Environment & Climate Change

Economic historian Emma Rothschild, the Jeremy and Jane Knowles Professor of History at Harvard, lauded the efforts of young scholars to discover local solutions to mitigate the impacts of global climate change in the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program.” The podcast is produced by the Harvard Environmental Economics Program.

Stephen Walt advises that in order to prepare students of public policy schools for a rapidly changing world, faculty should teach historical cases where the prevailing theories led to bad policy choices, and where new ones had to be devised to address a novel set of circumstances. 

Joseph S. Nye argues that history shows that globalization is largely driven by technological changes that reduce the importance of distance, and that will not change.

The economist and HKS professor is passionate about solving what may be humanity's most important and perplexing problem: How to untangle fossil fuels from the global economy.

While the Paris Agreement provides the framework for the nations of the world to slow the growth of CO2 emissions, additional policy and technological tools will have to be deployed to meet the challenge of climate change. That’s the perspective expressed by Daniel Bodansky, the Regents’ Professor of Law at the Sandra Day O'Connor College of Law at Arizona State University, during the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program,” a podcast produced by the Harvard Environmental Economics Program.

New forms of international cooperation and technology competition with China are the main drivers of public investment in energy innovation, though it remains insufficient to help meet climate goals.

In late 2017, Mexico made headlines as Italian company Enel bid what was then a world-record low price for renewable energy in the country’s third such energy auction. This development was possible due to the historical and sweeping energy reforms passed with broad support in Mexico in 2013. Then-President Enrique Peña Nieto had succeeded where previous Mexican presidents had failed, reversing decades of resource nationalism and overhauling the energy sector through constitutional reforms that gave the private sector a larger role and advantaged renewable energy in Mexico’s economy. The 2017 auction seemed to indicate Mexico’s bright future not only as a conventional oil producer, but also as a clean energy power.

Joseph Nye  discusses the following: Why the United States must work with China on global issues such as climate change, pandemics, and other transnational concerns, despite rivalry between the two countries; the "three-dimensional chess game" between the U.S. and China, with military, economic, and ecological boards; the importance of soft power; and differences from the U.S. relationship with the Soviet Union.

While China is building nuclear reactors faster than any other country in the world, major constraints may limit nuclear energy’s ability to grow to the scale of hundreds of gigawatts that would be required for it to play a major part in decarbonizing China’s energy system. This chapter explores the major constraints on, and risks of, large-scale nuclear energy growth in China, and how both new policies and new technologies might address them. It focuses particularly on the two biggest constraints – economics and siting. Substantial government policies to support nuclear power and advanced reactor systems designed to address some of the key constraints are both likely to be needed for nuclear to have a chance of playing a major role in decarbonizing China’s energy system; nuclear energy’s role may be bigger in the second half of this century than in the first half.
