Results Summary

Results are used for internal concept design at this stage. In order to measure, reduce and report on carbon emissions, materials efficiency and wider embedded environmental impacts, HS2 have adopted a life cycle assessment (LCA) approach. This modelling will include impact analysis across all life cycle stages from the extraction of raw materials through to processing, transport, use and disposal.  Using eToolLCD, the modelling will be conducted in accordance with applicable standards including BS EN ISO 14040, BS EN ISO 14044, BS EN 159783 and PAS 2080. The LCA modelling results will also be used to demonstrate achievement of credits within BREEAM Infrastructure.

This assessment will be conducted internally at HS2 and certified by eTool.
