TRACK CHANGES - chats with climate change and sustainability experts

What is heavy industry doing to cut emissions? What more can it do?

We've got some real heavyweights talking about cutting CO2 and methane emissions from heavy industry - Margi Johnson (Australian Aluminium Council), Ben McGarry (Aurecon), and Trent Hawkins (ERM). They're a very talented crew, each with hands-on experience, and each with a deep knowledge of 'big picture' factors that influence business decision-making on cutting emissions that cause climate change. And they cover some fascinating ground - sometimes agreeing and sometimes disagreeing. What are big emitters doing to decarbonise, and what needs to happen for them to do more? What should emerge from the Safeguard review (Australia's main policy for cutting emissions from heavy industry)? Tune in to find out!

State and territory climate and sustainability developments in 2026

An update on what to expect from Australian states and territories on the climate change, sustainability, and waste management front in 2026. Which state has an approach to climate change and sustainability that would make great fodder for a standalone true crime podcast? Which one has an approach that would make for a great wellness podcast?  Which state isn't reviewing its framework environment law, even through its Auditor-General has said it is necessary? How many coordinator-generals does it take to decarbonise an economy? And where did hosts Dr Franziska Curran and Murray Griffin respectively spend their holidays? You'll hear a reference in this episode to the novel 'I want everything' by Dominic Rivera. Check it out!  And you'll also hear a reference to the 1960s pop song 'Una Lacrima Sul Viso', by 1960s Italian hearthrob crooner Bobby Solo. Check out the video version on YouTube! Enjoy!  

Net zero or real zero? Which climate pollution target is best? An open mic episode!

Net zero or real zero? This 'open mic' episode features short audio clips from a range of people, giving their views. Then podcast hosts Dr Franziska Curran and Murray Griffin weigh in with their views. Is one concept a misguided fantasy, and the other our best hope? Or are both concepts useful? Tune in to find out!  If you like this episode, don't forget to rate it on your favourite pod platform and share it with friends/colleagues! 

What we got from the COP30 climate summit, what we need from COP31

Featuring a chat with Carbon Pulse North America editor Allison Gacad, and Carbon Pulse Asia Pacific editor Mark Tilly. Allison and Mark discuss the highs and lows of the COP30 climate summit in Brazil, and chat about what they'd like to see from the Turkiye-Australia-Pacific COP31. Can next year's TAPCOP stare down the fossil fuel interests that managed to keep a fossil phasedown out of the COP30 formal outcomes document?  Allison also talks about the billions of dollars raised for the Tropical Forests Forever Facility, and Mark chats about one of the best acronyms to come out of the UNFCCC in quite a while - BAM - the Belem Action Mechanism. Enjoy!

The world's newest (and prize-winning) environmental treaty - protecting our high seas

The world's newest environmental treaty will protect the high seas - those parts of the ocean that belong to no nation. These marine waters extend over about half the planet. This ambitious treaty recently won the world's most prestigious environmental prize - the Earthshot prize for reviving our oceans. The prize was accepted on behalf of the treaty by the director of the High Seas Alliance - Rebecca Hubbard.  In this episode, Track Changes hosts Franziska and Murray do a virtual 'trip' to Rio to recreate that well-deserved prize-winning moment at the 2025 Earthshot prizes. And then we chat with Rebecca, who explains how the treaty was developed and what it will do.  It's an inspiring episode - enjoy!
