Performance and reports

As a responsible business we are continually looking to improve our performance and the service we provide our stakeholders. Annually we set ourselves ambitious targets, selected as a result of our materiality assessment to ensure we help support the UN Sustainable Development Goals. Each year we review our progress against these targets to ensure continuous improvement and an industry-leading approach. We share details of our performance in our annual responsible business report.
