1. 11. Steering green buses : The opportunities and challenges of introducing renewable fuel in public transport

   Författare :Malin Aldenius; Miljö- och energisystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public transport; Renewable fuel; Electric buses; Sustainable transport; Green public procurement; Environmental requirements;

   Sammanfattning : The aim of this thesis is to compare and analyse the introduction of renewable fuel in the public transport sector, focusing on the challenges and opportunities encountered by involved stakeholders on the regional and local levels. The results contribute to answering three research questions: 1) How do organisational factors and local and regional contextual factors influence the introduction of renewable fuel? 2) What are the challenges and opportunities of using green public procurement as a policy tool to introduce renewable fuel in the public transport sector? 3) How do the challenges and opportunities regarding the introduction of renewable fuel differ depending on the type of renewable fuel? Four papers are included in the thesis. LÄS MER
