This study compares the climate impact of various fuel types during the life cycle of a passenger vehicle in the current Swedish market. The goal of this study is to indicate quantitatively how selected fuel types in the current Swedish market compare with each other in terms of greenhouse gas (GHG) emissions, accounting all stages in the vehicle and fuel life cycle, i.e. production of vehicles, use phase of 200 000 km and the vehicle end-of-life. In addition to conventional fuels and electricity, biofuels and hydrogen are included in this study. The emphasis has been to use only one main source per life cycle phase, thus minimizing the inconsistency in the underlying assumptions. However, as data available for the purposes of this analysis are limited, some unavoidable variation between the assumptions of the studies exists. The evaluation is limited to publicly available reports, thus the full transparency on the background data used was not possible.

Rapport jämför klimatpåverkan från olika bränslen över ett passagerarfordons hela livscykel. De bränslen som ingick i studien valdes på grundval av att de är de vanligast förekommande bränslena på den svenska marknaden. Öppet tillgängliga källor har legat till grund för det modellerade resultatet.3 Bristande tillgång till data ledde därmed till att källor med heterogena antaganden och avgränsningar inkluderades. De resultat som presenteras bör därmed tolkas som indikativa.
