In this episode, we sit down with Lou Leonard, a veteran of the negotiations leading up to the Paris Climate Agreement, to unpack what that landmark deal got right, where it still falls short, and what's changed since. From the strategic logic behind keeping Paris non-binding, to the legal cornerstone of U.S. climate regulation known as the Endangerment Finding, we explore how climate policy is being reimagined at every level and what it really takes to drive meaningful action.

In this episode, we sit down with Alice Bazzano of Trivium Packaging to unpack the role of metal in the circular economy. From infinite recyclability to lightweighting and low-carbon aluminum, we explore how Trivium is navigating packaging design, policy, and consumer behavior to shape the future of sustainable materials, and what it really takes to move beyond plastic.

In this episode of Sustainability in Progress, we sit down with Michael Robinov, co-founder of Farm to People, to explore how food moves from farm to table, and who benefits along the way. We discuss the economics behind today’s food system, the decline of small farms, the limitations of organic labels, and how a shorter supply chain can better support farmers, reduce waste, and improve transparency for consumers.

New York City was once known as “the Big Oyster,” with oyster reefs playing a central role in the harbor’s ecosystem. However, overharvesting, industrialization, and pollution led to their collapse, but today, oysters are looking to make a comeback.In this episode of Sustainability in Progress, we speak with Charlotte Boesch of the Billion Oyster Project about their efforts to restore oyster reefs across New York Harbor. We discuss why oysters are a keystone species, how recycled shells from restaurants are transformed into reef habitats, and what it takes to grow and install millions of oysters in New York City's harbor.The conversation covers the science behind oyster filtration, the role reefs play in supporting biodiversity and reducing wave energy during storms, and the challenges of large-scale restoration.

The clean energy transition isn’t just about swapping fossil fuels for renewables, it’s about building a new energy system built for the future. In this episode, we speak with Tim Montague, solar developer, clean-tech advisor, and host of The Clean Power Hour. We’ll discuss the realities of the energy transition, the current state of battery storage, the growing issue of solar panel end-of-life and recycling, and the environmental footprint of mining the critical minerals needed for EVs and batteries. The conversation also tackles how AI is reshaping energy demand and grid resilience, and what it will take to build a cleaner, smarter power system for generations ahead.

From the farms that grow it to the cafés that fuel our mornings, coffee is one of the world’s most beloved and climate-vulnerable commodities. In this episode of SIP, we sit down with Etelle Higonnet, environmental advocate and founder of Coffee Watch, to unpack how rising temperatures, erratic rainfall, and shifting ecosystems are transforming global coffee production.We explore how climate change is affecting farmers’ livelihoods, what companies and policymakers are doing to adapt, and what the future of your daily cup might look like. So grab your favorite brew and join us for the conversation.Link to Coffee Watch petitions: https://coffeewatch.org/sign-petitions/

Today we had the opportunity to chat with the CEO of Natoora, Franco Fubini. Franco’s recent book, In Search of the Perfect Peach, explores how flavor and seasonality could hold the key to a more sustainable food system. He argues that when we push produce out of their natural seasons, we compromise taste, nutrient density, and the environment. We have also created a food system where our produce and fruit are increasingly flat, bland, and dull, and generally uninspiring. But the solution to more flavorful, rich, and sustainable produce might be within reach!

We are joined by Etelle Higonnet, who has an incredibly storied background and today, she shares her view on how the sector can become more sustainable, address environmental and social risks, and how we as consumers can make more informed choices. She is currently founding an NGO called Coffee Watch to reform coffee industry abuses like deforestation and slavery. Her work spans a broad range of environmental issues including climate, ecological agriculture, environmental justice and forest protection, and she has also dedicated a large portion of her career to human rights. And here’s the link to the Chocolate Scorecard Etelle discusses: https://www.chocolatescorecard.com/scorecards/

Welcome to our last episode of 2024! Today we speak with Henry Gordon-Smith, Founder and CEO of Agritecture, an advisory and technology firm specializing in climate-smart agriculture. Our conversation explores the prospects for vertical farming and climate smart agriculture in reducing the environmental impacts of food systems and the role of emerging technologies in reshaping the way we feed a growing population.

In our latest episode, we are joined by the explorer Andi Cross and dive deep (pun-intended) into her adventurous journey which blends her expertise in growth strategy with a passion for ocean conservation. Hear how she’s leveraging her unique background to empower organizations on the frontlines of climate change, particularly within the ocean nonprofit sector. From adrenaline-pumping blackwater dives to her upcoming Arctic ice dives, she shares captivating tales of exploration and the critical importance of coastal health for global communities. We also explore the double-edged sword of tourism—its economic benefits and its impact on ecosystems—and the importance of conscious exploration. We’ll also talk to Andi about how she selects her expeditions, focusing on partnerships with local stakeholders to support restoration efforts.
