Abstract
Problem:
• How much climate impact dose a general concrete bridge have today? • Which is the lowest climate impact you can reach with today’s best options? • Is it possible to build a climate neutral concrete bridge 2050? Purpose: Today climate change is a important and debated subject. The purpose of this master thesis is to compare today's emissions to what might be possible in the future. The essay purpose is also to investigate in what way choosing different materials and suppliers effects carbon emissions from the reference project. Method: Initially the work started with studying relevant literature and empiricism, the purpose was to get a deeper understanding of the subject. Qualitative interviews were conducted with some of the... (More)
Problem:
• How much climate impact dose a general concrete bridge have today? • Which is the lowest climate impact you can reach with today’s best options? • Is it possible to build a climate neutral concrete bridge 2050? Purpose: Today climate change is a important and debated subject. The purpose of this master thesis is to compare today's emissions to what might be possible in the future. The essay purpose is also to investigate in what way choosing different materials and suppliers effects carbon emissions from the reference project. Method: Initially the work started with studying relevant literature and empiricism, the purpose was to get a deeper understanding of the subject. Qualitative interviews were conducted with some of the reference project suppliers. Results: In general, a concrete bridge like in your reference project is the source of 780 t carbon dioxide equivalents. In this essay only 675 of those are included. When products and suppliers with the least carbon dioxide emissions today are used, the same number is 433 t carbon dioxide equivalents. Conclusion: One of the conclusions that were made from this essay is that the construction business has started the journey to become climate neutral in 2050. Several big actors have already committed to this goal, but for the goal to be possible everyone must be on board. Since some significant actors already started their journey, it should be easier for the small ones to follow. Another conclusion from this essay is that it’s likely possible to
build most parts of the reference project with zero climate impact in 2050. Reaching zero seems to be the hardest for the rebar, therefore it should be of interest to have a continued dialogue with the suppliers. That will help keeping track of how the rebar emissions develop. To sum everything up, it seems possible to build a concrete bridge in 2050 with zero climate impact. With the materials and techniques we have today it's not possible, therefore it will demand continued development and research in the area. (Less)
