The continuing growth in passenger transport and the associated increase in CO 2 emissions remain major challenges for our society. Shifting passenger transport to more sustainable modes of transportation contributes to addressing this challenge. Multimodal transportation hubs (MMTHs) coordinate and integrate different modes of transportation by improving transfers between them. In addition, MMTHs offer a high quality of stay with a wide range of services, as well as a compact, mixed-use urban development with a high density of uses around them. The transformation of railway stations and their environments into MMTHs is addressed in discussions of transit-oriented development (TOD) and the concept of "node and place." However, there is a lack of a systemic approach that structures the problem involving the different worldviews of the actors. In addition, the necessary changes and measures are largely unknown. Based on the soft systems methodology (SSM), we conducted 20 SSM interviews and two SSM workshops (n = 10 each). Our results show that the problem can be structured into the three layers of "national long-term integrated optimization of the passenger transport sector and spatial development," "local short-to medium-term planning and implementation," and a "regional, bidirectional transfer by policy-making and planning." The transfer layer between the national, long-term and local, short-term worldviews is key and must be strengthened. Furthermore, we present systemically desirable and culturally feasible measures for each layer to improve the current situation of the transformation—a national MMTH program, creating an overarching vision, a caretaker for local implementation to coordinate the interests of actors, and collaborative development of regional master plans and an explorative approach to ensure bidirectional exchanges between the national and local layers. Although the structuring of the problem and the measures were developed from a Swiss viewpoint, we expect that the results will also be useful for other decentralized states. • Structures the problem of transforming railway stations and their surroundings into multimodal transportation hubs (MMTHs). • Help actors responsible or affected to perceive different worldviews and develop a common understanding. • Present systemically desirable and culturally feasible measures to improve the current situation of the transformation. • A regional "bidirectional transfer layer" between the local, and the national worldviews needs to be strengthened.

Carbon dioxide removal (CDR) is recognized as an important tool for addressing residual emissions and achieving net-zero emission targets. While some have cautioned that a focus on CDR in policy processes may lead to delayed efforts to mitigate emissions, others have argued that such concerns are unwarranted. Nevertheless, the circumstances under which CDR could help or delay emissions mitigation in given contexts remain unclear. This paper explores the emerging discourse on CDR in Switzerland. We examined how the CDR community legitimizes CDR and limits its scope, and what the implications are for emissions mitigation. Switzerland is home to growing businesses in CDR and has pioneered the implementation of international offsetting projects under Article 6.2 of the Paris Agreement. We found that numerous promises help legitimize and attract interest in CDR. Actors use discursive strategies and rules to limit CDR and avoid disappointment in its contribution to climate mitigation. The idea that emission reduction should prevail over removal is promoted accordingly, which ironically helps legitimize the CDR idea yet dodges the question of how much removal is possible and for balancing which emissions. Superficial engagement with the issue is reinforced by the normalization of inflated promises and the sentiment that the mitigation deterrence rhetoric erodes trust in CDR. We argue that this can contribute to mitigation delays by evading the debate on what it is possible to remove and taking resources from alternative measures. We recommend a thorough discussion to examine the risks and the implementation of rules that minimize them. • Mitigation deterrence discourse leads to efforts to avoid substitution dynamics. • "Reductions first" legitimizes CDR without coordinating emission residuals. • Inflated promises of CDR may reduce resources for more realistic measures. • Attention to CDR dynamics is required to help achieve comprehensive decarbonization.

