We make our best attempt to sum up all the thrills and spills of week two of COP30, and boy there were some twists in the tale: a resolution to Australia’s bid to host COP31 that no-one had on their bingo card; literal conflagrations in the COP30 pavilions; and arguably the most dramatic closing plenary of any COP, ever.

We woke up expecting to record an episode about how to run a successful COP, but news reports suggested Australia may not get to host a COP at all! So ably assisted by Alex Scott – longstanding COP maven and current Senior Associate for Climate Diplomacy at the climate think tank ECCO – we talk a bit about the bid and ways for Australia to maintain a leadership position in a scenario in which it doesn't hold the presidency, the latest from the negotiations on the Big Four™️, and take some live questions from the audience.

So we're in Belém, Brazil for COP30 where the weather is humid, the caipirinhas are delicious, the NDCs are insufficient and the action agenda is extensive! Thats right folks, we're summing up all the colour and movement of week one, with a particular focus on the procedural gambit of the Brazilian Presidency that saw the 'Big Four' issues (what a pithy coinage that is, hey T?) that threatened to bog down agreement on the negotiating agenda allocated to their own special “informal backroom consultations”, immediately rendering said consultations far more interesting that the primary negotiations! 

Featuring: special guest co-host Josh Gabbatiss from Carbon Brief! Also featuring: perhaps our final (we feverishly hope so) round of COP31 host speculation!

With COP30 in Belem, Brazil only days away, your intrepid hosts dive into recent remarks from UN Secretary General, António Guterres, widely reported as ‘the world has missed 1.5C’, the reality being much more nuanced commentary from this climate champion as he enters his final year as Secretary General. Undoubtedly, it feels like a threshold moment as he acknowledges the world has breached 1.5C. We are now in the realm of overshoot, but the longer term of objective of stabilising temperature increases to 1.5C is still possible - keeping 1.5 alive - but only if we redouble efforts to focus on decarbonisation here and now, and flags the need to ramp up efforts on negative emissions. Significant remarks and food for thought on the real and difficult choices ahead!

Our main course

Is it 1965 or is what’s old new once again folks? Your intrepid hosts wade into the technical, controversial, futuristic yet bafflingly bootstrapped proposition that is geoengineering - shooting stuff into the sky and blocking out some sunlight, cooling the earth’s surface. What could possibly go wrong?! Well, this paper, ‘Engineering and logistical concerns add practical limitations to stratospheric aerosol injection strategies’ published in Nature and authored by Miranda Hack, V. Faye McNeill, Dan Steingart and Gernot Wagner, has some thoughts! Engineering challenges? Yes! Cost? What better use of diamond dust could there be! Governance issues? A few! What is incredibly clear from reading this paper is that there are no easy decisions when it comes to the need to consider negative emissions technologies or other novel ways of moderating temperature increases. Could it be that on closer inquiry, we should just focus on getting on with decarbonising, or is more research required?

Tennant’s One More Thing is: more ranting about data centres! Tennant has questions about the ultimate viability of the eyewatering numbers of speculative capacity in new data centre growth, as well as the equally worrying implications for viability coal closures if much of this does come to pass. Bubble or not, we’ll find out soon enough!

Frankie’s One More Thing is: a massive shout out and thanks to 150 fabulous folk that fronted up to Chaos Trivia last week in Melbourne, including ultimate winners, No One Likes A Gentailer. Props to our co-hosts Currently Speaking, our MC extraordinaire Mark Spencer and The NEMChat Singers who added colour, movement and grooves to the chaos! With all proceeds going to the brilliant First Nations Clean Energy Network there was much to love.  

Luke’s One More Thing is: a definitely-not-resentful readout of the paper he really wanted us to read this episode, IRENA’s ‘Delivering on the UAE Consensus: Tracking progress toward tripling renewable energy capacity and doubling energy efficiency by 2030.’ TL;DR is we’re going gangbusters on solar but woeful progress on energy efficiency. More to do!

With a promise to provide guidance on the next five years ‘and beyond’ your intrepid hosts digested the Queensland Government Energy Roadmap 2025. It provides a major reset in some respects with continuity in others. Grabbing the headlines was the telegraphed decision to run government-owned coal assets to end of technical life but much detail still ‘TBC’ when it comes to how decisions on coal will be made.Transmission is getting a big overhaul, renewables still gonna be big but maybe not so much on the wind front. More questions raised than answered here for now as Luke is left pondering the wisdom of scrapping a bicameral parliament in the great northern state!

