I don’t want to minimize the important of upfront/embodied carbon, because we are all here on this forum discussing it for a reason. But this discussion (and my recent LCAs) really reinforce to me how critical it is to get our energy sources under control, especially if we are approaching this from a total CO2e budget perspective…
And if on-site renewable isn’t an option for a project, then we are left to the mercy of the grid… which is unfortunately outside of our control.
Cue the hopelessness feeling.
