Klimatdeklaration i praktiken : En studie om tillämpning av klimatdeklarationen

Sammanfattning: Sweden has set a goal to be climate neutral by 2045. To be able to reach that goal, theconstruction and real estate sector must go through a change. In 2018 the construction and realestate sector produced one fifth of Sweden´s emissions of greenhouse gases. On the first ofJanuary 2022, a new law will be introduced in Sweden. The new law says that all new buildingsmust have a climate declaration. The Swedish government has hopes that the law will decreasethe emission of greenhouse gases.The purpose of this thesis is to investigate how the challenges that the law brings with it can behandled. Calculations have been made with the purpose to investigate uncertainties and flawswith the data supposed to be used for the calculations in a climate declaration.The study shows that the new law will not force the construction and real estate sector to makeany major changes, since there will not be any limits that regulates climate impact. Results fromthe theoretical study shows that the deviation that occurs when generic data is used instead ofspecific data is bigger than the potential reduction of environmental impact from measures thatreduces climate impact. When more construction products have an environmental productdeclaration and they are being used to a greater extent, the deviations will decrease. Itappeares in the calculations that most of the climate impact occurs during the supply of goodsand product manufacturing. The climate impact from transports is marginal in comparison.
