# Circular Economy 5.1A Embodied carbon assessment / lifecycle assessment
# Applies to
Large (60-249 lots) and very large (250+ lots) subdivisions
# Objective
To reduce the upfront carbon emissions associated with subdivision infrastructure.
# Summary
Excellence is awarded where an upfront carbon or lifecycle assessment is used to identify and demonstrate lower carbon material and construction choices across methodology, asphalt, concrete, aggregates, bedding sands, and pipe/conduit.
A minimum 10% reduction in embodied carbon compared to Business As Usual must be achieved.
Examples include minimising earthworks, using recycled content in asphalt and concrete, reducing water use, and selecting pipes laid on recycled glass sand or made from recycled PVC or HDPE.
