What will Switzerland look like in the future? A welfare state in a just world, or an energy guzzler within Fortress Europe? Based on five scenarios, we examined for the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) how various political and social developments will affect greenhouse gas emissions up to 2100.
The modelling clearly shows how significantly different policy frameworks affect energy consumption and emissions:
We are already making decisions today about how climate change will transform our world. But what assumptions about the future are we basing these on?
The scenarios used here were developed conceptually by the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) based on the European Shared Socioeconomic Pathways (SSP).
Building on this, Prognos, together with INFRAS, calculated greenhouse gas emissions. In doing so, we took into account emissions from:
We also examined the impacts on land use and assess the effects of various economic and environmental policy decisions. Zoï Environment Network supported the processing and communication of the results.
These aspects were particularly helpful to the client in this project:

The COVID-19 pandemic and the war in Ukraine have shown just how much the emission of climate-damaging greenhouse gases also depends on social factors – factors that, at first glance, appear to have nothing to do with energy. Modelling various social, political and economic trajectories can therefore help policymakers to identify risks and make long-term strategic decisions.
Our study focuses on exploratory scenarios that do not provide forecasts, but rather depict a range of plausible futures in the form of if-then relationships.
The project is based on the following socio-economic development pathways (SSPs), which were identified by the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL):
1. Frugal Switzerland: In this scenario, the common good is highly valued by the Swiss population. Trust in political institutions is also high. The population consciously chooses a low level of consumption. The financial standard of living declines. Income and wealth are distributed evenly across society. Regional centres and urban neighbourhoods provide good basic regional services. The degree of self-sufficiency in energy and food is high.
2. Efficient Switzerland: In this scenario, Switzerland is highly technologised and has developed into an efficient circular economy with strong international integration. The population benefits from the value creation of a growing economy. Constant immigration leads to highly densified cities. Land consumption rises moderately, whilst environmental awareness among the population is very high. The supply of renewable energy is secure, largely domestic and partly imported.
3. Conflict-ridden Switzerland: In this scenario, Switzerland experiences political polarisation, corruption and a decline in prosperity. Investment and innovation are in decline and the economy is shrinking. Unemployment and emigration are rising, and companies are closing down or relocating. The welfare state is being dismantled. International relations are severely curtailed, and Switzerland is becoming increasingly isolated.
4. Unequal Switzerland: In this scenario, Swiss society is divided. An elite dominates economic and political affairs. This elite is well-connected internationally and maintains a resource-intensive lifestyle. Thanks to productivity-boosting technologies, the economy grows until the end of the century. The resulting productivity gains mainly benefit the elite, whilst job opportunities for the middle class are increasingly disappearing or shifting to the low-wage sector.
5. Resource-intensive Switzerland: In this scenario, Switzerland experiences strong economic growth and high levels of immigration. The increasing consumption of fossil fuels, combined with resource-intensive lifestyles, places a heavy strain on the environment. Towards the end of the century, rising resource prices and the costs of environmental degradation lead to declining economic output and a loss of prosperity.
All the scenarios examined in the project are exploratory. They do not describe target pathways and do not assign probabilities of occurrence. The modelling covering the period up to 2100 is subject to uncertainties, but allows for a systematic and comparable analysis of very different, yet internally consistent futures. A detailed presentation of the assumptions and results can be found in the technical report Greenhouse gas emissions under various socio-economic and climate policy scenarios for Switzerland (in German).

Partner, Director
The CCRI focuses on the implementation of a circular economy in European cities and regions. Prognos is supporting the initiative as a project partner in the associated Coordination and Support Office.
Prognos is supporting the North Rhine-Westphalian Ministry of the Environment in organising, implementing and establishing the world's first trade exhibition for the climate adaptation industry.
A single heat day costs the German economy 431 million euros. Our study for the BMAS examines how preventive, climate-change-friendly occupational safety measures can help to limit the damage.
The transport forecast provides the technical basis for Austria’s strategic transport planning. Together with its partners, Prognos is responsible for designing and calculating the baseline forecast, as well as additional supporting scenarios for passenger and freight transport.
Prognos is assessing the potential for decarbonising thermal waste treatment through the use of resource-saving and energy-efficient CO₂ capture and processing technologies.
How effective are the measures proposed by Germany’s federal ministries for the upcoming climate protection programme? Prognos and its partners examined the feasibility of the planned climate protection measures and analysed their impact on the climate.
The network Klimaanpassung&Unternehmen.NRW (NKU) offers exchange, knowledge and market information on climate adaptation in North Rhine-Westphalia. Prognos is leading the network together with partners.
What is the status of the energy transition in Germany? Since 2012, Prognos has been monitoring the energy transition in Bavaria and Germany on behalf of the vbw.
Energy prices remain high, and the expansion of renewable energies continues to fall short of targets: this is shown by our 14th Energy Transition Monitoring report, which we compiled on behalf of the vbw.
On behalf of the BMWE, we evaluate the impact of the BEG in the funding period 2021 – 2025 together with ifeu, ITG, and FIW.
We combine economic research and strategy consulting for sustainable decisions in politics, business and society. Our robust data, precise analyses and scientifically based findings enable fact-based progress – financially independent, politically neutral.
