Sustainability

Assurance statement

To the Board of Management of Wärtsilä Oyj Abp

We have been engaged by the Board of Management of Wärtsilä Oyj Abp (hereafter: Wärtsilä) to provide limited assurance on Wärtsilä’s Sustainability Information from the reporting period 1.1.–31.12.2009 presented in connection with the electronic Wärtsilä Annual Report 2009 (hereafter: the Report), and to perform an application level check on Wärtsilä's sustainability reporting.

The Sustainability Information subject to the limited assurance engagement includes the data and assertions presented in the “Sustainability” -section and its sub-sections in the Report, as well as the following sub-sections of the “Business” section: “Ship Power and Sustainability”, “Power Plants and Sustainability”, and “Services and Sustainability”. The Sustainability Information also includes data and assertions on product sustainability performance presented on selected and marked pages at www.wartsila.com.

The application level check refers to evaluation of the scope of Wärtsilä’s sustainability reporting, according to the application level guidelines defined by Global Reporting Intiative (www.globalreporting.org). The purpose of the application level check is to assess whether Wärtsilä has reported on its sustainability aspects as self-declared in the Report.

The Board of Management of Wärtsilä is responsible for the presented Sustainability Information as well as for preparing and presenting the Sustainability Information in accordance with the Sustainability Reporting Guidelines of the Global Reporting Initiative 3.0 (G3) and the declared application level. The Board of Management of Wärtsilä has approved the presented Sustainability Information.

Our responsibility is to carry out a limited assurance engagement and to express conclusion on the Sustainability Information subject to the assurance based on the work performed. It is also our responsibility to carry out an application level check, as described above, and to express our independent conclusion on Wärtsilä’s reporting application level.

We have conducted the engagement in accordance with the International Standard on Assurance Engagements (ISAE 3000): Assurance engagements other than audits or review of historical financial information, issued by the International Auditing and Assurance Standards Board. Amongst others, this standard requires that the assuring party possesses the specific knowledge, skills and professional competence needed to understand and review the information to be assured, and that the assuring party complies with the requirements of the IFAC Code of Ethics for Professional Accountants to ensure their independence.

The evaluation criteria used for our assurance are the Sustainability Reporting Guidelines of the Global Reporting Initiative 3.0 (G3).


The work performed in the engagement

Our assurance procedures are designed to obtain limited assurance on whether the information subject to the assurance engagement is presented in accordance with the Sustainability Reporting Guidelines of the Global Reporting Initiative 3.0 (G3) in all material respects. A limited assurance engagement consists of making inquiries, primarily of persons responsible for the preparation of the sustainability information presented, and applying analytical and other evidence gathering procedures, as appropriate. The evidence gathering procedures mentioned above are more limited than for a reasonable assurance engagement, and therefore less assurance is obtained than in a reasonable assurance engagement.


In our engagement we have performed the following procedures:

• Interviews with two members of senior management to reassert our understanding of the connection between Wärtsilä’s sustainability procedures and Wärtsilä’s business strategy and operations as well as sustainability objectives;

• An assessment of data management processes, information systems and working methods used to gather and consolidate the presented Sustainability Information, and a review of Wärtsilä’s related internal documents;

• Comparison of Sustainability Information to underlying rules of procedure, management and reporting systems as well as documentation;

• An assessment of the presented Sustainability Information against the GRI reporting principles;

• A review of the presented Sustainability Information, including the performance data and assertions, subject to the engagement, and an assessment of information quality and reporting boundary definitions;

• Testing of data accuracy and completeness through samples from the Group’s information systems and original numerical information received from Wärtsilä’s subsidiaries;

• Visits to two sites selected on the basis of a risk analysis taking into account both qualitative and quantitative information.


For the application level check we have performed the following additional procedures:

• An assessment of the presented sustainability aspects relevant to G3 reporting and referred to in the GRI content index of the Report, to determine, whether the requirements of the self-declared application level have been met. All the sections referred to in the GRI content index were included in this assessment, whether or not subject to assurance.

• An assessment of the Report against the GRI reporting principles

• Assessment of the accuracy of the GRI content index


Limitations of the engagement

Sustainability related data and information are subject to inherent limitations applying to data accuracy and completeness, which are to be taken into account when reading our assurance report. The presented Sustainability Information is to be considered in connection with the explanatory information on data collection, consolidation and assessments provided by Wärtsilä. Our assurance report is not intended for use in evaluating Wärtsilä’s performance in executing the sustainability principles Wärtsilä has defined. To assess the financial state and performance of Wärtsilä, the Wärtsilä audited Financial Statement for the year ended 31 December 2009 is to be consulted.

The sections of the Report included in the application level check were only considered from the sustainability point of view as relevant to G3 reporting guidelines. The information presented in the sections was not part of the assurance engagement, except when included in the Sustainability Information scope as defined above.


Conclusions

Based on the assurance procedures performed, nothing has come to our attention that causes us to believe that the information subject to the assurance engagement is not prepared, in all material respects, in accordance with the Sustainability Reporting Guidelines of the Global Reporting Initiative 3.0 (G3) or that Wärtsilä’s reporting does not correspond to the self-declared A+ reporting application level.
