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.

In its push for greener energy, Washington is giving biofuels a boost. But just how green are they? Daniel Schrag, Co-Director of the Science, Technology, and Public Policy Program, argued the case for biofuels, opposite Carlisle Ford Runge, who argued against them.

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.

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.”

Carbon capture, utilization, and storage (CCUS) is very likely to be a key technology for achieving the Biden administration's goal of net-zero greenhouse gas emissions by 2050. But absent regulation requiring its use, CCUS needs to become more economical in order for deployment in the United States to expand significantly.

This paper provides an overview on the main impacts of biofuels production on water resources within the United States, with an emphasis on the corn-based ethanol market and the agricultural stage. The following issues are examined:

• the relationship between biofuel production and water availability;
• trends and policy options for future biofuel production and the tradeoffs for water scarcity;
• technological changes in transportation fleet, with consequential effects on biofuels demand and water resources;
• considerations for policy makers who seek to reduce the future impact of biofuels on water sustainability.

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.
