    Die Wärmewende in Haushalten ist ein wichtiges Ziel der Bundesregierung zur Erreichung der Klimaziele. Im Jahr 2023 wurden Wärmepumpen als Alternative zu einer fossilen Wärmeversorgung teilweise kontrovers diskutiert. Die Stimmungslage in der Bevölkerung zeigt, dass die Akzeptanz von Wärmepumpen in Deutschland insgesamt positiv und zwischen 2022 und 2023 stabil war, die Kaufbereitschaft jedoch leicht abnahm. H2-Ready-Gasheizungen als neue Technologie erfahren ebenfalls Zustimmung – auch wenn hierzu bisher kaum Wissen vorhanden ist.

    Regional eco-innovation trajectories
    ( 2024)

    Losacker, Sebastian
    Given that eco-innovations and the associated renewal of regional economic structures are pivotal in addressing environmental challenges, regional research is increasingly focusing on their spatio-temporal dynamics. While green technological and industrial path developments in specific regions have received considerable attention, little effort has been made to derive general patterns of environmental inventive activities across regions. Drawing on unique data capturing both green incumbent and green start-up activities in the 401 German NUTS-3 regions over the period 1997-2018, this paper sheds light on how eco-innovation activities unfold in different regional contexts. For this purpose, we introduce sequence analysis methods into the research toolkit of research on regional development. These novel methods allow us to understand to what extent regions engage in eco-innovation activities, how these activities change over time and to what extent similar or unique eco-innovation trajectories (co)evolve. Based on this empirical approach, we distinguish different types of regional eco-innovation trajectories and find a strong persistence and path dependency in green regional development.

    In response to growing concerns about the environmental impact of the shipping industry, this study examines the potential impacts of retrofitting on the shipping industry and the barriers and incentives that may affect the adoption of low-emission technologies. The MATISSE-SHIP agentbased model of transitions is extended to include retrofits. The results suggest that retrofitting can lead to a rapid decline in the use of high-sulphur fuel oil, with wind-assisted technology emerging as a competitive and cost-effective option for shipowners. Additionally, retrofitting can accelerate the transition to a diverse and low-carbon portfolio of propulsion technologies. The findings indicate that the success of decarbonization efforts in the shipping industry depends on a range of factors, including reliable supply that affects the accessibility and affordability of alternative fuels. Policymakers should consider these factors when developing policies and incentives to encourage the adoption of low-emission technologies in the shipping industry.

    Can University Leaders Effectively Promote Research on Complex Societal Challenges? A Change-Agency Perspective
    ( 2024)
    Kroll, Henning orcid-logo
    ;
    Schubert, Torben orcid-logo
    In recent years, new expectations have been placed on universities, demanding academic contributions towards solving large-scale, interdisciplinary challenges. This is in conflict with existing insights from university governance research, which emphasises that scientific communities focus on reproducing disciplinary practices that are unsuitable in addressing societal challenges, because the problems associated with them are usually large-scale, complex and interdisciplinary. In light of this seeming paradox, we revisit the question of how- and on which theoretical grounds - universities may still be able to develop suitable internal governance mechanisms that allow them to address complex societal challenges effectively. Because university leaders are usually unable to coerce individual researchers to address such challenges in their research simply through their bureaucratic powers, we will argue that university leaders can, however, leverage individual researchers' agency to deviate from routine and disciplinary practice by developing novel or legitimising existing interdisciplinary scripts necessary to deal with such societal problems. Specifically, we outline that university managements can create a dual role consisting of the communication of legitimising interdisciplinary research on societal challenges, as well as providing for the necessary degree of interdisciplinary coordination by convening researchers around these topics.

    Das Deutschlandticket ermöglicht seit Mai 2023 bundesweit Zugang zum ÖPNV zu einem monatlichen Preis von 49 €. Aktuell wird es von ca. 10 Millionen Menschen genutzt. In diesem Beitrag zeigen wir auf Basis von Daten einer halbjährlich stattfindenden Befragung, dass der Besitz bzw. die Kaufabsicht des Deutschlandtickets mit einer erhöhten Nutzung des ÖPNV und einer positiveren Einstellung gegenüber dem ÖPNV zusammenhängt. Auch subjektive Mobilitätsbedürfnisse werden durch das Deutschlandticket stärker erfüllt.

    To transition towards sustainable mobility in emerging economies, fostering the use of electric vehicles (EVs) is required. This necessitates the development of an efficient management system for end-of-life (EoL) EV batteries under a circular economy principle. Using Thailand as a case study, this paper provides a holistic analysis by developing a Cost-Benefit Analysis (CBA) and deriving policy implications from the CBA results that consider stakeholder perspectives at the micro level and the uncertainties of future development. The findings suggest that the economies of scale (plant centralization) and the share of cathode chemistries play pivotal roles. In some cases, investment incentives may be required depending on the inflow of EoL batteries, technological advancements, and market volatility. A policy mix combining EoL volume-focused (i.e., enhancing battery collection rates/imports and establishing a clear policy roadmap for scaling up recycling operations) and monetary measures (i.e., taxes and financial subsidies) is essential to establish recycling facilities.

    Current and future roles of the automotive and ICT sectoral systems in autonomous driving - Using the innovation system approach to assess value chain transformation
    ( 2024)
    Grimm, Anna orcid-logo
    ;
    Walz, Rainer orcid-logo
    In this paper, we assess the current and future roles of the automotive and the information and communication technology (ICT) sectoral systems in the provision of autonomous driving and draw conclusions on the potential configuration of the corresponding value chains. We approach the question of value chain transformation from an innovation system perspective, combining sectoral, national and technological perspectives on innovation systems. We introduce a supplementary function at the intersection of the sectoral and technological innovation systems that describes the interactions between the automotive and the ICT system. By choosing indicators that allow for the sectoral and national differentiation of activities, we are able to identify differences and similarities in engagement between the automotive and ICT sectors and countries. Furthermore, we find various and changing types of interactions and relationships, such as competition, cooperation or spill-over, between the sectoral systems. Our findings underline the relevance of contextual factors to the dynamics and design of innovation systems, based on which we propose an approach for integrating different perspectives into one study. We find the strength of the innovation system perspective in its structuring and holistic characteristics and demonstrate its applicability to the assessment of value chain transformation.

    Commentary: transitions research and sustainable tourism
    ( 2024)
    Köhler, Jonathan orcid-logo
    This commentary discusses the growing connections between sustainable tourism research and the sustainability transitions literature. The common ground between sustainability transitions and sustainable tourism starts from the problem definition of unsustainability in tourism and the consequent need for system change. Research into sustainable tourism engages with several areas discussed in the recent sustainability transitions research agenda. These include: understanding radical innovation for sustainability that involves (socio-technical) system level change; the politics and power struggles in transitions processes; organisational and industrial aspects of sustainability transitions; the geography of transitions; and ethical/just transitions. The papers in this special issue also show that evolutionary economic geography (EEG) views on sustainability transitions in tourism are in line with the concepts of innovation and change in the multi-level perspective on sustainability transitions (MLP). This should enable a fruitful interaction between the two fields of sustinability transitions and sustainable touism.
