Environment & Climate Change

As assistant to the president for science and technology, director of the White House Office for Science and Technology Policy, and co-chair of the President’s Council of Advisors on Science and Technology (PCAST), Holdren has worked closely with Obama to reinvigorate America’s scientific capabilities on a range of policy fronts, from climate change and renewable energy to health care and nanotechnology.

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.

Senior Fellow of the Future of Diplomacy Project, David Ignatius examines the Navy’s energy diet that began seven years ago with an edict from newly appointed Secretary Ray Mabus, who issued five goals for radically changing how the Navy bought and consumed fuel.

As India’s civilian nuclear energy program expands with the assistance of international nuclear suppliers, it creates new potential pathways to the acquisition of fissile material that could be diverted for military purposes. A key question is whether and how India’s civilian and military nuclear facilities are separated. In this discussion paper from the Belfer Center’s Project on Managing the Atom, Kalman A. Robertson and John Carlson argue that India has not established a complete and verifiable separation of its civilian and military nuclear programs. The authors recommend steps for India to take under its safeguards agreement with the International Atomic Energy Agency to provide assurances to all states that components of its civilian program are not contributing to the growth of its nuclear arsenal. These steps include renouncing options that would facilitate the use of safeguarded items to produce unsafeguarded nuclear material, and placing the proliferation-sensitive components of its nuclear power industry under continuous safeguards.

Was the Paris Climate Conference of 2015 a key step in stopping climate change? We asked the Belfer Center's Robert Stavins and David Keith to give us their answers to that question. They agreed to disagree in some of their answers and comments.

"One of the dramas playing out this month in New York at the 2015 Review Conference for parties to the Treaty on the Non-proliferation of Nuclear Weapons (NPT) concerns the future of discussions on establishing the weapons of mass destruction free zone in the Middle East..."
