Environment & Climate Change

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.

Verification is a crucial part of all arms control agreements, from the Intermediate-Range Nuclear Forces Treaty in the 1980s to the recent Iran nuclear deal, U.S. Energy Secretary Ernest Moniz explained during a recent appearance at Harvard. And it is on verification where scientists can be decisive.

"Chinese President Xi Jinping reaffirmed at the global climate change conference in Paris that China pledged to achieve peak carbon dioxide emissions by around 2030, and to get around 20 percent of its primary energy from non-fossil sources by 2030. In 2014, China’s non-fossil energy consumption accounted for 11.2 percent of total energy use—hydro power was 8 percent, nuclear power was about 1 percent, and non-hydro renewable energy was around 2 percent—which is very close to the target of 11.4 percent set for 2015. Still, coal supplied the majority (66 percent) of China's total energy consumption in 2014, and oil accounted for about 18 percent of the energy mix. Natural gas, at 5 percent, still accounted for a relatively small share. To double the share of non-fossil sources by 2030, what role can nuclear power play?"

The Project on Managing the Atom offers fellowships for pre-doctoral, post-doctoral, and mid-career researchers for one year, with a possibility for renewal, in the stimulating environment of the Belfer Center for Science and International Affairs at the Harvard Kennedy School. The online application for 2016-2017 fellowships opened December 15, 2015, and the application deadline is January 15, 2016. Recommendation letters are due by February 1, 2016.

On April 28, the Project on Managing the Atom joined the James Martin Center for Nonproliferation Studies at the Middlebury Institute of International Studies at Monterey, The Netherlands government, and the United Nations Office for Disarmament Affairs (UNODA) in convening nuclear nonproliferation experts from around the world at the United Nations to participate in a Symposium on the 2015 Nonproliferation Treaty (NPT) Review Conference.

Our faculty and fellows are immersed in studying and solving some of the world's toughtest policy challenges. Amid that sobering work, they sometimes spot positive developments. We asked them to share these findings in this new feature.
