ABSTRACT: Construction activity is responsible for substantial greenhouse gas (GHG) emissions, but most of these reflect only a single stage of the building construction supply chain. Closing the gap, this work presents a cross-supply-chain perspective on annual material and energy consumption and GHG emissions for the sector on the European scale. These are estimated at the country level, disaggregated for raw material extraction, material manufacturing, demolition, and several intermediary transport stages. The study underscores cement, steel, flat glass, and ceramic bricks as manufactured materials; and sand, limestone, clay, iron ore, and coal as raw materials. Estimates consider both new construction and renovation, across varied typologies of residential and non-residential buildings. The results show that new construction & renovation of the building stock emits 235.31 Mt of CO2 annually, excluding energy consumption for building operations. These are associated with the consumption of circa 1 994.29 Mt raw and construction materials, and circa 1 990.27 PJ of final energy per year. These figures correspond to 4.33% of the total EU values (45 923 PJ). New building construction and renovation account for 63% of the materials used, while the material manufacturing stage accounts for 74% of the final energy consumption. By adopting a full supply chain perspective at the European level, we can support the development of holistic and more targeted public policies to decarbonize the sector.
