Joseph Nye considers lessons from his own work on preventing the spread of nuclear technology in the 1970s.

Energy economist Karen Palmer, renowned for her research on the nation’s electric power sector, shared her insights on electricity regulation and deregulation, carbon pricing, and climate change policy in the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program.”

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.

Joshua Schwartz and Sabrina Arias write that although Congress seems unable to act, enough states, cities and counties are mobilizing to make a dent in U.S. carbon emissions. The states, cities, counties, and towns that have committed themselves to upholding the Paris agreement currently release a majority of U.S. carbon emissions. If they do manage to meet their targets, they can make a meaningful difference.

Last week, U.S. Sen. Joe Manchin seemingly dashed Democrats’ hopes for congressional action to slow climate change. Sen. Bernie Sanders accused Manchin of “sabotag[ing] the president’s agenda”; Rep. John Yarmuth, when asked about the consequences of Congress not acting on climate change, said, “We’re all going to die”; and climate activists, as well as some Democrats in Congress, wondered if Manchin should be removed as chair of the Senate Energy and Natural Resources Committee.

For many, integrating “decarbonization” into public policy, corporate and financial strategies has become a requirement, not an option — yet, what happens when the critical link between climate stability and decarbonization breaks?

Paul Joskow, the Elizabeth and James Killian Professor of Economics emeritus at MIT and former President and CEO of the Alfred P. Sloan Foundation in New York City, shared his thoughts on U.S. regulatory economics and climate change policy in the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program.”

To accelerate the global transition to a low-carbon economy, all energy systems must be actively decarbonized. While hydrogen has been a staple in the energy and chemical industries for decades, clean hydrogen – defined as hydrogen produced from water electrolysis with zero-carbon electricity – has captured increasing political and business momentum as a versatile and sustainable energy carrier in the future carbon-free energy puzzle.

Kelly Sims Gallagher asserts that politicians' pledges of dramatic long-term reductions should not let them off the hook for their failure to achieve more modest progress in the short term.

Ian Masters and Joel Clement assess how much time has been lost by governments in facing the looming crisis of climate change, in particular here in the U.S. where the last four years were not only wasted, but were steps backwards from the urgent challenges made clear by yesterday's alarming IPCC report.
