A New Era? Private Sector Leadership in Environmental Law

Is environmental law entering a new era—one defined not just by regulation and litigation, but also by implementation, incentives, and private-public partnerships?In this episode of People, Places, Planet, host Sebastian Duque Rios is joined by Roger Martella (Chief Corporate Officer and Chief Sustainability Officer at GE Vernova), Mike Vandenbergh (Professor of Law, Vanderbilt University), and Linda Breggin (Senior Attorney at the Environmental Law Institute) to examine how climate and environmental governance is evolving amid political gridlock and regulatory uncertainty.Building on Martella’s 2024 law review article, the panel traces three eras of environmental law and explores the growing role of private environmental governance—driven by corporate investment, supply chains, investor pressure, and accountability to employees and customers. They discuss the risks and realities of greenwashing, what this shift means for environmental professionals, and how large-scale capital deployment is shaping the energy transition and climate action today. Join us for a forward-looking conversation for environmental professionals navigating the future of environmental law and policy.A new era of environmental law?

As artificial intelligence drives unprecedented growth in electricity demand, data centers are rapidly becoming some of the largest—and most consequential—loads on the U.S. power grid. Utilities that haven’t seen meaningful load growth in decades now face mounting interconnection backlogs, rising costs, and growing concerns about reliability, emissions, and equity.In this episode of People, Places, Planet, host Sebastian Duque Rios is joined by Dalia Patino-Echeverri of Duke University and Aroon Vijaykar of Emerald AI to explore whether load flexibility offers a way forward. They examine how data centers and AI stress today’s grid, how modest and carefully designed curtailment could unlock significant new capacity without overbuilding infrastructure, and what emerging technologies and policies—from flexible interconnection to software-driven demand response—could mean for electricity affordability, grid reliability, and the future of AI development in the United States.The Driving Forces Behind a New Wave of Electricity Demand (2:12)What's Constraining the Grid?

From the food we eat to the parks, farms, and neighborhoods around us, pesticide policy quietly shapes everyday life in the United States.In this installment of our Explained series on the nation’s foundational environmental laws, we turn to the Federal Insecticide, Fungicide, and Rodenticide Act, better known as FIFRA. Host Sebastian Duque Rios is joined by Dr. Jennifer Sass of the Natural Resources Defense Council and Keith Matthews of Matthews Law LLC to unpack how pesticides are regulated in the United States, why FIFRA was created, and how it has evolved from a consumer protection statute into a central health and environmental safeguard.Together, they walk through how EPA evaluates pesticide risks and benefits, what “unreasonable adverse effects” really means in practice, and how FIFRA interacts with food safety law and state authority. The conversation also explores the role of labels and enforcement, the promise and limits of safer alternatives like biopesticides, and the pressures facing pesticide regulation today—from staffing shortages to faster approval timelines. Whether you work in environmental law or are just trying to understand how pesticides are regulated, this episode offers a clear understanding of how FIFRA affects what ends up on our food, in our environment, and in our bodies. ★ Support this podcast ★

As 2025 comes to a close, People, Places, Planet takes stock of a year of profound change in environmental law—and looks ahead to the legal and policy questions that will shape 2026.

Environmental justice continues to evolve as states respond to shifting federal priorities and community needs. New Jersey has emerged as a leader, integrating equity considerations into core environmental programs, supported by its landmark 2020 EJ law and a long-standing emphasis on strong environmental protections.In this episode, New Jersey Department of Environmental Protection Commissioner Shawn LaTourette joins Beveridge & Diamond’s Hilary Jacobs and Justin Smith to discuss how the state is operationalizing EJ, measuring progress, and adapting to the major changes in federal policy and funding with the new Administration. Commissioner LaTourette outlines how New Jersey incorporates environmental justice into decision-making, the practical work of translating EJ principles into concrete, data-driven actions, and the challenges of aligning state and federal roles. The conversation also explores support for community-based organizations, funding constraints, and how businesses can navigate evolving EJ frameworks. This episode is part of the Groundtruth series created in partnership with Beveridge & Diamond, one of the nation’s leading environmental law and litigation firms. ★ Support this podcast ★

