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.

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.”

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.

The success of U.S. President Joe Biden's China policy will depend on whether the two powers can cooperate in producing global public goods, while competing in other areas. The U.S.-China relationship is a "cooperative rivalry," in which the terms of competition will require equal attention to both sides of the oxymoron.  Joseph Nye argues that it will not be easy.

This study provides a whole-systems simulation on how to halve global CO2 emissions by 2050, compared to 2010, with an emphasis on technologies and costs, in order to avoid a dangerous increase in the global mean surface temperature by end the of this century.

Joel Clement writes that the federal government must allow community voices to drive infrastructure investment  and conservation in the North.

Professor Joseph Aldy says the incoming U.S. administration can breathe new life into global efforts against climate change, but faces daunting political and economic obstacles.
