Thousands of companies now publish reports. Yet very few of them influence real decisions.

Most reports describe activities.
Very few shape strategy.

And that is the problem.

Because a sustainability report is not an end in itself.
It is a tool for identifying what truly matters. Your most significant impacts, risks, and opportunities—and for guiding decisions that create value for:

• The business
• Stakeholders
• The planet

If your report does not do this, it is not just ineffective—it is a missed opportunity.

Where Companies Go Wrong

In our work with organisations across sectors and geographies, we consistently see the same challenges:

• Reporting treated as a compliance or communications exercise
• Materiality assessments done superficially or too late
• Lack of connection between value chain → impacts → decisions
• Over-reporting on immaterial topics, under-reporting on critical ones
• Reports that cannot withstand external assurance scrutiny

The result?

Reports that look polished—but do not drive value, strategy, or competitive advantage.

What First-Class Reporting Looks Like

A first-class sustainability report is built on one foundation:

Value chain–based double materiality

This means:

• Understanding your full value chain
• Identifying where you create—or erode—value
• Assessing:
  • Impacts (on society and environment)
  • Risks and opportunities (for the business)

And translating this into:

• Clear priorities
• Defensible decisions
• Strategic actions

In this context, reporting becomes:

A decision-making system, not a disclosure exercise.

From Theory to Action — The Missing Link

Many professionals understand the GRI Standards.

Far fewer know how to apply them in practice.

The gap is not knowledge.
It is execution.

What is needed is a clear plan of action:

• What decisions need to be made?
• What actions need to be taken?
• What evidence needs to be collected?
• What exactly needs to be reported?

Without this structure, even experienced teams struggle.

The Hidden Weakness — Poor Decision-Making Structures

One of the most critical—and least discussed—reasons sustainability reporting fails is not technical.

It is structural.

Most organisations do not have decision-making systems designed to handle sustainability.

1. Sustainability Is Not Embedded in Decision Rights

In many organisations:

• Sustainability is assigned to a team, not embedded across functions
• Operational teams are not accountable for sustainability-related impacts
• Data is collected—but ownership of decisions is unclear

As a result:

Sustainability becomes everyone’s responsibility—and no one’s decision.

2. Senior Decision-Makers Are Not Mandated to Act

At board and executive level, a more serious issue emerges:

• Sustainability is often presented, but not decided upon
• There is no requirement to:
  • Evaluate impacts, risks, and opportunities
  • Prioritise them
  • Take documented decisions

In many cases, sustainability appears on the agenda—but:

There is no mandate to act, no structured decision process, and no accountability for outcomes.

This creates a critical gap between information and action.

3. Data Collection Without Decision Use

Organisations invest heavily in:

• Data collection
• KPIs
• Reporting systems

But without a decision-making framework:

• Data remains descriptive
• Insights are not translated into action
• Reporting becomes an output exercise, not a management tool

4. The Consequence: Weak, Non-Defensible Decisions

When decision structures are weak:

• Materiality assessments lack rigour
• Priorities are unclear or inconsistent
• Trade-offs are not explicitly evaluated
• Decisions cannot be defended under scrutiny (investors, regulators, assurance providers)

In today’s environment, this is a serious risk.

Because sustainability is no longer voluntary positioning—it is increasingly tied to:

• Regulation
• Capital allocation
• Reputation
• Legal exposure

5. What Strong Decision-Making Looks Like

To deliver real value, organisations need to move from informal discussion to structured decision-making.

This means:

• Embedding sustainability into decision rights across the value chain
• Requiring senior decision-makers to:
  • Review material impacts, risks, and opportunities
  • Make explicit, documented decisions
• Linking data collection directly to:
  • Decisions
  • Actions
  • Accountability

At its core:

Sustainability reporting must be designed to support decisions—not just disclosures.

This is why value chain–based double materiality is so powerful.

It does not just identify what matters.

It creates the foundation for clear, structured, and defensible decision-making across the organisation.

A Practical Pathway to First-Class Reporting

To address this gap, we have developed a structured pathway:

GRI Reporting Programme: From Understanding to Implementation

This is not a theoretical course.

It is a working system that enables participants to begin reporting from day one.

What makes it different:

• Built around a step-by-step Plan of Action
• Fully aligned with the GRI Standards
• Focused on value chain–based double materiality
• Designed to support:
  • Real decisions
  • Real outputs
  • Assurance-ready reporting

Every component is practical:

• Group exercises
• Templates
• Handouts

All mapped directly to the plan of action—so participants always know:

what to do, when to do it, and how to do it.

What You Will Be Able to Do

By following the full pathway, participants are able to:

• Identify and prioritise material impacts, risks, and opportunities
• Conduct a robust double materiality assessment
• Structure a report that is:
  • Strategically relevant
  • Decision-useful
  • Assurance-ready
• Avoid over-reporting and focus on what truly matters
• Deliver value to:
  • The business
  • Stakeholders
  • The planet

In a world of increasing complexity, scrutiny, and competition:

Sustainability reporting is becoming a defensibility tool.

AI can generate content.
But it cannot defend decisions.

That requires:

• Clear logic
• Robust methodology
• Evidence-based prioritisation

That is what first-class reporting delivers.

to reporting as a decision-making system:

This case study is based on the 2013-2014 Sustainability Report by ETH Zurich published on the Global Reporting Initiative Sustainability Disclosure Database that can be found at this link. Through all case studies we aim to demonstrate that CSR/ sustainability reporting done responsibly is achieved by identifying an organization’s or company’s most important impacts on the environment and stakeholders and by measuring, managing and changing. 

Committed to providing students and staff with skills and opportunities to approach and effectively address complex sustainable development issues, ETH Zurich has made sustainability a central priority.  Tweet This! In order to cultivate sustainability-related competencies in students and staff ETH Zurich took action to:

• integrate sustainability across departments and degree programs
• encourage students and staff to learn about sustainability through innovative activities and events
• offer summer and winter schools on sustainability
• bring faculty and students working on sustainability-related theses into contact with private and public sector partners