To combat climate change, carbon emissions from everyday mobility must be lowered. This can be achieved by improving vehicle efficiency, shifting to low-carbon modes of transport and avoiding travel. Most of the literature focuses on shifting mobility away from cars, mainly in the context of commuting. However, mobility is embedded deeply in everyday life and is much more complex. This research tries to broaden the scope and not only analyse the mode of transport that people choose but also the purposes that their mobility serves and how this influences their modal choice. Contrary to the dominant literature's emphasis on urban mobility, this study focuses on rural mobility, highlighting its specific challenges. As a case study, the mobility practices of residents of the UNESCO Biosphere Reserve Entlebuch (UBE) in Switzerland were investigated. Using a social practice approach has proven useful in analysing how individuals shape their everyday mobility. The study 'zooms in' on how practices are configured and 'zooms out' on the connection between mobility practices and mobility purposes, with the overarching aim to explore the key characteristics and dynamics of rural everyday transport in Switzerland, using the UBE as a case study. Semi-structured interviews were conducted and analysed adopting a thematic analysis approach. The results indicate that in the rural context geographical conditions and infrastructure availability exert more influence on how practices are performed than in urban contexts. Also, the time spent on mobility was valued differently depending on the mobility purpose, leading to different modal choices for different mobility purposes. Finally, the results demonstrate that strong social capital within a community can foster low-carbon mobility in three ways: shorter distances travelled for shopping and leisure purposes; a preference for active modes of transport; and self-organised collective transport. These findings highlight the importance of considering mobility practices' embeddedness in everyday life while identifying potentials for shifting to low-carbon modes of transport, as well as avoiding travel in the first place. • Rural mobility was investigated using a social practice approach. • Aside from commuting, mobility related to shopping and leisure was analysed. • Justifications for mobility practices vary depending on the mobility purpose. • The relativity of space and time is often used to justify high-carbon mobility. • Strong social capital can foster low-carbon mobility.

Geothermal energy is an essential component for the successful decarbonization of the global energy supply. Its success will depend both on technological progress and on public reaction to this technology. The goal of this study is to analyze how deep geothermal energy has been discussed in the mass media in Switzerland, with an emphasis on the actors, as well as on the arguments and frames they use. We analyze media articles published from 1997 to 2013 in two major Swiss newspapers. In addition to scrutinizing arguments in favor of or against deep geothermal energy, we cluster them around four major frames–energy transition, risks, technology, and costs–with the first and second being the most prevalent. We compare which actors promote which frames and show that industry predominantly focuses on the technology's potential for energy transition, while science presents information about risks. We discuss how these frames might impede the future development of deep geothermal energy and conclude by stressing the importance of transparency and public engagement in the siting process of future geothermal projects.

Abstract: Many researchers and policy makers argue for a radical change in the current energy system. This paper presents a transdisciplinary case study of a rural, developing Swiss community in which a number of alternative, ambitious goals for the energy system were developed and critically reviewed by both academics and practitioners, such as energy consumers, energy industry representatives, and experts. The study shows that in the beginning the community was not ready to discuss energy issues on a detailed and ambitious level; a focus on local community development was more promising a beginning than global goals, such as climate change mitigation. Moreover, there is a need to open up to many different visions and be more explicit about the concrete energy measures needed and their potential consequences. Some visions need stricter planning and are, thus, less robust with respect to implementation and consensus. Finally, we argue that moderate, flexible energy goals will likely meet less resistance in implementation. We claim that similar results can be expected elsewhere and, thus, more general lessons can be learned from this case study. [Copyright &y& Elsevier]

Abstract: The redevelopment of railway stations calls for the integration of many different objectives. Two crucial challenges thereby are the development of a common system understanding among the multiple stakeholders with potentially conflicting interests and the structured definition of comprehensive assessment criteria. Defining the functions of the system railway station, i.e. discussing what the system should do, can support solving these challenges. Based on a review of Swiss railway stations in a transdisciplinary research project applying four focus groups (n=38), 28 expert interviews and two expert workshops, we present a structured framework of five generic functions of railway stations and their interdependencies. The five generic functions are: linking catchment area and transport network, supporting transfer between modes of transport, facilitating commercial use of real estate, providing public space, and contributing to the identity of the surrounding area. Potential conflicts between functions are identified. They concern the competition of multiple functions for space, for customer attention or for revenues as well as increasing system complexities with station size. We illustrate how the framework of functions can be used to foster a common system understanding and to develop assessment criteria. Although elaborated from a Swiss perspective the framework is perceived adaptable to railway stations of other countries. [Copyright &y& Elsevier]
