Cleaning Up: Leadership in an Age of Climate Change

This summer, Michael Liebreich wrote two essays under the title of the Pragmatic Climate Reset. The first challenged the idea that the clean energy transition has failed. And the second challenged the clean energy and climate community to a reset, exploring eight areas which he thinks the transition has gone astray.In this special episode, Bryony Worthington sits down with Michael Liebreich, to unpack Part 2 of “The Pragmatic Climate Reset.”Michael lays out a bold vision for cutting through the noise — replacing ideology with realism, and paralysis with progress. From net zero targets and critical minerals to global politics, energy security, and the economics of clean tech, this is a conversation about what it takes to deliver a just and workable climate transition.Bryony asks Michael,Why criticise Greta Thunberg rather than call out anti-climate commentators like Joe Rogan or President Trump?Did he go too easy on the fossil fuel industry?What does he think he got wrong?How has the essay been received, and did he get any good feedback, either positive or negative.Michael puts forward the idea that if the transition is to succeed in the long run and keep the public on board, we must proceed as a tortoise, not a hare, building on the considerable momentum of renewables to phase fossil fuels out of our energy mix while also keeping energy affordable, and everyone’s lights on.Listen now, or watch the full episode on YouTube.Leadership Circle:Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

What does it take to rewire a nation’s energy system? Can we make the grid cleaner, smarter, and more resilient — without driving up bills? And how will the explosion of AI data centres reshape the future of electricity demand?This week on Cleaning Up, host Michael Liebreich sits down with John Pettigrew, outgoing CEO of National Grid, for a candid conversation marking the end of his 35-year career. Together they explore the UK’s £60 billion plan to deliver Clean Power by 2030, the race to build transmission for offshore wind, the growing strain from AI-driven electricity demand, and lessons from major outages in Spain and Heathrow.Pettigrew reflects on the evolving “energy trilemma” — balancing decarbonisation, reliability, and affordability — shares reflections from his 35-year career: what’s changed, what went wrong, and what comes next for the grids powering our clean energy future.Leadership Circle:Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Arup, Cygnum Capital, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

What does it take for India to deliver electricity to hundreds of millions while simultaneously building a fast-growing clean energy system? Can it overcome its fossil dependence to secure its energy futures with renewables? And how will India’s development choices shape the global climate fight in the decades ahead?India, like China, is home to over a billion people, and is highly reliant on imported fossil fuels and domestic coal. But unlike China, it still has a very rural population and has not yet experienced the rapid rise in per capita energy consumption that accompanied China’s recent development boom. The future path India takes to development is therefore of critical importance.In this episode of Cleaning Up, Bryony Worthington sits down with Dr. Arunabha Ghosh, founder and CEO of the Council on Energy, Environment and Water, and Special Envoy for COP30. Together they explore India’s “twin transition”, achieving universal energy access while driving a massive expansion of clean power. From the data-driven electrification of 130 million households, to innovations in market design that slashed solar prices, to India’s push for secure, diversified green supply chains, this conversation reveals a rarely told side of India’s energy transition story.Arunabha also shares insights on India’s role in international climate diplomacy, the significance of cooperation with China and Brazil, and the urgent need for hyper-local climate risk assessment to protect communities from extreme weather.Leadership Circle:Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

Why should we care about coral reefs? What happens when they collapse? And is there still hope for their survival?In this episode of Cleaning Up, Bryony Worthington sits down with coral reef ecologist Dr. Katharina Fabricius, who has witnessed six mass bleaching events on the Great Barrier Reef over her three decades of research.From the “seven sins of climate change” threatening reefs — heat waves, acidification, storms, nutrient runoff, and more — to the resilience and surprising adaptability of corals, Katharina offers a sobering yet hopeful look at the future of our oceans. Together, they explore the science, politics, and moral responsibility of protecting one of the world’s most critical ecosystems, and why the fate of coral reefs is deeply tied to human survival.Leadership Circle:Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

