Our Reporting

Sustainability and responsibility are critical to the success of our business, and reporting on them is an integral part of our corporate disclosure and reporting practice.

Between 2003 and 2013, Diageo published an annual global Sustainability & Responsibility Report each year alongside our Annual Report. In 2014, to start our journey towards integrated reporting, for the first time we presented our most material sustainability and responsibility disclosures in our Annual Report using the IIRC (International Integrated Reporting Council) Framework as a guide. Our aim is to increase our alignment with the IIRC Framework as we go forward. The Annual Report can be downloaded at

We recognise, however, that many of our stakeholders rely on other information we used to disclose in the separate Sustainability & Responsibility Report, and which is not included in our integrated Annual Report. We also continue to subscribe to the principles inherent in both the Global Reporting Initiative (GRI) and United Nations Global Compact (UNGC).

For these reasons we also publish a Sustainability & Responsibility Performance Addendum, 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.

Our aim is to ensure that between our Annual Report., the Performance Addendum and the content throughout this website, we provide the information our diverse stakeholders expect and need.

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


We aim to 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.

We also engage the London Benchmarking Group to assure our community investment data and methodology. Download LBG’s most recent statement.
