Road To Net Zero

Presented by Powerhouse

It’s official: the vast majority of Australians want us to lead the world’s climate change solutions and most support a national target for net zero greenhouse gas emissions, according to the Australia Institute’s Climate of the Nation 2020 report. But what does net zero look like and how do we get there?

In a panel discussion presented by Powerhouse Museum at the 2021 Sydney Science Festival, leading Australian scientists and policy experts will outline a road map for achieving carbon neutrality across agriculture, energy, industry and transport over the next decade. Moderated by festival programmer Catherine Polcz, the panel will also highlight the opportunities for economic growth and innovation through the transition to net zero.


Rowan Foley is the founder and chief executive of the Aboriginal Carbon Foundation, a non-profit organisation that connects Aboriginal communities supplying carbon credits with councils and businesses seeking to offset their carbon pollution. The foundation trains Indigenous rangers who lead the projects, deploying cultural burns and other traditional land management techniques to earn carbon credits. Foley comes from the Wondunna clan of the Badtjala people – Traditional Owners of Fraser Island.
