Thanks Christophe. This is helpful, but still requires much manual input from the design team. What seems to be catching steam really quickly is harvesting data from the models and then using EC3 and/or Tally to do the analysis.
These tools are also helpful when designing since they give you immediate feedback on carbon content of materials. This is great when spec'ing materials as it makes it easier to compare building materials based on a number of factors.
It seems this topic came up on the form some time ago (

It would be great if these tools also worked for those of us using Archicad.
