About this report

Selecting our report content

The materiality process we adopted takes into consideration guidance in respect of materiality provided by the International Integrated Reporting Council, the GRI's G4 guidelines and the AccountAbility AA1000 Stakeholder Engagement Standard.

The materiality process involved gathering data from stakeholder engagements which have taken place across the organisation to identify the issues of greatest concern. We also undertook surveys within the company and with external stakeholders to gain insight into their views of our reporting which we used to refine the way in which we present the report. Other information reviewed during our process to define our material issues for reporting included:

  • Reports to the Social, Ethics and Sustainability Committee of the Board;
  • The strategic and operational risks identified by the business;
  • Topics covered in previous sustainability reporting and in peer group reporting; and
  • Topics covered in sector and market reports and in the media.
Inputs used to determine topics considered for reporting


Supported by this data, discipline leaders in the business participated in a one-day workshop to debate the issues and arrive at a consolidated list of topics for reporting, by:

  1. Identifying topics which are material for reporting and relevant in our context, based on an assessment of business and stakeholder concerns;
  2. Grouping of topics into issues to inform the structure of the report;
  3. Prioritisation of issues, based on the significance of the organisation’s economic, environmental and social impacts and the significance of stakeholder concerns.
Prioritisation of themes identified for reporting

The outcomes of this process were used to select content for our report. These material issues are then linked to the GRI Aspects to be reported, a full list of which can be viewed below, and to inform the selection of GRI indicators for disclosure. A full list of GRI indicators and aspects reported is included in the GRI contents index.

The material issues identified and the final report were reviewed by the Executive Committee and the Social, Ethics and Sustainability Committee of the Board to determine whether:

  • The material issues for reporting represented a balanced and comprehensive view of the critical areas of concern for the business and for stakeholders; and
  • There were additional or emerging issues not identified, but which should be included.
