Brisbane Airport is now 100 per cent powered by renewable electricity, having achieved net zero on two of the three metrics – scope one and scope two – used to measure emissions.
Scope one emissions are from sources of which an organisation either owns or has direct control, while scope two refers to emissions from the energy consumed by the organisation.
Emissions from departing and arriving aircraft were considered scope three, so did not factor into the airport’s achievement.

That caveat was not lost on Brisbane Airport Corporation chief executive Gert-Jan de Graaff.
“There is far more work to be done,” he said.
“We know the most significant source of emissions comes from aviation fuel used by our airline partners.
“It’s why we continue to represent all airports on the Australian Jet Zero Council, and support research undertaken at Brisbane Airport by Stralis, which is developing a hydrogen-electric aircraft, with a test flight planned for this year.”
As of New Year’s Day, all the airport’s electricity was sourced from onsite solar panels (10MW) and renewable generation from Stanwell Corporation via the power grid.
“From midnight our renewable power purchase agreement kicked in with Stanwell, providing up to 185 GWh of renewable backed wind and solar energy per year from regional Queensland. This is a milestone moment,” de Graaf said.
