ESG Report 2023

The absence of a significant body of established practice on which to draw to evaluate and measure non-financial information allows for different, but acceptable, measures and measurement techniques and can affect comparability between entities. Further, greenhouse gas quantification is subject to inherent uncertainty because of incomplete scientific knowledge used to determine emissions factors and the values needed to combine emissions of different gases. Inherent Limitation We conducted our verification under limited assurance engagement with reference to International Standard on Assurance Engagements 3000 (Revised), Assurance Engagements Other than Audits or Reviews of Historical Financial Information (“ISAE 3000 (Revised)”) issued by the International Auditing and Assurance Standards Board. The standard require that we plan and perform this engagement to obtain limited assurance about whether the Specified Performance Information is free from material misstatement. A limited assurance engagement undertaken with reference to ISAE 3000 (Revised) involves assessing the suitability in the circumstances of The United Laboratories’s use of applicable criteria as the basis for the preparation of the Specified Performance Information, assessing the risks of material misstatement of the Specified Performance Information whether due to fraud or error, responding to the assessed risks as necessary in the circumstances, and evaluating the overall presentation of the Specified Performance Information. A limited assurance engagement 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. Within the scope of our work, SHINEWING Sustainability performed amongst others the following procedures: • Interview the managers responsible for sustainability performance and data collection; Review the preparation process of the Specified Performance Information, including stakeholders engagement and materiality assessment; Verify the samples of the representative data and information selected, including review on conversion data and calculation as well as inspect the original data and supporting evidence of the data selected during the verification process; Perform analytical procedures over the Specified Performance Information; and Compare the definition as included in the Reporting Criteria against the definitions used by The United Laboratories to prepare the Specified Performance Information. • • • • Reporting Framework and Procedures Performed Based on the procedures that SHINEWING Sustainability has performed and the evidence we have obtained, nothing has come to our attention that causes us to believe that the Specified Performance Information is not prepared, in all material respects, in accordance with Reporting Criteria of the ESG Report.
