ESG reporting approach

Our ambition is to be one of the best performing, most trusted and respected consumer products companies in the world.

Worker With Johnie Walker Bottles

To achieve that ambition, we need to make sure we are doing business the right way, from grain to glass. Thinking about the long-term value and impact we create, and the risks and opportunities of our operating environment and business model,ensuring we are proud of what we do at work, at home and in our communities.

Reporting transparently on environmental, social and governance (ESG) issues plays a vital role in delivering our strategy. It helps us to manage ESG risks, seize opportunities and promote sustainable development everywhere we live, work, source and sell.

How we report

Within our Annual Report we present our most material disclosures and describe how our strategy delivers value for our business and our communities, using the International Integrated Reporting Council (IIRC) Framework as a guide.

Our ESG Reporting Index is where we give additional disclosures in line with the GRI Standards index and the UNGC advanced reporting criteria index, plus our response to the Sustainability Accounting Standards Board (SASB).

In addition, we track our non-financial performance internally on a quarterly basis. Our integrated reporting system consolidates cross-functional non-financial performance data at market, regional and global levels, giving senior internal stakeholders a clear view of our performance. This enables us to act early to amplify opportunities and address risks, ensuring we stay on track to deliver our Society 2030 goals. Non-financial reporting is a rapidly evolving area, so we are continually evaluating and developing our approach and we actively track emerging ESG frameworks and best practice.

Our aim is to ensure that between our Annual Report, the ESG Reporting Index and we provide the information our diverse stakeholders expect and need.


We engage independent auditors to provide limited assurance of environmental performance data (carbon emissions, water stewardship, biochemical oxygen demand (BOD), and waste to landfill), health and safety data and social impact data, relating to our inclusion and diversity ambitions and our underage drinking programmes.

Our Task Force on Climate-related Financial Disclosures (TCFD) reporting

We are committed to playing our part and championing policies that support the Paris Agreement. As such, we welcome the Task Force on Climate-related Financial Disclosures (TCFD) as an important step in increasing stakeholders’ and companies’ focus on climate change. We have incorporated the TCFD framework into our reporting and are accelerating efforts to mitigate climate change risks and identify opportunities for transitioning quickly to a low carbon future. As recommended by TCFD, we use climate change risk assessment and scenario analysis as tools through which to better understand the potential impact of climate risks on our business.

Please see the extracted section of our most recent Annual Report, Responding to climate-related risks, which uses the TCDF reporting framework.
