Independent Assurance Report – Outotec Sustainability Report 2017

To the Management of Outotec Oyj

Insinööritoimisto Ecobio Oy (hereafter Ecobio) has been commissioned by Outotec Oyj (hereafter Outotec) to perform a limited third party assurance engagement regarding the content of Outotec’s Sustainability Report for 2017.

Outotec’s Responsibility

Outotec was responsible for the collection, preparation and presentation of the information in the Sustainability Report (hereafter Sustainability Information) according to GRI Sustainability Reporting Standards (GRI Standards) set up by the Global Reporting Initiative (GRI). Ecobio, as an independent assuror was not involved in the data gathering and preparation of the Sustainability Information, apart from the Independent Assurance. The Management of Outotec has approved the information provided in the Sustainability Report.

Practitioner’s Responsibility

Ecobio’s responsibility was to present a conclusion on the Sustainability Information subject to the assurance performed by Ecobio.

The scope of work included assurance of completeness and correctness of information presented by Outotec in the Sustainability Report 2017. The assurance engagement was limited to the non-financial performance data disclosed in the Sustainability Report for the reporting period of January 1st 2017 to December 31st 2017. 

The Sustainability Information assured covered the Standard Disclosures in accordance with the core-level option, including the reported Environmental and Social Performance Indicators. In addition, the level of the consistency of the Economic Performance Indicators reported was checked against the GRI Standards.

Ecobio disclaims any liability or responsibility for any third party decision based upon this assurance report.


Ecobio based the assurance process on the following guidelines and standards: the GRI Sustainability Reporting Standards, the International Standard on Assurance Engagements (ISAE) 3000 (Revised) Assurance Engagements Other than Audits or Reviews of Historical Financial Information and Outotec’s internal reporting guidelines. The assurance process was performed utilizing Ecobio’s internally developed GRI assurance tool, covering the principles, standard disclosures and indicators of the GRI Standards. The Standard Disclosures were assessed based on a sampling plan composed by Ecobio. 

Concerning limited assurance engagement the evidence-gathering procedures are more limited than for a reasonable assurance engagement, and therefore less assurance is obtained. This assurance engagement was conducted from January 2018 to March 2018. The assurance process included:

  • Interviewing employees responsible for data collection and reporting at Outotec’s group level.
  • Evaluating procedures for gathering, analyzing, and aggregating quantitative data for the Sustainability Report 2017 as well as performing cross-checks on a sample basis concerning the reported sustainability data.
  • Checking the internal guidelines of the data collection.
  • Checking the sufficiency of the documentation of the data gathering process.
  • Checking the consistency of the Sustainability Report 2017 compared to the GRI Sustainability Reporting Standards.


Based on the work described in this report, nothing has come to our attention that would cause us to believe that the information presented in Outotec’s Sustainability Report 2017 is not fairly stated, in all material respects, or that it would not comply with the Reporting Criteria stated before.

Observations and Recommendations

Based on our limited assurance engagement we provide the following observations and recommendations related to GRI Sustainability Reporting principles. These observations and recommendations do not affect the conclusions presented earlier.

  • In general, the report is comprehensive, well-structured and claims are reported in a clear and reasonable fashion.
  • Outotec presents a good understanding of sustainable development conditions and the reported strategy and performance relate to the understanding of these conditions.
  • The materiality assessment is comprehensive taking into account different dimensions of sustainability. The process for defining the report content could though be described more in detail.
  • All relevant topics are covered in the report and a shift to a more focused content has been made during previous years. However, attention should be paid that if omissions are made they are clearly stated in the GRI content index.
  • For upcoming years, it is recommended to further elaborate on the magnitude of Outotec’s impact on specific phenomenon, which would improve the readers’ understanding of Outotec’s performance in the broader context of sustainability.
  • Stakeholder dialogue is active and relevant topics are well identified. We recommend keeping an active dialogue with stakeholders to maintain a high level on inclusivity in future reporting periods and to ensure that also future reports responds to stakeholder expectations and interests.
  • Outotec has made further progress on including the whole value chain within the reporting boundary, which is consistent with the work done during previous reporting periods. This could still be enhanced to even more comprehensively cover impacts outside the organization, as most of the impacts are identified to happen there. This would improve the completeness of the report.
  • The documentation of the work processes and the internal guidelines for data gathering have been significantly improved over time. It is recommended for further development to continue with the implementation of the guidelines in the organization. It is important that the organization is aware of exiting internal guidelines to achieve a robust and consistent reporting procedure.
