In this week’s episode, host Daniel Raimi talks with Simon Greenhill (PhD candidate at the University of California, Berkeley) and Hannah Druckenmiller (university fellow at Resources for the Future and assistant professor at the California Institute of Technology). Along with other coauthors, Greenhill and Druckenmiller recently published an article in the journal Science that uses a new machine learning model to predict which waterways are regulated under the Clean Water Act according to different definitions of what the Clean Water Act calls “waters of the United States.” Greenhill and Druckenmiller discuss the differences in regulation when considering a broader or narrower interpretation of waters of the United States, along with the implications for wetland protection, clean water, and flood mitigation.

In this week’s episode, host Daniel Raimi talks with Lisa Rennels, a PhD candidate at the University of California, Berkeley, about a class of synthetic industrial chemicals used in air-conditioners, refrigerators, and other technologies: hydrofluorocarbons. Rennels discusses the proliferation of these chemicals in recent decades, the cost of hydrofluorocarbon emissions to society, the feedback loop between global warming and increased use of these chemicals for air-conditioning, and global efforts to reduce the emissions of hydrofluorocarbons.

In this week’s episode, host Daniel Raimi talks with Brad Harris, the director of government affairs at Resources for the Future, about the increasing demand for electricity in the United States. Harris discusses the main sources of this surge in electricity demand, also known as load growth; the challenges that load growth poses to goals for reducing greenhouse gas emissions that have been set by utilities and the United States; and tools available to utilities and policymakers that can help meet growing demand and mitigate the effects of load growth on ratepayers and emissions.

In this week’s episode, host Kristin Hayes talks with Fernando Vidal, a postdoctoral researcher at the Polymat research institute in Spain, about technological and policy options to create a more sustainable plastics economy. Vidal discusses the greenhouse gas emissions associated with the life cycle of plastics, changes to the chemical makeup and recycling of plastics that could reduce the impact of plastics on communities and the environment, and international efforts to reduce the negative impacts of the plastics economy. Vidal shares recommendations for a more sustainable plastics economy from an article that he coauthored, which recently was published in the journal “Nature.”

In this week’s episode, host Daniel Raimi talks with Travis Roach, an associate professor and director of the Central Policy Institute at the University of Central Oklahoma, about how the prevalence of air pollution may increase the incidence of fatal traffic accidents in the United States. Roach discusses the characteristics of airborne particulate matter that is 2.5 microns in diameter or less, which is air pollution known as PM2.5; the sources of PM2.5, including coal- and natural gas–fired power plants, vehicle tailpipe emissions, and wildfire smoke; the negative effects of PM2.5 exposure on physical health and cognitive functioning; and policies and technologies that can help reduce public exposure to PM2.5.

Pollution Causes Crashes: Particulate Matter and Traffic Accidents, with Travis Roach

In this week’s episode, host Kristin Hayes talks with Sebastian Blanco, editor-in-chief at SAE Media Group and a journalist on the automotive and vehicle-technology beat. This episode jump-starts a multipart series on electric vehicles (EVs), including the most practical matters that EV users need to know. In this first episode of the series, Blanco discusses the foundations of EV ownership. He covers different EV makes and models, the logistics of charging EVs at home and on the road, pro tips for locating charging stations through smartphone apps and other resources, and insights on EV maintenance based on his experience. Future episodes dive deeper on battery technology, charging stations, and driver experience. Listen in and stay tuned for those additional episodes in this series! Please let us know if we’ve missed any questions that you’re curious about; we may address those in a future podcast episode or blog post. And if you’re not interested in EV-ery detail, then tune back in after a few weeks, when we’ll return to our normally scheduled programming, which covers all kinds of topics in environmental economics.
