Reporting principles

We support the reporting principles set out in the GRI G4 guidelines. For defining report content, these are: stakeholder inclusiveness; sustainability context; materiality; and completeness. For defining report quality, these are: balance; comparability; accuracy; timeliness; clarity; and reliability.

This table sets out how our 2015 annual review responds to each element of the GRI G4 reporting principles.

Category – content

Principle What it means Our response
Stakeholder inclusiveness The report should identify its stakeholders and explain how the reporting organisation has responded to their reasonable expectations and interests. See ‘Transparent good governance’ for details on our stakeholders.
Sustainability context The report should present the organisation’s performance in the wider context of sustainability. See ‘The big picture’ for ArcelorMittal’s sustainability context, and ‘Long-term sustainability outlook’.
Materiality The report should cover aspects that:
  • reflect the organisation’s significant economic, environmental, and social impacts; or
  • would substantively influence the assessments and decisions of stakeholders.
See ‘Long term sustainability outlook’ and ‘Sustainability’. To see how we arrived here, refer to ‘Our materiality story’.
Completeness The report should include coverage of material aspects and their boundaries, sufficient to reflect significant economic, environmental and social impacts, and to enable stakeholders to assess the organisation’s performance in the reporting period. Our coverage of material topics is explained in the scope, boundaries and methodologies section.

Category – quality

Principle What it means Our response
Balance The report should reflect positive and negative aspects of the organisation’s performance to enable a reasoned assessment of overall performance. Throughout our report we identify both the challenges and the opportunities that we face, including open discussion of the disruptions to our business that have occurred during the year. We also report fully on the same key performance indicators as last year, regardless of whether performance has improved or declined.
Comparability The organisation should select, compile and report information consistently. The reported information should be presented in a manner that enables stakeholders to analyse changes in the organisation’s performance over time, and that could support analysis relative to other organisations. We have brought together financial and non-financial reporting for the first time in this annual review. Nonetheless, we continue to report the same financial and non-financial data as reported in our 2014 annual review and SD report, and we include the 2014 comparative figures.
Accuracy The reported information should be sufficiently accurate and detailed for stakeholders to assess the organisation’s performance. We explain our methodology for calculating performance in our basis of reporting document. Deloitte Audit has provided limited assurance for certain environmental data, as set out in their assurance statement.
Timeliness The organisation should report on a regular schedule so that information is available in time for stakeholders to make informed decisions. We report financial and non-financial data annually through this annual review and our Form 20-F.
Clarity The organisation should make information available in a manner that is understandable and accessible to stakeholders using the report. We have created this annual review as a microsite with options to download and print information as required.
Reliability The organisation should gather, record, compile, analyse and disclose information and processes used in the preparation of a report in a way that they can be subject to examination and that establishes the quality and materiality of the information. We explain our methodology for calculating performance in our basis of reporting document. Deloitte Audit has provided limited assurance for certain environmental data, as set out in their assurance statement.
