6.11.3. Management Practices

As per the DETSI GHG Guidelines, the order of priority for management practices follows the GHG

Abatement Hierarchy, shown in Figure 52.

GHG emissions for the Project cannot be practicably avoided, therefore, management practices focus

on reduction. Proposed management practices to reduce emissions are outlined in Table 56.

Vegetation clearing is the source of 66% of Project emissions due to the

release of captured carbon. Mulching reduces emissions, compared to

traditional methods like burning or bulldozing, by reducing carbon

conversion to carbon dioxide. Mulch can also be utilised in rehabilitation

to promote revegetation and sequestration, particularly in topsoil deficit

areas (da Silva GOA, Dunlop, Nicolson, & Purtill, 2024). Organic matter

that remains stored in the mulch would also lead to increased carbon

content in soil and improve its ability to store carbon.

Optimised material movement will be implemented in line with best

practice guidelines (LarkinSykes Advisory & Brinson and Associates,

2022), to reduce Scope 1 emissions from heavy earth moving

slope of haul roads, and ensuring efficiency in unloading and loading

areas. These measures will maximise equipment usage and reduce

overall runtime, therefore reducing emissions.
