This is the thirteenth consecutive year that we have provided a Global Reporting Initiative (GRI) Report. 
During 2020, 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 2020 to 31 December 2020.

 
Our separately published 2020 Sustainability Report contains a significant amount of information relating to GRI content whilst some information can also be found in our 2020 Annual Report.
