Deep Decarbonization Roadmap for the Cement and Concrete Industries in California

| September 2019

Cement production is one of the most energy-intensive and highest carbon dioxide (CO2) emitting manufacturing processes. The goal of this study is to develop a roadmap for decarbonization of California's cement and concrete production. In this study, the authors look at the current status of cement and concrete production in California and develop scenarios up to 2040 to analyze different decarbonization levers that can help to reduce CO2 emissions of cement and concrete production in California.

Deescalation Wanted: How Trump Can Steer Clear of a War

| June 26, 2019

The United States and Iran have engaged in a constant raising of the stakes as a means of securing leverage ahead of possible nuclear negotiations. This is a classic bargaining pattern but in the current context, such an approach is particularly risky due to the potential for misperceptions. The complexities of domestic and regional dynamics are also a factor. In such a situation, absent clear understanding of the other’s motivations and tactics, raising the stakes—rather than securing leverage for effective negotiations—could steer the United States and Iran towards a path toward war.

Combating Nuclear Smuggling? Exploring Drivers and Challenges to Detecting Nuclear and Radiological Materials at Maritime Facilities

| June 03, 2019

International concern over nuclear terrorism has grown during the past few decades. This has driven a broad spectrum of efforts to strengthen nuclear security globally, including the widespread adoption of radiation-detection technology for border monitoring. Detection systems are now deployed at strategic locations for the purported purpose of detecting and deterring the smuggling of nuclear and radioactive materials. However, despite considerable investment in this area, few studies have examined how these programs are implemented or the operational challenges they face on a day-to-day basis. This article seeks to address this with a focus on radiation-detection efforts at maritime facilities. Utilizing practitioner interviews and a survey, this article identifies the factors that influence the planning and use of these systems in this fast-moving environment. The results clearly demonstrate that the implementation of these systems varies significantly across different national and organizational contexts, resulting in a fragmented global nuclear-detection architecture, which arguably undermines efforts to detect trafficked nuclear-threat materials. Greater consideration should therefore be given to developing international standards and guidance, designing and adopting tools to support key parts of the alarm assessment process, and broader sharing of good practice.

China's Calculus After the INF Treaty

| May 08, 2019

It seems that the Intermediate-Range Nuclear Forces (INF) Treaty is coming to an end. The Treaty prohibits the United States and Russia from possessing, producing or testing land-based ballistic and cruise missiles with ranges of 500–5500 kilometres, including both conventional and nuclear-armed missiles. On 1 February 2019, US President Trump said that he would suspend obligations under the INF Treaty and initiate the withdrawal procedure. After withdrawing, the United States might deploy conventional and nuclear missiles to the West Pacific against China. How would the potential deployment of each missile type impact China’s security?

Senator Richard G. Lugar: An Appreciation

| Apr. 30, 2019

Sen. Richard Lugar—with his legislative partner, Sen. Sam Nunn—imagined the unimaginable. He championed a program to provide assistance to military forces in the former Soviet republics holding tens of thousands of nuclear, chemical, and biological weapons aimed at the United States and our allies, shortly after America’s existential enemy, the Soviet Union, expired. All told, the Nunn-Lugar cooperative threat reduction program provided more than $14 billion to, among other things, deactivate 13,300 nuclear warheads, eliminate 1,473 intercontinental ballistic missiles, and destroy almost 40,000 metric tons of chemical agents. The US departments of Defense and Energy also worked with Russia to improve security at 148 sites still holding nuclear weapons or weapons-grade material from Murmansk to Kamchatka.

The Future of the Nuclear Order

| April 2019

Foreign policy pundits have bemoaned the unraveling of the post-World War II international order in recent years, describing threats to the multilateralism and liberalism enshrined in postwar institutions. An often overlooked component of that structure is the global nuclear order, which, like other parts of the postwar system, was created for magnanimous and selfish aims: reducing the dangers of nuclear weapons for all and serving the interests of the world’s most powerful states.

Dim Hope for Disarmament and Approaching Risk of Build-Up

| March 2019

Further nuclear reduction under the current regimes seems unlikely. The US argues that Russia has violated the INF Treaty by developing and deploying a land-based cruise missile. Russia also makes the accusation that the Aegis Ashore missile defense system in Europe, capable of launching cruise missiles, has violated the INF. Furthermore, President Trump has repeatedly expressed his unwillingness to extend the New START Treaty for five more years after it expires in February 2021. The US-Russia bilateral disarmament process seems to have terminated. There have been some signs of nuclear build-up. The new US Nuclear Posture Review emphasizes the role of nuclear weapons while de-emphasizing strategic stability, reduces the threshold for nuclear use and calls for developing new low-yield SLBM and sea-launched cruise missiles. America’s nuclear policy might stimulate Russia and China to build new nuclear capabilities. North Korea’s advances in nuclear and long-range missile programs justify Washington’s investment in homeland missile defense, which in turn undermines China and Russia’s nuclear retaliatory capability and might result in a defense-offense arms race.

Can a small nuclear weapon really make the world safer? In this installment of “Say WHAT?”—the Bulletin video series that casts a clear eye on fuzzy policy—we ask nuclear weapons expert Sébastien Philippe what he thinks about the latest nuclear craze.

Revitalizing Nuclear Security in an Era of Uncertainty

| January 2019

Nuclear security around the world has improved dramatically over the last three decades—which demonstrates that with focused leadership, major progress is possible. But important weaknesses remain, and the evolution of the threat remains unpredictable. The danger that terrorists could get and use a nuclear bomb, or sabotage a major nuclear facility, or spread dangerous radioactive material in a “dirty bomb,” remains too high. The United States and countries around the world need to join together and provide the leadership and resources needed to put global nuclear security on a sustained path of continuous improvement, in the never-ending search for excellence in performance.
