In this episode, we speak with Matt Kean. The former NSW state politician was once deputy Liberal leader, treasurer, and minister for energy and environment – but he’s now chair of the national Climate Change Authority. That means Kean helps set the Australian agenda in the fight against global warming, shaping federal policies on every hot-button green issue imaginable. Taking on the job was seen in some quarters – by conservative commentators, mostly – as a traitorous move by a “climate communist” now known to some as “Green Kean”. Our new climate change tsar is the subject of a feature profile this week – “Force of Nature” – and hosting this conversation about the powerful enemies Kean now faces, and the fight to save our natural world, is the acting editor of Good Weekend, Greg Callaghan.
