• Driver efficiency training scheme to reduce emissions from truck movements
Recycling and reuse
• Construction and demolition at KRD – 88% diversion, 2.5% of this is reused
Construction energy
• Using hybrid and 100% electric plant on site underground – reduces plant emissions by 80%
Water use
• 3% of the water we use on the project is recycled

Materials reduction - Concrete

Concrete makes up ~ 2/3 of the material's embodied carbon emissions, mainly due to its cement content. By replacing it with fly-ash*, the concrete’s footprint to date has been reduced by 8,466 tCO2e = 18%. Concrete 60% Structural Steel 7% Reinforcing Steel 29% Cement 4% Materials footprint breakdown -18%10,000 20,000 30,000 40,000 50,000 60,000 Total tCO 2 e Concrete footprint comparison Concrete footprint without fly-ash Concrete footprint with fly-ash *Fly ash is a by product from coal fired power plants

A total saving equivalent to
