We have provided independent limited assurance, in accordance with the International Standard for Assurance Engagements (“ISAE”) 3000 (Revised),1 on selected sustainability information (“subject matter”), for the financial year ended 31 December 2018. The subject matter is reported in the 2018 Sustainability Report (“SR”) of BP p.l.c. (“BP”).
The above subject matter has been assessed against BP’s Reporting Requirements and Definitions.6
To form our conclusions, we undertook the following procedures over the subject matter:
We believe that the evidence obtained is sufficient and appropriate to provide a basis for our limited assurance conclusion.
Based on our procedures described in this report, nothing has come to our attention that causes us to believe that the selected subject matter stated above, for the financial year ended 31 December 2018, as presented in BP’s 2018 SR, has not been prepared, in all material respects, in accordance with BP’s Reporting Requirements and Definitions.
We used the ISAE 3000 standard to carry out a limited assurance engagement. To achieve this, ISAE 3000 requires that we review the processes, systems and competencies used to compile the areas on which we provide assurance. This is designed to give a similar level of assurance to that obtained in the review of interim financial information. It does not include detailed testing of source data or the operating effectiveness of processes and internal controls.
Inherent limitations exist in all assurance engagements due to the selective enquiry of the information being examined. Therefore fraud, error or non-compliance may occur and not be detected. Additionally, non-financial information, such as that included in BP’s 2018 SR is subject to more inherent limitations than financial information, given the nature and methods used for determining, calculating, and sampling or estimating such information.
Our work has been undertaken so that we might state to BP those matters we are required to in this report and for no other purpose. Our work did not include physical inspections of any of BP’s operating assets.
While we acknowledge that this report will be published on the BP website, the maintenance and integrity of that website is the responsibility of BP. The work that we carried out does not involve consideration of the maintenance and integrity of that website and, accordingly, we accept no responsibility for any changes that may have occurred to this report and BP’s 2018 SR since they were initially presented on the website.
We complied with Deloitte’s independence policies, which address and, in certain cases, exceed the requirements of the International Ethics Standards Board for Accountants’ Code of Ethics for Professional Accountants in their role as independent auditors, and in particular preclude us from taking financial, commercial, governance and ownership positions which might affect, or be perceived to affect, our independence and impartiality, and from any involvement in the preparation of the report.
We have confirmed to BP that we have maintained our independence and objectivity throughout the year and that there were no events or prohibited services provided which could impair our independence and objectivity.
We have applied the International Standard on Quality Control 1 and accordingly maintain a comprehensive system of quality control including documented policies and procedures regarding compliance with ethical requirements, professional standards and applicable legal and regulatory requirements.
BP is responsible for the preparation of the sustainability information and statements contained within the 2018 SR. It is responsible for selecting appropriate KPIs with which to describe the entity’s performance, and establishing and maintaining appropriate performance management and internal control systems from which the reported information is derived.
Our responsibility is to independently express conclusions on the selected sustainability information subject matter as defined within the scope of work above to BP in accordance with our letter of engagement. Our work has been undertaken so that we may notify BP of those matters we are required to inform them of in this statement and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than BP for our work, for this report, or for the conclusions we have formed.
