Embodied energy of transport - importing building materials

In his book "The Ecology of Building Materials" Bjorn Berge states that the energy consumption in transport of building materials is 0.8-2.2 Mj/ ton km

So in the comparison of Single Ply PVC and TPO being imported into the uk from Switzeraland ---- 800 km distance equates to 1600 Mj/ton= 16,000kwh per ton

This embodied energy is in addition to the embodied energy of manufacture to the "factory gate" so the conclusion of the book “The Ecology Of Building Materials is to purchase local alternative building materials which give the same performance and are affordable.

So… RoofKrete/Krete should make Single Ply PVC and Single Ply TPO, Bitumen and Mastic Asphalt Obsolete because the transport embodied energy of importing Single Ply is the same as the total embodied energy of RoofKrete.
