About sustainability reporting

The non-financial data and information included in Tieto’s Annual Report 2017 are prepared in accordance with the core option of the GRI Standards. The disclosures focus on the sustainability topic that are considered to be the most material regarding Tieto’s economic, social and environmental performance.

Tieto’s material sustainability areas were identified during a materiality analysis in 2016–2017. These areas are the focus of our Corporate Responsibility 2020 plan.

The sustainability disclosures include the Parent company Tieto Corporation and all subsidiaries over which the Parent company has direct or indirect control. The GRI General Disclosures cover the entire Tieto Group.

Unless otherwise stated, all information and data pertain to activities from 1 January to 31 December 2017. The regional data is divided between HR and financial data due to system restrictions.

Unless otherwise stated, Tieto’s energy reporting and corresponding Scope 1 and 2 emissions cover all operating sites (offices, laboratories and data centres). The scope of the energy data collection was aligned with our Environmental Management System; data is collected from data centres, laboratories and offices with 50 employees or more. The energy consumption of offices with <50 employees was estimated based on our global average values with a 10% safety margin. The original data sources are internal IT systems and invoices from utility providers.

The scope 2 CO2 emissions were restated as a result of separating the energy fed from the data centres back into the district heat network. It is now reported under avoided energy and thus aligned with the GHG protocol.

Energy and emission calculations follow the Greenhouse Gas Protocol, and emissions are reported as CO2 emissions. Some calculations are manually conducted. The source of the indirect, location-based energy emission factors is the International Energy Agency (IEA). The base year emissions for the scope 2 reporting were updated using three-year average factors for all years. The sources for indirect, market-based energy emission factors are energy companies for the actual factors. Residual mix factors are used for the EU and the IEA factors are used for non-EU countries with no actual market-based factors. For direct energy, DEFRA’s emission factor is applied.

The scope 3 business travel related CO2 emissions include flights and the use of own cars. The CO2 factors used are DEFRA for flights and VTT Lipasto for car use. The data was collected from the company IT system and service providers. Locations with major operations and a significant amount of travel are within this scope.

In addition, energy consumption from leased assets are reported under the scope 3 emissions for the first time. The CO2 factor used for electricity consumption is market-based.

The base year for the Scope 1–3 environmental calculations is 2016, but a three-year trend extending to 2015 is reported. In the report, the metric ton/UK tonne equivalent to 1 000 kilograms is stated solely as a ton.

The CO2 calculation model for Sustainable IT services was renewed. The baseline for the new model was chosen to be 2017. The new model is not comparable with previously reported CO2 avoidance.

Unless otherwise stated, our workforce related figures in the Sustainability section of the report are based on the GRI Standards. The numbers include joint ventures, hence differing from the headcount in the Financial section. The data sources are company systems which provide data on full-time, part-time, permanent and temporary employees.

An independent third party, PricewaterhouseCoopers Oy, have provided their assurance on the corporate responsibility information disclosed in Tieto’s Annual Report 2017. The scope of the assured information is indicated in the independent practitioner's assurance report. In our view, third-party, independent assurance increases transparency and is key to delivering a high-quality report.

This report is also our annual Communication on Progress in accordance with the UN Global Compact requirements. It qualifies for the GC Advanced level.

Our Corporate Responsibility Report 2016 was published on 1 March 2017.
