Energy & Decarbonisation

Every tonne of CO2e here carries a price and every abatement option carries a payback, because decarbonisation only gets funded when it competes on the same terms as any other capital project.

How the site filter works

Your site choice is remembered across workspace views.

Profiles and abatement options follow the selected site; totals sum only displayed profiles. Per-site models, emission factors, derived fleet-fuel estimates and the A$35/t carbon-price assumption are unchanged. Intensity comparisons retain the full loaded portfolio benchmark. Showing 1 of 1 modelled sites. Source limits: 500 streams, 500 fleet units, 200 locations, 200 production stages and 20 commodity profiles.

Modelled footprint, not an independently verified (NGER) emissions inventory.

Abatement that pays for itself

74kt of CO2e can be removed on energy-cost grounds alone — worth A$11.5M a year in avoided energy spend for A$110.2M of capital, before any carbon value is counted.
