* The recycled material input of metals varies between 20% and 95%, depending on the type of furnace and foundry used by the metal recycling companies in the supply chain.

** From 2024, the figure includes renewable district heat. Until 2021, renewable electricity consumption was included in purchased electricity category. 

*** Until 2022, Scope 3 emissions included purchased goods and services, energy and flights. In 2023, emissions from transportation and distribution were included and from 2024 the category Use of sold products is part of the Scope 3 emissions.

Water (GRI 303-3 - 303-5)

Wärtsilä’s water consumption can be divided into two categories: domestic use and cooling use. Domestic water is mainly used for sanitary purposes and by industrial equipment, such as machine tools and washing machines. Wärtsilä uses seawater for its engine and process cooling needs. In 2024, out of Wärtsilä’s total water withdrawal, about 99% was seawater for cooling purposes, 1% was from municipal water supplies, and about 0.2% was directly withdrawn groundwater or rainwater. 

In 2024, approximately 54,500 m³, amounting to 0.2% of all water withdrawal took place in high water stress areas in accordance with the WRI Aqueduct classification.

Wastewater is either piped to the local wastewater treatment plant or treated on-site before being discharged. If the effluent is not suitable for discharge, it is transported to an appropriate processing facility, such as a hazardous waste treatment plant. Several Wärtsilä subsidiaries have environmental permits that allow the discharge of clean or properly treated water into natural water bodies. Most of this discharge consists of clean cooling water, which is released back into local surface watercourses, releasing only heat. Since 99% of Wärtsilä's water withdrawal is for cooling purposes and is released back into local surface watercourses, Wärtsilä's operations do not consume any water.

Water data covers all Wärtsilä companies. Data is reported in Wärtsilä’s sustainability reporting tool and is based on either invoices or measured values, with the exception of less than 0.5% of total water data estimated.

Waste (GRI 306-3)

The waste figures are reported above. The data covers all Wärtsilä companies, is reported in Wärtsilä’s sustainability reporting tool and is based on either invoices or estimation.

Waste management in Wärtsilä has four aims, listed in their order of priority:

• to reduce the amount of waste generated in processes

• to use waste as a material

• to use waste as energy

• to dispose waste in an environmentally sound way

Wärtsilä’s upstream waste impacts are related to the production and transportation of parts, components, and products to our locations and customer sites. The overhaul services and lifecycle upgrades that Wärtsilä provides to its customers extend the useful life of the equipment, thereby reducing the need for complete product disposal and the generation of waste downstream in Wärtsilä’s value chain.

In 2024, the increase of emissions is due to the ramp down of manufacturing in Trieste, Italy and the related decommissioning of the production facilities.
