Embodied emissions of buildings : A forgotten factor in green building certificates
Highlights • The pre-use stage (construction) emissions of buildings occur in a short time. • Wooden buildings seem to emit less compared to concrete ones in pre-use stage according to LCA. • Green building certificates need to consider embodied emissions more exhaustively. The construction and use...
