Uppsala municipality´s goal is to reduce the CO2 emissions by 2050 to an amount of 0.5 ton CO2 per capita per year. This value is a combination of different parts e.g. electricity consumption, isolation of houses and transportation. The transport sector is one of the largest polluters when it comes to CO2 emissions in Uppsala. Therefore the aim of this thesis is to find out, with the help of two future scenarios in the transport field, how it is possible to minimize emissions and come closer to reaching Uppsala’s goal. The two future scenarios were constructed for the transportation sector. They give possible ideas about how to reach a part of that goal. The first scenario suggests taking away all cars in a specially defined environmental zone and expanding public transport so that most of the inhabitants in the city do not need to use a car. Public transport including buses and taxis will be driven with alternative drive systems such as biogas or electricity. Goods transport will be carried out using electrical overhead lines. The information and data used were collected with the help of Uppsala’s municipality, UL, Trafikverket, IVL. The computer simulation program LEAP was fed with the assumptions stemming from these data. This was done in time periods of 10 years, 2013-2020, 2020-2030, 2030-2040 and 2040-2050. In the second scenario, the cars in Uppsala are not be banished, but their engine types will be changed to hybrid, electrical or bioenergy driven ones. The local traffic expansion as well as the use of bionergy discussed in the thesis will also happen in 10 year periods. Whichever scenario is adopted the thesis demonstrates that it is possible to drastically reduce and minimize the quantity of emissions.
