Concrete evidence of our commitment to innovation in sustainability

Concrete is typically a major contributor to the embodied greenhouse gas emissions of an infrastructure asset and 22,625 tonnes of pre-cast carbon neutral concrete culverts were installed on new rail track and road connections on the 107km Parkes to Narromine section in NSW between March 2019 and March 2020.

The carbon neutral culverts on the Parkes to Narromine project alone will reduce carbon emissions by over 7,250 tonnes, which is the equivalent of removing about 1,350 vehicles off the road for a year.

The culverts, which are manufactured by Humes, a division of concrete materials supplier Holcim Australia, reduce carbon emissions using supplementary cementitious material with remaining emissions neutralised via certified carbon offsets.
