Abstract [en]

Aviation accounts for approximately five percent of global greenhouse gas emissions through the combustion of fossil fuels. This paper analyses the opportunities and challenges of mitigation measures in limiting travel volume, energy and emission intensity to reduce the climate impact of aviation in Sweden. Several measures are in place that aim to reduce the climate impact of the aviation industry, ranging from regulations to technology alternatives to fossil-based jet fuel. These measures face several crosscutting challenges, many of which are of a socio-economic and political nature, and these aspects are often neglected in favour of focusing on technological solutions. The market creation for alternatives to fossil-based jet fuel is a major challenge, as most consumers today have a limited awareness of and willingness to pay for these innovations. Policy measures in place are proven ineffective in incentivising change. An understanding of the industry as a socio-technical system is required. The value of this review is its broader consideration of the pathways to reduce aviations climate impact, offering new perspectives and pointing to areas for further research considering all components, their interactions and interdependence.

Abstract [en]

Current research on sustainability transitions on aviation heavily favours technological innovation, largely overlooking the crucial socio-political dynamics that govern sustainability transitions. Achieving the aviation industry's ambitious Paris Agreement decarbonization targets requires more than technical solutions. This thesis bridges that gap by examining the role of political discourses within the Multi-Level Perspective (MLP) on the political acceptance of sustainable aviation and its corresponding niche innovations. The focus lies on politicization, polarization and policy implications. In this thesis, frames and narratives are key tools of sensemaking and influence, not only shaping perceptions but also being reshaped by policy actors to align with their objectives. This perspective enhances our understanding of how discourses operate at a deeper cognitive and cultural level, affecting the trajectory of sustainability transitions such as acceptance of particular sustainable niche innovations. This thesis explores how these dynamics influence the development, support, and opposition of niche innovations within the aviation sector. Specifically, it investigates how conflicting narratives can create lock-ins that hinder sustainability transition. This thesis highlights that while discourses can promote niche innovations by enhancing legitimacy and social acceptance, other discourses can obstruct progress by fostering social resistance and diminishing policy support. This dynamic is particularly evident in the Swedish transport sector, where sustainable aviation has encountered both support and resistance, influenced by competing political narratives. Using a comprehensive theoretical framework integrating discourse analysis, MLP and socio-technical transitions, the research examines how sense-making affects sustainable aviation's future, the factors enabling or hindering discursive governance, and how discursive pathways of sustainability transitions evolve with or without policy support. The thesis employs focus groups and semi-structured interviews with stakeholders in the Swedish aviation industry to uncover how niche innovations in sustainable aviation are discursively framed, supported, or opposed. The research findings reveal that politicization and polarization create lock-ins, characterized by polarization between opposing discourses, which are a critical barrier to sustainable aviation. These discursive lock-ins can obstruct policy leadership and limit the emergence of niche innovations, such as drones. The research argues that a nuanced understanding of politicization and polarization is essential for identifying pathways to overcome these barriers and for designing effective policies that support sustainable aviation transitions.

Abstract [sv]

Forskning om hållbarhetsövergångar för flyget fokuserar på teknologisk innovation, men förbiser det avgörande sociopolitiska perspektivet. Att nå flygindustrins hållbarhetsmål kräver mer än enbart tekniska lösningar. Denna avhandling fyller detta forskningsgap genom att undersöka de politiska diskursernas roll inom Multi-Level Perspective (MLP), med fokus på politisk acceptans av hållbart flyg och dess nischinnovationer. Studien fokuserar på politisering, polarisering och policyimplikationer. Ramar och narrativ ses som centrala verktyg för meningsskapande, vilka formar och omformas av policyaktörer för att anpassas till deras mål och därmed påverkar acceptansen av hållbara nischinnovationer. Avhandlingen utforskar hur denna dynamik skapar låsningar som hindrar övergången. Diskurs kan antingen främja nischinnovationer genom ökad legitimitet och social acceptans, eller hindra dem genom att skapa motstånd och minska politiskt stöd. Denna dynamik är särskilt relevant i den svenska transportsektorn, där hållbart flyg har mött konkurrerande politiska narrativ. Med hjälp av ett ramverk som integrerar diskursanalys, MLP och socio-tekniska övergångar, undersöker denna avhandling hur meningsskapande påverkar hållbart flyg. Avhandlingen använder fokusgrupper och semi-strukturerade intervjuer med intressenter i den svenska flygindustrin för att analysera hur nischinnovationer diskursivt inramas. Resultaten visar att politisering och polarisering skapar kritiska, diskursiva låsningar som är ett betydande hinder för framtiden för hållbart flyg. Dessa låsningar hindrar politiskt ledarskap och begränsar framväxten av nischinnovationer (t.ex. drönare). Forskningen argumenterar att en nyanserad förståelse för politisering och polarisering är avgörande för att identifiera vägar för att övervinna dessa barriärer och för att utforma effektiva policyer som stöder övergången.
