I’m curious to know if anyone has encountered an embodied carbon data set that isolates GWP related to existing building demolition, either with LCA Module C1 in isolation, or C1 through C4 grouped together. Looking at the 2017 CLF Benchmark Study, it doesn’t appear that demolition emissions are quantified, and the RICS database does generate reports that provide columns for Module C, though it doesn’t appear to be reported for most of the LCAs there.
