Identify the ESG Issues That Matter Most

Organisations face an increasingly broad range of environmental, social and governance (ESG) issues. However, not every ESG topic carries the same level of importance for every business.

A materiality assessment helps organisations identify and prioritise the sustainability issues that are most significant to their business, stakeholders and long-term success. Rather than attempting to address every ESG topic equally, companies can focus their resources on the issues that present the greatest risks, opportunities and strategic value.

Whether preparing an ESG report, developing a sustainability strategy or responding to evolving investor expectations, a robust materiality assessment provides a clear foundation for informed decision-making.

Why Conduct a Materiality Assessment?

A well-designed materiality assessment enables organisations to make more informed strategic decisions by identifying the ESG topics that require the greatest management attention.

Key benefits include:

  • Prioritising ESG issues based on business relevance and stakeholder expectations
  • Supporting enterprise risk management and long-term resilience
  • Strengthening sustainability strategy and business planning
  • Improving the quality and credibility of ESG reporting
  • Enhancing communication with investors, customers and other stakeholders
  • Demonstrating that sustainability decisions are supported by a structured assessment process

Materiality assessments should be reviewed periodically, as stakeholder expectations, business operations and regulatory requirements continue to evolve.

What is Double Materiality?

As sustainability reporting continues to develop globally, organisations are increasingly moving beyond traditional single materiality towards a broader double materiality approach.

Financial Materiality (Outside-In)

Financial materiality considers how sustainability-related risks and opportunities may affect an organisation’s financial performance, enterprise value and long-term business success.

Examples include climate change, supply chain disruptions, changing regulations and resource availability.

Impact Materiality (Inside-Out)

Impact materiality examines how an organisation’s activities affect the environment, society and the wider economy, regardless of whether those impacts currently have financial consequences.

Examples include greenhouse gas emissions, biodiversity impacts, employee wellbeing and human rights throughout the value chain.

By considering both perspectives together, organisations gain a more comprehensive understanding of their sustainability priorities and can make better-informed strategic decisions.

Our Double Materiality Approach

GreenCo applies a structured methodology that evaluates both financial materiality and impact materiality to provide a balanced view of ESG priorities.

Our assessment considers:

  • Business strategy and industry-specific ESG risks
  • Stakeholder expectations and concerns
  • International sustainability reporting frameworks
  • Current and emerging regulatory developments
  • Short-, medium- and long-term sustainability impacts

The results are consolidated into a clear materiality matrix, supported by management analysis and practical recommendations that can be incorporated into ESG reports and sustainability strategies.

Our Five-Step Methodology

Step 1 — ESG Topic Identification

We identify potentially material ESG topics based on your industry, international reporting standards, peer benchmarking and organisational context.

Step 2 — Stakeholder Engagement

Relevant internal and external stakeholders participate in customised surveys and interviews to provide both quantitative ratings and qualitative insights.

Step 3 — Materiality Evaluation

Stakeholder feedback, management perspectives and business considerations are analysed to evaluate the significance of each ESG topic under both financial and impact materiality perspectives.

Step 4 — Materiality Matrix Development

The assessment results are visualised through a materiality matrix, highlighting the ESG topics that should receive the highest strategic priority.

Step 5 — Board Review and Strategic Integration

We present the assessment results to management and the Board, supporting validation and integration into ESG reporting, sustainability strategies and future action plans.

Supporting International Sustainability Reporting

Our materiality assessment methodology aligns with leading international sustainability reporting frameworks, including:

  • IFRS Sustainability Disclosure Standards (ISSB)
  • HKEX ESG Reporting Code
  • GRI Standards
  • SASB Standards
  • European Sustainability Reporting Standards (ESRS) for organisations applying double materiality principles

Our consultants can also assist organisations in updating their materiality assessment periodically to reflect changing stakeholder expectations and evolving business environments.
