Plastics Without Borders: Inside Us
2026/06/09
This week’s bonus episode comes from South by Southwest London, where Earth Set and the Blue Earth Summit hosted a live discussion exploring one of the most overlooked dimensions of the plastics crisis: human health.
Guest names:
Sian Sutherland - Host, Founder of A Plastic Planet
Saabira Chaudhuri - Author of Consumed
Laura Harnett - Founder, Seep
Amir Afshar - Founder, Shellworks
Professor Richard Lea - University of Nottingham
The conversation moves beyond familiar debates about litter, recycling and ocean pollution to examine what happens when plastic becomes part of our bodies. From declining fertility and endocrine-disrupting chemicals to the history of single-use plastics and the challenge of building viable alternatives, the discussion brings together scientists, entrepreneurs, campaigners and journalists to ask a difficult question: if the evidence around plastic’s health impacts continues to grow, what will it take for business, policymakers and consumers to respond?
Along the way, the panel explores how plastics became embedded in modern life, why recycling is not the answer to solving the crisis, and whether a new generation of materials and business models can reduce our dependence on fossil-fuel-based plastics without creating new problems of their own.
In This Episode You'll Learn:
• How endocrine-disrupting chemicals found in plastics can interfere with the body’s hormonal systems and reproductive health
• Why scientists are increasingly concerned about declining fertility rates, falling sperm counts and rising reproductive disorders
• How exposure to certain chemicals during pregnancy may affect health outcomes later in life
• The surprising history of how plastics transformed consumer behaviour, packaging and modern convenience
• Why plastic production continues to grow despite decades of recycling campaigns and public awareness efforts
• What critics argue is wrong with today’s recycling system — and why many believe reduction and reuse must play a larger role
• How entrepreneurs are developing alternative materials designed to replicate the benefits of plastic without creating persistent waste
• Why regulation, economics and consumer expectations remain major barriers to scaling plastic-free solutions
• Whether human health concerns could become the catalyst that finally accelerates action on plastic pollution and chemical safety

Decarbonise or Deindustrialise? Is This Really the Choice Facing Britain?
2026/05/18
This week’s episode comes from Octopus Energy HQ where Amy Rennison is joined by Phil Cohen, Patrick Matthewson, Rachel Fletcher, and Aruna Ramsamy.
The conversation explores a growing tension at the heart of the UK’s industrial strategy: the push to decarbonise heavy industry is running directly into some of the highest industrial electricity prices in the OECD. Across steel, chemicals, manufacturing and energy-intensive production, the technologies for deep decarbonisation increasingly exist — but the economics, infrastructure and policy frameworks are not yet aligned to deploy them at scale.
What emerges is not a simple trade-off between climate ambition and industrial survival, but a more complex systems problem: fragmented policy design, high energy system costs, and weak demand signals are all shaping investment decisions in ways that risk slowing both electrification and industrial renewal. Against this backdrop, international examples like Sweden’s H2 Green Steel highlight how low-cost power, coordinated policy and long-term offtake agreements can unlock entirely new industrial ecosystems.
The central question becomes whether the UK can correct these structural issues quickly enough to prevent a gradual erosion of its industrial base while still pursuing net zero.
In This Episode You'll Learn:
• Why UK industrial electricity prices are among the highest in Europe and how policy costs, network investment and market design contribute to them
• How energy-intensive sectors like steel, chemicals and glass are already experiencing output declines linked to the energy crisis
• Why electrification is widely seen as the main route to industrial decarbonisation, despite technical limits in some high-temperature processes
• How fragmented policy between energy, industrial strategy and regulation is slowing investment and creating uncertainty for manufacturers
• Why compensation schemes and exemptions only partially offset high costs and fail to address structural competitiveness issues
• How projects like H2 Green Steel in Sweden demonstrate the importance of low-cost electricity, carbon pricing and coordinated demand for enabling new industrial investment
• Why investors and manufacturers are increasingly calling for deeper market reform, including connection reform, flexibility markets and removal of policy costs from electricity bills

