The number of people that are categorized as being homeless in the Swedish society are increasing. This might be an indication that the methods being used today shows not to be working efficient enough. A group of researchers connected to the University of Lund are now in a process to spread new workingmethods against the problems with homelessness in Sweden. Their goal is to completely erase homelessness as a social problem. This new method of working is distinctively different from the one currently beeing used. The main idea is that a person is to be given a place to live before any other efforts and treatments are being given to them. Because of the differences between the models there is a need of inspiering and committed people with knowledge about issues avolving homeless people and the problems that comes with being homeless. In this essay we have chosen to focus on these inspiering people and what their drive to spread social inventions might evolve in. Often there is a strong case of following the path of the work that has always been used wich is familiar. This often leads to a struggle for the policyentrepreneurs in which they have to persuade the public to try a new solution to the problem. The personal connections an entrepreneur has plays an important part in the process of spreading the word about a new policy. Preservation and a set mind is required of an entrepreneur.

Föreliggande avhandling studerar kommunala policyprocesser i en fråga där ett flertal olika policyområden ingår: övergången till alternativa drivmedel i kollektivtrafiken. Genom att undersöka hur och varför sådana policyer utvecklats i två kommuner bidrar studien dels till att förklara hur policy utvecklas på kommunal nivå; dels till att skapa förståelse för policyskapande där olika policyområden ingår. Genom fallstudier har policyprocesserna vid övergången till biogas i stadsbusstrafiken i Linköpings och Helsingborgs kommuner undersökts. Studien är processorienterad och fokuserar huvudsakligen på hur och varför aktörer, utifrån sina resurser, intressen, problemdefinitioner och lösningar, kan påverka policy. Resultaten visar hur policyprocesserna vid övergången till biogas präglats av traditionella policyområden där aktörer, intressen och resurser skilt sig åt beroende på sektor. Samtidigt visar avhandlingen att en sammankoppling mellan policyområdena för energi, miljö och transport varit väsentligt för att aktörer skulle kunna driva igenom sina förslag. För att göra detta har gränsgångare – policyentreprenörer som gått över gränserna för de tre policyområdena – varit centrala genom att initiera breda samarbeten där aktörer företrädande energi, miljö och kollektivtrafik identifierat och eftersträvat ett gemensamt mål. / This thesis studies municipal policy processes where several policy sectors are involved: the transition to alternative fuels in public transport. Examining how and why those policies have developed in two municipalities, the study will contribute to explain how policy are shaped on a municipal level and also contribute to further knowledge of policy processes where different sectors are involved. Through case studies, the policy processes concerning the introduction of biogas in city buses in the municipalities of Linköping and Helsingborg have been studied. The study is process oriented and mainly focuses on how and why actors with their resources, interests, problem definitions and solutions, can influence policy. The results show that the processes consisted of traditional policy sectors where actors, interests and resources differed between the sectors. In addition, the thesis shows that a connection between the energy, environment and transport policy sectors has been essential for policy development. Boundary walkers – that is, policy entrepreneurs that crossed the boundaries between the three sectors – have been central to initiate broad collaborations where actors representing energy, environment and public transport identified and strived to a common goal.
