Cradle to gate carbon analysis of D5 Green
By Edge Environment*, Sydney 2019
Neocrete commissioned Edge Environment* to conduct a scoping life-cycle assessment (LCA) of the carbon footprint of a range of concrete mixes with and without D5 Green.
The primary intended audience for the LCA is building and infrastructure project teams specifically focused on green ratings such as Green Star and Infrastructure Sustainability Rating.
This LCA shows:
– up to 20% greenhouse gas reduction per cubic meter of ready-mix concrete from cradle to gate from the use of D5 Green;
– and up to 33% greenhouse gas reduction from a combination of cement substitution and the use
of D5 Green.
*Member of Green Building Council Australia, contributes to Green Star’s Technical Advisory Group.
