Author Cass Sunstein discusses U.S. climate change policy during the Obama administration, exploring the challenges and methods used to make changes in policy — often relying heavily on preexisting regulatory authorities.

Cooperation between U.S. and Russian nuclear scientists and engineers represents an important opportunity for rebuilding U.S.-Russian relations. The United States and Russia possess more than 90 percent of the world’s nuclear weapons, the world’s largest stocks of weapons-usable nuclear material, and the world’s largest nuclear complexes, giving them a special responsibility for nuclear security and preventing nuclear terrorism.

For a century, the geopolitics of energy has been synonymous with the
geopolitics of oil and gas. However, geopolitics and the global energy economy
are both changing. The international order predominant since the
end of World War II faces mounting challenges. At the same time, renewable
energy is growing rapidly. Nevertheless, the geopolitics of renewable
energy has received relatively little attention, especially when considering
the far-reaching consequences of a global shift to renewable energy.

The paper starts with a discussion of seven renewable energy scenarios
for the coming decades: the IEA’s World Energy Outlook 2016, the EIA’s
International Energy Outlook 2016, IRENA’s REmap 2016, Bloomberg’s
New Energy Outlook 2016, BP’s Energy Outlook 2016, Exxon-Mobil’s Outlook
for Energy 2016 and the joint IEA and IRENA G20 de-carbonization
scenario.

In this Project on Managing the Atom Discussion Paper, Philipp C. Bleek chronicles nuclear weapons proliferation choices throughout the nuclear age. Since the late 1930s and early 1940s, some thirty-one countries are known to have at least explored the possibility of establishing a nuclear weapons program. Seventeen of those countries launched weapons programs, and ten acquired deliverable nuclear weapons.

In this report, American Nuclear Diplomacy: Forging a New Consensus to Fight Climate Change and Weapons Proliferation, Former Deputy Secretary of Energy and Belfer Center Senior Fellow Daniel Poneman writes that we face two existential threats: nuclear annihilation and catastrophic climate change. Each, he says, stems from human origins. Both must be fought aggressively.

"Multiple studies confirm the grim truth that, even if all nations fulfill their Paris Climate Agreement emissions pledges, the world will still far overshoot the 2°C warming limit scientists say we must not exceed to prevent devastating climate impacts. Carbon-free nuclear energy can help close the gap. But can we expand its environmental benefits without increasing the risks of nuclear terror?"

Poneman outlines a diplomatic strategy and tough-minded, bipartisan policies to get us there.

Various policies targeting at building energy efficiency have been promulgated by the Chinese government in the past decade. However, few studies evaluate if China is on the right path to meet its energy goals through these policies by providing an assessment of their effect in reducing energy consumption in residential buildings or the feasibility of such policies to catalyze these reductions. This paper attempts to fill this gap by systematically quantifying (1) the energy savings catalyzed by existing policy instruments; (2) the additional energy savings that could be realized by strengthening these policies; and (3) the relative advantages of each policy.

In this new report, Preventing Nuclear Terrorism: Continuous Improvement or Dangerous Decline?, Matthew Bunn, Martin Malin, Nickolas Roth, and William Tobey provide a global reality check on nuclear security. They note that effective and sustainable nuclear security capable of addressing plausible threats is the single most effective chokepoint preventing terrorists from acquiring a nuclear weapon.

This paper distills core lessons about how researchers (scientists, engineers, planners, etc.) interested in promoting sustainable development can increase the likelihood of producing usable knowledge. We draw the lessons from both practical experience in diverse contexts around the world, and from scholarly advances in understanding the relationships between science and society.

"One category of nuclear material that has not yet been adequately addressed throughout recent Nuclear Security Summits is military stockpiles.2 Instead, the Summit process has focused primarily on reducing the risk of civilian nuclear material theft..."

The Energy Technology Innovation Policy research group at the Harvard Kennedy School and the Tsinghua School of Public Policy and Management convened a workshop at Tsinghua University in Beijing on June 18–19, 2015 to build on the momentum created by the U.S.-China joint emissions agreement and the upcoming Paris negotiations. The objective of the Workshop was to discuss the current state of affairs in China, in the United States, and in selected other countries as well as academic research on: (1) the funding and allocation of government investments in R&D, with a particular focus in energy; (2) the impact of policy on private sector innovation in energy; and (3) the management of publicly funded R&D organizations.
