Stochastic Cost-benefit Analysis of Urban Waste-to-Energy Systems

Municipal solid waste generation is a rapidly increasing challenge that is leading to severe pollution and environmental degradation in many urban areas of developing countries. This study presents the Waste to Energy Recovery Assessment (WERA) framework, a new quantitative decision support model for initial evaluation and alternative comparisons of different thermochemical treatments of municipal wastes. The framework is used to study waste-to-energy (WtE) systems for Abu Dhabi, Riyadh, Tokyo, and New York. The results show that WtE systems can fulfill only 1.4–3.6% of 2014 electricity demand in the analyzed cases.

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.

Nonproliferation and Security Implications of the Evolving Civil Nuclear Export Market

| Mar. 27, 2019

In recent decades, the nuclear export market has observed a marked shift of demand from traditional customers in the Western world to Asia. The lack of projects in the United States, the delay in the French construction of advanced reactors, and the Fukushima accident in Japan have also led to the declining export capabilities of their companies. In contrast, Russia has gained numerous contracts, and China will likely become another major exporter. In this paper, the evolution of the market was examined from both the supply and demand sides with issues including the more concentrated and uncertain market, the lack of full participation by emerging suppliers to the nonproliferation regime, and the lesser governance capabilities of the newcomers. Addressing these issues, a range of policy suggestions was made, including the reinforcement of market shares of Western suppliers, the encouragement of newcomers to adhere to international norms, and a better safeguards contribution scheme.

Emerging Non-Nuclear Technology and the Future of the Global Nuclear Order

| March 2019

The latest information revolution has driven the development of a new suite of non-nuclear military capabilities and a new technological context that together challenge our understanding of the global nuclear order. Long-held assumptions about strategic stability, deterrence, arms control and crisis stability are being challenged by increasingly capable ballistic missile defences, precision weapons across all military domains, cyber technologies and the introduction of Artificial Intelligence into the nuclear realm. Each of these systems is important and influential in its own right – particularly as counter-force weapons – but, taken together, the impact is magnified considerably. The time is therefore ripe to reassess the central tenets of how we think about and manage our nuclear world and unpack what this development could mean for the future of nuclear weapons, and how this might shape the prospect for the long-held goal of nuclear disarmament. This chapter argues that we stand on the cusp of a new era likely to be characterised by three pathways, only one of which might see us move towards a non-nuclear world.

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.

Nuclear Disarmament, Nuclear Energy, and Climate Change

| March 2019

Preventing nuclear war and avoiding catastrophic climate change are two of the most basic challenges facing human civilization in the twenty-first century. While these are separate issues, these challenges are linked in several ways, and both may be affected by the future of nuclear energy. For nuclear energy to provide any substantial part of the low-carbon energy needed in the second half of the twenty-first century would require dramatic growth. This chapter provides an overview of the constraints and risks of nuclear energy growth on that scale, and the necessary steps to address them. In particular, use of nuclear energy at that scale would place unprecedented demands on global systems for verification, control, and security for weapons-usable nuclear materials. Deep reductions in nuclear arms and their eventual prohibition will also require new approaches to managing the vast global stocks of weapons-usable nuclear materials. Politically, nuclear energy may not be able to grow on the scale required unless governments and publics are confident that it will not contribute to the spread of nuclear weapons, creating another link between climate mitigation and nuclear nonproliferation and disarmament.
