In order to achieve the climate goals both at the EU level and as part of the climate and energy strategy of the federal state of Salzburg, diesel-powered vehicles in public transport and heavy-duty transport must be replaced by zero-emission vehicles. Both battery-electric and fuel cell-electric (FCE) vehicles are suitable for the transition to Zero Emission Mobility (ZEM). Which technology shall be used in which context and in which setting is addressed in this project. Building the infrastructure necessary to implement ZEM solutions in Salzburg's urban and alpine areas is a challenge that the ZEMoS project takes up.

As part of the project, two ZEM model regions in Salzburg are being developed for public bus transport and pilot projects for zero emission heavy-duty transport. Model region 1 is located in urban areas, in Tennengau. The second ZEM model region covers an alpine tourism area of ​​Salzburg, in Pinzgau. The two ZEM model regions complement each other as they place different requirements on the alternative mobility solutions in terms of time frequency, loading, altitude profiles, temperature, etc.
