The performance of natural stone as a sustainable building material is appraised in terms of the embodied energy (EE) and specifically embodied carbon (EC) impact of the initial build. This impact is appraised alongside the operational efficiency expected of the structure, and the whole-life impact of building with stone is also discussed.

The conventional materials replaced by recycled materials were crushed stone (67%), sand (50%), and asphalt cement (70%). The results revealed GHG reductions of 16 to 23% [13]. In Australia, a GHG reduction of about 10% was determined when geopolymers replaced ordinary portland concrete (OPC) in the manufacture of concrete [14].
