Emerging contaminants are by their nature neither fully regulated nor fully understood.

In this final episode of the Emerging Contaminants series Juge Gregg (Crowell & Moring), Sal Giolando (Geosyntec Consultants, Inc.), and Adam Sowatzka (McGuire Woods) discuss how to assess emerging contaminants in your supply chains to identify potential substances that may be subject to further regulation or increase the risks associated with business operations.

This episode explores how companies monitor and manage their supply chains through advanced technologies and strategic practices to prevent regulatory breaches and enhance transparency, ensuring they remain compliant and competitive in a global marketplace.

While we all notice the emissions exiting our vehicle's tailpipes, the emissions from brake dust and tire wear are often overlooked.

Scientists are now turning their attention to these lesser-known pollutants, which are emerging as significant environmental concerns. As studies begin to grasp the extent of such impacts from automotive use on our environment, we discuss how regulation of these materials and emissions may impact our existing regulatory scheme and the auto industry as a whole.

In this fourth episode of the Emerging Contaminants series, Jack Lyman speaks with Professor Greg Evans (University of Toronto) and Sean Dixon (Puget Soundkeeper) as they explore the role of contaminants like 6PPD and what future regulations might mean for the automotive sector.

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 (K&L Gates), 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.