The election of Donald Trump to a second term as President marked a turning point in the politics of climate action – not just in the US, but around the world.The airwaves are suddenly awash with commentators, claiming that the transition has failed, that it was always a fool’s errand, and that we must resign ourselves to a fossil-based future forever.The narratives of failure all revel in pointing out that we have not seen dramatic cuts in fossil fuel use globally, consistent with keeping the temperature increase to 1.5C, and are not on track to achieve global net zero by 2050.The climate and clean energy community is facing a choice. It can remain reactive, doubling down on old narratives, pressing on with existing policies, preaching to the converted and watching the pace of change slow for the next few years.Or it can undertake what I call a Pragmatic Climate Reset: Wind back historical over-reach, accept harsh realities, address legitimate concerns, refresh its offer and find new ways of communicating with a confused public.Leadership Circle:Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

Is the future of clean energy and climate solutions brighter than we think? In this episode of Cleaning Up, Michael Liebreich welcomes back Hannah Ritchie — Deputy Editor at Our World in Data, researcher at the Oxford Martin School, and author of her new book, Clearing the Air.In Clearing the Air, Hannah tackles 50 of the most common myths and misconceptions about climate solutions, from “Isn’t climate action too polarised and politically divisive to fix?” to “What happens when the wind doesn’t blow?” and “Won’t the world run out of minerals?” Hannah dives into the data behind renewables, electric cars, nuclear power, grids, and even lab-grown meat — cutting through the noise with clarity.Michael quizzes Hannah on why she wrote the book and what she hopes to achieve with it, and whether it has the potential to change the minds of climate skeptics. This conversation offers a grounded, accessible look at what really works, what doesn’t, and why we should feel more hopeful than the doom-filled narratives suggest.Leadership Circle:Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Arup, Cygnum Capital, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

What happens when cheap solar flips the script on climate sceptics? Can pumped hydro really deliver the long-duration storage we need? And is “hope” a dangerous comforter in the race to net zero?In this season opener of Cleaning Up, Michael Liebreich sits down with Malcolm Turnbull — former Prime Minister of Australia, lawyer, statesman, energy investor, and climate champion. From leading Australia through fierce political battles over climate policy to now spearheading renewable projects through Turnbull Renewables, he offers a rare insider’s perspective on the global clean energy transition.Turnbull and Liebreich explore the clash between optimism and realism in climate action: why cheap solar is reshaping politics, the promise and pitfalls of green hydrogen, and whether pumped hydro could be the long-duration storage solution the world needs. Along the way, they reflect on U.S. politics under Trump, trade negotiations without American leadership, and why “hope is not a strategy” when it comes to energy security.Leadership Circle: Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Arup, Cygnum Capital, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

This episode was originally broadcast in April 2022Alex Honnold is one of the world’s best rock climbers, famous for his free solo ascents of big walls, including his 2017 first free solo of El Capitan in Yosemite.Alex began studies in engineering at the University of California-Berkeley but dropped out to pursue his passion for climbing, living out of his van. He first attracted attention within the climbing community in 2008 when he became the first climber to free solo Half Dome in Yosemite. In 2012 he established the speed record for the Yosemite Triple Crown, climbing three big walls in under 19 hours. With Hans Florine, Alex climbed the popular Nose of El Capitan, a nearly 3,000-foot granite wall, in a record time of two hours 23 minutes and 51 seconds – a feat National Geographic described as perhaps " the greatest feat of pure rock climbing in the history of the sport."Alex has been profiled by 60 minutes and the New York Times, appeared on the cover of National Geographic and starred in numerous adventure films. In 2015, together with professional climbing writer David Roberts, he authored Alone on the Wall, the story of seven of his greatest climbing feats up to that year.In 2012 Alex founded the Honnold Foundation to provide solar power to some of the disadvantaged communities he was coming across in his climbing career. In 2021 the Foundation supported 44 communities across 17 countries with its brand of community-centered innovation catalysed by solar energy.Links and more:Watch the video of this episode: https://youtu.be/MwmQf0mhHkEHonnold Foundation: https://www.honnoldfoundation.org/Free Solo Trailer: https://www.youtube.com/watch?v=urRVZ4SW7WUFree Solo website: https://films.nationalgeographic.com/free-soloThe Ascent of Alex Honnold – CBS special report with Lara Logan https://www.youtube.com/watch?v=SR1jwwagtaQEduro Corner: The most exposed move of Alex’s Free Solo climb of El Capitan https://www.youtube.com/watch?v=blfR33DUqsgProject Bo: https://www.projectbo.org/Project Bo, lessons learned: https://www.liebreich.com/project-bo-saving-lives-in-sierra-leone-with-solar-batteries-and-twitter/