Earth Set Q1 Climate Review: What Just Happened
2026/04/20
This week’s episode takes a step back from individual topics to look at the bigger picture: a Q1 2026 review of the climate and energy stories that have defined the year so far — and what they mean for what comes next.
Hosted by Amy Rennison, the conversation brings together three returning perspectives spanning analysis, politics and capital. Lucy Shaw, energy analyst and advisor, breaks down the system-level dynamics shaping energy markets and infrastructure. Luke Shore, from Project Tempo, explores how these shifts are landing politically, and how voters are responding. And Max Bray, partner at Kindred Capital, offers a view from the investment side, tracking where capital is flowing and where confidence is changing.
Across five fast-moving topics, from AI-driven energy demand to US climate policy, capital flows, the Iran crisis, and UK energy strategy, the discussion builds a picture of a system under pressure from multiple directions at once.
What emerges is a transition no longer defined by a single narrative. Instead, it’s shaped by competing forces: rapid demand growth, geopolitical instability, political backlash, and uneven progress across technologies and regions.
At the centre is a familiar tension, now more visible than ever: the need to move quickly, and the growing risk that rising costs, infrastructure constraints, and political resistance could slow things down.
If the transition is no longer just about decarbonisation, but about affordability, security and public consent, the question becomes: can the system adapt fast enough to hold all three together?
In this episode you’ll learn:
Why AI has rapidly shifted from a tech story to an energy and infrastructure story
How Europe’s economic fundamentals are affecting its ability to scale climate technologies
Whether we are actually on track for net zero — and how that depends on how you define “on track”
Why electrification — not just clean power — is now the critical missing piece
How the Iran crisis is affecting global energy markets, supply chains and pricing
How high energy prices are affecting UK industry — from steel to ceramics
Why delivery — not just policy — is now the key challenge for governments
How crises like today’s energy shock compare to historical moments like the 1970s oil crisis
Why moments of disruption can either accelerate change — or be missed entirely

The Just Transition: Making it Work
2026/04/13
This week’s episode comes from Octopus Energy HQ, where Amy Rennison hosts a live Earth Set conversation on one of the most contested — and least clearly defined — ideas in the transition: the “just transition”.
She’s joined by three perspectives spanning community, policy and capital. David Powell from the Local Storytelling Exchange brings a grounded view from communities across the UK, exploring how people actually experience change — often in ways that never show up in policy. Grace Millman, working on just transitions and community energy at Regen, looks at how fairness, participation and regional inequality shape the way net zero lands in real places. And Jordan Fletcher, investor at Future Impact Ventures, shares how capital can be deployed not just to decarbonise, but to create broader social and economic value from the start.
The conversation moves beyond theory into the lived reality of the transition: rising energy bills, contested infrastructure, uneven access to new technologies, and the growing sense among many communities that change is happening to them, not with them.
Together, they unpack a central tension: the need to move fast — and the risk that moving fast without fairness ultimately slows everything down.
If the transition is as much about trust, perception and lived experience as it is about technology, the question becomes this: how do we design a system that people actually feel is working for them?
In this episode you’ll learn:
Why the “just transition” means different things to different people — and why that ambiguity matters
How feelings of fairness, pride and dignity shape public support for climate action
Why most people don’t talk about “climate” — but do care about their homes, bills and communities
How storytelling reveals the gap between policy design and lived experience
The role of trust — and why people are more likely to act on advice from someone they know than from institutions
Why speed vs fairness is a false trade-off — and how unfair transitions often stal
How infrastructure projects like grid expansion are creating tension in local communities
Why energy bills remain the dominant lens through which people experience the transition

What the UK Is Getting Right: Geothermal Energy and Future-Focused Policy
2026/04/06
This week’s episode comes from the Eden Project in Cornwall, where Amy Rennison and Fiona Howarth speak to two very different — but equally important — voices in the transition.
First, Augusta Grand, CEO of Eden Geothermal, shares the story of bringing geothermal energy to the UK — from early resistance to wind power through to the realities of drilling, financing and scaling a new energy source. The conversation explores why geothermal has long been overlooked, how rapidly the technology is advancing, and why it could play a critical role in both electricity and heat.
Then, Amy speaks with Jane Davidson, former Welsh minister and architect of the Wellbeing of Future Generations Act — one of the most ambitious pieces of sustainability legislation in the world. They discuss how the Act came to life, what it has changed, and how it is now shaping Wales’ approach to long-term decision making and net zero.
Together, these conversations explore two sides of the same challenge: how we move from ambition to delivery — whether that’s building new energy infrastructure or redesigning the systems that govern it.
If the transition depends on both technology and institutions, the real question becomes this: how do we align innovation, policy and people to actually deliver change at scale?
In this episode you’ll learn:
What geothermal energy is and why it has been underutilised in the UK
How advances in drilling technology are rapidly improving the economics of geothermal
The difference between geothermal for electricity and geothermal for heat — and why heat matters most
Why countries like France, Germany and the Netherlands are ahead on geothermal deployment
The role of government policy, funding and market design in unlocking new energy technologies
How local energy systems, data centres and grid constraints are shaping future infrastructure decisions
What the Wellbeing of Future Generations Act is and why it is unique globally
The shift from a “duty to promote” to a “duty to deliver” in public policy
How long-term thinking is embedded into Welsh governance across all public institutions
Real-world examples of how the Act has influenced procurement, planning and community outcomes
Why political systems struggle with long-term decision making — and how this can change
How Wales is approaching net zero through a delivery-focused, system-wide plan
The importance of making climate policy tangible, practical and accessible to the public

