This LCA assumes the impacts from products manufactured in accordance with the standards outlined in this report. This LCA is a “cradle-to-gate” study, and therefore, stages extending beyond the plant gate are not included in this LCA. Excluded stages include transportation of the manufactured material to the construction site; on-site construction processes and components; building (infrastructure) use and maintenance; and “end-of-life” effects.
