Independent Assurance report
To: The Board of Directors and Management of Suncor Energy Inc. (“Suncor”)
What we looked at: Scope of our work
We have reviewed selected corporate-wide and business unit performance indicators, as further described
in the addendum below, for Suncor's Report on Sustainability for the year ended December 31, 2013 (“the
Report”). We did not review all information included in the Report. A review does not constitute an audit
and, consequently, we do not express an audit opinion on the selected performance indicators.
Responsibilities
Suncor management is responsible for the selection and presentation of the indicators and information set
out in the Report. We did not review all information included in the report, except where they
incorporated the selected performance indicators. Our responsibility is to express an independent
conclusion on whether anything has come to our attention that causes us to believe that the selected
performance indicators are not presented fairly, in all material respects, in accordance with the Global
Reporting Initiative (GRI) G3.1 Sustainability Reporting Guidelines.
What we did: Assurance standards and key assurance procedures
We conducted our review in accordance with the International Standard on Assurance Engagements
(ISAE) 3000 developed by the International Federation of Accountants. As such, we planned and
performed our work in order to provide limited assurance with respect to the selected performance
indicators that we reviewed. Our review criteria were based on the GRI G3.1 Sustainability Reporting
Guidelines. Our procedures included:
•
Interviewing relevant Suncor management and staff responsible for data collection and reporting;
•
Obtaining an understanding of the management systems, processes and the relevant controls used to
generate, aggregate and report the data at Suncor’s regional operations and head office;
•
Reviewing relevant documents and records on a sample basis;
•
Testing and re-calculating information related to the selected performance indicators on a sample
basis; and,
•
Assessing the information for consistency with our knowledge of Suncor’s operations, including
comparing the Suncor’s assertions to publicly available third-party information.
Environmental and energy use data are subject to inherent limitations of accuracy given the nature and the
methods used for determining such data. The selection of different acceptable measurement techniques
can result in materially different measurements. The precision of different measurement techniques may
also vary.