The People Problem at the Heart of The Green Transition
2026/03/30
Behind every climate solution lies a human challenge.
A challenge not just of technology or capital, but of people — the skills, training and pathways needed to turn ambition into reality.
In this episode, Fiona Howarth sits down with Rich Tyrie, CEO of GoodPeople, to explore the growing green skills gap and what it will take to close it.
From building talent pipelines to connecting local communities with meaningful work, Rich shares insights from over a decade of experience working at the intersection of employment, social impact and the energy transition.
The conversation explores why millions of workers will need to be reskilled, why the current system struggles to keep up, and why solving the skills gap is as much about coordination and collaboration as it is about education.
If the transition to net zero depends on people, the real question becomes this: how do we build a workforce ready to deliver it?
Why the UK needs millions of workers to be reskilled for the energy transition
What the “green skills gap” actually means — and why it’s bigger than most people think
How labour market fragmentation makes it harder to match people with opportunities
Why many “green jobs” aren’t obvious — from scaffolders to finance roles
The difference between “dark green” and “light green” skills
Why education systems struggle to keep pace with changing workforce demands
The role of employers in shaping future talent pipelines
How social value and procurement are influencing business behaviour
Why early engagement with schools and young people is critical
How place-based approaches can unlock more inclusive access to jobs
What’s driving collaboration in regions like Greater Manchester
Practical ways individuals can explore and access green careers today

Bridging the Valley of Death: Scaling First-of-a-Kind Climate Tech in the UK
2026/03/23
Behind every breakthrough climate technology lies a quieter, more fragile moment. The point where innovation has been proven, but scaling it into the real world becomes uncertain, expensive and deeply complex.
In this episode, Amy Rennison sits down with Sarah Macintosh of Cleantech for UK and Jim Totty of Virdis Capital to explore one of the most critical — and least understood — challenges in the climate transition: the “first-of-a-kind” gap, often referred to as the valley of death.
Drawing on their recent research with Cleantech for UK, the conversation unpacks why so many promising climate technologies struggle to reach commercial scale, despite strong early innovation and growing global demand.
From funding gaps and capability challenges to risk perception and policy design, this episode explores the systemic barriers holding back the next generation of industrial climate solutions — and what it will take to unlock them.
If the technologies to decarbonise already exist, the real question becomes this: why are so few of them making it to full-scale deployment?
In this episode you’ll learn:
What “first-of-a-kind” projects are and why they sit at the hardest stage of climate innovation
Why the transition from pilot to commercial scale is so difficult for climate tech companies
The funding gap between venture capital and infrastructure finance — and why it persists
How founders must shift their narrative from “innovative and unique” to “bankable and low-risk”
The critical role of offtake agreements, supply contracts and project finance structures
Why internal capabilities — from leadership teams to technical validation — can make or break scaling
How the UK compares to the US, Europe and Asia in supporting climate technology deployment
The impact of energy prices and market structures on where projects get built
What policy tools (like contracts for difference, procurement and guarantees) can unlock progress
Why ecosystem fragmentation — across investors, corporates, government and service providers — remains a major barrier
The scale of the UK’s pipeline of climate projects and where the biggest opportunities lie
Why this is not just a capital problem, but a systems and coordination challenge

