Practitioner’s responsibility
Our responsibility is to perform an assurance limited engagement and to express a conclusion on the Selected Indicators 2023 (including the GHG statement). We conducted our engagement in accordance with the International Standard on Assurance Engagements (ISAE) 3000 (Revised) ‘Assurance engagements other than audits or reviews of historical financial information’ and the International Standard on Assurance Engagements 3410, Assurance Engagements on Greenhouse Gas Statements (‘ISAE 3410’), issued by the International Auditing and Assurance Standards Board. Those standards require that we plan and perform our procedures to obtain limited assurance whether anything has come to our attention that causes us to believe that the Selected Indicators 2023 (including the GHG statement) were not, in all material aspects, prepared in accordance with the suitable Criteria.
Based on risk and materiality considerations, we performed our procedures to obtain sufficient and appropriate assurance evidence. The procedures selected depend on the assurance practitioner’s judgement. A limited assurance engagement under ISAE 3000 (Revised) and ISAE 3410 is substantially less in scope than a reasonable assurance engagement in relation to both the risk assessment procedures, including an understanding of internal control, and the procedures performed in response to the assessed risks. Consequently, the nature, timing, and extent of procedures for gathering sufficient appropriate evidence are deliberately limited relative to a reasonable assurance engagement and therefore less assurance is obtained with a limited assurance engagement than for a reasonable assurance engagement.
