  1. 1. Cost and financing of the sustainability transition of the Swedish road freight transport sector

    Författare :Elmira Parviziomran; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Godstransporter; Hållbar utveckling; Fossila bränslen; Fordon; Kostnader; Finansiering; Batterier; Sustainable development; Electric batteries; Vehicles; Freight and freightage; Fossil fuels; Sustainability transition; Decarbonization; Heavy-duty vehicles; Cost; Financing; Battery; Circular economy; Diesel fuels;

    Sammanfattning : The cost and financing of the road freight sector’s sustainability transition, driven by significant greenhouse gas (GHG) emissions and cost considerations, represent an urgent yet underexplored research focus. This study investigates the costs of fleet replacement with zero-emission powertrains, battery electric vehicles (BEVs) and fuel cell vehicles (FCVs), emphasizing cost variables that have been overlooked in transition research.
