EN Carbon emission has become a global challenge which requires a global approach before we get to a point of irreversible; the amount of CO2e released to the atmosphere yearly from different construction industries are becoming alarming. To overcome this global climate change (GCC), global warming potential (GWP) caused by CO2eemission, more attention must be placed on the estimation of the carbon footprint of construction materials use in civil engineering construction. The study focuses mainly on carbon footprint analysis and its reduction during extraction of construction materials and construction processes using the Life Cycle Assessment (LCA) and Building Information Modeling (BIM) approach. LCA and BIM approachused to analyze CO2emission from materials extraction (embodied carbon) to construction use stage The paper proposes a simplified method of analysing carbon footprint of construction materials. I.e. concrete, steel and wood. The embodied carbon of the sub-structural and super structural part of the building using existing tools. BIM tool (Revit Autodesk) and One-click LCA Carbon calculation software are used to evaluate carbon footprint in each of the construction phases. A case study of existing building from Sweco Company, Sweden was analysed to calculate the amount of carbon footprint in each of construction stages and materials. The results obtained reveal that the amount of CO2e emission from materials extraction to the site (A1 – A3 in the life cycle assessment) contribute almost 80% to total construction CO2emission, comparison also made between concrete, steel and wood materials.The study identified which of the construction stages contribute immensely to global warming.The study reveals that wood is an environmental friendly material with low carbon footprint compare to concrete and steel.
