There's groundbreaking new science to help cut methane emissions, but is there the political will?

Harvard Kennedy School Professor Robert Stavins and Professor Daniel Jacob of Harvard’s School of Engineering and Applied Sciences are at the forefront of new efforts to monitor and control methane, a potent greenhouse gas. It used to seem like methane wasn't such a big deal. It was that other climate gas, the one that was the butt of cow flatulence jokes and that only stayed in the atmosphere for a decade or so. But since important global warming targets are now just 7 years away and science has developed a better understanding of both methane’s pervasiveness and its potent role in warming the atmosphere, it’s now very much on the front burner for increasingly concerned climate policymakers. The good news is that the science of monitoring methane emissions has taken huge leaps forward recently, thanks to advances in supercomputing, weather modeling, and satellite imaging, to the point where we could soon have daily real-time monitoring and measuring of methane emissions around the globe. Our two guests are playing an important role in that effort. Robert Stavins is an economist and the director of the Harvard Environmental Economics Project and the Harvard Project on Climate Agreements. Daniel Jacob was named the world’s top environmental scientist last year by Research.com and his groundbreaking work has been instrumental in creating methane monitoring systems so precise they can track emissions to a specific company or another individual source—from space. Both say that the need to address the methane issue is urgent and that the countries of the world now have the wherewithal to get methane emissions under control. There are hopeful signs, including a major international agreement called the Global Methane Pledge, but the big question will be whether global leaders have the will to follow through.

Robert Stavins is the A.J. Meyer Professor of Energy & Economic Development, Director of Graduate Studies for the Doctoral Programs in Public Policy and in Political Economy and Government, Cochair of the MPP/MBA and MPA/ID/MBA Joint Degree Programs. He is the Director of the Harvard Environmental Economics Program and the Harvard Project on Climate Agreements. He is a Research Associate at the National Bureau of Economic Research, a University Fellow of Resources for the Future, former Chair of the U.S. Environmental Protection Agency's Environmental Economics Advisory Board, and a member of the editorial councils of scholarly periodicals. His research has examined diverse areas of environmental economics and policy and has appeared in a variety of economics, law, and policy journals, as well as several books. Stavins directed Project 88, a bipartisan effort cochaired by former Senator Timothy Wirth and the late Senator John Heinz to develop innovative approaches to environmental problems. He has been a consultant to government agencies, international organizations, corporations, and advocacy groups. He holds a BA in philosophy from Northwestern University, an MS in agricultural economics from Cornell, and a PhD in economics from Harvard.

Daniel Jacob is the Vasco McCoy Family Professor of Atmospheric Chemistry and Environmental Engineering in the School of Engineering & Applied Science at Harvard University. His research covers a wide range of topics in atmospheric chemistry, from air quality to climate change, and has led the development of the GEOS-Chem global 3-D model of atmospheric composition. In 2022, he won both the Best Scientist Award and the Environmental Sciences in United States Leader Award from Research.com as the top environmental scientist in the world. Jacob has also served as a mission scientist on eight NASA aircraft missions around the world and was awarded NASA’s Distinguished Public Service Medal in 2003. Jacob has trained over 100 Ph.D. students and postdocs over the course of his career. In 1994 he was made a Fellow of American Geophysical Union (AGU) and was awarded the James B. Macelwane Medal. He holds a Ph.D. in Environmental Engineering from Caltech.
