Pharmaceuticals and personal care products can be found in every home in America, but now they are also showing up in our wastewater systems and even our lakes and rivers.

In this third episode of the Emerging Contaminants series, hear from Professor Bill Arnold (University of Minnesota), Eva Weiler (Shook, Hardy & Bacon LLP), and Victor Xu (Marten Law) as they explore how these everyday products are making their way into the environment. The discussion also covers potential regulatory responses, including the possible U.S. ban of titanium dioxide—already prohibited in the EU—and the growing concern over pharmaceuticals and nanoparticles from personal care items polluting our waterways.

In the second installment of our Emerging Contaminants series, we turn our attention to ethylene oxide, a chemical critical to the sterilization of medical and protective equipment yet increasingly scrutinized for its potential carcinogenic effects due to widespread use and long industrial history.

In this episode, we’re joined by Rebecca Pritchett (Maynard Nexsen), Heather Lynch (Integral Consulting), and David Fusco (K&L Gates) to examine the latest developments in ethylene oxide science, regulation, and litigation. Our guests discuss recent findings and interpretations suggesting that human health risks from ethylene oxide exposure may be lower than previously thought—a perspective that continues to generate scientific, legal, and policy debate.

In 2024, key legal and regulatory shifts transformed the ESG landscape across the U.S., Canada, U.K., and EU. In the U.S., the SEC adopted—and later stopped defending—climate disclosure rules, while the Department of Labor’s ESG rule faced litigation and Congress advanced anti-ESG bills. At the same time, the EPA began deploying $27 billion under the Greenhouse Gas Reduction Fund, and youth-led climate lawsuits saw major wins.

California’s climate reporting laws (SB 253, SB 261, AB 1305) faced challenges but remained in effect, and greenwashing litigation expanded to cover broad corporate ESG claims.

Internationally, the U.K. introduced mandatory Biodiversity Net Gain rules, the EU implemented the CSRD and CSDDD, and Canada passed a new Modern Slavery Act. Together, these changes mark a global move toward greater corporate transparency and environmental accountability.

Join Josh Galperin, professor at the Elisabeth Haub School of Law, in conversation with Lauren Lynam and Morgan Martin as they unpack the year’s most significant ESG legal developments across the U.S. and beyond.

In the debut episode of our Emerging Contaminants series, we examine the widespread presence of microplastics in our environment, including in human and animal bodies and throughout our food systems. Because microplastics originate from larger plastic products, regulatory efforts have targeted the broader plastic lifecycle: from manufacture, import, and export to use, labeling, recycling, and disposal - with particular attention to single-use plastics.

Join panelists Jennifer F. Novak (Law Office of Jennifer F. Novak), Talia Gordner (McMillan LLP), and Usha Vedagiri (WSP) as they discuss recent developments in plastic regulation, including the United Nations plastics treaty and efforts in the European Union and Canada, and share insights into what may lie ahead for the United States.

In the wake of the Los Angeles fires and amid a growing wildfire crisis, Doug Green, manager of Headwaters Economics’ Community Planning Assistance for Wildfire (CPAW) program, joins Andrew Kihn, programming vice chair of the Forest Resources Committee, for a conversation about the L.A. fires, the broader wildfire emergency, and the political and regulatory landscape of wildfire management in the United States. They discuss persistent challenges facing communities in the wildland-urban interface (WUI) and highlight best practices for improving wildfire preparedness in both the built environment and America’s forested lands.

Join Tim Kelly (Hausfeld) and Misha Tseytlin (Troutman Pepper Locke) as they unpack the U.S. Supreme Court’s landmark decision in City and County of San Francisco v. EPA. The ruling struck down the EPA’s use of “end-result” requirements in NPDES permits, ruling that the Clean Water Act (CWA) does not authorize the agency to impose permit conditions that hold dischargers responsible for overall water quality in receiving waters. The decision has significant implications for municipal wastewater treatment, regulatory enforcement, and the scope of the EPA’s authority under the CWA.

In this episode, they explore:

• The legal reasoning behind the Court’s decision, including highlights from the majority and dissenting opinions

• The implications for municipal wastewater treatment plants, particularly those operating combined sewer systems

• How the decision impacts the EPA’s regulatory powers and enforcement strategies

• What this means for the future of Clean Water Act litigation and the evolving role of state environmental agencies

Whether you're a legal practitioner, environmental policy expert, or simply interested in water law, this episode offers valuable insight into a pivotal case reshaping federal environmental regulation.

The National Environmental Policy Act (NEPA) landscape is shifting fast. With major developments like Eagle County, Marin Audubon, Section 5 of President Trump’s Unleashing American Energy Executive Order, and several critical cases on the horizon, the way NEPA is applied and interpreted is set for a major transformation.

Join Susan Jane Brown (Silvix Resources) in a thought-provoking discussion with Ted Boling (Perkins Coie Partner, former member of the Council on Environmental Quality) and Dinah Bear (former General Counsel of the Council on Environmental Quality). Together, they’ll break down these pivotal changes, what they mean for environmental policy, and how NEPA’s role may evolve in the years ahead.

Don’t miss this essential conversation for legal professionals, policymakers, and anyone invested in the future of environmental law.

In the third episode of the Mill Closures and Workforce Shortages in the West series, Andrew Kihn is joined by Susan Jane Brown, Principal and Chief of Silvix Resources, a nonprofit environmental law firm. Together, they explore the implications of the ongoing workforce challenges on the conservation, stewardship, and restoration of western public lands. The two discuss the often fraught relationship between communities dependent on timber harvest and conservation interests, and Susan Jane Brown elucidates the opportunities and imperatives of coalition building across the divide. 

In the second episode of the Mill Closures and Workforce Shortages in the West series, Andrew Kihn returns, joined by Travis Joseph, President and CEO of the American Forest Resource Council. Together, they delve into the role of land management policies in addressing workforce challenges from the perspective of the timber trade association.

Building on the foundation laid in the first episode, this discussion highlights how policy solutions can mitigate the workforce shortages tied to the ongoing closures of lumber mills in the American West. Travis Joseph provides insights into how these closures impact both the timber industry and the broader regional economy, offering actionable approaches to support sustainable forest management and workforce retention.
