Cradle
Embodied Carbon, The Inventory of Carbon and Energy (ICE), By Prof. Geoffrey Hammond and Craig Jones, Ed. Fiona Lowrie and Peter Tse, published by BSRIA in 2011, defines the cradle as: ‘…the earth, i.e. material deposits within the ground.’
It suggests cradle-to-gate: ‘Encompasses all input and output flows (as applicable from the system boundaries) between the confines of the cradle up to the factory gate of the final processing operation.
It defines cradle-to-gate + end-of-life as: ‘Cradle-to-gate plus the end of life processes. This excludes the use phase.’
Cradle-to-grave as: ‘Cradle-to-gate plus operation plus end of life processes. A complete study.’
And cradle-to-site as: ‘Cradle-to-gate plus delivery to the site of use (installation site).’

[edit] About CIRCuIT
The Circular Economy wiki is supported by the Circular Construction in Regenerative Cities (CIRCuIT) project, which is funded by the European Union's Horizon 2020 research and innovation programme. CIRCuIT is a collaborative project involving 31 ambitious partners across the entire built environment chain in Copenhagen, Hamburg, Helsinki Region and Greater London. Through a series of demonstrations, case studies, events and dissemination activities, the project will showcase how circular construction practices can be scaled and replicated across Europe to enable sustainable building in cities and the transition to a circular economy on a wider scale.
