This would be very useful, but could be difficult as it depends of the manufacturer of the pipe, where and how it is manufactured, how far to site it is transported and what materials it is, to know the Carbon per m. Also depends on the pipe surround material and how/where it was quarried and distance transported to the site to be used as this also effects the Carbon value of the materials. You also need the carbon for excavation depth and one that cant be predicted that would be the disposal of arisings which would be site specific.
