South Asia

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.

The authors explore several approaches to an ambitious climate agreement in Paris in late 2015—including through carbon pricing.

This paper examines the strategic future of South Asia in the wake of the U.S. drawdown from Afghanistan through three key research questions: first, how does the U.S. drawdown from Afghanistan affect the regional security and economic interests of India, Pakistan, and China? Secondly, what kinds of responses to terror attacks by India, Pakistan, and China could further destabilize the region? Thirdly, what key steps can the United States take to prevent further instability in this context?

Economics are an essential part of understanding climate change and for developing solutions to it. Robert Stavins and Rohini Pande focused on that idea at a Harvard Kennedy School "IDEASpHERE" event titled "Harnessing Market Forces to Protect the Climate."

In December 2011, parties to the United Nations Framework Convention on Climate Change (UNFCCC) adopted the Durban Platform for Enhanced Action, which launched a new round of negotiations aimed at developing "a protocol, another legal instrument or an agreed outcome with legal force" for the post-2020 period. The Durban Platform negotiations got underway this year and are scheduled to conclude in 2015. This Viewpoint analyzes the elements of the Durban Platform and the possible role that a new instrument might play.

"A successful international climate policy framework will have to meet two conditions, build a coalition of countries that is potentially effective and give each member country sufficient incentives to join and remain in this coalition. Such coalition should be capable of delivering ambitious emission reduction even if some countries do not take mitigation action. In addition, it should meet the target without exceedingly high mitigation costs and deliver a net benefit to member countries as a whole. The novel contribution of this paper is mostly methodological, but it also adds a better qualification of well-known results that are policy relevant."

In pursuit of a workable successor to the Kyoto Protocol, this study offers a framework of formulas that produces precise numerical targets for emissions of carbon dioxide (CO2) and other greenhouse gases, in all regions of the world in all decades of this century....Firms, consumers, and researchers base their current decisions to invest in plant and equipment, consumer durables, or new technological possibilities on the expected future price of carbon: If government commitments are not credible from the start, then they will not raise the expected future carbon price.

The Kyoto Protocol establishes a very complex and ambitious regime, in architecture if not stringency. The problem is that relatively few states, representing only about a quarter of the world's emissions, have been willing to assume emission targets under Kyoto....The future of the Protocol thus seems doubtful at best. Even in the most optimistic scenario, a new round of emissions targets couldn't be agreed in time to prevent a legal gap between the first and second commitment periods. A possible middle ground would be to establish a transitional regime that would be political in nature, but that could evolve over time into a legally-binding regime.
