This is the tenth consecutive year that we have provided a Global Reporting Initiative (GRI) Report.
During 2017, a review of the GRI General Disclosures and Specific Disclosures was conducted. As a result, we are reporting to a self-declared ‘Core’ accordance level for the reporting period 1 January 2017 to 31 December 2017.
Our separately published 2017 Sustainability Report
contains a significant amount of information relating to GRI content whilst some information can also be found in our 2017 Annual Report