Volt Rush: How China Won the Battery Race
2026/03/16
Behind every electric car sits a far older and more complex story. A story about minerals, mining, geopolitics and a global race to control the materials that power the energy transition.
In this episode, Fiona Howarth sits down with Henry Sanderson, Financial Times journalist and author of Volt Rush, to explore the hidden history of electric vehicles and the critical minerals that make them possible.
From the early experiments of Thomas Edison and Henry Ford, to the rise of lithium-ion batteries and China’s dominance of global battery supply chains, Henry unpacks how electric vehicles became viable and why the competition for minerals like lithium, cobalt and nickel is now shaping global politics.
The conversation explores how China built its battery industry, why Western countries are scrambling to catch up, and why the clean energy transition still depends heavily on mining, metals and industrial supply chains.
If the world is electrifying everything, the real question becomes this: who controls the materials that make electrification possible?
In this episode you’ll learn:
The surprising early history of electric cars and why they nearly won the race against gasoline vehicles over a century agoHow lithium-ion batteries unlocked the modern EV revolutionWhy minerals like lithium, cobalt, nickel and graphite are essential to the clean energy transitionHow China built dominance across the global battery supply chainWhy Western countries struggle to finance new mining projectsHow geopolitics, trade policy and subsidies are reshaping the EV industryThe tension between sustainable mining and the massive demand for critical mineralsWhat the next generation of battery technology and energy storage could look likeResources & Links

Carbon Removal for Sale: What’s Real, What’s Hype, and Who Pays?
2026/03/09
What if one of the most important industries for solving climate change barely exists today?
The world is getting better at reducing emissions. Renewable energy is scaling. Electrification is accelerating. Efficiency is improving.
But even in the most optimistic climate scenarios, billions of tonnes of carbon dioxide will still need to be removed from the atmosphere every year.
In this Earth Set conversation, Amy brings together three experts working on the emerging carbon removal economy to unpack what that actually means.
Codie Rossi, Director of Carbon Management and Markets at the Clean Air Task Force, works on the policy frameworks shaping carbon removal markets.
Richard Barker, Partner at Counteract, advises investors and companies on carbon strategy and the realities of scaling climate technologies.
Swarnali Mitra, Director at CUR8, builds portfolios of carbon removal projects for corporate buyers navigating the early market.
Together they explore how carbon removal works, why it’s becoming central to climate strategy, and why building this industry could be one of the largest economic transitions of the coming decades.
Humanity emits roughly 55–60 billion tonnes of greenhouse gases every year.
Most climate pathways now suggest the world will also need 5–15 billion tonnes of carbon removal annually to stabilise global temperatures.
Today, we remove only a tiny fraction of that.
This conversation explores the gap between those numbers, the technologies trying to close it, and the financial and policy systems that will determine whether carbon removal becomes a defining industry of the 21st century.
In this episode you’ll learn
Why cutting emissions alone won’t be enough to stabilise the climateWhat carbon removal actually is and how it differs from carbon capture and offsetsWhy the world may need billions of tonnes of removals every yearHow approaches like direct air capture, mineralisation and ocean-based removal workWhy carbon removal markets are still at a very early stageThe financing challenge of building projects before buyers existHow corporate buyers are helping to create early demandWhy measurement, verification and trust are critical to scaling the sectorHow carbon removal could become embedded across industries from agriculture to constructionWhy this conversation matters
Carbon removal sits at the intersection of climate science, finance, technology and policy.
If the world is serious about stabilising atmospheric carbon levels, a whole new industrial system will need to be built to remove CO₂ and store it safely.
That system is only just beginning.
Understanding how it might develop is key for investors, policymakers, founders and anyone interested in the future of climate solutions.

Greenlash: Understanding Climate Change Opposition
2026/03/02
If two thirds of the public believe climate change is real, support renewables, and want government action… why does it feel like net zero is suddenly on shaky ground?
At February’s Earth Set Live, we took on one of the most consequential shifts in the transition right now: the rise of climate opposition inside mainstream politics.
This was a serious look at what’s actually driving the backlash. Energy bills. Industrial decline. Security fears. Media narratives. Political realignment.
Fiona Howarth was joined by:
Luke Shore, Deputy CEO at Project Tempo
Alex Carr, Deputy Director at Clean Air Task Force (CATF)
Sam Hall, Director of the Conservative Environment Network
Together, they unpacked what’s really happening beneath the headlines.
In this episode you’ll learn:
Why public belief in climate change remains high — but urgency has slipped behind cost of living pressuresHow energy prices became the fault line in UK climate politicsWhy “net zero” polls worse than “climate action” — and what that means for communicationWhat’s behind the growing divide between Conservative voters and Conservative leadershipWhether Clean Power 2030 is a strategic masterstroke or a political vulnerabilityThe industrial trilemma facing Europe: decarbonise, stay competitive, keep industryWhy renewables curtailment has become such a powerful symbol in the debateWhether moving levies from electricity to gas would ease the pressure or inflame itHow media framing shapes public perception more than most climate advocates admitAnd whether democracy is capable of delivering long-term climate strategy in short political cyclesKey threads that emerged
Affordability now drives the politics.
The debate has shifted. It is no longer primarily about whether climate change is real. It is about who pays, when, and how much.
Climate is now industrial strategy.
Energy security, supply chains, clean manufacturing and geopolitical competition are shaping climate policy as much as emissions targets.
Market design may matter more than targets.
Grid reform, storage, electrification incentives and pricing structures could determine whether the transition accelerates or stalls.
Public support is not collapsing.
Despite louder opposition voices, broad support for climate action remains resilient. The challenge is reconnecting the transition to tangible everyday benefit.