What if the energy transition isn't a race, but a steady march toward the end of fossil fuel usage? Do we need to move more like the tortoise, and less like the hare? And in a world of competing narratives, who gets to define "pragmatism"?In this season finale of Cleaning Up, hosts Michael Liebreich and Bryony Worthington unpack these questions as they review Season 15's most compelling conversations about energy transformation, and celebrate five years of Cleaning Up. They dissect the current political landscape, particularly the challenges facing clean energy in the United States, and Bryony grills Michael on his recent Bloomberg essay on the "Pragmatic Climate Reset."This is the final episode of Season 15 of Cleaning Up, join us in September for the start of Season 16.Leadership Circle: Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

In February, veteran fossil industry advisor Dan Yergin and two co-authors published a piece called The Troubled Transition. In it they dismiss the idea that there is or can ever be an energy transition, anchored on the fact that fossil fuels contributed 85% to so-called primary energy in 1990 and still contribute 80% today. Needless to say, their argument has been widely amplified by the oil and gas industry. They conclude with a demand for a new approach – which they call a “pragmatic path”. Pragmatism is needed, but not the pragmatism of defeat. Not the ‘pragmatism’ of believing fossil fuels hold the key to further human progress. Not the ‘pragmatism’ of addressing climate change only if it suits the interests of fossil-fuel companies. What is needed is the pragmatism of robust but affordable climate action. This week on Cleaning Up, Michael Liebreich debunks narratives that trumpet the alleged failure of climate action, and explains why a pragmatic climate reset is needed.Leadership Circle: Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

Is the US about to enter a new era of energy inflation? Can technological progress outpace political regression? Are we witnessing the permanent end of America's climate ambitions?This week on Cleaning Up, Michael Liebreich sits down with Ethan Zindler, former climate counselor to Treasury Secretary Janet Yellen, now head of countries and policy at BloombergNEF, to dissect the dramatic shifts in US energy policy. Fresh from the passage of the "One Big Beautiful Bill," Zindler reveals how recent legislation in the US could set back clean energy development by years, potentially undermining investments in wind, solar and electric vehicles. There are a couple of brighter spots too, with costs in some technologies falling so rapidly that they might escape the drag of the current administration, and other technologies — like advanced geothermal and nuclear — seeing an uptick in support. Zindler brings the latest analysis from BloombergNEF to Cleaning Up to help unpack the One Big Beautiful Bill and what it means for the future of US energy policy.Leadership Circle: Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

⁠If the UK can’t ditch fossil fuels, who can? What impact would more drilling in the North Sea have for UK energy prices? What does the end of the net zero consensus mean for UK energy policy?This week on Cleaning Up, host Bryony Worthington sits down with Tessa Khan, founder of Uplift, a charity challenging the oil and gas industry's hold on UK energy policy. A lawyer turned campaigner, Khan offers incisive analysis of why the North Sea's fossil fuel era must end.Drawing from her background in international human rights and development, Khan reveals how the UK could become a global pioneer in energy transformation. She unpacks the economic myths perpetuated by the oil and gas lobby, exposes the minimal benefits of continued extraction, and champions a just transition to renewable energy.With the UK at a critical political crossroads, Khan offers a masterclass in strategic advocacy, blending data, political insight, and a passionate vision for a sustainable future. Leadership Circle: Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

