Mapping material use and embodied carbon in UK construction Open
The latest available high-level top-down analysis shows that the embodied carbon of the UK construction in 2018 was 43 MtCO2e, of which 80% came from materials and on-site activities. In this paper, for the first time, we combine a detaile…