Climate Tech at the Start of 2026
2026/02/23
What actually happened in UK climate tech investment last year?
At our second live recording of Season Two, hosted at HSBC Innovation Banking during the Blue Earth Investment Forum in January, we brought the data to the table. No anecdotes, no gossip. Just numbers, trends and a candid look at what they mean for 2026.
Amy was joined by Sarah Mackintosh, Director at Cleantech for UK, and Sammy Fry, Head of Climate Tech at Tech Nation. Between them, they track thousands of startups, billions in capital flows, and the policy frameworks shaping the sector.
The headline? 2025 was not the collapse some feared. Total equity funding reached £3.9bn, debt and project finance continued to grow, and the UK remains surprisingly stable relative to its size.
But beneath that surface stability, there are deeper shifts. Early stage deals are down. Hardware investment has fallen sharply. The Series A and B “valley of death” remains a structural challenge. Meanwhile, AI continues to absorb a growing share of venture capital.
This conversation unpacks what is actually happening, where the pressure points are, and where opportunity may be building quietly.
In this episode you’ll learn:
Why 2025 was stronger than many expected, yet still worrying beneath the surfaceWhat the decline in seed and Series A funding means for the pipelineWhy hardware startups are facing a 70%+ drop in investmentHow energy and power continue to dominate climate capital flowsWhether AI is crowding out climate tech, or simply reshaping itThe role of Innovate UK, the British Business Bank and the new National Wealth Fund\Why food, agriculture and human health may be the next frontierWhat investors should actually focus on in 2026From patient capital to policy gaps, from energy prices to food security, this is a grounded look at the mechanics behind the green transition.
If you work in venture, policy, startups or climate innovation, this is one to bookmark.

Slow Burn: Why We Can’t Quit Coal
2026/02/16
Coal feels like history. Steam engines. Sooty faces. Museums and memorial plaques.
And yet it still generates around a third of the world’s electricity and accounts for roughly 37 percent of global carbon emissions. Every year, we burn close to one tonne of coal per person on Earth.
In this live recording from Octopus Energy & Octopus EV HQ, Fiona Howarth unpacks why coal refuses to fade quietly into the past.
Joining them are two exceptional guests:
Lucy ShawEnergy investor and advisor. Founder of an energy and climate investment consultancy. Former infrastructure investor at Blackstone, Actis, Vena Energy and the IFC (World Bank Group). Former BCG consultant and ExxonMobil engineer. Fulbright Scholar with an MBA from Harvard Business School and an MPA from the Harvard Kennedy School. Lucy is currently writing a book titled Slow Burn on the global persistence of coal.
Dr Sam GeallAssociate Fellow at Chatham House and Senior Visiting Research Fellow at the Oxford Institute for Energy Studies. Former CEO of Dialogue Earth (formerly China Dialogue). Specialist in China’s climate and energy transition, with a PhD in Social Anthropology and deep expertise on how energy, politics and industrial policy intersect in China.
Together, they explore a question that sounds simple and turns out to be anything but:
If coal is dirty, deadly and increasingly uneconomic, why are we still using so much of it?
Why coal still supplies around one third of global electricity
Why absolute coal use keeps rising, even as its share of the mix falls
How coal contributes an estimated 37% of global carbon emissions
Why China is simultaneously building record amounts of renewables and new coal capacity
How energy security, industrial policy and political legitimacy shape China’s coal strategy
What’s driving India’s continued expansion of coal
Why coal has become a culture war issue in the US
The role of jobs, identity and community in coal regions
Whether the UK really has “moved on” from coal, or simply offshored it
Why carbon capture is unlikely to rescue coal at scale
What a just transition actually looks like, and why most countries are still struggling to deliver one
Coal is declining in some regions. It is expanding in others. In many places, it is both shrinking and growing at the same time.
One thread ran through the entire conversation: coal is not just an energy source. It is a social system.
The question is not simply how to shut coal down. It is how to do so without hollowing out the places that built their lives around it.