At a time when species across the country face mounting pressures, the Endangered Species Act remains one of the most powerful—and contested—tools we have to protect them. In this installment of our Explained series, host Sebastian Duque Rios is joined by three experts whose careers span law, policy, and conservation science: Patrick Parenteau (Vermont Law & Graduate School), Jake Li (Defenders of Wildlife), and David Wilcove (Princeton University).Together, they break down how the ESA works, why it was created, and the real-world threats species face today. The conversation explores key provisions of the Act—from listing decisions and critical habitat designations to Section 7 consultations, recovery planning, and the role of private landowners. The guests also discuss how funding shortfalls, political pressures, and recent proposals could reshape endangered species protection in the years ahead.Whether you’re new to the ESA or looking for a richer understanding of its legal, scientific, and practical dimensions, this episode offers a clear and candid look at the challenges and opportunities facing one of the nation’s cornerstone conservation laws. ★ Support this podcast ★

As climate change reshapes our oceans, fish populations are shifting across borders and into new territories, creating ripple effects for food security, livelihoods, and international relations. These changes are intensifying pressure on governments and coastal communities—and, in some cases, fueling tension and conflict at sea. In this episode of People Places Planet, host Sebastian Duque Rios speaks with Johan Bergenas, Senior Vice President for Oceans at the World Wildlife Fund-US, and Sofia O’Connor, Director of the Environmental Law Institute’s Ocean Program, about the complex links between marine conservation, illegal, unreported, and unregulated (IUU) fishing, and international security. Together, they explore how climate-driven migration of fish stocks can trigger disputes between nations, how data and transparency tools like WWF’s Oceans Futures platform can help policymakers anticipate and prevent those conflicts, and how legal frameworks can promote cooperation rather than conflict on the high seas.See WWF's recent report, The Geopolitics of the Ocean, as well as their Oceans Futures platform for more information. ★ Support this podcast ★

As the first U.S city to implement a congestion pricing program, New York City has begun charging vehicles entering high-traffic areas of Manhattan a toll. With this initiative, NYC is testing what could be a consequential urban policy for transportation and climate at the municipal level. Ten months into the program, what have we learned? In this episode of People Places Planet, host Sebastian Duque Rios speaks about congestion pricing with Robert Puentes, Vice President and Director of Brookings Metro; Rachel Weinberger, Vice President for Research Strategy and the Peter W. Herman Chair for Transportation at the Regional Plan Association; and Christine Billy, Adjunct Professor of Clinical Law at NYU and Executive Director of the Guarini Center. Together, they unpack NYC's congestion pricing program: why it was pursued, how it works, what early data suggests about its impacts, and the waves of legal challenges that the program has faced. In discussing how this innovative policy aims to rethink urban mobility, the conversation delves into how congestion pricing connects to broader environmental and public health goals, including the reduction of greenhouse gas emissions, and how it can present a model for other cities looking to fund and improve public transit.  ★ Support this podcast ★

What does it mean to “indigenize” international law—and why does it matter for the environment? In this episode of People, Places, Planet, host Sebastian Duque Rios speaks with legal scholars Jonathan Liljeblad, Kristen Carpenter, and Margaret Palaghicon Von Rotz about how Indigenous peoples are reshaping international legal thought. Together, they explore the concept of Indigenous legal orders—living systems of law that exist alongside and often in tension with state-based international law—and their growing influence in environmental governance. From the Ifugao people’s stewardship of the Philippines’ rice terraces to the Yurok Tribe’s river restoration and land back efforts in California, the conversation highlights how Indigenous nations are asserting legal authority across state borders, revitalizing relationships to land and water, and challenging colonial legacies in our legal systems. This episode offers a powerful look at what international law could become when Indigenous legal systems are recognized as active, evolving sources of law shaping the planet’s future. ★ Support this podcast ★
