiveness and sustainable value creation.

Ultimately, the objective should not simply be the creation of value for the business alone, but the creation, preservation, and protection of value for the business, stakeholders, society, and the planet. A Value Chain Decision Framework helps organisations better understand where decisions may strengthen resilience, reduce harm, improve stakeholder outcomes, allocate resources more effectively, and support long-term sustainable development across interconnected economic, environmental, and social systems.

Sustainability Reporting Should Support Better Decisions

The purpose of sustainability reporting should not simply be disclosure.

It should support:

• better decisions
• stronger governance
• improved resilience
• operational visibility
• risk management
• stakeholder confidence
• long-term value creation

This requires organisations to move beyond static materiality visuals and toward systems that support integrated decision-making across the value chain.

The organisations that will lead in the coming years will not necessarily be those producing the most disclosures.

They will be the organisations that best understand:

• where their impacts occur
• where their dependencies exist
• where risks emerge
• where resilience must be strengthened
• where value can be created for the business, stakeholders, and the planet
