Climate Rising

In this episode of Climate Rising, we explore how Netflix, a global entertainment powerhouse, is leveraging its platform to tell compelling stories about climate change. Stewart, Netflix's first Sustainability Officer, joins host Mike Toffel to discuss the company’s strategic approach to sustainability, the importance of embedding climate themes in popular content, and how these efforts aim to educate and inspire action among its vast audience. Stewart shares insights into the challenges and opportunities of incorporating climate considerations into both operations and storytelling, revealing how Netflix is contributing to the global climate conversation.

This episode is the first of our latest series on climate in media and entertainment, where we explore and understand the role of storytelling in shaping climate actions. Today we have Bill Weir, Chief Climate Correspondent at CNN who shares his expertise on how CNN integrates climate narratives into their news coverage, the power of storytelling, and the strategies they employ to highlight both the urgency of the climate crisis and the innovative solutions emerging worldwide.

Erik Snyder, Founder and CEO of Drawdown Fund discusses financing climate tech startups through growth equity. He describes how he started the Drawdown Fund with Paul Hawken, editor of the New York Times best-selling book on climate solutions called Drawdown, and the strategic choices that set their fund operations apart from others. He also describes some of the fund’s portfolio companies: from sustainable packaging, community solar to decarbonizing mass-transit with AI.

Fred Krupp, president of the non-profit Environmental Defense Fund (EDF), describes EDF’s work to address climate change through scientific, economic, and legal analyses, working with governments and companies, and public and legal advocacy for stronger climate and other environmental practices and policies. Fred joined us to talk about MethaneSAT, EDF’s new satellite that was recently launched to monitor emissions of methane, a potent greenhouse gas, from oil and gas operations. Fred describes why EDF entered the satellite business, how its satellite differs from others already in orbit, the many partners EDF enlisted to design and deploy the satellite, how AI is deployed in the process, and what new opportunities this satellite will provide for EDF and the rest of us.

Today’s episode focuses on some innovative alternative low-carbon natural materials being used in fashion. Bolt Threads CEO Dan Widmaier describes Mylo, a substitute for leather that’s derived from mushrooms, via the TED Climate podcast that we’re bringing here a bonus episode of Climate Rising. It’s a perfect extension of our two most recent Climate Rising episodes that focus on other low-carbon advanced materials: GALY’s lab-grown cotton and C16 Bioscience’s lab-generated treeless palm oil.

Today’s episode is the fifth in our series on decarbonizing the roots of value chains, where we’re looking deep into supply chains that serve many industries. Previously we talked about green concrete, green steel, regenerative agriculture, and lab-grown cotton. Today we’re discussing palm oil – a widely used product that’s also associated with climate change due to some palm oil plantations arising from clearing and burning tropical forests, releasing carbon and destroying habitat and biodiversity. We talk with Shara Ticku, Co-founder and CEO of C16 Biosciences (and HBS alumna), which uses fermentation to produce a palm oil substitute. She describes how she and her partners built their start-up, including how they decided which products to develop, and which customers to pursue. She also shares advice for those interested in working at climate tech startup companies like hers.

Today’s episode is the fourth in our series on decarbonizing the roots of value chains, where we’re looking deep into supply chains that serve many industries. Previously we talked about the technical products of green concrete and green steel, and agriculture through the lens of regenerative agriculture. Today we continue our focus on decarbonizing agricultural products by focusing on lab-grown cotton. Luciano Bueno, founder and CEO of GALY, joins me today to talk about how his biomaterials start-up uses sugar to feed cells and grow cotton in the lab. Luciano will share how he rebounded from a venture that failed, and then started GALY and grew it into the Series B company it is today. I’ll also ask him to share his views of the future of lab-grown fabrics and his reflections on entrepreneurship in climate tech more broadly.

Today’s episode is the third in our series on decarbonizing the roots of value chains, where we’re looking deep into supply chains that serve many industries. Previously we talked about green concrete and steel, and today we’re turning to agriculture. Chris Marquis, a professor at the University of Cambridge Judge Business School sheds light on regenerative agriculture, a set of practices that restore farming ecosystems while having the potential to decarbonize. We’ll also talk about his new book The Profiteers, where he discusses the need to hold companies accountable for the environmental and social externalities associated with their operations and supply chains, and he describes how some companies have engaged in what he calls “corporate gaslighting” to shift the focus of responsibility onto others.

This episode is a part of our series on decarbonizing the roots of value chains, where we’re looking deep into supply chains that serve many industries. Our prior episode explored green concrete, and today’s focuses on steel. Steel production primarily relies on coal and coke, and accounts for nearly 7% of global CO2 emissions. But new technologies are on the horizon. Maria Persson Gulda, Chief Technology Officer at H2 Green Steel, joins us to discuss an innovative solution: green steel made from green hydrogen. By harnessing renewable power, H2 Green Steel is pioneering a path to drastically reduce steel's carbon footprint. Maria will also share insights into the world’s largest green steel plant in Sweden H2 is building, the evolving technological landscape, and the pivotal role of initial adopters.

The first of a series on decarbonizing the roots of value chains, where we’re looking deep into supply chains that serve many industries, this episode focuses on concrete. Concrete is one of the world’s most popular materials, and it accounts for nearly 8% of the world’s greenhouse gas emissions, most of which comes from cement– the glue that binds conventional forms of concrete. We focus on one type of green concrete produced by Urban Mining Industries that replaces half of the cement with recycled glass that makes its product much less carbon intensive. We present this story through an episode of the HBR Cold Call podcast, where host Brian Kenny interviews HBS professors Shirley Lu and Bob Kaplan. They discuss how Harvard is pilot testing the use of green concrete in its current construction projects as part of the university’s efforts to reduce its carbon footprint. They’ll also discuss various methods to measure carbon emissions, including the e-liability approach Bob Kaplan lays out in a recent Harvard Business Review article.

In this episode in our adaptation series, Peter Hall, Managing Director at Resonance Impact Advisory, draws upon his experience in global engineering and professional services firms to share how consulting and advisory companies can help their clients assess their risks and take actions to become more resilient to climate change.

This episode in our adaptation series focuses climate change’s implications on the insurance industry. Claudine Blamey, Group Director of Sustainability at Aviva, describes how climate change evokes both transition risks and physical risks for insurance companies, and affects how insurance companies are assessing and pricing risk in their underwriting process, and influences their investment strategy. Claudine also describes innovative insurance products such as parametric and catastrophe insurance that are emerging to address natural disasters that are exacerbated by climate change.

This episode in our climate adaptation series features HBS Professor John Macomber. John discusses how companies and governments need to incorporate climate resilience as they develop and finance real estate and infrastructure to address the risks of flooding, wildfire, extreme heat, drought, and sea level rise. John describes “five R” options to address these risks—to reinforce, rebound, retreat, restrict, and rebuild—and highlights best practices from insurance companies and the governments of Amsterdam, Rotterdam, and Singapore. He also identifies entrepreneurial opportunities to foster adaptation and resilience.
