Integrated Assessment of Mobility Systems

The central objective of Capacity Area B2 is to evaluate the future Swiss mobility system taking into account various economic, social and sustainability criteria (energy demand, pollutant and CO2 emissions, resource depletion, costs and user preferences). This includes an environ-mental, cost and risk assessment of different technology options for individual mobility as well as for public and freight transport. These results are fed directly into an energy-economic model to analyze long-term mobility scenarios in terms of costs, CO2 emissions and energy demand and to identify technology options to meet the objectives of the Swiss energy strategy. In addition, key factors affecting mobility behavior and demand are analyzed to formulate recommendations and guidelines to promote a socio-economic transformation of the Swiss mobility system.

Swiss TIMES Energy system Model (STEM) for transition scenario analysis

The Swiss TIMES Energy system Model (STEM) allows analyzing interactions between the energy and transport sector in Switzerland long term. The model evaluates car fleet scenarios with different shares of drivetrain technologies (internal combustion engine, hybrid, battery electric and fuel cells) with respect to their greenhouse gas emissions.
