Our reporting

Sustainable development is critical to the continued success and growth of our business. Reporting on our progress is an integral part of our corporate disclosure and reporting practice.

We believe that to be a truly sustainable company we must report our impact in a meaningful way. Our reporting is:

  • Authentic: We report on the the issues that matter to us and the communities in which we work.
  • Measurable: We report consistently and openly on our impacts and progress against our 2020 targets.
  • Credible: We report using clear, publicly available methodologies and best practice.

How we report

We present our most material sustainability disclosures in our Annual Report using the International Integrated Reporting Council (IIRC) Framework as a guide. Our aim is to increase our alignment with the IIRC Framework as we progress.

We also subscribe to the principles inherent in both the Global Reporting Initiative (GRI) and United Nations Global Compact (UNGC).

Our Sustainability and Responsibility Performance Addendum contains additional information which is not included in the Annual Report. It is structured as two indices: the GRI index follows the new G4 framework, while the UNGC index follows the UNGC advanced reporting criteria and serves as our annual communication on progress.

Visit our Reporting Centre to access our current and historical Annual Reports and performance addendums.

Our aim is to ensure that between our Annual Report, the performance addendum and our website we provide the information our diverse stakeholders expect and need.

We welcome your views on our reporting and on our approach to sustainability in general. We encourage you to give us your feedback by emailing


We align our reporting with what we believe to be the best standards for non-financial reporting. We believe in reporting against reliable data and strive to improve the quality of our non-financial disclosures.

Towards these aims, we engage independent auditors to provide limited assurance of environmental performance data (carbon emissions, water usage, biochemical oxygen demand (BOD), and waste to landfill) as well as health and safety data. Download PwC’s most recent assurance statement.
