Fossil free public transport : Fuel strategy for introduction of electric buses in Uppsala city traffic (English)
Abstract [en]

The Swedish government announced in 2015 that Sweden will work towards becoming "one of the first fossil-free welfare states of the world". The objective is to reduce the usage of fossil fuels by 70 percent by the year 2030 compared with the levels of 2010. Important factors to achieve this is to reduce the amount of transport, increase the use of biofuels and increase the fuel efficiency. The public transport sector plays an important part in reaching these objectives. There is a lot of potential in the biofuel market and in recent years there has been a development in the segment of electric buses in the city traffic. The purpose of the study is to develop a strategy proposal for the use of fossil-free fuels in Uppsala's public transport. The study is delimited to examine the use of fuels in city traffic with a focus on the introduction of electric buses. The report contains an environmental analysis of the advantages and risks associated with the fuels that the public transport administration UL decided to proceed with; biodiesel, biogas, and electricity. Based on the analysis, a strategy proposal was developed for how these fuels can be distributed in city traffic in Uppsala between 2019 - 2029. The study also examines how energy use, carbon dioxide emissions, and traffic pollution are affected if the strategy proposal is implemented. The environmental analysis suggests that biogas will continue to be used in Uppsala's city traffic, together with electric buses. Biodiesel is likely to come to better use in other areas of the transport sector in order for Sweden to reach the target of a fossil-independent fleet of vehicles in 2030. If the strategy proposal is followed the result shows that energy use and emissions of carbon dioxide and traffic pollution will decrease. Energy consumption will be reduced because of the energy efficiency of electric buses. The reduction of traffic pollution is due to the electric buses, but also because vehicles with the Euro V engine has been replaced with vehicles with Euro VI engine, which lowers traffic pollutions.