What if the key to solving our climate crisis lies beneath our feet? Could tiny fungal networks be the unsung heroes of carbon sequestration? And how might reimagining our relationship with fungi transform our understanding of life on Earth? This week on Cleaning Up, Bryony Worthington sits down with Merlin Sheldrake, author of the bestselling "Entangled Life," to explore the extraordinary world of fungi. Sheldrake reveals how these remarkable organisms are not just passive participants in our ecosystem, but active innovators that have been shaping our planet for a billion of years. From their crucial role in carbon cycling and soil health to their potential in creating sustainable materials, fungi may be a powerful solution to some of our most pressing environmental challenges. Sheldrake takes us on a journey through fungal networks, discussing their intelligence, chemical capabilities, and symbiotic relationships that challenge our understanding of life. Leadership Circle: Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

In a world where 17% of all electricity is generated from wind and solar and where 93% of all new capacity added to the grid is from renewables, it can be easy to forget that countries got their first wind and solar resources within just the last few years. And in fact, some countries are still waiting for their first. Today on Cleaning Up, we’re joined by Daniel Calderon, Founder and Managing Partner of Alcazar Energy Partners. Daniel has made it a specialty of going into countries overlooked by others, building their first wind and solar farms, and as he explains, doing it profitably. Leadership Circle: Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

In 1849, when the Gold Rush hit California, the people who were certain to make money were not the miners, but the sellers of picks and shovels. Indeed, America's first millionaire, Samuel Brannan, made his fortune by adding huge margins to everyday items that suddenly become high in demand. Today's sellers of picks and shovels are those providing the hardware and infrastructure to the software and platform providers, and one company stands apart as the beneficiary of the recent boom times in artificial intelligence: Nvidia. They're currently among the top three listed companies in the US, alongside Apple and Microsoft, and are incredibly profitable, with estimated margins in excess of 40%. They've been around for 30 years, and are much more than simply chip fabricators. This week on Cleaning Up, Bryony Worthington sits down with Josh Parker, Nvidia’s head of sustainability, to explore some of the challenges and opportunities he sees in the AI and Climate space.Leadership Circle: Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

Oil and gas companies lie at the heart of the energy transition. To some, they are heroes, continuing to power human progress despite all the odds. To some, they are villains, responsible for the climate change that is devastating our planet. This week on Cleaning Up, Michael Liebreich interviews Ben van Beurden, former CEO of Shell from 2014 to 2023. The conversation explores the complexities of the energy transition, climate change, and the role of oil and gas companies in addressing global emissions.Van Beurden argues that there's no silver bullet solution to climate change, emphasizing the need for multiple approaches and a holistic view of energy transformation. He believes oil and gas companies will play a crucial role in developing clean energy solutions and driving systemic change, but ultimately we must move away from polluting fossil fuels in pursuit  of the prize of Clean Energy.Leadership Circle: Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.

The world's electricity system is transforming: We're integrating more and more variable renewables. Fossil plants are running fewer hours. Demand is growing everywhere, including in the developed world, as we electrify transport and heating, and AI data centers elbow their way onto the grid. Some people find this very threatening but not Antonio Cammisecra, CEO of ContourGlobal. CounterGlobal is a leading independent power producer who is well on their way to transition away from coal to electricity production based on renewables and gas. Antonio joins Michael on Cleaning Up to discuss how to build resilience and security in renewable-dominated grids, how ContourGlobal's battery storage systems are delivering solar at night, and why grids around the world are struggling to cope as electricity demand rises. Leadership Circle:Cleaning Up is supported by the Leadership Circle, and its founding members: Actis, Alcazar Energy, Davidson Kempner, EcoPragma Capital, EDP of Portugal, Eurelectric, the Gilardini Foundation, KKR, National Grid, Octopus Energy, Quadrature Climate Foundation, SDCL and Wärtsilä.
