Australian growth projects greenhouse gas emissions

We are committed to being part of the solution as the world transitions to a lower-carbon economy.

Our Australian growth projects will deliver a cleaner energy source to meet growing energy demand.

Woodside supports and shares the aspiration for net-zero emissions by 2050, implicit in the Paris Agreement.

Achieving this is a global challenge - providing safe, clean, affordable and reliable energy while reducing emissions.

Scientists from the UN’s Intergovernmental Panel on Climate Change (IPCC) and the International Energy Agency (IEA) have shown that substituting gas for higher-emissions fuels is helping avoid emissions. The IEA models a Sustainable Development Scenario that achieves the less-than-two-degrees objective of the Paris Agreement. In this scenario, gas use for electricity generation doubles in our customer nations.

The IEA's modelling shows the offshore gas fields we are proposing to develop have a significant role to play in a lower-carbon world.

How much will the Australian growth projects emit?

Greenhouse gas (GHG) emissions associated with our Australian growth projects include:

  • Scope 1 - direct emissions from the production of LNG and other hydrocarbon products (e.g. condensate).
  • Scope 2 - indirect emissions from the consumption of electricity.
  • Scope 3 - indirect emissions from activities like transport and end-customer use of products.

Greenhouse gas estimations for each project are available in the relevant environmental assessment documentation.

As part of Commonwealth and Western Australian state assessments, we will have a limit on project emissions set by regulators, and we will be required to operate within that limit.

Forecast Scope 1 and 2 emissions from current and future project assets1 are estimated to be 15.9 million tonnes per annum (MTPA) CO2-e, increasing from the current 9.6 MTPA for the NWS Project and Pluto LNG. This increase is driven by:

  • The approved second train onshore at Pluto LNG; and
  • New sources of offshore emissions at Browse and Scarborough.

 

1Scope 1 and 2 total emissions are based on the average annual emissions from proposed new Browse and Scarborough offshore facilities and the maximum approved onshore emissions associated with Pluto and KGP operating as tolling facilities. Existing emissions from NWS offshore assets will decline over time and are therefore not estimated in the future state. Emissions from other resource operators supplying hydrocarbon feed to the onshore tolling facilities are not included as they will be subject to their own approval processes.

Scope 3 emissions will increase by 16 MTPA, again due to the approved second train onshore at Pluto LNG:

  • Approximately 65% of Scope 3 emissions associated with LNG exports are described in the NWS Extension approval currently under public environmental assessment. The NWS will not increase its annual emissions - the proposal is simply to operate for longer.
  • The remaining 35% of Scope 3 emissions from LNG exports were described in the Public Environmental Review/Report for the Pluto LNG Development State and Commonwealth approvals during 2006-08.
