Just read these interesting articles regarding embodied energy.

The upshot being that transporation of materials and people is still a much more pressing issue than the energy utilised to create the products in the first place.

I also note the comment at most places in the world timber can have a net negative greenhouse warming impact due to the carbon captured in the growth of the material. Yet for Dubai the associated emissions from transporting timber makes it much less appealing as a sustainable product.

Maybe we need to have supply chain magamenment that tags products with thier carbon emissions in transit.
