I find that because embodied carbon intensity varies significantly based on building height and use that yes, the target can be easy to achieve for some types of buildings, but challenging for others!
I also like the LETI embodied carbon target alignment as a reference point: https://www.leti.london/_files/ugd/252d09_a45059c2d71043cdbcffc539f942e602.pdf
It has specific A1-A5 targets (matches ILFI’s Zero Carbon scope), whereas the CLF data includes a variety of scopes.
