We did not build our cities with sustainability in mind. Can technology transform them into smart tech cities for tomorrow?

This panel discussion will highlight the role climate technologies have in transforming our cities. What will power and connect us in the future? What is really going to work and what needs to be debunked so we focus on the vision and future while we transform Australia into a sustainable technology driven economy.

After a 15-year career in building startup and impact ecosystems, leading a VC fund and influencing multi-sectoral collaborations, Grace Sai, Co-Founder and CEO of Unravel Carbon is determined to bring all that together to solve climate change.

In a panel discussion led by Michael Bromley, Grace and climate tech entrepreneurs will have us envision the smart tech cities of tomorrow.
