In order to demonstrate to our stakeholders that we are a sustainable and well-managed company – and proactive in terms of addressing the social and environmental issues that matter to them – we are committed to subjecting relevant aspects of our corporate responsibility programme to processes of independent audit and assurance.

CR reporting

The commentary and data contained within this report is independently assured by Corporate Citizenship. This is done to reassure stakeholders that our CR management systems, processes and procedures are well managed and in accordance with legislation and best practice. It also provides reassurance that our reports and any data we disclose are accurate, complete and material.

The assurance provided to our CR report evaluates the nature and extent of adherence to the AccountAbility AA1000 Assurance Standard (AA1000AS) principles of inclusivity, materiality and responsiveness. In addition, the content and quality of the information in the report is evaluated against the Global Reporting Initiative's G3 sustainability reporting guidelines.

Environmental management

Our environmental management system is also audited against the requirements of the international standard ISO 14001. This audit work has been carried out by the consultancy firm SEQM since 2006.
