Deploying coal-bioenergy gasification systems with carbon capture and storage (CBECCS) provides a promising opportunity for China to realize its carbon mitigation and air pollution abatement goals simultaneously. The authors conducted a comprehensive assessment of CBECCS technology for China, with a focus on plant and fuel configurations (e.g., biomass ratios) and economics, as well as CO2 and greenhouse gas emissions and cobenefits for air quality.

Bound to Fail: The Rise and Fall of the Liberal International Order

| Spring 2019

The liberal international order led by the United States was destined to collapse. Liberal excesses provoked a powerful nationalist backlash. In the emerging multipolar world, a realist order will manage the world economy, and Chinese-led and U.S.-led bounded orders will help the two great powers prosecute their security competition.

Proliferation and the Logic of the Nuclear Market

| Spring 2019

What explains the scale and speed of nuclear proliferation? One key factor is the level of competition among suppliers in the market for nuclear materials and technologies. When suppliers form a cartel, fewer countries can acquire what they need for a nuclear weapons program. If great power competition intensifies, suppliers will find it harder to cooperate and nuclear proliferation could accelerate.

Buying Allies: Payment Practices in Multilateral Military Coalition-Building

    Author:
  • Marina E. Henke
| Spring 2019

Many states have been paid to join multilateral military coalitions. These payments are largely covered by “pivotal states”—those that care the most about an operation’s success—and take the form of deployment subsidies and political side deals to attract critical contributors to the mission.

Power and Profit at Sea: The Rise of the West in the Making of the International System

Beginning in the 1400s, Europeans built the global international system by using naval force to achieve commercial success. Europeans had a technical capacity and a cultural inclination to control the seas that Eastern empires lacked.

Les États-Unis et La Chine Se Dirigent Tout Droit Vers La Guerre

| May 03, 2019

Le piège de Thucydides se met en place quand une puissance émergente vient défier la puissance régnante. Ainsi hier Athènes face à Sparte. Et peut-être demain Pékin face à Washington. Telle est la thèse de Graham Allison, professeur émérite à Harvard et conseiller de plusieurs secrétaires d'État à la Défense, dans son livre devenu un best-seller mondial.

(The Thucydides Trap takes place when an emerging power threatens to displace a ruling one. Long ago, in antiquity, it was Athens against Sparta. But tomorrow, it could be Beijing against Washington. Such is the argument made by Graham Allison, emeritus professor at Harvard and advisor to several Secretaries of Defense, in his best-selling book Destined for War: Can America and China Escape the Thucydides Trap? - This English translation from original French by Christian Gibbons, Belfer Center)

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.
