We’re working to achieve net-zero emissions

Our emission-reduction targets include Scope 1 (fuel), Scope 2 (electricity) and Scope 3 (supply chain) emissions. We were the first Top-20 ASX-listed company to have our 2030 Scope 1, 2 and 3 GHG emission reduction targets validated by the international and independent Science-Based Targets initiative.

Targets adopted by companies to reduce GHG are considered science-based if they line up with what the latest climate science says is necessary to meet the goals of the Paris Agreement. That is, our targets must align with the emissions reductions needed to (at least) limit global warming to well below 2°C above pre-industrial levels, and to aim to limit warming to 1.5°C.

Our 2030 and 2050 targets are:

Towards net zero

  • 50% absolute reduction in Scope 1 and 2 GHG emissions
  • 22% intensity reduction in Scope 3 emissions

Net-zero emissions

  • Reducing all possible GHG emissions associated with our operations
  • Offsetting unavoidable residual emissions to achieve net-zero
Our 2050 GHG targets are now under Science-Based Targets review.

Baseline numbers

All GHG targets are relative to a FY19 baseline. In 2019, our operations generated 122,243 tCO2e Scope 1 and 2 emissions and 503,382 tCO2e Scope 3 emissions.


How we’re tracking

The charts below show how we are tracking in meeting our emissions targets and how we are decarbonising the energy sources we use to power our operations.

Learn how we’re working to reduce emissions

Overall, in FY23 we achieved around 50% reduction in total Scope 1 and 2 GHG emissions compared to the previous year (and 56% below FY19 baseline year). These reductions were achieved through:

  • the NSW Bango windfarm becoming operational in FY23, providing greater coverage for the state
  • shifting to 100% renewable electricity in our North American operations.
  • delivering energy-efficiency projects in all markets (for example, tunnel ventilation optimisation works).
