I only skimmed this thread after the first post, but if I’m following correctly, then I can add some further input:
We regularly see full LCAs, where the grid decarbonisation is considered in line with the conservative version of the latest UK Future Energy Scenario decarbonisation pathway; and the conclusion is consistently showing embodied as significantly larger than operational impact over a 60 year reference study.
My experience may be biased though, as we’re doing studies on buildings with ambitious EUI targets, driven by planning requirements and sustainability accreditation (e.g. NABERS).
