In this week’s episode, host Daniel Raimi talks with Arvind Ravikumar, an assistant professor at the University of Texas at Austin, about recent federal deregulation of methane emissions in the United States; specifically, the effects on methane emissions from the production of natural gas and liquefied natural gas. Ravikumar highlights some of his recent research, which explores how all steps in the supply chain of natural gas can affect emissions intensity—including transportation of the energy source to end users—and the variation in methane emissions across countries from their natural gas supply chains.