Our main course

With a tantalising title of ‘Bills Down, Emissions Down: A practical path to net zero electricity’ your intrepid hosts are having what the Grattan Institute is serving! A timely provocation from Alison Reeve, Tony Wood, Dominic Jones and Ben Jefferson on the value - and they argue necessity - of reinstating a price on carbon in the electricity sector. The world has changed since the last time carbon pricing was discussed in the energy sector and the folks from Grattan argue the Safeguard Mechanism presents a ready made vehicle to get the job done. And they don’t forget to remind us of earlier work in their report Climate Phoenix that shows how the Safeguard could evolve into a broader emissions trading scheme, Much food for thought ahead of the 2026-27 Safeguard review!

Tennant’s One More Thing is: his appearance at an event hosted by the University of Adelaide, festively titled, ‘Livin La Vida BoCA’! No guesses as to what that was about: a whisper of chat about border carbon adjustments and our man Mr Reed manifests!

Luke’s One More Thing is: the long awaited and celebrated launch of the Commercial Building Disclosure Roadmap! *Finally* After previous reviews gathered dust on shelves, we finally have a plan for expanding use of Australia’s globally leading NABERS rating scheme in disclosing the nergy performance of more building types.

All aboard folks! Team LMSU is embarking on a BoCo odyssey over the the next couple of months, adventuring through each of the six sector decarbonisation plans. AND we’re bringing friends! That’s right, we’re calling in even nerdier reinforcements and experts to join us as we venture on. For our first deep dive, The Planned and the Penurious (Energy and Electricity Sector Plan), we were joined by Energy wizard Dylan McConnell! Our second outing, 2 Planned: 2 Penurious (Built Environment), will feature buildings maven Davina Rooney!

While it’s no Planned and the Penurious, your intrepid hosts have been following the final laps of the NDC Grand Prix as a flurry of countries have raced (?) to lodge their 2035 Nationally Determined Contributions (NDCs) under the Paris Agreement. China’s commitment to cut emissions 7–10% below peak levels by 2035 is dissected: an under promise, over deliver scenario? Almost certainly based on their track record. India is progressing through the pack, Europe stuck in the pit lane with internal negotiations, the US is doing doughnuts in the car park, and what on earth do we make of the corner-cutting of Russia’s retrograde move? And what about the two-thirds of countries still in the garage that haven't even gotten around to submitting a climate pledge yet? Is this Trump Administration dirty pool? Luke thinks maybe, Tennant is sceptical, but it certainly makes for an interesting COP and raises questions about the Paris Agreement’s “ratchet” mechanism and the consequences (or lack thereof) for backsliding or just ghosting the party altogether. We commend you to Climate Resource’s NDC country snapshots as a handy dandy resource!

Our main course

One of your intrepid hosts may have described reading the recently published National Climate Risk Assessment as ‘eating our climate risk vegetables’ given the dense and confronting nature of this 250+ page report. But jokes aside, team LMSU wanted to shine a spotlight and give our listeners a sense of the breadth and depth of this significant piece of work from Australia’s Climate Service: fifty six nationally significant climate risks across eight key functional systems, with seven additional risks highlighted for Aboriginal and Torres Strait Islander peoples. Eleven risks receive deeper analysis, assessed across three warming scenarios (1.5°C, 2°C, 3°C) and three time horizons (2025, 2050, 2090). While your intrepid hosts read the whole thing cover to cover, we reckon it’s designed as a more modular report and for those interested, we suggest reading the executive summary and use the table of contents to navigate to areas of interest. 

This paper reaffirmed the ‘why’ many of us are working in climate and energy and team LMSU is thinking of all you Summerupperers out there, more power to your arms!

Ladies and Gentlemen, we have a target! Your intrepid hosts reflect on the many and varied reactions to the slick and stage managed birthing of the Climate Change Authority’s advice on a 2035 target and the Government’s acceptance of their advice to adopt a target of 62-70% emissions reduction on 2005 levels by 2035. 

Simultaneously declared “Economy wrecking” (Opposition), “Weak and disappointing” (Greens) and “The sweet spot” (Prime Minister Albanese), it looks like business groups broadly land in the “benign toleration” camp and environment groups unhappy with the bottom end of the range. What do we reckon? The real debate starts now on the level of ambition needed in the policies to get to the top of the range—especially since current policies only get us to about 51% by 2035.

