Chris De Cuyper, managing director of Fremantle Seaweed, joins us to unpack asparagopsis, the red seaweed CSIRO discovered almost by accident, and the six-year journey to actually grow it at scale off the WA coast.

Hudson Worsley, Chair of MECLA (the Materials and Embodied Carbon Leaders' Alliance) joins us to unpack embodied carbon in construction.

And how in Australia, construction sits at the centre of the net zero transition that almost no one is talking about.

Hudson helped set up MECLA five years ago with WWF-Australia. It now brings togethe...
