Sarah E. Light
Professor Light’s research examines issues at the intersection of environmental law and business innovation. Her articles have addressed the regulatory implications of the rise of transportation platforms like Uber and Lyft; how business innovation, such as Microsoft’s adoption of a private carbon fee, can be a form of private environmental governance; and the U.S. military’s role in stimulating private technological innovation to reduce fossil fuel use in what Light has called The Military-Environmental Complex. Her articles have appeared in and are forthcoming in the Duke Law Journal, the UCLA Law Review, the Vanderbilt Law Review, the Emory Law Journal and the Stanford Environmental Law Journal, among others.
In 2017, Professor Light was awarded the Excellence in Teaching Award in the MBA Program at Wharton. In 2016, Professor Light was one of ten faculty nominated by the MBA student body for the Helen Kardon Moss Anvil Award for Outstanding MBA Teaching.

This Brief focuses on ways in which private firms are adopting tools that mirror public law instruments—such as internal carbon fees (similar to a public carbon tax) and private cap-and-trade schemes (like public emissions trading schemes)—to reduce greenhouse gas emissions and address climate change. These private case studies suggest that significant progress in reducing emissions can come from embedding emissions reduction programs into core business strategy. Moreover, these case studies indicate that climate change, as a global issue, requires public regulators to recognize the potential contributions of global multinational firms.
Although the military’s operations are largely exempt from environmental laws and regulations when those laws conflict with its national security mission, the military has important incentives to reduce its reliance on fossil fuels and combat climate change. If nurtured properly, the military’s extensive undertaking to improve its sustainable energy use and reduce demand for fossil-fuel-derived energy has the potential to become one important tool in the environmental regulatory toolkit.
