“The embodied energy (carbon) of a building material can be taken as the total primary energy consumed (carbon released) over its life cycle. This would normally include (at least) extraction, manufacturing, and transportation. Ideally, the boundaries would be set from the extraction of raw materials (inc fuels) until the end of the products lifetime (including energy from manufacturing, transport, energy to manufacture capital equipment, heating & lighting of the factory, maintenance, disposal… etc.), known as ‘Cradle–to–Grave’. It has become common practice to specify the embodied energy as ‘Cradle–to–Gate’, which includes all energy (in primary form) until the product leaves the factory gate. The final boundary condition is ‘Cradle–to–Site’, which includes all the energy consumed until the product has reached the point of use (i.e. building site).”
