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. We get into the science of how it works, why methane is the "low-hanging fruit" of climate action, and what it takes to turn a lab result into a commercial supply chain cattle farmers can actually use.

Chris also opens up on the funding journey, angel investment, equity crowdfunding, government grants, and where carbon credits fit into scaling a seaweed farm to thousands of hectares.

A great one for anyone who thinks climate solutions have to be complicated. Sometimes it's just seaweed.

Nic Seton is the CEO of Parents for Climate, the grassroots group that took on EnergyAustralia over "carbon neutral" greenwashing, and won.

In this episode, Nic joins Loreto and Dan to unpack what that landmark case really means for carbon offsets, ESG claims and corporate Australia in the era of mandatory climate disclosures. He also makes the case that parents are one of the most powerful and most overlooked forces for climate action in the country.

We get into:

•  the EnergyAustralia greenwashing case and the signal it sends on carbon offsets
• the "kids test" to pressure-test any climate decision at work
• how being a parent at work is a climate superpower
• how to get your business and community ready for a changing climate without burning out

Sustainability work is meaningful, but it can also break you. In this episode, we sit down with Courtney Kovac and Georgia Monaghan, co-founders of EcoMind, to talk about what happens when the people trying to save the planet burn out trying to do it.

Georgia and Courtney bring very different journeys to this conversation, one from climate law and consulting, one from youth mental health. Together they've built something that sits right at the intersection: practical tools for navigating the emotional toll of living and working through a climate crisis.

We talk about the difference between overwork and burnout, how to find agency when the outcomes feel out of your control, and why hope isn't naive, it's necessary. 

If you've ever felt like what you're doing isn't enough, this one's for you.

Our guest in this episode is Darren Umbers, MD ANZ and Global Head of Sustainability and ESG at Performance Health. 

We loved hearing about how Darren's path into ESG wasn't a straight line. He trained as a biomedical scientist, spent years on the commercial side of healthcare, and decided to come back to sustainability during COVID, when he had the space to realise he could use his influence for good.  Now he's leading the climate strategy for a 
global business from Australia. 

A few highlights you'll hear: 

• How the leader of an Australian subsidiary ended up leading global ESG
• A supplier engagement story every sustainability practitioner will recognise: a 25-page supplier survey that got no responses (and how he turned that around!) 
• Why climate data has become a condition of trade.
• How to build a climate champions network inside the company.

Whether you're navigating mandatory reporting, leading sustainability inside a multinational, or being handed an ESG remit on top of your existing role, there will be something of interest for you!

Hudson Worsley, Chair of MECLA (the Materials and Embodied Carbon Leaders' Alliance) joins us to unpack embodied carbon in construction. The emissions baked into every building, bridge, and data centre before they're even switched on. 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 together more than 160 partners across construction, infrastructure, government, and finance to drive down embodied carbon in concrete, steel, aluminium, and the buildings they go into.

We get into:

• Why government procurement is the single biggest lever for change in Australian construction, and why outcome-based targets beat input-based ones
• The impact of the data centre boom 
• Why concrete alone accounts for around 8% of global emissions, and would be the fourth-largest emitting country in the world if it were one
• Why "no" doesn't mean "never" when you're asking for low-emission materials, and how persistence has driven down the cost premium on low-carbon cement
• How the Anzac Bridge, built around the Sydney Olympics with 65% recycled industrial waste in its pillars, was quietly 30 years ahead of its time
• What AASB S2 mandatory climate reporting means for Scope 3 emissions across the construction value chain

Hudson's call to action is simple. Ask the embodied carbon question. Then ask it again. And again.

In a year defined by geopolitical volatility, fragmented climate policy and the rapid rise of AI, what should corporate leaders actually be paying attention to?

Dr. Matthew Bell, Group CEO of Anthesis, one of the world's largest sustainability consultancies, joins us to unpack the megatrends reshaping business, climate risk and sustainability in 2026.

From why TCFD quietly changed corporate decision-making to how Asia is out-competing the West on decarbonisation, Matt lays out what's actually moving the needle.. and what's not.

We also get into:

• Why the world's largest insurers and defence forces are the ones raising the loudest alarms.
• The $1.5 trillion AI investment vs the $700 billion nature funding gap.
• Australia's pattern of inventing breakthrough climate tech.. and letting others commercialise it.
• What separates companies leading on climate from those falling behind, and the concept of ROI Squared.
• The oil and gas client that set a genuine net zero strategy.. and what happened next.

A conversation for anyone working at the intersection of business, climate and capital.