2026/02/14
Earth Set is back! Can you believe we're on season 2 already?! We can't!
Season 1 started as an experiment. A few live conversations. A microphone in the room. A question about whether the climate transition could be discussed with more depth and less theatre.
Ten episodes later, it became clear there was an appetite for honest conversations about how the green transition actually happens.
Season 2 builds on that momentum.
In this trailer, Fiona and Amy reflect on some of the standout moments from Season 1, from Jamie Arbib’s expansive vision of a world shaped by abundant clean energy and artificial labour to sharp, data-led debates on net zero progress, geopolitics and environmental destruction.
Then we look ahead.
Season 2 opens with a hard look at coal. Despite progress in countries like the UK, coal still accounts for 37% of global carbon emissions . We unpack why China continues to rely on it, what that means for the global energy system, and why this conversation still matters.
We dive into climate tech investing in 2025, hosted alongside Blue Earth and Zinc at the Blue Earth Investment Forum . Which sectors are attracting capital? Where is early stage funding tightening? What does the data suggest about 2026?
We explore the politics of climate language and the surprising gap between public perception and reality. In the UK, people believe net zero will cost around 14,000% more than official estimates . At the same time, public concern about climate change remains strong. The challenge is clarity, cost and credibility.
Coming up this season:
Susannah Fisher on global adaptation and what happens if 1.5°C slips out of reach• Henry Sanderson on critical minerals, geopolitics and the supply chains behind the energy transition• A live conversation on carbon removal and the funding pathways shaping its futureEarth Set brings together founders, investors, policymakers and thinkers working at the centre of climate and business. The aim is simple: understand what is working, what is not, and what needs to happen next.
Season 2 launches on 16 February.

Green Crime: Why Environmental Destruction Is a Criminal Problem
2025/12/22
Environmental destruction is often framed as harm, oversight, or bad practice. But what if we started calling it what it really is. Crime.
In this season finale of the Earth Set podcast, we are joined by Dr Julia Shaw, criminal psychologist, author, podcast host, and presenter, for a conversation that reframes how we think about crimes against the planet.
Julia is the author of Green Crime, a global investigation into the psychology behind environmental crime. Drawing on cases from around the world, she explains why these crimes keep happening, who commits them, and why society consistently underestimates their severity.
From corporate scandals like Dieselgate to illegal mining, poaching, and organised crime at sea, Julia shows how environmental crime is systemic, enabled by weak enforcement, social norms, and very human behaviour.
In this episode you’ll learn:
Why environmental crimes are treated as lesser crimes, and why that matters
The six psychological drivers behind environmental crime
How corporate and organised environmental crimes really operate
Why enforcement and regulation are critical to accountability
How psychology can help change behaviour, not just policy
This episode marks the end of Season 1 of Earth Set. Thank you to everyone who has listened, shared, and joined us so far. Season 2 and more live events are coming in the new year.

Net Zero’s Breaking Point: The Talent Shortage
2025/12/15
In this episode we continue our Green Skills audio only series. Fiona speaks with Mat Ilic, CEO of Greenworkx, an organisation building the workforce needed to deliver the transition. Mat’s work sits at the intersection of industry, social impact and public policy, and he brings one of the clearest views on what the UK must do to avoid a skills bottleneck that could slow climate progress for years.
The scale of the challenge is stark: around 4 million workers will need to retrain in the next five years if the UK is to stay on track for net zero. Some jobs will disappear. Others will transform. Entirely new sectors will emerge, from low carbon heating to home energy upgrades to the electro technical work that underpins everything from data centres to EV charging.
This conversation dives into what it will take to build a workforce capable of meeting that moment.
🔍 In this episode you will learn:
Why the workforce gap is becoming one of the biggest risks to net zeroWhy electrical skills sit at the heart of almost every part of the transitionThe real barriers stopping people from retraining, from cost to confidence to information gapsWhy employers need policy stability to hire and invest in skills at scaleWhat a fair and inclusive transition looks like for workers at every stage of their careerHow Greenworkx is creating new pathways into roles that did not exist a decade agoWhether you are an employer, policymaker, L and D leader, or someone exploring a move into the green economy, this is a practical and ambitious guide to one of the most urgent challenges of the transition.
