We update our sustainability performance on an annual basis. Our approach to sustainability reporting includes Our Beer Print Report, which shows progress towards our 2025 goals, and a separate Environmental, Social and Governance (ESG) report, which details our 2017 performance and links to our website to provide more real-time updates about our sustainability journey. The 2018 GRI Index can be found here .
Our reporting maintains our commitment to align with international reporting frameworks. We also report to the Carbon Disclosure Project and the Dow Jones Sustainability Index (DJSI). Assurance of the data contained within our ESG report has been carried out by Corporate Citizenship in accordance with ISAE3000.
