The metro is an energy-efficient and climate-friendly mode of transport, which can quickly transport large number of passengers. Because of this, the metro line will also be extended towards the west over the coming years. The introduction of the Western Metro will significantly reduce carbon dioxide emissions and improve air quality near Länsiväylä in Espoo and western Helsinki.
The automation of the metro will further improve energy-efficiency. For example, acceleration and braking can be optimised to be as efficient as possible. The metro’s energy consumption per kilometres driven has also been reduced with the use of an icebreaking and melting machine nicknamed ‘The Ice Walrus’ (‘Jäämursu’). This machine keeps the base of the conductor rails free of snow and ice and helps metro trains travel smoothly during the winter.
The central objective of the City of Helsinki environmental policy is to make Helsinki carbon neutral by 2050. Increasing metro traffic plays an important role in achieving this goal.
The metro has repeatedly received good grades in customer satisfaction surveys, as have the trams.
HKL Metro Transport runs the metro trains of Helsinki on behalf of HSL Helsinki Region Transport. Approximately 65 million passengers use HKL’s metro services annually.
From an environmental perspective, the metro is an efficient mode of transport. Metro traffic has the lowest energy consumption per kilometre of all modes of urban transport.
The energy, water and chemical consumption of the metro depot are monitored and unnecessary energy and water loss is prevented with regular maintenance. The train washing machine recycles some 85% of the water it uses: This saves a significant amount of clean water.
