To the management of Statoil ASA
Scope of Engagement
We have been engaged by the corporate executive committee of Statoil ASA to perform an independent assurance of the Sustainability Report (“the Report”) as presented in the section “Sustainability” in the Statoil Annual and Sustainability Report 2011.
We have also been engaged by the corporate executive committee of Statoil ASA to prepare an independent assurance report on the health, safety and environment (HSE) accounting for Statoil ASA in 2011, as presented in the section “HSE accounting” and in the sub-sections "HSE performance indicators" and "Environmental posters" in the Report, in its online and downloadable pdf format.
The scope of our assurance engagement extends only to the content of the Report as determined by the Company, subject to the limitations the Company defines in the chapter “The boundaries of our reporting”.
The content of the Report that is within the scope of our procedures is marked with a label that confirms it has been subject to assurance by Ernst & Young. Our scope only includes the content of other parts of the Annual and Sustainability Report 2011 to the extent that they are referenced to from within the “Sustainability” chapter and excludes all content referred to from external sources.
As a basis for the HSE assurance engagement, we have used Statoil ASA’s internal reporting criteria specifically developed for HSE (HSE01.01 “Reporting and performance management"), described in the section “HSE accounting” in the Report, together with relevant criteria in the sustainability reporting guidelines of the Global Reporting Initiative (GRI G3). For the sustainability assurance engagement, we have used relevant criteria in the GRI G3 sustainability reporting guidelines. We consider these reporting criteria to be relevant and appropriate to review the Report.
The management’s responsibility
Statoil ASA’s management is responsible for the HSE accounting and the sub-sections "HSE performance indicators" and "Environmental posters”. It is also responsible for selecting the information, collecting the data for presentation and preparing the Report. The choices made by the management, the scope of the Report and the reporting principles, including the inherent specific limitations that might affect the reliability of the information are explained in the section “The context of our reporting”
The auditor’s responsibility
Our task is to issue a statement on Statoil’s 2011 Sustainability Report and Statoil’s 2011 HSE accounting on the basis of the engagement outlined above. The content verified by us is marked with a text confirming the assurance engagement.
Assurance standards used and level of assurance
We have performed both assurance engagements in accordance with the ISAE 3000, “Assurance engagements other than audits or reviews of historical financial information”. The standard requires that we plan and execute procedures in order to obtain the following assurance levels:
- Reasonable assurance that the information in the section “HSE accounting” is, in all material respects, an accurate and
adequate representation of Statoil’s HSE performance during 2011
- Reasonable assurance of the reliability of the consolidation process for the key performance indicators included in the HSE accounting and environmental posters
- Limited assurance that the other information in the Report is, in all material respects, an accurate and adequate representation of
the policy with respect to sustainability, business operations and events during 2011. The procedures performed in order to obtain limited assurance aim to verify the plausibility of information and probe less deeply than those performed for assurance engagements aimed at obtaining reasonable assurance.
Assurance procedures for the HSE accounting
Our assurance of the HSE accounting, including the sub-sections “HSE performance indicators” and “Environmental posters”, is performed in accordance with the ISAE 3000 (reasonable assurance). The standard requires that we plan and execute procedures in order to obtain reasonable assurance that the HSE accounting as a whole is free of material misstatement.
Our work on the HSE accounting assurance has included:
- Discussions with the corporate management for HSE on the content and aggregation of the HSE accounting
- Site visits to selected entities, chosen based on an evaluation of the entity’s nature and significance, as well as general and specific risks. During site visits we have interviewed managers and personnel
who participate in collecting the figures for the HSE accounting
- Testing, on a sample basis, to evaluate whether HSE data which are included in the corporate performance indicators and environmental posters are reported, registered and classified according to Statoil governing documents and in line with referred or recognized standards and methods
- Review of whether systems used for registering, adapting, aggregating and reporting are satisfactory, and evaluating whether the reporting is complete and that the collection of data, adaptation and presentation of results in the HSE accounting is consistent
- An overall analysis of the figures compared with earlier reporting periods
- Assessment of whether the overall information is presented
in an appropriate manner in the HSE accounting.
We have evaluated the HSE data’s reliability, and whether the HSE performance is presented in an appropriate manner. Our objective has been to investigate:
- The acceptability and consistency of the reporting principles
- The reliability of the historical information presented in the HSE accounting section of the Report
- The completeness of the information and the sufficiency of the presentations
We believe that our procedures provide us with an appropriate basis to conclude with a reasonable level of assurance for Statoil’s HSE accounting.
Assurance procedures for the Sustainability Report
Our assurance of the Report has been planned and performed in accordance with ISAE 3000 (limited assurance). The standard requires that we plan and execute procedures in order to obtain limited assurance on the Report.
Our review of the Report has involved the following activities:
- Interview with a representative from Statoil’s executive management and visits to three entities, as a representative sample of Statoil’s variety of
activities, to gain an understanding of their approach to managing social, ethical and HSE issues that are covered in the Report
- Obtaining and considering evidence to support the assertions and claims made in the Report
- Evaluation of the overall presentation of the Report, including the consistency of the information, based on the above-mentioned criteria
- In-depth evaluation of two selected content areas of the Report,
including data quality and compilation for this year’s report
- Evaluation of the overall materiality, balance and consistency of the information in the Report.
- Media research in relation to press articles about the company and its activities throughout the calendar year.
On the basis of our procedures aimed at obtaining reasonable assurance, we conclude that in our opinion:
- The information in the HSE accounting presented in the section “HSE accounting” of the Report is, in all material respects, an accurate and adequate representation of the policy and management with respect to HSE accounting during 2011, and that the HSE accounting includes information on all matters relating to HSE which are relevant to the Statoil group as a whole
- The consolidation process that underlies the HSE performance indicators was, in all material
respects, performed in a reliable manner, and that the information presented is consistent with the stated criteria
- The HSE performance indicators and environmental posters are in accordance with information submitted by the various entities, and illustrations of trends are in accordance with presented historical data
On the basis of our procedures aimed at obtaining limited assurance, nothing has come to our attention that causes us to believe that the information in the Report does not comply with the above mentioned reporting criteria. This also counts for Statoil’s declaration that the Report meets the requirements of the A application level of the GRI G3 sustainability reporting guidelines.