In this episode, we sit down with Mick Liubinskas, Partner at Melomys and founder of Climate Salad and one of Australia's most connected voices in climate tech, to unpack why world-class Australian research so often fails to commercialise locally. With nine years bridging startups, clean tech, and corporate innovation, Mick shares hard-won lessons from Silicon Valley and Australia's own ecosystem of 800+ climate startups.

We explore how AI is transforming climate solutions, from grid optimisation and battery chemistry to biological applications like algae and phytoplankton. We dig into the structural barriers holding back local adoption, including procurement complexity, small-market dynamics, and corporate risk aversion. And we make the case for sustainability leaders to step up as innovation brokers, connecting founders with the right people, budgets, and problems inside their organisations.

Whether you're a sustainability professional navigating mandatory reporting, a corporate leader weighing build-versus-buy decisions, or just curious about where AI meets climate action, this episode is packed with practical insight.

In this episode, digital sustainability strategist Tim Prosser returns to The Green Fix to unpack the physical footprint of data centres — the invisible infrastructure behind every AI query, cloud service, and streaming session.

Tim breaks down what corporate sustainability professionals need to know right now: why data centres could consume 11% of Australia's electricity by 2035, what the CEFC's reliability gap warning means for energy prices (and your mortgage), and why annual offsets are no longer cutting it. He explains the shift to 24/7 carbon-free energy matching, the emerging water risks that have Sydney, Melbourne, and Hobart mayors sounding the alarm, and how direct-to-chip liquid cooling could halve data centre water use.

Plus: six metrics to see through greenwash, procurement moves ASX-listed companies can make today, and why your sustainability team needs to be talking to IT — yesterday.

Whether you're reporting under Australia's climate disclosure framework, managing ESG for a company with cloud infrastructure, or just trying to understand where the grid is heading, this one's essential listening.

What's the real environmental footprint of your organisation's IT infrastructure — and is your cloud provider telling you the full story?

In this episode, we welcome back Tim Prosser for part one of a two-part deep dive into digital sustainability. Tim is a specialist in digital sustainability strategy and green operations, with over 20 years leading enterprise technology teams across the UK and Australia. He serves as a mentor and community advisory board member at Climate Salad and led industry engagement at Climate Action Week Sydney in 2024–2025.

Since his first appearance on The Green Fix in June last year — one of our most popular episodes — Tim has been on a global study tour, connecting with digital sustainability practitioners across London, attending Climate Week, London Tech Week, and the Global Tipping Points Conference at Exeter University. He returns with sharp insights on what organisations need to know right now.

Tim unpacks why Australian cloud environments are rated E and F against the global standard, what questions organisations should be asking their technology suppliers before hard-baking data into baselines, and where the biggest gaps in IT emissions reporting sit — particularly in financial services, insurance, and media. He introduces the IT Sustainability Maturity Assessment by the global nonprofit Sustainable IT, and explains why the collaboration between sustainability, finance, and IT — what he calls the sustainability value triangle — is the key relationship for credible climate disclosure.

Whether you're a sustainability practitioner preparing for mandatory reporting, an IT leader navigating digital emissions, or someone who's never thought about the carbon footprint of their inbox — this episode is essential listening.

How can the Australian subsidiaries of global multinationals become sustainability innovators, rather than waiting for head office to lead the way?

In this episode, we sit down with Dani Matthews, Co-Founder and Chief Impact Officer at Abundium, a leadership community for C-suite executives in foreign-owned companies operating across the ANZ and APAC region. Abundium works with over 100 of the world's leading multinationals to drive what Dani calls "good growth", leadership that balances profit with people and planet.

We talk about leapfrogging (not the pilates kind): how Australian subsidiaries can use their distance from global headquarters as freedom to pilot, test, and innovate, then share those breakthroughs back to the global business. She shares how Unilever ANZ achieved B Corp certification before its parent company and piloted a four-day work week in New Zealand, and how DHL Supply Chain is using a global carbon insetting model to reduce supply chain emissions ahead of local infrastructure.

We also explore what Dani calls the Trusted Triangle , the critical alignment between the CEO, CFO, and Chief People Officer, and why sustainability must sit at the heart of business strategy, not on the sidelines. With mandatory sustainability reporting now underway in Australia, Dani shares what she's hearing from CFOs navigating the transition and why frustration might actually be the gateway to flow.

Whether you're in a multinational, an ASX-listed company, or a sustainability role looking for practical ways to keep this work on the leadership agenda, this conversation is full of actionable insights.
