Reporting principles

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 2012.

Subsidies: The data of this indicator included 15 major Wärtsilä subsidiaries and the parent company in 2012.

Environmental performance data

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.

Heat and electricity data is based on either invoices or measured values.

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.

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.

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.
