Economic performance data
The economic performance data is based on audited financial accounting and covers all Wärtsilä subsidiaries unless otherwise stated.
Donations: The data of this indicator included 15 major Wärtsilä subsidiaries and the parent company in 2014.
Subsidies: The data of this indicator included all Wärtsilä subsidiaries and the parent company in 2014.
The social costs for employees contribute to the funding of pensions, unemployment and other social benefits that provide security and improve the quality of life for the company's employees and their families.
Senior management includes all employees with the highest job grade levels 10–15. At the end of 2014 this covered 466 employees.
Environmental performance data
Materials include all the major material flows used in the production processes globally. The most material consuming product categories include engines, propellers and propulsion systems.
Total energy consumption includes both direct and indirect energy usage. The direct energy usage includes the fuels used by Wärtsilä subsidiaries. The indirect energy usage includes the purchased electricity and heat. Since the efficiency of purchased electricity and heat generation is not known, the energy conversion is done directly from the purchased values. Lower heat values (LHVs) of fuels are used to calculate the energy consumption in Joules. LHVs are based on results of fuel analysis.
Heat and electricity data is based on either invoices or measured values.
Energy intensity describes the ratio of total internal energy consumption divided by the net sales of the subsidiaries included in the data gathering in particular year.
GHG emissions intensity describes the ratio of total greenhouse gas emissions divided by the net sales of the subsidiaries included in the data gathering in particular year.
Reduction of energy consumption data is based on energy efficiency actions, which are based on the results of third-party energy audits. Energy audit reports include proposed energy saving actions with calculated energy saving potentials per action item.
Water consumption: The reported figures are based on either measured values or invoices. The cooling water usage might also be calculated from the heat load in some units.
Recycled water: The reported amount is the total measured recycled water used in Wärtsilä Italia S.p.A. Their water treatment plant provides reusable water for manufacturing processes.
Water consumption: The reported figures are based on either measured values or invoices. The cooling water usage might also be calculated from the heat load in some units. The water sources have been specified based on a detailed questionnaire for each Wärtsilä subsidiary.
Water discharge: The reported figures are based on either measured values or invoices. The cooling water discharge might also be calculated from the heat load in some units. The water discharge destinations have been specified based on a detailed questionnaire for each Wärtsilä subsidiary.
Emissions: The reported figures are mainly based on measured values, based on which specific emission factors are determined. The specific emission factors are determined for various fuels and engine types. The emissions of the heating boilers are either measured or calculated. The emissions of vehicles are calculated by using the VTT (Technical research centre of Finlands) Lipasto database emission factors. The indirect CO₂ emissions (scope 2) are calculated by using the emission factors from the GHG Protocol. The CO₂ emissions of air travel are based on calculations by Wärtsilä's travel agency and are based on DEFRA (the UK government Department for Environment, Food and Rural Affairs) defined factors. GWP factor used for converting methane emissions to CO₂-equivalent is 25.
Environmental hazards: As such are considered major incidents, which generally require communication to local authorities.
Social performance data
Injuries: The reported figures include all types of reported cases other than lost time injuries.
Lost time injuries: The reported figures include all the reported injuries resulting in absence from work of at least one day.
LTI frequency is expressed as reported lost time injuries per million working hours. The working hours are actual paid working hours. The lost time injury rate does not include commuting injuries.
Employee turnover is calculated from permanent employees. The number of resigned permanent employees is divided by the headcount of permanent employees at the beginning of the reporting period.