Looking for fodder for your own opinion? Check out the op-eds penned by Luke and Adam Morton, and Adam's conversation with CCA Chair Matt Kean.

Our main course

It wasn’t just the targets the Government served up last week that had your intrepid hosts salivating at the degustation menu of climate policy offerings to sample. Treasury modelling, NDCs, sector plans, OH MY! 

But y’all know the LMSU crew can’t resist the sweet tantalising temptation of a seriously nerdy modelling exercise and so it was decided - there was never really any question - to the Treasury buffet we go! With three scenarios to unpack, a friendship of climate models used - TIM, MIRA, EMM, ALEX, anyone? There was a lot to digest in here! 

Eye watering economic upsides for green exports, signalling on declining fossil fuel exports, the cost of delay and some seriously refreshing honesty about limitations of modelling, there was something for everyone here and some significant foundations being laid for the future debate of climate policy in Australia.

Targets! Targets! Targets! Have we reached peak 2035 target fever? You betcha, and it’s a smorgasbord with climate and business groups serving up their preferred target. Which one is just right? From the bottom-up analysis from EY with practical can-do actions to achieve 65-75% to Deloitte’s top-down analysis for Business for 75 suggesting a 75% target would grow the economy more than a 65% target, there was one bit of modelling the subject of much chatter, and that didn’t recommend a particular target at all! McKinsey’s modelling for the BCA took a look at modelled costs for achieving 50, 60 and 70% targets but omitted any analysis of benefits, didn’t consider global impacts and seemed to make some drastic assumptions about the impact on gas exports (but hard to know as no assumptions were published). The verdict? BCA seems to be trying to thread the needle in navigating different members’ views and… it could have been worse!

Our main course

This week your intrepid hosts pack the passports and FIFO into that GST-sapping, resource-rich, beachy utopia that is WA as we soak up Marian Wilkinson’s Quarterly Essay, ‘Woodside vs The Planet: how a company captured a country’. This cracker of an essay unpacks the complex relationship between Woodside, successive WA and Federal governments, and local communities. A particularly nuanced and sensitive account of impacts to the Murujuga people’s struggle for influence in the preservation of their cultural heritage is contrasted with accounts of shareholder action and activists calling out the cognitive dissonance from Woodside in claiming support for climate action while expanding plans for fossil gas extraction and export well beyond 2050. This was not the policy solutions paper Tennant wanted it to be, but we debated the merits of supply-side activism to shut down fossil fuel exports and whether the WA community would even be on board with that. This essay paints a vivid picture of Woodside’s omnipresence in WA and for a bunch of blow-in east coasters, we learned a lot!

Productivity Palooza 2025 continues like the perpetual festival the PC wished for and your intrepid hosts round up some of the big-ticket climate and energy related outcomes of Jim Chalmers’ roundtable. Environmental approvals? Hot to trot, before 2025 is out! Road user charging? Definitely happening, but only for EVs for now! Unlocking more investment from Aussie super funds? I spy with my little eye a performance benchmark test redesign! 

And what of the National Construction Code pause and reform? The suggestion of a lengthy pause to NCC updates resulted in exasperated bemusement at the boneheadedness of it all from climate folk, subsequently tempered by what was announced, a more modest pause until 2029. The verdict? Maybe focusing on the fact the NCC itself was a productivity reform is a good start, and while we’re at it, avoid scapegoating energy efficiency changes that save households money. AI to streamline the code and everything else will clearly save us all! 

Our main course

It’s time for some game theory as these beautiful minds leap into the climate geopolitics multiverse of Michael Mehling’s paper, ‘In The Vortex Of Great Power Competition: Climate, Trade and Geostrategic Rivalry in U.S.-China-EU Relations’. We take the green pill and immerse ourselves in three different universes, from a ‘Race to the Top’ where competitive cooperation drives climate innovation, to ‘Geopolitical Fragmentation’ where nationalism stalls progress and maybe leads to thermonuclear war? And the most intriguing of all, ‘Reversed Leadership’ where China leads the global decarbonisation charge, taking the mantle of global leadership from the US. China looms large across all three scenarios, driven by its increasing dominance in clean tech, but parts and combinations of all three scenarios are entirely plausible today. This short, timely paper packs a lot of punch!
