Sustainability targets

Our sustainability targets express our focus areas and provide information on Wärtsilä’s performance. In 2021, we set new targets and made conceptual changes to our target setting. First, we switched from a fixed timeline to dynamic target setting. This allows us to re-evaluate the feasibility of the targets in case of major changes, and to add new targets when needed, on an annual basis. Secondly, we set targets under three long-term focus themes: Towards carbon neutrality, Enhancing safety, diversity and wellbeing, plus An active and responsible member of society.



OWN OPERATIONS: To become carbon neutral in own operations.


The Wärtsilä 'Set for 30' commitment was published in October 2021. It includes the carbon neutrality goal, which is based on a company-initiated analysis that identified the key measures for reaching the goal. The toolbox includes measures such as energy savings, green electricity purchases, switching fuels, the use of more efficient technologies, and the use of offsets for emissions hard to abate. A detailed implementation plan and timeline will be set in 2022.

OWN OPERATIONS: 100% renewable generated electricity purchases in Finland (relating to the Smart Technology Hub, STH).


In 2021, alternatives for purchasing green electricity were identified, and appropriate solutions were selected.

OWN OPERATIONS: Reduce energy consumption by at least 7% from 2015 levels in terms of absolute consumption (GWh). 


By the end of 2021, energy savings of 8.7 GWh were achieved, representing 29.2% of the final 2025 target.

PRODUCTS AND SOLUTIONS: To provide a product portfolio that will be ready for zero carbon fuels.


This target is part of the 'Set for 30' commitment published in October 2021. In 2021, work towards the target started with ammonia and hydrogen testing. The next steps are under development.

PRODUCTS AND SOLUTIONS: Hydrogen Proof of Concept testing – Finalise the first phase of testing with a demo on pure hydrogen.


In 2021, the first phase tests in pure hydrogen operation were completed successfully on a single cylinder engine (SCE).

PRODUCTS AND SOLUTIONS: Ammonia Proof of Concept testing – Finalise the first phase of testing with a demo on pure ammonia.


In 2021, the first phase testing with a test engine was successfully finalised using an ammonia/LFO blend content of up to 70%/30% and at a 75% engine load. The first tests on pure ammonia will be conducted in 2022.

PRODUCTS AND SOLUTIONS: Next DF pilot installation – Reduce methane slip by more than 50%, leading to greenhouse gas emission reductions of 10% from the current Best Available Technology (BAT) level.


In 2021, Wärtsilä proceeded with the laboratory testing and validation of a new combustion concept, which includes advanced closed loop combustion control, for our dual fuel (DF) engines. The concept achieves a 50% reduction in the amount of unburned fuel in the exhaust gas (methane slip) compared to today's technology, whilst also improving efficiency and load taking capability at part load. The new technology will become available for all latest generation DF engines, including the W31, W46TS and W25. The next and final step of the validation process will be field validation of the W31DF engine installed on the M/S Aurora Botnia.

PRODUCTS AND SOLUTIONS: Complete the first power-to-X and X-to-power demonstrator project.


A pre-engineering contract for a project with Vantaan Energia was signed and the project is under execution.

PRODUCTS AND SOLUTIONS: Enable greater deployment of renewables with an energy storage project capacity totalling 1,000 MWh.


In 2021, the deployed energy storage project capacity totalled 205 MWh, while the order intake was in excess of 3,000 MWh.



ENHANCING SAFETY: Reach the long-term goal of zero injuries.

Long-term target

In 2021, the corporate lost-time injury frequency rate (LTIF) was 1.55. This was below the annual target of 1.60, representing a 23% improvement over 2020 (2.03). During the year, implementation of the Xcel Safety 2022 programme progressed, including continuation of the front-line Champions in Safety training programme and initiation of the equivalent training for Wärtsilä leaders. In addition, the Safehands campaign was delivered resulting in a 50% reduction in hand injuries compared to 2020. The theme of Safety Day 2021 was Every Step Matters, which highlighted the importance of avoiding slips, trips, and falls. Wärtsilä recorded a remarkable increase in the reporting of preventive safety measures, while the number of management safety walks increased by 44%, and near miss/hazard reporting by 3% compared to 2020.

ENHANCING SAFETY: Establish a contractor EHS (environmental, health & safety) compliance programme including requirements, implementation, consultation, auditing, measuring, target setting, and reporting.


Contractor EHS was a focus area within the management system audit during 2021. A cross-business project team was formed to co-ordinate the development and initiation of the contractor EHS compliance programme.

ENHANCING SAFETY: Implement an enhanced safety philosophy at the Smart Technology Hub.


The new facilities are designed to support an optimal flow of materials and safe operations at all times. The production automation level has been increased in all areas, and safety was improved by minimising the manual handling of components. The new testing facilities are planned with improvements from an occupational safety, chemical, and fire safety point of view, and will be equipped and taken into use during 2022. To enable an enhanced safety mindset, the focus has been put on training and the induction of personnel moving to the Smart Technology Hub. The 100% Safety concept is being implemented – we focus on doing work safely all the time and learn from safety success. The leaders' commitment to this is emphasised by increased safety communication during meetings and safety walks. To further improve the adoption of the new safety concept, increased attention will be given to the visualisation of safety in the new facilities.

WELLBEING AND DIVERSITY: Achieve an employee engagement index above 80%.


The latest Wärtsilä global engagement survey, MyVoice, was conducted in October 2020 with an employee engagement index score of 72.7%. The next global engagement survey is scheduled during 2022.

WELLBEING AND DIVERSITY: Personnel development – reach 100% Development Discussion completion rate.


By the end of 2021, altogether 91% of the company’s employees had completed development discussions.

WELLBEING AND DIVERSITY: Diversity – increase the share of females in the workforce to 20%.


In 2021, the share of female employees was 17.4%.

WELLBEING AND DIVERSITY: Reach equal pay for males and females as specified (100%).


During 2021, we achieved 100% equal pay for males and females*.

*Based on active employees, converted into 1FTE (full-time equivalent, 100% working time), excluding trainees and top management



Achieve a Code of Conduct training coverage of 100% to ensure commitment to the Code of Conduct throughout the organisation.


As at the end of 2021, the Code of Conduct training coverage was 94% of all employees.

Prepare new content for the ethical discussions programme


The planning of a new programme started during 2021 with the identification of new themes.

Launch of an enhanced anti-corruption training programme


In 2021, the anti-corruption policy was reviewed. The enhanced training programme will be planned and launched during 2022.
