Abstract [en]

In this thesis, the greenhouse gas emissions from the extraction of raw material to construction of planned buildings, roads and tramways in Uppsala are studied. The study is part of the work with Roadmap 2050 for a carbon dioxide neutral Uppsala until year 2050 that the Municipality is developing. The goal of the Municipality is to reduce the greenhouse gas emissions to less than 500 kg CO2-eqv per capita and year, compared to in 2011 just over 7 000 kg CO2-eqv per capita and year. The results of this study are compared to this goal.

The study is based on two different possible scenarios of population growth in Uppsala until year 2030 and year 2050. The first one, the base scenario, implies that Stockholm remains the only big centre in the region. The second one, the high scenario, is a network region in which Uppsala has become an equally attractive city. This means that four scenarios have been considered; 2030 base, 2050 base, 2030 high and 2050 high. Another decisive parameter is the composition of material in the different constructions. To calculate the emissions certain LCA:s on roads and buildings, which apply to the situation in Uppsala, has been chosen. For tramways, an approximation had to be made since no LCA could be found.

The result shows that the emissions from the extraction and production phase is more than ten times as big as the emissions from the construction phase of the process. For all scenarios, the emissions from roads are the highest ones in the extraction and production phase while the emissions from trams are the lowest ones. In the construction phase the emissions are highest from apartment buildings for all scenarios except 2050 high, where roads are highest. In the construction phase tramways have the lowest emissions in all scenarios. In total, the emissions of 2030 base is the lowest with 39 kg CO2 per capita and year and the scenario 2050 high is the highest with 120 kg CO2 per capita and year.
