What it is

ESG Materiality Matrix Guide, without the jargon

A materiality matrix plots ESG topics by their importance to stakeholders against their significance to the business, so a company can focus reporting and effort on what is material rather than disclosing everything. This guide walks through building one, including the double-materiality lens now expected by frameworks like the ISSB and GRI.

Why it matters

Why sustainability act on this

  • Frameworks require companies to report on their material topics
  • It focuses limited resources on issues that actually matter
  • Double materiality is increasingly expected by investors and regulators

How we deliver

A clear, auditable process

  1. 01
    Identify topics

    Draw a candidate list from peers, frameworks and the value chain.

  2. 02
    Engage & score

    Weigh each topic by stakeholder concern and business impact.

  3. 03
    Plot & prioritise

    Map topics onto the matrix and set reporting priorities.

Two axes, one decision

What matters — to whom

A materiality matrix plots every ESG topic on two axes at once, and a topic earns disclosure if it ranks high on either — the essence of double materiality.

Impact materiality
  • Effect on people & environment
  • Weighed by stakeholder concern
  • The outward-facing lens
Financial materiality
  • Effect on enterprise value
  • Risk & opportunity to the business
  • The investor-facing lens

Plot each topic on both axes — material if it ranks high on either. That is double materiality.
