Decarbonisation of the transport sector


As part of this project we are looking for ways to minimise greenhouse gas emissions from the transport sector by 2050 with the most favourable economic effects for Switzerland.

Project description (ongoing research project)

Using a mix of quantitative and qualitative methods we are examining the ways in which the transport sector can drastically reduce its greenhouse gas emissions by 2050. Initially, we will collect data from previous research and from discussions with various experts during workshops to look for options and measures for reducing greenhouse gases in the transport sector. We will then develop a range of scenarios for successfully reducing emissions in the transport sector by 2050, and calculate the economic effects for Switzerland (change in employment, GDP) with an economic equilibrium model. From these results and in dialogue with experts and based on an optimisation concept we will create a path that will show over time how a new approach to mobility can be economically viable.


The transport sector contributes heavily towards greenhouse gas emissions and – unlike industrial facilities or buildings – is not yet on a downward trend. The technical and political debate on greenhouse gas-free mobility in Switzerland is still in its infancy. Specific measures have so far not been clearly defined and the effectiveness and impact of many possible measures remain unclear.


With this study we want to find a viable means for the transport sector to minimise greenhouse gas emissions in economically and socially friendly ways by 2050. The project will initially show the significance of the transport sector for overall greenhouse gas emissions. We will then determine the potentials of possible measures for reducing emissions from transport and examine their impact on the Swiss economy and society. The aim of the study is to identify the opportunities and risks of different emission reduction scenarios in the transport sector, taking account of the agreed climate objectives for Switzerland, and to determine an environmentally, economically and socially friendly path.


Our study complements the specific scientific bases in the transport sector on which political decisions can be formulated so that Switzerland can make its contribution towards the objectives of the Paris Convention on Climate Change and the 2030 Agenda for Sustainable Development Goals.

In addition, this project will help close a research gap concerning quantitative impact analyses of possible scenarios so that a drastic reduction in greenhouse emissions in the transport sector can be achieved that is most viable for the environment, economy and society. The envisaged dialogue with experts in the project will provide an opportunity for an exchange of knowledge.
