Materials, generally, make a up a small portion of the CO2 emissions from construction:

The buildings and construction sector accounted for 36% of final energy use and 39% of energy and process-related carbon dioxide (CO2) emissions in 2018, 11% of which resulted from manufacturing building materials and products such as steel, cement and glass.

The process itself is extremely carbon heavy. My only worry with pre-fab, is that eventually, like all other manufacturing, we'll end up dependent on materials and manufacturing from China. Even the 3rd printed houses, still have a lot of pre-fab parts.
