Electric buses at the forefront of our emission reduction goals

Electric buses do not produce local emissions or greenhouse gas emissions, which is why they are essential to achieving our goal of cutting emissions from public transport in the Helsinki region by more than 90% by 2025, compared with 2010 levels.

Our goal is for public transport in the Helsinki region to be completely emission-free by 2035.

In 2024, a total of 547 electric buses were in service in the region. In 2025, around half of the bus services we procured were operated with electric buses, corresponding to approximately 650 buses.

The electricity used by electric buses must be sustainably produced in the Nordic countries, for example, from wind, hydro or solar power.

Electric buses also provide another significant benefit: they are quiet and smooth, with lower noise and vibration levels than diesel vehicles.

The Clean Vehicles Directive paves way for more electric buses

We favor electric buses in our tendering processes

The most important means for us to ensure that the number of electric buses keeps increasing is to favor electric vehicles in our competitive tendering of bus services.

We set a minimum limit for annual route kilometers of tendered bus services that must be operated using electric vehicles.

In addition, many bus operators offer to use electric buses unprompted. Even though electric buses cost more than diesel buses, having an electric fleet is a competitive option compared to buses equipped with internal combustion engines.

Costs incurred from operating and maintaining electric buses are smaller compared to those of diesel buses.

Ethical manufacturing of batteries is a priority

As of 2020, we have monitored the manufacturing of batteries for electric buses in our tendering processes from an ethical point of view. We require that the manufacturer of the electric bus include in their bid a report on the environmental effects of the batteries during their lifecycle as well as whether the batteries were manufactured under ethical conditions.

We work in cooperation with other Nordic public transport authorities to develop the life-cycle assessment of electric buses. The goal is to account for emissions caused by the manufacturing of electric bus batteries in the life-cycle assessment in order to take them into consideration in future tenders.

Our work for the environment is yielding results

Our long‑term work for the environment is already delivering clear reductions in emissions from bus services and other public transport. And the journey continues.
